Patent Application
20150010674
The current invention consists in a completely new range of gelled products, such as gelatin for food consumption or jellies, which include probiotic microorganisms and, in some of its variants, prebiotics, being such products prepared from vegetal origin beverages such as fruit juices, vegetable juices, cereals juices and/or pulse juices, which are subjected to a lactic fermentation process with at least one probiotic strain.
Such beverages, in conjunction with a gelling agent and a number of additives make up the final product which has many beneficial properties for the human organism, derived from microorganisms containing and whose advantages can't be found in the existing state of the art referred to this kind of foodstuff since current methods of making gelled products do not allow the survival of microorganisms, making it impossible to attain the desired objective of improving the consumer health.
More specifically, the strains used for obtaining the probiotics or symbiotic gelled products will be selected among Lactobacillus, Bifidus, Streptococcus and/or yeast, and/or a prebiotic, being these employed in conjunction with gelling agents (gelatin, agar-agar, carrageenan, etc.).
The current invention will have application within the industry for the manufacture of foodstuffs, specifically in the manufacturing of gelled food and/or confectionery.
The development of probiotics in recent decades has meant a breakthrough for food industry. The high number of scientific publications thereon appearing has highlighted clinical and scientific discoveries of very diverse nature related to probiotics.
The term probiotic comes from the Greek and means “pro” for and “bios” life. It is generally used to name certain bacteria associated to beneficial health effects and could be defined as “living microorganisms that upon ingestion in certain proportion, exert a beneficial action beyond the nutritional”. WHO defines them as “living microorganisms which, when supplied in adequate amounts, promote health benefits to the host organism.”
Functional foods are defined as foods that besides its nutritional properties, provide the body biologically active components which contribute to cure diseases or to reduce the risk of suffering them, using proven physiological effects. Besides discussed probiotics, can find prebiotics, which are one type of functional food characterized by comprising non-digestible food ingredients that benefit consumers by stimulating the growth and/or activity of one or several strains of bacteria in the colon, and symbiotic, which include both probiotics and prebiotics.
Probiotic microorganisms consist mainly of species of the genera Lactobacillus and Bifidobacterium, as well as species of other genera as Lactococcus, Enterococcus, Streptococcus and others.
The following effects of probiotic bacteria has been proved: reduce the lactose content of dairy products, promotes the degradation of cholesterol and bile salts, they improve the immune response both local and systemic, inhibit proliferation of pathogens, they produce several beneficial metabolites and vitamins, promote degradation of cholesterol and bile salts, and help to eliminate carcinogenic compounds (American Journal of Clinical Nutrition (2001) Special issue on Prebiotics and Probiotics February: Vol 73 (2 suppl)).
For the years since the first definition, many products have emerged in natural food stores and supermarkets around the world that include the term probiotic in their label. However, it occurs that in some of these, microorganisms have not been adequately tested to ensure they are able to surviving in the conditions (for example, room temperature) or the amount of time (days, weeks or months) necessary from production until it reaches the final consumer.
Probiotic products most usually marketed are fermented milks and yoghurts. In fact, lactic acid bacteria (LAB), among which the species Lactobacillus is, have been used for preserving food by fermentation for thousands of years and can have a double function, acting as leavening agents in foods, may also generate benefits to health.
At present is marketed a number of gelled products where live microorganisms are not included with beneficial health effects. This problem persists because of the difficulty to include probiotics in the product formulation so that they survive a process which involves a heat treatment due to which microorganisms can't survive in sufficient numbers, maintaining such a quantity viable microorganisms in the final product during storage and marketing.
Another drawback associated with most of functional foods that do include probiotics on the market is the fact that they are usually from dairy sources, so people with lactose intolerance can not access the benefits provided by such products. Would be desirable to achieve the fact of to include probiotic microorganisms in food so that these people could consume.
The above problems have been solved with the current invention by employing vegetal origin beverages as a insertion vehicle for microorganisms so that is achieved to add in the formulations probiotics in a wide range of concentrations, obtaining considerable advantages over the industrial usual proceedings in which is not possible to add probiotics, since the gelling agent is mixed with the liquid fraction and the remaining ingredients, and thereafter is took to a very high temperatures to allow the gelification, to which no probiotic microorganisms survive. Furthermore, by the process described herein, with very small amounts of beverage are obtained microorganism concentrations required at the end of the useful life of the final product to ensure probiotic effect.
Are known by the holder of this report the existence of a number of patents registered using plant products as the basis for a lactic fermentation:
Therefore, within the state of the art known the holders of herein, although products of this kind exist in whose compositions include some of the components contained in the invention proposed, none of them include all of the themselves or apply a similar procedure for obtaining them and can therefore be noted that there is no known other invention having characteristics similar to those presented by the invention herein disclosed, being therefore highlighted the novelty of the present invention and which protection is sought for these types of inventions is offered.
