PRESERVATION SYSTEM FOR NUTRITIONAL SUBSTANCES

FIELD OF THE INVENTION

The present inventions relate to creation, collection, transmission, and use of information regarding the preservation of nutritional substances.

BACKGROUND OF THE INVENTION

Nutritional substances are traditionally grown (plants), raised (animals) or synthesized (synthetic compounds). Additionally, nutritional substances can be found in a wild, non-cultivated form, which can be caught or collected. While the collectors and creators of nutritional substances generally obtain and/or generate information about the source, history, caloric content and/or nutritional content of their products, they generally do not pass such information along to the users of their products. One reason is the nutritional substance industries have tended to act like “silo” industries. Each group in the food and beverage industry: growers, packagers, processors, distributors, retailers, and preparers work separately, and either shares no information, or very little information, between themselves. There is generally no consumer access to, and little traceability of, information regarding the creation and/or origin, preservation, processing, preparation, or consumption of nutritional substances. It would be desirable for such information be available to the consumers of nutritional substances, as well as all participants in the food and beverage industry—the nutritional substance supply system.

While the nutritional substance supply system has endeavored over the last 50 years to increase the caloric content of nutritional substances produced (which has helped reduce starvation in developing countries, but has led to obesity and other problems in developed countries), maintaining, or increasing, the nutritional content of nutritional substances has been a lower priority and is done in a synthetic manner. Caloric content refers to the energy in nutritional substances, commonly measured in calories. The caloric content could be represented as sugars and/or carbohydrates in the nutritional substances. The nutritional content, also referred to herein as nutritional value, of foods and beverages, as used herein, refers to the non-caloric content of these nutritional substances which are beneficial to the organisms which consume these nutritional substances. For example, the nutritional content of a nutritional substance could include vitamins, minerals, proteins, and other non-caloric components which are necessary, or at least beneficial, to the organism consuming the nutritional substances.

While there has recently been greater attention by consumer organizations, health organizations and the public to the nutritional content of foods and beverages, the food and beverage industry has been slow in responding to this attention. One reason for this may be that since the food and beverage industry operates as silos of those who create nutritional substances, those who preserve and transport nutritional substances, those who transform nutritional substances, and those who finally prepare the nutritional substances for consumption by the consumer, there has been no system wide coordination or management of nutritional content, and no practical way for creators, preservers, transformers, and conditioners to update labeling content for nutritional substances. While each of these silo industries may be able to maintain or increase the nutritional content of the foods and beverages they handle, each silo industry has only limited information and control of the nutritional substances they receive, and the nutritional substances they pass along.

As consumers better understand their need for nutritional substances with higher nutritional content, they will start demanding that the food and beverage industry offer products which include higher nutritional content, and/or at least information regarding nutritional content of such products, as well as information regarding the source, creation and other origin information for the nutritional substance. In fact, consumers are already willing to pay higher prices for higher nutritional content. This can be seen at high-end grocery stores which offer organic, minimally processed, fresh, non-adulterated nutritional substances. Further, as societies and governments seek to improve their constituents' health and lower healthcare costs, incentives and/or mandates will be given to the food and beverage industry to track, maintain, and/or increase the nutritional content of nutritional substances they handle. There will be a need, not only within each food and beverage industry silo to maintain or improve the nutritional content of their products, but an industry-wide solution to allow the management of nutritional content across the entire cycle from creation to consumption. In order to manage the nutritional content of nutritional substances across the entire cycle from creation to consumption, the nutritional substance industry will need to identify, track, measure, estimate, preserve, transform, condition, and record nutritional content for nutritional substances. Of particular importance is the measurement, estimation, and tracking of changes to the nutritional content of a nutritional substance from creation to consumption. This information could be used, not only by the consumer in selecting particular nutritional substances to consume, but could be used by the other food and beverage industry silos, including creation, preservation, transformation, and conditioning, to make decisions on how to create, handle and process nutritional substances. Additionally, those who sell nutritional substances to consumers, such as restaurants and grocery stores, could communicate perceived qualitative values of the nutritional substance in their efforts to market and position their nutritional substance products. Further, a determinant of price of the nutritional substance could be particular nutritional, organoleptic, or aesthetic values, and if changes to those values are perceived as desirable. For example, if a desirable value has been maintained, improved, or minimally degraded, it could be marketed as a premium product. Still further, a system allowing creators, preservers, transformers, and conditioners of nutritional substances to update labeling content to reflect the most current information about the nutritional substance would provide consumers with the information they need to make informed decisions regarding the nutritional substances they purchase and consume. Such information updates could include nutritional, organoleptic, or aesthetic values of the nutritional substance, and may further include information regarding the source, creation and other origin information for the nutritional substance.

For example, the grower of sweet corn generally only provides basic information as the variety and grade of its corn to the packager, who preserves and ships the corn to a producer for use in a ready-to-eat dinner. The packager may only tell the producer that the corn has been frozen as loose kernels of sweet corn. The producer may only provide the consumer with rudimentary instructions how to cook or reheat the ready-to-eat dinner in a microwave oven, toaster oven or conventional oven, and only tell the consumer that the dinner contains whole kernel corn among the various items in the dinner. Finally, the consumer of the dinner will likely keep her opinions on the quality of the dinner to herself, unless it was an especially bad experience, where she might contact the producer's customer support program to complain. Very minimal, or no, information on the nutritional content of the ready-to-eat dinner is passed along to the consumer. The consumer knows essentially nothing about changes (generally a degradation, but could be a maintenance or even an improvement) to the nutritional content of the sweet corn from creation, processing, packaging, cooking, preservation, preparation by consumer, and finally consumption by the consumer. The consumer is even more unlikely to be aware of possible changes to labeling content that a creator, preserver, transformer, or conditioner may just have become be aware of, such as changes in information about nutritional, organoleptic, or aesthetic values of the nutritional substance or changes in information regarding the source, creation and other origin information about the nutritional substance. If communicated, such changes to labeling content could affect a purchasing preference or consumption preference of a consumer. Further, if communicated, such changes to labeling content could affect the health, safety, and wellbeing of the consumer. It is also clear that such changes would best be communicated rapidly and by a means readily utilized by a consumer.

Consumers' needs are changing as consumers are demanding healthier foods, such as “organic foods.” Consumers are also asking for more information about the nutritional substances they consume, such as specific characteristics' relating not only to nutritional content, but to allergens or digestive intolerances. For example, nutritional substances which contain lactose, gluten, nuts, dyes, etc. need to be avoided by certain consumers. However, the producer of the ready-to-eat dinner, in the prior example, has very little information to share other than possibly the source of the elements of the ready-to-eat dinner and its processing steps in preparing the dinner. Generally, the producer of the ready-to-eat dinner does not know the nutritional content and organoleptic state and aesthetic condition of the product after it has been reheated or cooked by the consumer, cannot predict changes to these properties, and cannot inform a consumer of this information to enable the consumer to better meet their needs. For example, the consumer may want to know what proportion of desired organoleptic properties or values, desired nutritional content or values, or desired aesthetic properties or values of the corn in the ready-to-eat dinner remain after cooking or reheating, and the change in the desired nutritional content or values, the desired organoleptic properties or values, or the desired aesthetic properties or values (usually a degradation, but could be a maintenance or even improvement). There is a need to preserve, measure, estimate, store and/or transmit information regarding such nutritional, organoleptic, and aesthetic values, including changes to these values, throughout the nutritional substance supply system. Given the opportunity and a system capable of receiving and processing real time consumer feedback and updates regarding changes in the nutritional, organoleptic, and/or aesthetic value of nutritional substances, consumers can even play a role in updating dynamic information about the nutritional substances they have purchased and/or prepared for consumption, such that that information is available and useful to others in the nutritional substance supply system.

