In fact, in many of the preferred embodiments, these advantages are optimized to an extent that is considerably higher than heretofore achieved in prior, known systems and methods for preserving all-natural beverages.

BRIEF DESCRIPTION OF THE DRAWINGS

The above-mentioned features and steps of the invention and the manner of attaining them will become apparent, and the invention itself will be best understood by reference to the following description of the embodiments of the invention in conjunction with the accompanying drawing and in which:

FIG. 1 is a schematic illustration of the method of preserving all-natural beverages such as fruit juice by using alcohol and high-pressure processing (HPP), according to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

Consumers are drinking more all-natural beverages such as organic fruit juices because these juices taste better, have a just-squeezed appearance and are nutritional without using any preservatives or additives. However, in order to mass produce such all-natural beverages, the fruit juice cannot be heat-treated since the heat treatment will adversely affect the taste and the nutritional benefits of the organic fruit juice. In order to address this problem, it is known to use high-pressure processing (HPP) in the processing of food products such as beverages.

During HPP, the beverage is subjected to very high pressures (up to 100,000 psi). These high pressures inactivate the pathogens or other microorganisms that may be found in the beverages. It has also been found that these high pressures do not adversely affect the taste, texture, color and nutritional benefits of the beverages. While these prior, known HPP systems and methods are generally satisfactory in processing beverages, the processed beverages are not shelf stable and, therefore, must be refrigerated. Consequently, it is desirable to create a system and method that is capable of preserving of all-natural beverages such as fruit juice by using alcohol and high-pressure processing (HPP) in order to remove any pathogens from the all-natural beverage and to provide a stable product that has a long shelf life without the need for refrigeration and without adversely affecting the taste and the nutritional benefits of the all-natural beverage.

Referring now to FIG. 1, there is illustrated a method 100 of preserving of all-natural beverages such as fruit juice by using alcohol and high-pressure processing (HPP). As will be explained hereinafter in greater detail, the method 100 of processing beverages is capable of preserving all-natural beverages such as fresh fruit juice or frozen fruit juice that has been thawed by using alcohol and high-pressure processing (HPP) in order to remove any pathogens from the all-natural beverage and to provide a stable product that has a long shelf life without the need for refrigeration and without adversely affecting the taste and the nutritional benefits of the all-natural beverage.

With respect to the presently disclosed invention, the following should be considered relative to the organic, all-natural juice component of the system and method. It is to be understood that non-organic fruit juice could also be used. That is, the all-natural juice (whether it is organic or non-organic) is preferably prepared and packaged according to conventional all-natural juice production techniques. Also, the all-natural juice is inspected by the beverage packager prior to and after the packaging of the all-natural juice, according to well-known processes and procedures. After the all-natural juice has been conventionally prepared and packaged, the packaged all-natural juice is then ready to be processed according to the present invention, as will be described in greater detail below.

Also, the following should be considered relative to the alcohol component of the system and method. That is, the alcohol is preferably any suitable distilled alcohol (such as alcohols (including ethanol (or ethyl alcohol)) distilled from wine or other fermented fruit, a plant juice or a starchy material such as or potatoes), beer or wine that are suitable for human consumption. It is to be understood that cannabidiol (CBD) can also be added as another component of the system and method. It is to be further understood that CBD may be used in addition to the alcohol component since the alcohol is needed to ensure ambient temperature stability of the processed product.

Method of Processing the all-Natural Beverage Using Alcohol and High-Pressure Processing (HPP)

The following example is provided merely for illustrating the present invention and is not to be intended as limiting the scope of protection of the appended claims.

Example 1

1.) Composition

An all-natural beverage such as fruit juice has been has been formulated with the following composition:

• • a.) Types of all-natural juices or juice blends include, but are not limited to: lime juice, lemon juice, orange juice, other types of citrus juices, apple juice, grape juice, cranberry juice, tomato juice, other types of fruit juices, and blends of any of these juices.
  • b.) Batch size of all-natural beverage such as fruit juice could be between about 100 and 1,000 gallons;
    • i. Preferably, the batch size will be between about 500 and 1,000 gallons of all-natural beverage; and
  • c.) The alcohol range level must be at least 2% to 20% of the total volume of the batch size
    • i. Preferably, the alcohol range level will be between about 5%-16% based on comparable alcohol-infused drinks.2.) Method 100 of FIG. 1)

The following steps were carried out:

Step 110—Receive Raw Materials

The raw materials are received from the raw material producers at the processing plant. In particular, the raw materials include, but are not limited to, the all-natural beverage such as fruit juice and the alcohol such any suitable distilled alcohol (such as alcohols distilled from wine or other fermented fruit, a plant juice or a starchy material such as or potatoes), beer or wine that are suitable for human consumption. It is to be understood that the producers of the raw materials must ensure that the raw materials do not contain any allergens. It is to be further understood that the raw materials should be conventionally inspected when received by the personnel at the processing plant to ensure that the raw materials comply with the desired raw material specifications and food safety standards.