The present invention develops in the method of making gelled products and probiotics or symbiotic candies that makes use of gelling agents.
For the purpose of this invention the term “probiotics”, “probiotic micro-organism” or “probiotics” is meant to include any organism, cell content or metabolites of microorganisms that have beneficial effects for the host, both cited in herein other similar properties and behaviours.
The term “prebiotic” herein means any type of food to include in its composition nondigestible food ingredients that benefit the consumer.
The term “symbiotic” herein means any food which includes in its membership both prebiotics probiotic as ingredients.
The term “gelled food product” herein means any food produced using a gelling agent, and other ingredients or additives that can be incorporated.
The products developed in the current invention although different in composition depending on the type of juice or beverage is used, provide gelled foods rich in nutrients, offering different flavours which may be added vitamins, minerals, etc. to possess different nutritional characteristics. These food products are perfectly suitable in dietary control processes through its low calorie content, for people with swallowing problems, for all kinds of people from children to seniors, athletes and people with lactose intolerance because most foods containing probiotics on the market have dairy origin. By using several gelling of vegetal origin products (agar agar, carrageenan), are suitable for vegetarians. Thus we can obtain numerous products with various beneficial health effects.
The inclusion of polysaccharides with prebiotic properties improves survival of the microorganism during the life of the product and the introduction of the microorganism in the intestine after ingestion.
For the gelled products obtaining as described herein were used as raw material various pasteurized or sterilized juices everyday consumer (such as tomato juice, carrot, peach, grape, soymilk and rice drink) to which are added the CECT probiotics (Spanish Type Culture Collection). The inclusion of probiotic strains, has the consequence that the manufactured products possess multiple functional and nutritional properties, depending on each case of bacteria and beverages used.
The lactic acid bacteria used ferment the sugars of used beverage producing lactic acid, volatile compounds and polysaccharides.
All employed beverages have sufficient amount of mono-and disaccharides to ensure fermentation and obtain a good source of probiotic available but may also be added sugars or sweeteners before or after fermentation.
As noted, the basic components for obtaining the gelled products herein will be fermented juice and the gelling agent, although for practical applications proceed to the addition of several elements such as sugars, sweeteners and/or additives, so as to obtain products suitable for commercialization.
The basic method for obtaining gelled with probiotic products entail the following steps which are cited below:
These products can be fortified with vitamins, minerals, proteins, carbohydrates, fatty acids, fiber, or other types of oligosaccharides with bifidogenic effect, or additives to meet the needs of specific sectors of the population, or improve their conservation.
Can also use other types of gelling agents or mixtures thereof with other thickening agents such as locust bean gum, guar gum, xanthan gum, etc.
The gelled products with probiotic and symbiotic properties from the current invention may be used as coating agents of other foods, such as cut products. Also can be employed as fillers in other foods.
For the production of gelled probiotics and/or prebiotics polysaccharides enriched is possible to use many different types of fermentation substrates. Tests have been conducted with very positive results using the following lactic ferments: Streptococcus thermophilus together with Lactobacillus delbruekii subsp. bulgaricus, Lactobacillus rhamnosus, Lactobacillus casei, Lactobacillus acidophilus, Lactobacillus plantarum. Similarly could be incorporated to these products, as probiotic Bifidobacterium species and other Lactobacillus strains.
The obtained products possess the same consistency and other sensory characteristics of commercial gelatins with approximate viscosity values between 10 and 75 mps, humidity between 8% and 13%, while the microbiological tests performed on these products according to the standards microbiological established for edible gelatine showed levels below the limits In the examples have been studied life periods of 30 days, as is done for gelled products sold in refrigeration.
Although it is feasible the use of different percentages of juice or fermented beverage, concentrations of viable probiotic microorganisms obtained when adding a 15% juice or fermented beverage made its use feasible at industrial level as it is within the range of juice that currently used in commercial gelatins. This leads to produce gelatin probiotic, with small variations in the usual processing without major changes in the formulation, yet achieving a significant improvement of the functional properties of the finished product, with additional health benefits over the existing in the current state of the art.
As can be seen in the first three examples of present invention manufacturing practices, had been achieved high concentrations of viable probiotic microorganisms, such as in the finished product at the end of its useful life. These results are independent of the type and amount of juice or fermented beverage employed, and also of the type of probiotic organism.
Another practical application of the present invention is the development of probiotic or symbiotic sweets, starting from the same preparation procedure and including no significant variations. Employment is part of vegetable juices like tomato juice or carrot in conjunction with gelling agents such as gelatin or the like.