The caloric and nutritional content information for a prepared food that is provided to the consumer is often minimal. For example, when sugar is listed in the ingredient list, the consumer generally does receive any information about the source of the sugar, which can come from a variety of plants, such as sugarcane, beets, or corn, which will affect its nutritional content. Conversely, some nutritional information that is provided to consumers is so detailed, the consumer can do little with it. For example, this of ingredients is from a nutritional label on a consumer product: Vitamins—A 355 IU 7%, E 0.8 mg 4%, K 0.5 mcg, 1%, Thiamin 0.6 mg 43%, Riboflavin 0.3 mg 20%, Niacin 6.0 mg 30%, B6 1.0 mg 52%, Foliate 31.5 mcg 8%, Pantothenic 7%; Minerals Calcium 11.6 1%, Iron 4.5 mg 25%, Phosphorus 349 mg 35%, Potassium 476 mg 14%, Sodium 58.1 mg 2%, Zinc 3.7 mg 24%, Copper 0.5 mg 26%, Manganese 0.8 mg 40%, Selenium 25.7 mcg 37%; Carbohydrate 123 g, Dietary fiber 12.1 g, Saturated fat 7.9 g, Monosaturated Fat 2.1 g, Polysaturated Fat 3.6 g, Omega 3 fatty acids 108 g, Omega 6 fatty acids 3481, Ash 2.0 g and Water 17.2 g. (%=Daily Value). There is a need to provide information about nutritional substances in a meaningful manner. Such information needs to be presented in a manner that meets the specific needs of a particular consumer. For example, consumers with a medical condition, such as diabetes, would want to track specific information regarding nutritional values associated with sugar and other nutrients in the foods and beverages they consume, and would benefit further from knowing changes in these values or having tools to quickly indicate or estimate these changes in a retrospective, current, or prospective fashion, and even tools to report these changes, or impressions of these changes, in a real-time fashion.

In fact, each silo in the food and beverage industry already creates and tracks some information, including caloric and nutritional information, about their product internally. For example, the famer who grew the corn knows the variety of the seed, condition of the soil, the source of the water, the fertilizers and pesticides used, and can measure the caloric and nutritional content at creation. The packager of the corn knows when it was picked, how it was transported to the packaging plant, how the corn was preserved and packaged before being sent to the ready-to-eat dinner producer, when it was delivered to the producer, and what degradation to caloric and nutritional content has occurred. The producer knows the source of each element of the ready-to-eat dinner, how it was processed, including the recipe followed, and how it was preserved and packaged for the consumer. Not only does such a producer know what degradation to caloric and nutritional content occurred, the producer can modify its processing and post-processing preservation to minimally affect nutritional content. The preparation of the nutritional substance for consumption can also degrade the nutritional content of nutritional substances. Finally, the consumer knows how she prepared the dinner, what condiments were added, and whether she did or did not enjoy it.

If there was a mechanism to share this information, the quality of the nutritional substances, including caloric and nutritional, organoleptic, and aesthetic value, could be preserved and improved. Consumers could be better informed about nutritional substances they select and consume, including the state, and changes in the state, of the nutritional substance throughout its lifecycle from creation to consumption. The efficiency and cost effectiveness of nutritional substances could also be improved. Feedback within the entire chain from creator to consumer could provide a closed-loop system that could improve quality (taste, appearance, and caloric and nutritional content), efficiency, value and profit. For example, in the milk supply chain, at least 10% of the milk produced is wasted due to safety margins included in product expiration dates. The use of more accurate tracking information, measured quality (including nutritional content) information, and historical environmental information could substantially reduce such waste. Collecting, preserving, measuring and/or tracking information about a nutritional substance in the nutritional substance supply system, would allow needed accountability. There would be nothing to hide.

As consumers are demanding more information about what they consume, they are asking for products that have higher and better nutritional content and more closely match good nutritional requirements, and would like nutritional products to actually meet their specific nutritional requirements. While grocery stores, restaurants, and all those who process and sell food and beverages may obtain some information from current nutritional substance tracking systems, such as labels, these current systems can provide only limited information.

Current packaging materials for nutritional substances include plastics, paper, cardboard, glass, and synthetic materials. Generally, the packaging material is chosen by the producer to best preserve the quality of the nutritional substance until used by the customer. In some cases, the packaging may include some information regarding type of nutritional substance, identity of the producer, and the country of origin. Such packaging generally does not transmit source information of the nutritional substance, such as creation information, current or historic information as to the external conditions of the packaged nutritional substance, or current or historic information as to the internal conditions of the packaged nutritional substance.

An important issue in the creation, preservation, transformation, conditioning, and consumption of nutritional substances are the changes that occur in nutritional substances due to a variety of internal and external factors. Because nutritional substances are composed of biological, organic, and/or chemical compounds, they are generally subject to degradation. This degradation generally reduces the nutritional, organoleptic, and/or aesthetic values of nutritional substances. While not always true, nutritional substances are best consumed at their point of creation. However, being able to consume nutritional substances at the farm, at the slaughterhouse, at the fishery, or at the food processing plant is at least inconvenient, if not impossible. Currently, the food and beverage industry attempts to minimize the loss of nutritional, organoleptic, and/or aesthetic value (often through the use of additives or preservatives and often through freezing the nutritional substance), and/or attempts to hide this loss of nutritional, organoleptic, and/or aesthetic value from consumers.

Overall, the examples herein of some prior or related systems and their associated limitations are intended to be illustrative and not exclusive. Other limitations of existing or prior systems will become apparent to those of skill in the art upon reading the following Detailed Description.

DETAILED DESCRIPTION OF THE INVENTION

Various examples of the invention will now be described. The following description provides specific details for a thorough understanding and enabling description of these examples. One skilled in the relevant art will understand, however, that the invention may be practiced without many of these details. Likewise, one skilled in the relevant art will also understand that the invention can include many other obvious features not described in detail herein. Additionally, some well-known structures or functions may not be shown or described in detail below, so as to avoid unnecessarily obscuring the relevant description.

The terminology used below is to be interpreted in its broadest reasonable manner, even though it is being used in conjunction with a detailed description of certain specific examples of the invention. Indeed, certain terms may even be emphasized below; however, any terminology intended to be interpreted in any restricted manner will be overtly and specifically defined as such in this Detailed Description section.

The following discussion provides a brief, general description of a representative environment in which the invention can be implemented. Although not required, aspects of the invention may be described below in the general context of computer-executable instructions, such as routines executed by a general-purpose data processing device (e.g., a server computer or a personal computer). Those skilled in the relevant art will appreciate that the invention can be practiced with other communications, data processing, or computer system configurations, including: wireless devices, Internet appliances, hand-held devices (including personal digital assistants (PDAs)), wearable computers, all manner of cellular or mobile phones, multi-processor systems, microprocessor-based or programmable consumer electronics, set-top boxes, network PCs, mini-computers, mainframe computers, and the like. Indeed, the terms “controller,” “computer,” “server,” and the like are used interchangeably herein, and may refer to any of the above devices and systems.

While aspects of the invention, such as certain functions, are described as being performed exclusively on a single device, the invention can also be practiced in distributed environments where functions or modules are shared among disparate processing devices. The disparate processing devices are linked through a communications network, such as a Local Area Network (LAN), Wide Area Network (WAN), or the Internet. In a distributed computing environment, program modules may be located in both local and remote memory storage devices.

Aspects of the invention may be stored or distributed on tangible computer-readable media, including magnetically or optically readable computer discs, hard-wired or preprogrammed chips (e.g., EEPROM semiconductor chips), nanotechnology memory, biological memory, or other data storage media. Alternatively, computer implemented instructions, data structures, screen displays, and other data related to the invention may be distributed over the Internet or over other networks (including wireless networks), on a propagated signal on a propagation medium (e.g., an electromagnetic wave(s), a sound wave, etc.) over a period of time. In some implementations, the data may be provided on any analog or digital network (packet switched, circuit switched, or other scheme).