Step 120—Cold Storage of Raw Materials

After the raw materials have been received and inspected by the personnel at the processing plant, the raw materials are stored in cold storage. In particular, the raw materials are conventionally stored in a refrigerated warehouse (at a temperature of 40° F. or less) that is continuously monitored to ensure product safety. Furthermore, the raw materials are placed on conventional storage racks in sealed, unopened containers so that the presence of allergens into the raw materials is substantially reduced or eliminated. It is to be understood that any raw material container that is found to be damaged or leaking during storage will be inspected to determine if the raw material contained within the damaged or leaking container is safe to be further processed. If the raw material is not safe to be further processed, the damaged raw material is then properly disposed.

Step 130—Thawing of Ingredients

While some of the raw materials may be transported to the processing plant as chilled beverages, other raw materials such as all-natural fruit juice may be frozen by the beverage producer in order to be able to properly transport the beverage from its processing location to a further processing plant. In particular, all-natural fruit juice that is processed overseas may need to be frozen so that the all-natural fruit juice will not spoil and will retain its fresh, just-squeezed appearance, flavor, texture and nutritional benefits.

If the raw material does arrive at the processing plant in a frozen state, the frozen raw materials are also conventionally stored in the refrigerated warehouse (at a temperature of 40° F. or less) that is continuously monitored to ensure product safety. Furthermore, the raw materials are placed on conventional storage racks in sealed, unopened containers so that frozen raw materials can properly thaw out and so that the presence of allergens into the raw materials is substantially reduced or eliminated. It is to be understood that any frozen, raw material container that is found to be damaged or leaking during storage will be inspected to determine if the frozen or thawed, raw material contained within the damaged or leaking container is safe to be further processed. If the raw material is not safe to be further processed, the damaged raw material is then properly disposed.

Step 140—Blending of Ingredients

During this step, the all-natural beverage such as fruit juice and alcohol such as grain alcohol or other similar distilled alcohols that are suitable for human consumption are combined together in batches in a conventional, industrial batch mixer (not shown) for mixing large quantities of beverage compositions. In particular, after the batch mixer has been conventionally cleaned and sanitized, the all-natural beverage is conventionally introduced into the batch mixer. It is to be understood that the all-natural beverage passes through a conventional containment screen (not shown) in order to prevent any foreign material from entering into the batch mixer. It is to be further understood that the pH of the all-natural beverage is conventionally tested to ensure that the pH is at or below 4.6 in order to reduce the likelihood of any pathogen or other microorganism growth in the all-natural beverage. Also, the alcohol content of the all-natural beverage is conventionally measured.

After the all-natural beverage has been introduced into the batch mixer, the alcohol is conventionally introduced into the batch mixer. In particular, the alcohol passes through the conventional containment screen (not shown) in order to prevent any foreign material from entering into the batch mixer. It is to be further understood that the alcohol volume (in terms of percentage of alcohol to the total volume of liquid in the batch mixer) is measured. In particular, the alcohol percentage should be 2-20% by volume with the preferred alcohol percentage range being 6-15% by volume. It is to be further understood that the all-natural beverage and alcohol composition must have a final pH (after high-pressure processing) that is at or below 4.6 in order to reduce the likelihood of any pathogen or other microorganism growth in the all-natural beverage and alcohol composition.

A unique aspect of the present invention is the addition of the alcohol component to the all-natural beverage and alcohol composition. As discussed above, the use of HPP to process beverages is well known. However, as discussed above, it has been found that beverages subjected to HPP typically are not shelf stable and, therefore, must be refrigerated. The addition of alcohol in an alcohol percentage range of 5-20% by volume has been found by the inventors of the present invention to eliminate the need to refrigerate the processed product. This allows the processed product of the present invention to be shipped anywhere in the world without the need for refrigeration. Furthermore, the addition of the alcohol will also aid in the reduction of any pathogens or other harmful microorganisms originally contained within the all-natural beverage.

Once the proper amounts of all-natural beverage and alcohol have been introduced into the batch mixer, the batch mixer then conventionally mixes the materials for approximately 3-7 minutes so that the all-natural beverage and alcohol components have been property and evenly blended.

Step 150—Straining of Ingredients

After the all-natural beverage and alcohol have been properly and evenly blended, the all-natural beverage and alcohol composition is conventionally strained. In particular, the blended composition of all-natural beverage and alcohol are strained through a conventional containment screen (not shown) to ensure that no contaminants or other foreign materials (such as glass, plastic, rocks, etc.) are sent to the bottling/capping area. Furthermore, the blended composition of all-natural beverage and alcohol is conventionally, visually inspected to ensure that no contaminants have passed through the containment screen.

Step 160—Bottling/Capping of Containers

Once the all-natural beverage and alcohol are conventionally strained, the strained all-natural beverage and alcohol are then conventionally bottled/capped. In particular, any suitable HPP-compatible beverage containers such as food grade polyethylene terephthalate (PET) containers are filled with the all-natural beverage and alcohol composition. It is to be understood that prior to filling the containers with the composition of all-natural beverage and alcohol, the food grade containers and the container caps (if used) are conventionally inspected to ensure that the containers and caps do not contain any contaminants. Also, the food grade containers and the caps (if used) are then conventionally cleaned and sterilized prior to being filled with the all-natural beverage and alcohol composition. After the food grade containers have been properly filled with the desired amount of all-natural beverage and alcohol composition, the containers are conventionally sealed or capped so that no pathogens can be later introduced into the packaged all-natural beverage and alcohol composition. It is to be understood that the containers can be in the form of bottles, stand-up pouches, large bulk bags or the like.