Candy with probiotics will consist of the following ingredients that characterize its formulation:
Although, and as indicated in the exemplary embodiments, it is possible to modify one or more of these components in order to provide the final product with some additional property.
In general, any type of valid vegetable juice drinks, cereals and/or legumes, as fermentation substrate for carrying out the production of candies. It will also be possible to add to the fermentation substrate of various types of carbohydrates and sugars as adjuvants. Also exists the possibility of starting from a Jellies fermentation substrate different vegetable juices, such as using milk.
Existing prior knowledge on the use of different lactic acid bacteria for fermentation of various substrates, such as vegetables or milk drinks and other fruit or vegetable juices, lets us know in advance that the fermentation is carried out with the same success as the substrate and ferment used in the present invention in the case of employment of other bacteria such as Bifidobacterium, Streptococcus, other strains of Lactobacillus and/or addition of any yeast or juice drink above.
The obtained products have the same basic sensorial characteristics as Jellies currently on the market, although their nutritional composition is quite different, since they possess probiotic microorganisms and their calorie content is lower than commercial reducing sugars by replacing his drinks formulation or fermented fruit juices, or also by replacing these artificial sweeteners or sugars by nonmetabolizable sugars, also with the possibility of enriched with vitamins, minerals, additives, fatty acids, etc.
Thus we get a range of probiotic gummy, suitable for diabetics, to replace sugars with sweeteners. For vegetarians, to substitute for gelling agents such as gelatin, agar agar, carrageenan, etc., to people in dietary control process, since it reduces the caloric content and for people with lactose intolerance in those formulations which do not contain as fermented drink milk or dairy products.
An important application of the present invention is the use of probiotic formulations as Jellies coating agent or additional ingredient cereals, cookies, candies, etc. after processing, thus being able to obtain a number of probiotic products to which its process so far is very difficult to incorporate microorganisms.
The procedure for obtaining the probiotic gums comprising the following steps:
a) Sterilization of the substrate (juice) and probiotic fermentation.
b) Hydration of the gelatin with the fermented juice until completely dissolved.
c) Dissolution mixed with sugar and glucose syrup and the resulting syrup after cooking.
d) Incorporation of additives (as mentioned above, these additives may be multiple classes, also including prebiotics).
e) cooling the syrup.
f) Adding the gelatin solution.
g) Introduction of the mixture in the reservoir system.
h) Drying of the product in the mold tank.
i) release and product cleanliness.
j) Application of coating agents (oils, carnauba wax, beeswax, etc.).
However, as mentioned, there are variations in certain steps of the process for the preparation of, for example, sugarless gums symbiotic. The procedure in this case would vary product components which involves variations in the preparation process. In any case, the essence of the invention remains unchanged since it is not affected by small variations that may be introduced.
The present invention is illustrated by the following examples, their representation pretending not to limit its scope in any case, either partially or fully:
Materials used: vegetable juices (carrot and tomato), fruit juices (peach and grape). As gelling agent gelatin is used.
Microbiological methods: the petri plate counts were performed for: enterobacteria, Coliforms, Salmonella and Shigella and Clostridium Perfingens, S. aureus, Streptococcus and Lactobacillus.
Firstly must obtain a pasteurized or sterilized substrate, in this particular example juices received UHT treatment. Then fermented at 37° C. for about 24 hours, although this time period may be modified to achieve the convenience for desired microorganism concentration. It is also possible at this stage of manufacturing the addition of monosaccharides and/or disaccharides.
Were used various combinations of St. thermophilus and Lactobacillus:
After fermentation time, it proceeds to the hydration of the gelatin and in parallel it is then dissolved in hot water 80 to 85° C. once the gelatin dissolved in water under aseptic conditions until the temperature decreases 40° C. Once reached this temperature, are added different concentrations of gelatin solution (eg 15% or 50%, although other concentrations can be used above or below the indicated), the mixture is homogenized and is applicable to the packaging of the product, while cooling for about 2 hours, until the proper consistency and kept refrigerated at 4° C. To the ingredients can be added sugar, sweeteners, vitamins, minerals, fiber, thickeners, dyes or fragrances.
In order to study the viability of probiotic bacteria, microbiological count was performed after processing and after 30 days of cold preservation, for the following products:

In conclusion we can state that in all cases, the microorganisms remain with the same order of viability in the initial concentrations, being within the ranges recommended for products containing probiotics at the end of its useful life (106-107 cfu/g).
Materials used: This example was performed using as gelling agent agar, tomato juice and inulin.