In some instances, the interconnection between modules is the internet, allowing the modules (with, for example, WiFi capability) to access web content offered through various web servers. The network may be any type of cellular, IP-based or converged telecommunications network, including but not limited to Global System for Mobile Communications (GSM), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), Orthogonal Frequency Division Multiple Access (OFDM), General Packet Radio Service (GPRS), Enhanced Data GSM Environment (EDGE), Advanced Mobile Phone System (AMPS), Worldwide Interoperability for Microwave Access (WiMAX), Universal Mobile Telecommunications System (UMTS), Evolution-Data Optimized (EVDO), Long Term Evolution (LTE), Ultra Mobile Broadband (UMB), Voice over Internet Protocol (VoIP), Unlicensed Mobile Access (UMA), etc.

The modules in the systems can be understood to be integrated in some instances and in particular embodiments, only particular modules may be interconnected.

FIG. 1 shows the components of a nutritional substance industry 10. It should be understood that this could be the food and beverage ecosystem for human consumption, but could also be the feed industry for animal consumption, such as the pet food industry. A goal of the present invention for nutritional substance industry 10 is to create, preserve, transform and trace the change in nutritional, organoleptic and/or aesthetic values of nutritional substances, collectively and individually also referred to herein as ΔN, through their creation, preservation, transformation, conditioning and consumption. While the nutritional substance industry 10 can be composed of many companies or businesses, it can also be integrated into combinations of business serving many roles, or can be one business or even individual. Since ΔN is a measure of the change in a value of a nutritional substance, knowledge of a prior value (or state) of a nutritional substance and the ΔN value will provide knowledge of the changed value (or state) of a nutritional substance, and can further provide the ability to estimate a change in value (or state).

Module 200 is the creation module. This can be a system, organization, or individual which creates and/or originates nutritional substances. Examples of this module include a farm which grows produce; a ranch which raises beef; an aquaculture farm for growing shrimp; a factory that synthesizes nutritional compounds; a collector of wild truffles; or a deep sea crab trawler.

Preservation module 300 is a preservation system for preserving and protecting the nutritional substances created by creation module 200. Once the nutritional substance has been created, generally, it will need to be packaged in some manner for its transition to other modules in the nutritional substances industry 10. While preservation module 300 is shown in a particular position in the nutritional substance industry 10, following the creation module 200, it should be understood that the preservation module 300 actually can be placed anywhere nutritional substances need to be preserved during their transition from creation to consumption.

Transformation module 400 is a nutritional substance processing system, such as a manufacturer who processes raw materials such as grains into breakfast cereals. Transformation module 400 could also be a ready-to-eat dinner manufacturer who receives the components, or ingredients, also referred to herein as component nutritional substances, for a ready-to-eat dinner from preservation module 300 and prepares them into a frozen dinner. While transformation module 400 is depicted as one module, it will be understood that nutritional substances may be transformed by a number of transformation modules 400 on their path to consumption.

Conditioning module 500 is a consumer preparation system for preparing the nutritional substance immediately before consumption by the consumer. Conditioning module 500 can be a microwave oven, a blender, a toaster, a convection oven, a cook, etc. It can also be systems used by commercial establishments to prepare nutritional substance for consumers such as a restaurant, an espresso maker, pizza oven, and other devices located at businesses which provide nutritional substances to consumers. Such nutritional substances could be for consumption at the business or for the consumer to take out from the business. Conditioning module 500 can also be a combination of any of these devices used to prepare nutritional substances for consumption by consumers.

Consumer module 600 collects information from the living entity which consumes the nutritional substance which has passed through the various modules from creation to consumption. The consumer can be a human being, but could also be an animal, such as pets, zoo animals and livestock, which are they themselves nutritional substances for other consumption chains. Consumers could also be plant life which consumes nutritional substances to grow.

Information module 100 receives and transmits information regarding a nutritional substance between each of the modules in the nutritional substance industry 10 including, the creation module 200, the preservation module 300, the transformation module 400, the conditioning module 500, and the consumer module 600. The nutritional substance information module 100 can be an interconnecting information transmission system which allows the transmission of information between various modules. Information module 100 contains a database, also referred to herein as a dynamic nutritional value database, where the information regarding the nutritional substance resides. Information module 100 can be connected to the other modules by a variety of communication systems, such as paper, computer networks, the internet and telecommunication systems, such as wireless telecommunication systems. In a system capable of receiving and processing real time consumer feedback and updates regarding changes in the nutritional, organoleptic, and/or aesthetic value of nutritional substances, or ΔN, consumers can even play a role in updating a dynamic nutritional value database with observed or measured information about the nutritional substances they have purchased and/or prepared for consumption, so that the information is available and useful to others in the nutritional substance supply system, such as through reports reflecting the consumer input or through modification of ΔN.

FIG. 2 is a graph showing the function of how a nutritional, organoleptic, or aesthetic value of a nutritional substance varies over the change in a condition of the nutritional substance. Plotted on the vertical axis of this graph can be either the nutritional value, organoleptic value, or even the aesthetic value of a nutritional substance. Plotted on the horizontal axis can be the change in condition of the nutritional substance over a variable such as time, temperature, location, and/or exposure to environmental conditions. This exposure to environmental conditions can include: exposure to air, including the air pressure and partial pressures of oxygen, carbon dioxide, water, or ozone; airborne chemicals, pollutants, allergens, dust, smoke, carcinogens, radioactive isotopes, or combustion byproducts; exposure to moisture; exposure to energy such as mechanical impact, mechanical vibration, irradiation, heat, or sunlight; or exposure to materials such as packaging. The function plotted as nutritional substance A could show a ΔN for milk, such as the degradation of a nutritional value of milk over time. Any point on this curve can be compared to another point to measure and/or describe the change in nutritional value, or the ΔN of nutritional substance A. The plot of the degradation in the same nutritional value of nutritional substance B, also milk, describes the change in nutritional value, or the ΔN of nutritional substance B, a nutritional substance which starts out with a higher nutritional value than nutritional substance A, but degrades over time more quickly than nutritional substance A.

In this example, where nutritional substance A and nutritional substance B are milk, this ΔN information regarding the nutritional substance degradation profile of each milk could be used by the consumer in the selection and/or consumption of the milk. If the consumer has this information at time zero when selecting a milk product for purchase, the consumer could consider when the consumer plans to consume the milk, whether that is on one occasion or multiple occasions. For example, if the consumer planned to consume the milk prior to the point when the curve represented by nutritional substance B crosses the curve represented by nutritional substance A, then the consumer should choose the milk represented by nutritional substance B because it has a higher nutritional value until it crosses the curve represented by nutritional substance A. However, if the consumer expects to consume at least some of the milk at a point in time after the time when the curve represented by nutritional substance B crosses the curve represented by nutritional substance A, then the consumer might choose to select the milk represented by the nutritional substance A, even though milk represented by nutritional substance A has a lower nutritional value than the milk represented by nutritional substance B at an earlier time. This change to a desired nutritional value in a nutritional substance over a change in a condition of the nutritional substance described in FIG. 2 can be measured and/or controlled throughout nutritional substance supply system 10 in FIG. 1. This example demonstrates how dynamically generated information regarding a ΔN of a nutritional substance, in this case a change in nutritional value of milk, can be used to understand a rate at which that nutritional value changes or degrades; when that nutritional value expires; and a residual nutritional value of the nutritional substance over a change in a condition of the nutritional substance, in this example a change in time. This ΔN information could further be used to determine a best consumption date for nutritional substance A and B, which could be different from each other depending upon the dynamically generated information generated for each.