Step 170—Labeling of Filled Containers

After the food grade containers have been properly filled with the desired amount of all-natural beverage and alcohol composition and the containers have been conventionally sealed or capped, the desired labeling is conventionally applied to the filled containers, if needed. If the containers are already printed with the labeling such as individual, stand-up pouches which a pre-printed with labels, there may not be a need to apply any further labels after the pouches have been filled. It is to be understood that the all-natural beverage and alcohol composition contained within the container must be labeled with the correct information about the all-natural beverage and alcohol composition contained within the container. In particular, the correct ingredients must be labeled. It is to be further understood that the labeled containers will be visually inspected to ensure that the labels are not misprinted or that the filled containers are not mislabeled.

Step 180—High-Pressure Processing (HPP) of Filled Containers

Once the food grade containers have been filled with the desired amount of all-natural beverage and alcohol composition, the containers have been conventionally sealed or capped and the desired labeling has been attached to the food grade containers, the filled, sealed containers are then processed under high-pressure in a conventional high-pressure processing apparatus (not shown). In particular, filled, sealed containers are placed within the high-pressure processing apparatus. The high-pressure processing apparatus is conventionally closed or sealed. The filled, sealed containers are then subjected to a high-pressure (in a range of 70,000-95,000 psi, preferably in a range of 80,000-90,000 psi) for a time period of 1.5 to 2.5 minutes, preferably for a time period of 2 minutes. It is to be understood that the filled, sealed containers must be kept at this high-pressure range for this period of time in order to achieve the desired 5 log reduction of each bacteria.

It is to be understood that if a particular cycle fails (either the pressure is not maintained for the time period or the time is not properly measured), the high-pressure processing apparatus will conventionally stop and a failure notice will be sent to the processing plant personnel. That particular cycle of processing will then be inspected to determine if the filled, sealed containers and the product contained within those containers that was being processed during that particular cycle have been adversely affected and should be discarded.

Another unique aspect of the present invention is the use of the high-pressures in conjunction with the all-natural beverage and alcohol composition. In particular, the all-natural beverage and alcohol composition is subjected to the very high pressures which result in the inactivation of the spoilage microorganisms such as yeast and mold and other undesirable pathogens. Also, the high pressures reduce the amount of enzymatic activity in the all-natural beverage and alcohol composition. However, the high pressures do not change the taste, appearance, or color of the all-natural beverage and alcohol composition and do not adversely affect the nutritional benefits of the all-natural beverage and alcohol composition. Furthermore, the high pressures reduce the need to sterilize the food grade containers since the reduction of the microorganisms in the all-natural beverage and alcohol composition and the food grade container takes places during the high-pressure processing (HPP).

Step 190—Storage of HPP Processed Containers

After the filled, sealed containers have been processed using HPP, the processed containers are visually inspected to see if any of the processed containers experienced leaks or other container failures due to the high-pressure processing. If any such containers are found, those particular containers will be conventionally discarded. Those containers that have been properly processed are then conventionally transported to a conventional storage facility. In particular, the processed containers are stored on storage racks in the storage facility at ambient/room temperature (between 60 and 75° F.). It is to be understood that the stored containers are periodically, visually inspected to ensure that none of the stored, processed containers have experienced any sort of leakage or failure. If a processed container is discovered to have a failure or leakage, that particular container is then properly disposed of by conventional methods.

Step 200—Shipping, Distribution and Sale of Processed Containers

Upon receipt of an order for processed containers of the all-natural beverage and alcohol composition, the order is conventionally processed by the personnel at the storage facility. The order is then conventionally collected and visually inspected to ensure that no visual contaminants are in any of the processed containers.

Once the order has been collected and inspected, the order to conventionally distributed to the purchaser and the processed containers are subsequently sold.

• • ii. Results—The tests demonstrate the interrelationship between high-pressure processing (HPP) and a composition of an all-natural beverage and alcohol with the effects of pressure and time.
  • iii. The results demonstrate that the compositions of all-natural beverages made with alcohol and not processed using HPP spoil very quickly after production. In particular, the compositions made with all-natural beverages and varying amounts of alcohol show that between a range of 6% alcohol to 14.99% alcohol, the fruit juice mixed with alcohol was not shelf stable. In fact, within 10 days of production, the containers containing the compositions of all-natural beverages made with alcohol and not processed using HPP showed signs of bloating and rancid smell.
  • iv. Across all of the compositions of all-natural beverages made with alcohol and processed using HPP (processed at 87,000 PSI for 180 seconds) retained all of their micro and sensory qualities since the date of production.
  • v. These tests demonstrate that alcohol alone at typical consumption percentages of between 8% and 10% is not enough to preserve an all-natural fruit juice blend. High pressure processing (HPP) is needed to produce a product that can retain its qualities through a distribution process.