Microbiological methods: the petri plate counts were performed for: enterobacteria, Coliforms, Salmonella and Shigella and Clostridium perfingens, S. aureus and Lactobacillus.
First, must be obtained pasteurized or sterilized substrate, in this case the tomato juice received UHT treatment. Then fermented at 37° C. for about 24 hours, to obtain the desired microorganism concentration, although this step may be performed with different fermentation times and with and without addition of monosaccharides and disaccharides. Fermentation takes place with Lactobacillus plantarum. Prior knowledge of the use of this probiotic together with inulin indicates that the addition of inulin can be performed before or after finishing the fermentation, fermenting microorganism such as first substrate sugars from inulin using the long term.
After the fermentation time, the gelled product is made with agar, maintaining boiling for approximately 7 minutes and left under aseptic conditions to decrease the temperature to about 40° C. Once reached this temperature, there are added various concentrations of fermented juice: 15%, 30% and 50% (although it can use any or lower concentration than indicated), and inulin (between 0, 1 and 3 g). Is homogenized and then proceed to the packaging of the product, cooling for about 45 minutes, to achieve the proper consistency and kept refrigerated at 4° C. To the ingredients can be added sugar, sweeteners, vitamins, minerals, fiber, thickeners, dyes or fragrances.
To study the viability of probiotic bacteria were counted after processing microbiological and 30 days of cold preservation, as in Example 1, for the following products:
L. plantarum
L. plantarum
L. plantarum
Results show that the viability of Lactobacillus plantarum remains in the same order after 30 days of storage, regardless of the amount of juice used in the formulation (15, 30, 50%). Inulin improves survival of the microorganism during the product life.
Materials used: This assay was performed using carrageenan as gelling agent, rice and soybean beverage.
Microbiological methods: the petri plate counts were performed for: enterobacteria, Coliforms, Salmonella and Shigella and Clostridium perfingens, S. aureus and Lactobacillus.
First, must be obtained pasteurized or sterilized substrate, in this case the rice and soya drinks received a UHT treatment. Then fermented at 37° C. between 4 and 6 hours, until pH 4.5. Fermentation was carried out with Lactobacillus acidophilus and Lactobacillus rhamnosus.
After the fermentation time is performed with carrageenan gelled product, increasing the temperature to 60-70° C. and left under aseptic conditions to decrease the temperature to about 40-45° C. Once reached this temperature, there are added various concentrations of fermented beverage: 20% and 40% (although it can use any or lower concentration than indicated). Is homogenized and then proceed to the packaging of the product, cooling for about 45-60 minutes, to achieve the proper consistency and kept refrigerated at 4° C. To the ingredients can be added sugar, sweeteners, vitamins, minerals, fiber, thickeners, dyes or fragrances to alter their organoleptic characteristics.
To study the concentration of viable probiotic microorganisms in the final product were counted after developing microbiological products.
Results for both beverages tested showed that the concentrations of viable microorganisms are of the order of the recommended amounts of probiotics, and various fermented beverage percentages used in the formulation.
L. acidophilus
L. rhamnosus
This example uses the following ingredients, in the proportions reflected in volume, that will conform the final product:
Manufacturing Process:
To study the viability of the probiotic microorganism, was performed in microbiological count after working at 30 and 60 days of refrigerated storage at 4° C. (Table 12).
L. plantarum (u.f.c./g)
Conclusion it can be asserted that in all cases, the organisms remain in the same order of viability in the initial concentrations during the two months of refrigerated storage. Subsequent studies verified the end of the useful life of both product and probiotic microorganism.
This example uses the following ingredients, in the proportions reflected in volume, that will conform the final product:
1. Carrot juice Fermenting with L. plantarum during 24 h at 37° C., to obtain the desired microorganism concentration, although there is the possibility of testing with different fermentation times with and without addition of monosaccharides and disaccharides.
2. Hydrate the gelatin with the juice fermented at 37° C. until completely dissolved.
3. Dissolve the acesulfame potassium and mixed with maltitol syrup, boiling at about 115° C.
4. Add the prebiotic, inulin and in this case citric acid. If desired, colorants can be added, or other additives such as vitamins, minerals, etc.
5. Cool the syrup to 40° C. approximately.
6. Add the gelatin solution.
7. This product is inserted into the deposit system and deposited into starch molds.
8. The molds are cooled in a refrigerated 2-4° C. for about 8 hours for the candy to cool and solidify.
9. Unmold candy and remove the starch adhered to these.
10. Apply coating agents (oils, carnauba wax, beeswax, etc.).
To check the probiotic's viability, microbiological count was performed after preparation (Table 13).
L. plantarum (u.f.c./g)