In FIG. 1, Creation module 200 can dynamically encode nutritional substances to enable the tracking of changes in nutritional, organoleptic, and/or aesthetic value of the nutritional substance, or ΔN. This dynamic encoding, also referred to herein as a dynamic information identifier, can replace and/or complement existing nutritional substance marking systems such as barcodes, labels, and/or ink markings. This dynamic encoding, or dynamic information identifier, can be used to make nutritional substance information from creation module 200 available to information module 100 for use by preservation module 300, transformation module 400, conditioning module 500, and/or consumption module 600, which includes the ultimate consumer of the nutritional substance. One method of marking the nutritional substance with a dynamic information identifier by creation module 200, or any other module in nutritional supply system 10, could include an electronic tagging system, such as the tagging system manufactured by Kovio of San Jose, Calif., USA. Such thin film chips can be used not only for tracking nutritional substances, but can include components to measure attributes of nutritional substances, and record and transmit such information. Such information may be readable by a reader including a satellite-based system. Such a satellite-based nutritional substance information tracking system could comprise a network of satellites with coverage of some or all the surface of the earth, so as to allow the dynamic nutritional value database of information module 100 real time, or near real time updates about a ΔN of a particular nutritional substance.

Preservation module 300 includes packers and shippers of nutritional substances. The tracking of changes in nutritional, organoleptic, and/or aesthetic values, or a ΔN, during the preservation period within preservation module 300 allows for dynamic expiration dates for nutritional substances. For example, expiration dates for dairy products are currently based generally only on time using assumptions regarding minimal conditions at which dairy products are maintained. This extrapolated expiration date is based on a worst-case scenario for when the product becomes unsafe to consume during the preservation period. In reality, the degradation of dairy products may be significantly less than this worst-case. If preservation module 300 could measure or derive the actual degradation information such as ΔN, an actual expiration date, referred to herein as a dynamic expiration date, can be determined dynamically, and could be significantly later in time than an extrapolated expiration date. This would allow the nutritional substance supply system to dispose of fewer products due to expiration dates. This ability to dynamically generate expiration dates for nutritional substances is of particular significance when nutritional substances contain few or no preservatives. Such products are highly valued throughout nutritional substance supply system 10, including consumers who are willing to pay a premium for nutritional substances with few or no preservatives.

It should be noted that a dynamic expiration date need not be indicated numerically (i.e., as a numerical date) but could be indicated symbolically as by the use of colors—such as green, yellow and red employed on semaphores—or other designations. In those instances, the dynamic expiration date would not be interpreted literally but, rather, as a dynamically-determined advisory date. In practice a dynamic expiration date will be provided for at least one component of a single or multi-component nutritional substance. For multi-component nutritional substances, the dynamic expiration date could be interpreted as a “best” date for consumption for particular components.

By law, in many localities, food processors such as those in transformation module 400 are required to provide nutritional substance information regarding their products. Often, this information takes the form of a nutritional table applied to the packaging of the nutritional substance. Currently, the information in this nutritional table is based on averages or minimums for their typical product. Using the nutritional substance information from information module 100 provided by creation module 200, preservation module 300, and/or information from the transformation of the nutritional substance by transformation module 400, the food processor could include a dynamically generated nutritional value table, also referred to herein as a dynamic nutritional value table, for the actual nutritional substance being supplied. The information in such a dynamic nutritional value table could be used by conditioning module 500 in the preparation of the nutritional substance, and/or used by consumption module 600, so as to allow the ultimate consumer the ability to select the most desirable nutritional substance which meets their needs, and/or to track information regarding nutritional substances consumed.

Information about changes in nutritional, organoleptic, and/or aesthetic values of nutritional substances, or ΔN, is particularly useful in the conditioning module 500 of the present invention, as it allows knowing, or estimating, the pre-conditioning state of the nutritional, organoleptic, and/or aesthetic values of the nutritional substance, and allows for estimation of a ΔN associated with proposed conditioning parameters. The conditioning module 500 can therefore create conditioning parameters, such as by modifying existing or baseline conditioning parameters, to deliver desired nutritional, organoleptic, and/or aesthetic values after conditioning. The pre-conditioning state of the nutritional, organoleptic, and/or aesthetic value of a nutritional substance is not tracked or provided to the consumer by existing conditioners, nor is the ΔN expected from a proposed conditioning tracked or provided to the consumer either before or after conditioning. However, using information provided by information module 100 from creation module 200, preservation module 300, transformation module 400, and/or information measured or generated by conditioning module 500, conditioning module 500 could provide the consumer with the actual, and/or estimated change in nutritional, organoleptic, and/or aesthetic values of the nutritional substance, or ΔN. Further, consumer feedback and updates regarding observed or measured changes in the nutritional, organoleptic, and/or aesthetic value of nutritional substances, or ΔN, can play a role in updating a dynamic nutritional value database with information about the nutritional substances consumers have purchased and/or prepared for consumption, so that the information is available and useful to others in the nutritional substance supply system, such as through reports reflecting the consumer input or through modification of ΔN. Such information regarding the change to nutritional, organoleptic and/or aesthetic value of the nutritional substance, or ΔN, could be provided not only to the consumer, but could also be provided to information module 100 for use by creation module 200, preservation module 300, transformation module 400, so as to track, and possibly improve nutritional substances throughout the entire nutritional substance supply system 10.

The information regarding nutritional substances provided by information module 100 to consumption module 600 can replace or complement existing information sources such as recipe books, food databases like www.epicurious.com, and Epicurious apps. Through the use of specific information regarding a nutritional substance from information module 100, consumers can use consumption module 600 to select nutritional substances according to nutritional, organoleptic, and/or aesthetic values. This will further allow consumers to make informed decisions regarding nutritional substance additives, preservatives, genetic modifications, origins, traceability, and other nutritional substance attributes that may also be tracked through the information module 100. This information can be provided by consumption module 600 through personal computers, laptop computers, tablet computers, and/or smartphones. Software running on these devices can include dedicated computer programs, modules within general programs, and/or smartphone apps. An example of such a smartphone app regarding nutritional substances is the iOS ShopNoGMO from the Institute for Responsible Technology. This iPhone app allows consumers access to information regarding non-genetically modified organisms they may select. Additionally, consumption module 600 may provide information for the consumer to operate conditioning module 500 in such a manner as to optimize nutritional, organoleptic, and/or aesthetic values of a nutritional substance and/or component nutritional substances thereof, according to the consumer's needs or preference or according to target values established by the provider of the nutritional substance, such as the transformer, and/or minimize degradation of, preserve, or improve nutritional, organoleptic, and/or aesthetic value of a nutritional substance and/or component nutritional substances thereof.

Through the use of nutritional substance information available from information module 100 nutritional substance supply system 10 can track nutritional, organoleptic, and/or aesthetic value. Using this information, nutritional substances travelling through nutritional substance supply system 10 can be dynamically valued and priced according to nutritional, organoleptic, and/or aesthetic values. For example, nutritional substances with longer dynamic expiration dates (longer shelf life) may be more highly valued than nutritional substances with shorter expiration dates. Additionally, nutritional substances with higher nutritional, organoleptic, and/or aesthetic values may be more highly valued, not just by the consumer, but also by each entity within nutritional substance supply system 10. This is because each entity will want to start with a nutritional substance with higher nutritional, organoleptic, and/or aesthetic value before it performs its function and passes the nutritional substance along to the next entity. Therefore, both the starting nutritional, organoleptic, and/or aesthetic value and the ΔN associated with those values are important factors in determining or estimating an actual, or residual, nutritional, organoleptic, and/or aesthetic value of a nutritional substance, and accordingly are important factors in establishing dynamically valued and priced nutritional substances.

During the period of implementation of the present inventions, there will be nutritional substances being marketed including those benefiting from the tracking of dynamic nutritional information such as ΔN, also referred to herein as information-enabled nutritional substances, and nutritional substances which do not benefit from the tracking of dynamic nutritional information such as ΔN, which are not information enabled and are referred to herein as dumb nutritional substances. Information-enabled nutritional substances would be available in virtual internet marketplaces, as well as traditional marketplaces. Because of information provided by information-enabled nutritional substances, entities within the nutritional substance supply system 10, including consumers, would be able to review and select information-enabled nutritional substances for purchase. It should be expected that, initially, the information-enabled nutritional substances would enjoy a higher market value and price than dumb nutritional substances. However, as information-enabled nutritional substances become more the norm, the cost savings from less waste due to degradation of information-enabled nutritional substances could lead to their price actually becoming less than dumb nutritional substances.

For example, the producer of a ready-to-eat dinner would prefer to use corn of a high nutritional, organoleptic, and/or aesthetic value in the production of its product, the ready-to-eat dinner, so as to produce a premium product of high nutritional, organoleptic, and/or aesthetic value. Depending upon the levels of the nutritional, organoleptic, and/or aesthetic values, the ready-to-eat dinner producer may be able to charge a premium price and/or differentiate its product from that of other producers. When selecting the corn to be used in the ready-to-eat dinner, the producer will seek corn of high nutritional, organoleptic, and/or aesthetic value from preservation module 300 that meets its requirements for nutritional, organoleptic, and/or aesthetic value. The packager/shipper of preservation module 300 would also be able to charge a premium for corn which has high nutritional, organoleptic, and/or aesthetic values. And finally, the packager/shipper of preservation module 300 will select corn of high nutritional, organoleptic, and/or aesthetic value from the grower of creation module 200, who will also be able to charge a premium for corn of high nutritional, organoleptic, and/or aesthetic values.

The change to nutritional, organoleptic, and/or aesthetic value for a nutritional substance, or ΔN, tracked through nutritional substance supply system 10 through nutritional substance information from information module 100 can be preferably determined from measured information. However, some or all such nutritional substance ΔN information may be derived through measurements of environmental conditions of the nutritional substance as it travelled through nutritional substance supply system 10. Additionally, some or all of the nutritional substance ΔN information can be derived from ΔN data of other nutritional substances which have travelled through nutritional substance supply system 10. Nutritional substance ΔN information can also be derived from laboratory experiments performed on other nutritional substances, which may approximate conditions and/or processes to which the actual nutritional substance has been exposed. Further, consumer feedback and updates regarding observed or measured changes in the nutritional, organoleptic, and/or aesthetic value of nutritional substances can play a role in updating ΔN information.

For example, laboratory experiments can be performed on bananas to determine effect on or change in nutritional, organoleptic, and/or aesthetic value, or ΔN, for a variety of environmental conditions bananas may be exposed to during packaging and shipment in preservation module 300. Using this experimental data, tables and/or algorithms could be developed which would predict the level of change of nutritional, organoleptic, and/or aesthetic values, or ΔN, for a particular banana based upon information collected regarding the environmental conditions to which the banana was exposed during its time in preservation module 300. While the ultimate goal for nutritional substance supply system 10 would be the actual measurement of nutritional, organoleptic, and/or aesthetic values to determine ΔN, use of derived nutritional, organoleptic, and/or aesthetic values from experimental data to determine ΔN would allow improved logistics planning because it provides the ability to prospectively estimate changes to nutritional, organoleptic, and/or aesthetic values, or ΔN, and because it allows more accurate tracking of changes to nutritional, organoleptic, and/or aesthetic values, or ΔN, while technology and systems are put in place to allow actual measurement.

In an alternate embodiment reader 340 can also write to information storage module 330. In this embodiment, information regarding the container and/or nutritional substance 320 can be modified or added to information storage module 330 by the user or shipper.

FIG. 4 shows another embodiment of preservation module 300 wherein container 310 contains nutritional substance 320 as well as controller 350. Controller 350 is connected to external sensor 360 located either inside, on the surface of, or external to container 310 such that external sensor 360 can obtain information regarding the environment external to container 310. Controller 350 and exterior sensor 360 can take the form of electronic components such as a micro-controller and an electronic sensor. However, the controller-sensor combination may also be chemical or organic materials which perform the same function, such as a liquid crystal sensor/display.

When the shipper or user of container 310 desires information from external sensor 360 the shipper or user can use reader 340 to query the controller 350 as to the state of external sensor 360. In the electronic component embodiment, reader 340 could be a user interface device such as a computer which can be electronically connected to controller 350. If the controller-sensor combination is a liquid crystal sensor/display, the ready could be a human looking at the display.

In an additional embodiment, controller 350 can modify the operation of container 310 so as to modify the preservation capabilities of container 310. For example, if the exterior environment of container 310 would adversely affect the nutritional substance 320, container 310 could adjust the internal environment of container 310 to better preserve the nutritional substance. If nutritional substance needs to be kept within a certain temperature range to preserve its nutritional, organoleptic or aesthetic values or properties, and the external sensor 360 provides exterior temperature information to controller 350, controller 350 could modify container 310 so as to maintain nutritional substance 320 within the required temperature range.

Such information can be used to determine if the nutritional substance is no longer safe for consumption or has been degraded such that the nutritional substance is no longer in an optimal state. Additionally, the user of the nutritional substance could modify its transformation, conditioning, or consumption according to any changes that may have occurred because of the internal conditions of the container.

In an additional embodiment, controller 350 can modify the operation of container 310 so as modify the preservation capabilities of container 310. For example, if the internal environment of container 310 would adversely affect the nutritional substance 320, container 310 could adjust the internal environment of container 310 to better preserve the nutritional substance. Controller 350 can analyze the historic information from internal sensor 370, stored in information storage module 330 to determine any long-term internal environmental conditions. If nutritional substance needs to be kept within a certain temperature range to preserve its nutritional, organoleptic or aesthetic values or properties, and the internal sensor 370 provides internal temperature information to controller 350, controller 350 could modify container 310 so as to maintain nutritional substance 320 within the required temperature range.

Alternatively, nutritional substance sensor 380 or reader 340 can transmit information stored in or collected by nutritional substance sensor 380 to information module 100 and can further associate the transmitted information with the dynamic information identifier provided on the nutritional substance. A consumer or other member of the nutritional substance supply system would then be able to retrieve from information module 100 the information that was stored in or collected by nutritional substance sensor 380 by using the dynamic information identifier associated with the nutritional substance and provided on the nutritional substance. This would allow the shipper or user of container 310 to understand the condition of the nutritional substance during the time it is been preserved. Such information can be used to determine if the nutritional substance is no longer safe for consumption or has been degraded such that the nutritional substance is no longer in an optimal state. Additionally, the user of the nutritional substance could modify its transformation, conditioning, or consumption according to any changes that may have occurred because of the internal conditions of the container.

In an additional embodiment, controller 350 can modify the operation of container 310 so as modify the preservation capabilities of container 310. For example, if the interior environment of container 310 is adversely affecting the nutritional substance 320, container 310 could adjust the nutritional substance environment of container 310 to better preserve the nutritional substance. If nutritional substance needs to be kept within a certain temperature range to preserve its nutritional, organoleptic or aesthetic values or properties, and the nutritional substance sensor 380 provides nutritional substance temperature information to controller 350, controller 350 could modify container 310 so as to maintain nutritional substance 320 within the required temperature range.

Information module 100 can connect to controller 350 directly, or using reader 340, to retrieve and preserve information stored in information storage module 330, and can further associate that information with the dynamic information identifier provided on the nutritional substance. Alternatively, controller 350 or reader 340 can transmit information stored in information storage module 330 to information module 100 and can further associate the transmitted information with the dynamic information identifier provided on the nutritional substance. A consumer or other member of the nutritional substance supply system would then be able to retrieve from information module 100 the information that was stored in information storage module 330 by using the dynamic information identifier associated with the nutritional substance and provided on the nutritional substance. This would allow the shipper or user of container 310 to understand the condition of nutritional substance 320 during the time it has been preserved. Such information can be used to determine if the nutritional substance is no longer safe for consumption or has been degraded such that the nutritional substance is no longer in an optimal state. Additionally, the user of the nutritional substance could modify its transformation, conditioning, or consumption according to any changes that may have occurred during storage in the container.

In an additional embodiment, controller 350 can modify the operation of container 310 so as modify the preservation capabilities of container 310. For example, if the nutritional substance 320 is being adversely affected, controller 350 could adjust the container 310 to better preserve the nutritional substance. Controller 350 can analyze the historic information from nutritional substance sensor 380 stored in information storage module 330 to determine any long-term nutritional substance condition trends that may need modification. If the nutritional substance sensor 380 provides nutritional substance information to controller 350 indicating a trend that needs modification, controller 350 could modify container 310 such that the trend of nutritional substance condition is more desirable.

FIG. 13 shows another embodiment of preservation module 300. Within container 310 is nutritional substance 320, nutritional substance sensor 380, internal sensor 370, information storage module 330, and controller 350. External sensor 360 is located outside or on the surface of container 310. In operation, controller 350 receives information from nutritional substance sensor 380, internal sensor 370, and external sensor 360. Additionally, controller 350 can store the information received from the three sensors in information storage module 330. Controller 350 can retrieve such stored information and transmit it to reader 340. Reader 340 can also transmit instructions to controller 350.

Information in the information storage module 330 includes information regarding the condition of the nutritional substance from nutritional substance sensor 380, information regarding the environment internal to container 310 from internal sensor 370, and information regarding the environment external to container 310 from external sensor 360. Further, information in the information storage module 330 can include creation or origin information from the creation of the nutritional substance 320 and/or prior preservation or transformation information and other historic information regarding the nutritional substance 320. Information in the information storage module 330 might additionally include identification information, such as a dynamic information identifier provided on the nutritional substance, which is associated with source and origin information or information regarding prior transformation or prior storage or prior transport of the nutritional substance 320 and other historic information preserved in information module 100. A shipper, or user, of container 310 can operatively connect to information storage module 330 using reader 340 to retrieve information stored in information storage module 330. Information module 100 can connect to controller 350 directly, or using reader 340, to retrieve and preserve information stored in information storage module 330, and can further associate that information with the dynamic information identifier provided on the nutritional substance. Alternatively, controller 350 or reader 340 can transmit information stored in information storage module 330 to information module 100 and can further associate the transmitted information with the dynamic information identifier provided on the nutritional substance. A consumer or other member of the nutritional substance supply system would then be able to retrieve from information module 100 the information that was stored in information storage module 330 by using the dynamic information identifier associated with the nutritional substance and provided on the nutritional substance. This would allow the shipper or user of container 310 to understand the condition of nutritional substance 320 during the time it has been preserved, as well as the environment internal and external to container 310 during the preservation period. Such information can be used to determine if the nutritional substance is no longer safe for consumption or has been degraded such that the nutritional substance is no longer in an optimal state. Additionally, the user of the nutritional substance could modify its transformation, conditioning, or consumption according to any changes that may have occurred during storage in the container.

In an additional embodiment, controller 350 can modify the operation of container 310 so as modify the preservation capabilities of container 310. For example, if the nutritional substance 320 is being adversely affected, controller 350 could adjust the container 310 to better preserve the nutritional substance. Controller 350 can analyze the historic information stored in information storage module 330 regarding nutritional substance sensor 380, internal sensor 370, and external sensor 360 to determine any long-term nutritional substance condition trends, internal environment trends, and external environment trends that may need modification. If the nutritional substance sensor 380 or the internal sensor 370 or the external sensor 360 provide information to controller 350 indicating a trend that requires modification of container 310, controller 350 could modify container 310 such that the trend is offset or compensated for.

As an example, nutritional substance 320 could be bananas being shipped to a distribution warehouse. Bananas are in container 310 which is capable of controlling its internal temperature, humidity, and the level of certain gasses within the container. Creation information as to the bananas is placed in information storage module 330 prior to shipment. During shipment, external sensor 360 measures the temperature and humidity outside container 310. This information is stored by controller 350 in information storage module 330. Controller 350 also receives information on the internal environment within container 310 from internal sensor 370 and stores this information in information storage module 330. This information includes the internal temperature, humidity, and certain gas levels within container 310. Finally, nutritional substance sensor 380, which is attached to the surface of the bananas, provides information as to the state of the bananas to controller 350. This information could include surface temperature, surface humidity, gasses being emitted, and surface chemicals. At any time during its shipment and delivery to the distribution warehouse, reader 340 can be used to retrieve both current information and historic information stored within information storage module 330. Alternatively, at any time during its shipment and delivery to the distribution warehouse, reader 340 or controller 350 can transmit both current information and historic information stored within information storage module 330 to information module 100 so that the information is available for remote retrieval from information module 100.

During shipment, container 310 modifies its internal conditions according to instructions provided by controller 350. Controller 350 contains instructions as to how to preserve, and possibly ripen, the bananas using information stored in information storage module 330 about the creation of the bananas, as well as historical information received from the three sensors, as well as current information being received from the three sensors. In this manner, preservation module 300 can preserve and optimize nutritional, organoleptic or aesthetic values or properties or attributes of the bananas while they are being shipped and stored.

It will be understood that subsets of the embodiment described herein can operate to achieve the goals stated herein. In one embodiment, nutritional substance sensor 380, internal sensor 370, external sensor 360, information storage module 330, controller 350, reader 340, and parts of container 310 are each electrical or electromechanical devices which perform each of the indicated functions. However, it is possible for some or all of these functions to be done using chemical and/or organic compounds. For example, a specifically designed plastic wrap for bananas can sense the exterior conditions of the package, the interior conditions of the package, and control gas flow through its surface so as to preserve and ripen the bananas.

Examples

Nutritional substances are commonly preserved utilizing various freezing techniques. While freezing is well recognized as an effective method of preservation, it can cause a degradation of nutritional, organoleptic, or aesthetic value, a negative ΔN, for the nutritional substance being frozen. Additional ΔN can occur during subsequent storage and transfer of the nutritional substance on its path from being packaged and frozen to being consumed. These additional ΔNs can occur as a result of: frozen storage; transfer to a distributor or retailer; and storage by the distributor or retailer.

FIG. 14 provides a schematic showing exemplary steps that may occur to a frozen nutritional substance before it is sold to a consumer. FIG. 14 further shows that the nutritional substance has a baseline nutritional, organoleptic, or aesthetic value (N_BASELINE), then experiences a change in the nutritional, organoleptic, or aesthetic value (ΔN) at each subsequent step before being sold to a consumer.

Some examples will now be provided of how a preservation system for nutritional substances according to the present invention provides beneficial: source and origin information for the nutritional substance; information regarding a change in nutritional, organoleptic, or aesthetic value of the nutritional substance; and information as to a current nutritional, organoleptic, or aesthetic state of the nutritional substance.

In one example, the raw material is freshly caught farm raised salmon. Referring to FIG. 14, when the salmon is first caught it is at its baseline nutritional, organoleptic, and aesthetic value, N_BASELINE. Transformation of the salmon involves cleaning and cutting the salmon into steaks. From the time the salmon is caught and during the time the salmon is being cleaned and cut, it is advantageous to maintain the salmon at low temperatures, but also to avoid uncontrolled freezing of the salmon. Based on the conditions and amount of time that the salmon is maintained from the time it is caught and during the time it is being cleaned and cut, there will be changes, likely a degradation, in nutritional, organoleptic, or aesthetic value. These changes are shown as ΔN₁in FIG. 14. The nutritional, organoleptic, or aesthetic state of the salmon following preparation and transformation would be equal to the sum of its baseline nutritional, organoleptic, or aesthetic value and the change in said nutritional, organoleptic, or aesthetic value that occurred during transformation. In other words, the nutritional, organoleptic, or aesthetic value following transformation equals N_BASELINE+ΔN₁.

The cleaned and cut salmon steaks are then packaged and frozen. Based on the type of packaging used and the freezing process applied, there will be changes, likely a degradation, in nutritional, organoleptic, or aesthetic value. These changes are shown as ΔN₂in FIG. 14. The nutritional, organoleptic, or aesthetic state of the salmon following packaging and freezing would be equal to the sum of its baseline nutritional, organoleptic, or aesthetic value and the change in said nutritional, organoleptic, or aesthetic value that occurred during transformation and the change in said nutritional, organoleptic, or aesthetic value that occurred during packaging and freezing. In other words, the nutritional, organoleptic, or aesthetic value following packaging and freezing equals N_BASELINE+ΔN₁+ΔN₂.

The packaged and frozen salmon steaks are then put into frozen storage. Based on the type of packaging used and the time and conditions of frozen storage, there will be changes, likely a degradation, in nutritional, organoleptic, or aesthetic value. These changes are shown as ΔN₃in FIG. 14. The nutritional, organoleptic, or aesthetic state of the salmon following frozen storage would be equal to the sum of its baseline nutritional, organoleptic, or aesthetic value and the change in said nutritional, organoleptic, or aesthetic value that occurred during transformation and the change in said nutritional, organoleptic, or aesthetic value that occurred during packaging and freezing and the change in said nutritional, organoleptic, or aesthetic value that occurred during frozen storage. In other words, the nutritional, organoleptic, or aesthetic value following frozen storage equals N_BASELINE+ΔN₁+ΔN₂+ΔN₃.

The packaged and frozen salmon steaks are eventually transferred to a distributor or retailer. Based on the time and conditions during transfer, there will be changes, likely a degradation, in nutritional, organoleptic, or aesthetic value. These changes are shown as ΔN₄in FIG. 14. The nutritional, organoleptic, or aesthetic state of the salmon following transfer to a distributor or retailer would be equal to the sum of its baseline nutritional, organoleptic, or aesthetic value and the change in said nutritional, organoleptic, or aesthetic value that occurred during transformation and the change in said nutritional, organoleptic, or aesthetic value that occurred during packaging and freezing and the change in said nutritional, organoleptic, or aesthetic value that occurred during frozen storage and the change in said nutritional, organoleptic, or aesthetic value that occurred during transfer to the distributor or retailer. In other words, the nutritional, organoleptic, or aesthetic value following transfer to distributor equals N_BASELINE+ΔN₁+ΔN₂+ΔN₃+ΔN₄.

The packaged and frozen salmon steaks are then stored by the distributor or retailer, awaiting sale to a consumer. Based on the time and conditions of storage by the distributor or retailer, there will be changes, likely a degradation, in nutritional, organoleptic, or aesthetic value. These changes are shown as ΔN₅in FIG. 14. The nutritional, organoleptic, or aesthetic state of the salmon following storage by a distributor or retailer would be equal to the sum of its baseline nutritional, organoleptic, or aesthetic value and the change in said nutritional, organoleptic, or aesthetic value that occurred during transformation and the change in said nutritional, organoleptic, or aesthetic value that occurred during packaging and freezing and the change in said nutritional, organoleptic, or aesthetic value that occurred during frozen storage and the change in said nutritional, organoleptic, or aesthetic value that occurred during transfer to the distributor or retailer and the change in said nutritional, organoleptic, or aesthetic value that occurred during storage by the distributor or retailer. In other words, the nutritional, organoleptic, or aesthetic value following storage by a distributor or retailer and upon sale to a consumer equals N_BASELINE+ΔN₁+ΔN₂+ΔN₃+ΔN₄+ΔN₅.

For traditional methods of freezing, it is well understood that the quality of frozen nutritional substances is highly dependent on the rate at which it is frozen. Generally, rapid freezing results in higher quality frozen nutritional substances as compared to slow freezing. When freezing is rapid, there are more locations within the nutritional substance where nucleation occurs, that is, where ice crystallization begins. In contrast, when freezing is slow, there are relatively few nucleation sites resulting in larger ice crystals. It is known that these larger ice crystals can cause mechanical damage to cell walls and can further result in cell dehydration.

Examples of common traditional methods used for freezing nutritional substances include air-blast freezers, plate freezers, and liquid nitrogen freezers. These methods of freezing nutritional substances provide various benefits and advantages depending on the nutritional substance being frozen and upon other factors such as production rate, flexibility, equipment cost, and cost to operate. These methods of freezing nutritional substances can further be differentiated by the respective rates of freezing that they can deliver, which as previously discussed, can have a significant impact on the quality of the nutritional substance.

Air-blast freezers are among the oldest and most commonly used types of freezing equipment. They offer good temperature stability and versatility for many types of products. Air is generally used as the freezing medium and can be still air or forced air. The basic process involves placing nutritional substances in freezing rooms called sharp freezers. Still air freezers are the most economical method of freezing and provide the added advantage of a constant temperature during frozen storage. However, still air freezers are the slowest method of freezing due to the low surface heat transfer coefficient of circulating air inside the room.

Contact freezing can be a more efficient method of freezing in terms of heat transfer mechanism. The most common type of contact freezer is the plate freezer. In this case, the product is pressed between hallow metal plates, either horizontally or vertically, with a refrigerant circulating inside the plates. Pressure is applied for good contact. This type of freezing system is only limited to regular-shaped materials like patties or block-shaped packaged products, and is considerably faster than air-blast freezing in these situations.

Liquid nitrogen freezing, also known as flash freezing, is still more rapid than contact freezing methods such as with plate freezers. The refrigerant is liquid Nitrogen, with a boiling temperature of −196° C. at atmospheric pressure, and is sprayed into the freezer, evaporating upon leaving the spray nozzles and upon contact with the nutritional substance. These systems can provide high heat transfer efficiency, but consume Nitrogen in the range of 1.2-kg Nitrogen per 1-kg of nutritional substance. Typical nutritional substances frozen in this type of system include fish fillets.

A non-traditional freezing system that shows great promise for nutritional substances is known as a Cells Alive System, or CAS, developed by ABI. The technology does not depend on rapid rates of freezing to minimize damage caused by ice crystals, yet can deliver results even better than rapid freezing such as liquid Nitrogen freezing, that is with little to no degradation of nutritional, organoleptic, or aesthetic value. CAS technology uses an oscillating electrical field to cause water molecules within the nutritional substance to spin, stopping them from clustering and forming ice crystals that damage cell walls. Additionally, the spinning motion of the water molecules artificially lowers the freezing point of the water within the nutritional substance to approximately −7° C. Once the nutritional substance reaches this temperature, the oscillating electrical field is turned off and the water freezes almost instantaneously from the inside out, causing minimal or no cell damage. The natural life form of the cells of a CAS frozen nutritional substance is retained, without the physical damage to the cell wall and nucleus that results from ice crystal growth during traditional outside-to-inside freezing methods.

While CAS freezing has found selective application for preserving nutritional substances, the focus has been on organoleptic and aesthetic characteristics such as taste, texture, and appearance. The present invention can not only track, preserve, and communicate the values associated with these characteristics and changes in the values associated with these characteristics, it can additionally track, preserve, and communicate the nutritional value and changes in the nutritional value of a nutritional substance. This will be of great value to a consumer, who can now see the nutritional benefit associated with nutritional substances frozen by CAS methods. It will also be of great value to those offering nutritional substances frozen by CAS methods, as tracking and communicating a degradation in nutritional value close to, or equal to, zero will demonstrate that the nutritional substance offers similar or equal nutritional value as compared to freshly caught, freshly slaughtered, or freshly harvested nutritional substances.

Referring to FIG. 14, ΔN₂represents a change in nutritional, organoleptic, or aesthetic value of the nutritional substance, in this case a change resulting from packaging and freezing of the salmon steaks. Improvement of a nutritional, organoleptic, or aesthetic value would be represented by a positive value for ΔN₂. Maintenance of a nutritional, organoleptic, or aesthetic value would be represented by a zero value for ΔN₂. Degradation of a nutritional, organoleptic, or aesthetic value would be represented by a negative value for ΔN₂. It is understood that while all methods of freezing nutritional substances are intended to minimize degradation of nutritional, organoleptic, or aesthetic value, traditional outside-to-inside freezing methods such as air-blast freezing, contact freezing, and flash freezing are associated with various degrees of cell disruption and accordingly various degrees of nutritional substance ΔN or degradation, while CAS freezing methods can offer little to no cell disruption and accordingly little to no nutritional substance ΔN or degradation.

For the purpose of the following example it is understood that the amount of degradation to be expected from air-blast freezing is greater than the amount of degradation to be expected from contact freezing which is greater than the amount of degradation to be expected from liquid Nitrogen freezing which is greater than the amount of degradation to be expected from CAS freezing. Because degradation is represented by a negative number, the relationship can be described as: ΔN₂air-blast freezing <ΔN₂contact freezing <ΔN₂liquid Nitrogen freezing <ΔN₂CAS freezing ≦0. With this context, an example is offered of a preservation system according to the present invention. In this example, a transformer of the salmon steaks provides four varieties of frozen salmon steaks based upon nutritional, organoleptic, or aesthetic values of the product. The products are marketed as: economy; standard; premium; and ultra-premium.

The economy salmon steaks have been packaged and frozen by air-blast freezing, which is known to cause significant degradation, but is economical for the transformer. The standard salmon steaks have been packaged and frozen by contact freezing, such as in a plate freezer, which is known to cause degradation, but less than air-blast freezing. The premium salmon steaks have been packaged and frozen by liquid Nitrogen freezing, also known as flash freezing, which is known to cause less degradation than contact freezing. The ultra-premium salmon steaks have been packaged and frozen by CAS freezing, which is known to cause little to no degradation, which is less than liquid Nitrogen freezing.

The transformer stores its economy and standard products at −18° C., and stores its premium and ultra-premium products at −35° C. It is known that degradation of nutritional, organoleptic, or aesthetic value during frozen storage will be greater at storage temperatures of −18° C. compared to degradation of nutritional, organoleptic, or aesthetic value during frozen storage at −35° C. Because degradation is represented by a negative number, the relationship can be described as: ΔN₃frozen storage at −18° C.<ΔN₃frozen storage at −35° C.

Further, the transformer transfers its economy and standard products to distributors and retailers at −18° C., and transfers its premium and ultra-premium products to distributors and retailers at −35° C. Because degradation is represented by a negative number, the relationship can be described as: ΔN₄transfer at −18° C.<ΔN₄transfer at −35° C.

Still further, the transformer requires its distributors or retailers to store the economy, standard, and premium products at −18° C., but requires its distributors or retailers to store the ultra-premium product at −35° C. Because degradation is represented by a negative number, the relationship can be described as: ΔN₅storage at −18° C.<ΔN₄storage at −35° C.

The nutritional, organoleptic, or aesthetic value of any of these four salmon steak products from the transformer can be expressed as the sum of its baseline nutritional, organoleptic, or aesthetic value after each step it goes through on its journey through the nutritional substance supply system. After transformation, the nutritional, organoleptic, or aesthetic value of the economy salmon steak=the nutritional, organoleptic, or aesthetic value of the standard salmon steak=the nutritional, organoleptic, or aesthetic value of the premium salmon steak=the nutritional, organoleptic, or aesthetic value of the ultra-premium salmon steak=N_BASELINE+ΔN₁.

The consumer, or any other constituent in the nutritional substance supply system, can utilize reference information provided on the nutritional substance package by the transformer in the form of a dynamic information identifier. The dynamic information identifier allows retrieval of source and origin information as well as information regarding changes in nutritional, organoleptic, or aesthetic values of the nutritional substance from a nutritional substance information system, such as from a dynamic nutritional value database.

An example of how this benefits a distributor or retailer of the premium salmon steaks, as compared to products provided without a dynamic information identifier will now be discussed. Upon receiving the premium salmon steaks from transfer, the distributor or retailer can verify source and origin information regarding the premium salmon steaks using the dynamic information identifier provided with the nutritional substance to retrieve the source and origin information from a nutritional substance information system. Further, the distributor or retailer can verify that the nutritional, organoleptic, or aesthetic values expected of this type of product have actually been maintained using the dynamic information identifier provided with the nutritional substance to retrieve information regarding actual ΔN associated with the premium salmon steaks from a nutritional substance information system. In this way, the distributor or retailer has access to information regarding ΔN and a current state of nutritional, organoleptic, or aesthetic value of the premium salmon steaks. The nutritional substance information system can communicate the ΔN at transfer to distributor, which would equal ΔN₁+ΔN₂liquid Nitrogen freezing+ΔN₃frozen storage at −35° C.+ΔN₄transfer at −35° C. The nutritional substance information system can further communicate a current nutritional, organoleptic, or aesthetic value of the premium salmon steaks at transfer to distributor, which would equal N_BASELINE+ΔN₁+ΔN₂liquid Nitrogen freezing+ΔN₃frozen storage at −35° C.+ΔN₄transfer at −35° C. If the product had been received without a dynamic information identifier, the distributor or retailer would have access to very limited information regarding the product, and no information regarding ΔN or the current state of nutritional, organoleptic, or aesthetic value of the product.

An example of how this benefits a consumer shopping for premium or ultra-premium salmon steaks provided with a dynamic information identifier, as compared to products provided without a dynamic information identifier, will now be discussed. At the supermarket the consumer can verify source and origin information regarding the premium salmon steaks using the dynamic information identifier provided with the nutritional substance to retrieve the source and origin information from a nutritional substance information system. Preferably, this is accomplished with the consumer's smart phone. Further, the consumer can verify that the nutritional, organoleptic, or aesthetic values expected of this type of product have actually been maintained using the dynamic information identifier provided with the nutritional substance to retrieve information regarding actual ΔN associated with the premium salmon steaks from a nutritional substance information system. In this way, the consumer has access to information regarding ΔN and a current state of nutritional, organoleptic, or aesthetic value of the premium salmon steaks. The nutritional substance information system can communicate the current ΔN at the time of the consumer's query, which would equal ΔN₁+ΔN₂liquid Nitrogen freezing+ΔN₃frozen storage at −35° C.+ΔN₄transfer at −35° C.+ΔN₅storage at −18° C. The nutritional substance information system can further communicate a current nutritional, organoleptic, or aesthetic value of the premium salmon steaks at the time of the consumer's query, which would equal N_BASELINE+ΔN₁ΔN₂liquid Nitrogen freezing+ΔN₃frozen storage at −35° C.+ΔN₄transfer at −35° C.+ΔN₅storage at −18° C. Now the consumer can verify source and origin information regarding the ultra-premium salmon steaks using the dynamic information identifier provided with the nutritional substance to retrieve the source and origin information from a nutritional substance information system. Preferably, this is accomplished with the consumer's smart phone. Further, the consumer can verify that the nutritional, organoleptic, or aesthetic values expected of this type of product have actually been maintained using the dynamic information identifier provided with the nutritional substance to retrieve information regarding actual ΔN associated with the ultra-premium salmon steaks from a nutritional substance information system. In this way, the consumer has access to information regarding ΔN and a current state of nutritional, organoleptic, or aesthetic value of the ultra-premium salmon steaks. The nutritional substance information system can communicate the current ΔN at the time of the consumer's query, which would equal ΔN₁+ΔN₂CAS freezing+ΔN₃frozen storage at −35° C.+ΔN₄transfer at −35° C.+ΔN₅storage at −35° C. The nutritional substance information system can further communicate a current nutritional, organoleptic, or aesthetic value of the ultra-premium salmon steaks at the time of the consumer's query, which would equal N_BASELINE+ΔN₁ΔN₂CAS freezing+ΔN₃frozen storage at −35° C.+ΔN₄transfer at −35° C.+ΔN₅storage at −35° C. If the product had been offered for sale without a dynamic information identifier, the consumer would have access to very limited information regarding the product, and no information regarding ΔN or the current state of nutritional, organoleptic, or aesthetic value of the product. Because these products were provided with dynamic information identifiers, the consumer can now make an informed comparison of the two products and an informed purchasing decision.
