FOOD ADDITIVES AND RELATIVE HEALTH-HAZARDS OF SYNTHETIC AND SEMI-SYNTHETIC PRODUCTS
Food in a daily diet should promote a control of some function of the organism. The healthy food and the problem of a healthy nutrition production includes social, economic, research-and-production, medical, biologic and historical aspects. Among components for manufacture of healthy food, CO2-extracts being concentrates of natural substances of plants, multifunctional additives with rich external (aroma, taste) and internal (BAS compounds) content, take firm positions. CO2-extracts are natural food components.
It would be naive to assume that new chemical additives being applied according to certificates in dozes not exceeding the allowable ones, (referring to an estimation of the United Committee of Experts of Food and Agriculture Organization / World Health Organization) one can use daily during his (her) lifetime without any risk for the life, and that they are harmless for our organism, especially for children's' and teenagers'.
For children under three years a special nutrition is made, and a schoolboy (a schoolgirl) uses practically all as an adult person, and many products in much more amounts: drinks, sweets, sausages.
The statistics evidence:
- each city dweller consumes 68 kg of food additives, especially with drinks, sausage products, pastes and other food (vitamins, trace elements and amino-acids are not included);
- 0.5 kg (about 2000 names) of synthetic additives are used for colouring, preservation, improvement of food taste, strengthening of food smell, synthetic, artificial and "identical to natural" aromatizers are used to replace more expensive natural components;
- for about 9000 names of synthetic substances made today, no reliable methods of test are available but they are used for food purposes, 450 chemical additives are only checked up, and 80 per cent of them declared to be harmless, 14 per cent probably harmless, 5 per cent declared to be doubtful;
- it is proved that 35 per cent of cancer reasons is poor-quality food (according to P. Ravell's data, 1995) and 1 per cent of cancer emergences is due to synthetic additives (also according to P. Ravell's data, 1995);
- 1 per cent of cancer diseases are caused by colorants, packing and wrapping materials.
The majority does not wish to eat colorants: fermented rice, tartrazine, carmoisin, etc., as well as those 80 per cent of the world market aromatizers which contain artificial and synthetic aroma-and-taste substances. 19 per cent of 1000 school-age children in 1979 were constantly hungry; 59 per cent of them were constantly hungry in 1997.
- " school-agers consume excessive amount of such food components as phosphates and nitrite of sodium in meat products, and benzoic acid in freshening drinks, especially during summer period. The drinks are supersaturated with synthetic colorants, aromatizers and acids;
- " school-agers' and young people's organisms are more than others' polluted with preservatives (sorbic and sulphurous acids, sodium benzoate), with fixatives of sausage colour and of chees preservatives (nitrite of sodium), stabilizers of consistence, accelerators of maturing, bleaches, surfactants, etc.
- 738 samples of products taken from retail outlets when checking the content of some food additives, have shown the excess of filling rates on nitrites - 12 per cent, on sulphurous acid - 52 per cent, on benzoic acid - 29.2 per cent;
- 11 per cent of dairy, fish and meat products, 17 per cent of drinks and 5 per cent of children's nutrition do not meet the requirements on microbiological parameters.
All this has generated a natural reaction of the society: a protection against alien, unnatural and dangerous food components.
Concern of the population about their own health and about health of the children has raised the following trends:
- intensified production and consumption of qualitative and safe food;
- development of food technologies requiring natural non-polluting sources of biologically active substances, as well as aromatic and flavouring additives;
- development of non-polluting manufactures or closing to non-polluting as far as possible;
- more strict government regulation on availability of undesirable impurities, especially in food stuff;
- energy costs increase;
- expansion of natural products and sources of aroma-and-taste additives range, and in this connection, an increasing development of pure extraction technologies of such products.
Extraction gasoline (hexane) and other organic solvents (freon-11, nefraces, etc.) for production of food components with aroma-and-taste properties, simultaneously being concentrates of natural biologically active substances of plants, are not listed in the Table. There are several reasons of it: lability of the components included in such a system, a residual content of extragents in dissolved and chemisorbed state.
It is well-known that beginning from 3.0 - 1.5 per cent of an extragent in a product, its removal makes more difficulties than the removal of previous 97.0 - 98.5 per cent. A replacement of the solvent or extragent brand is allowed with permission of Ministry of Health on submitting the data about distillation mode and full removal of the solvent from the product. Tough extraction technologies with live steam and other methods are used for extraction of vegetable food oils of a poor quality but not of aroma-and-taste products.
Liquid carbon dioxide (liquid CO2, liquefied carbonic gas) being a natural component of environment and our organism, is accepted to be most pure, safe and natural solvent for a human body.
So, now the most important problem for us is not formation of a non-polluting manufacture, - it already exists, not production of natural harmless products which are CO2-extracts and raw materials treated with liquid CO2 (id est. CO2-raw materials) but the fastest implementation of these products in various branches of the national economy, overcoming of synthetic and artificial food additives pressing, wide consumers acquaintance with CO2-products, revealing advantages of our products and specific recommendations on their application.
II. Human ecology, nutrition and CO2-extracts
Today food, pharmaceutical, perfumery-and-cosmetic and other industries need every possible additives: aromatic, flavouring, vitamin, bioactivators, stabilizers, preservatives, etc. Let's roughly divide all additives into natural and synthesized ones. Chemistry can all, however this "all" in the nature is richer and more balanced. Hence rendering the chemists their due, nevertheless we should note: now and then the competition raises most inconceivable, rash and even ecologically dangerous steps in this direction. A mass of synthetic food additives being very price-attractive has captivated the Russian market. Probably businessmen (businesswomen) using them, don't know that they involuntarily participate in ecocide of human beings. Some substances present in food additives in micro amounts, transiting from packing containers, as well as synthetic additives, are chemical mutagens for people. And so, based on various international documents, for health of today's people and of the descendants, we are obliged to use mainly natural additives. In advanced countries movements of ecologists, businessmen and scientists for use of non-polluting food and for non-polluting technological processes of food production take place. For example, Hipp Company being a manufacturer of children's nutrition, only applies as additives vitamin compositions balanced by the nature itself, and antioxidants of vegetable raw materials.
The most significant achievement to receive safe non-polluting extracts is a correct choice of a substance being the extragent, the substance which is everywhere around us, a product of our vital functions, - carbon dioxide.
Let's now consider the extracts received by means of liquid CO2.
It is even impossible to compare the aromatizers and target substances manufactured using the CO2-extraction, with the synthetic products sold now and flooded the market of our country. All over the world the interest to decode smells at the level of substance components already decreases, as well as the interest to receive synthetic analogues with the name of a product's aroma and to use them in the food industry. It is from where we consume now the aromas simulating natural drinks, the smell of smoked products and meat, the aromas of various expensive cognacs. In the best case it is used for flavouring refined products, in the worse one - for substitutes, fillers, etc.
The nutritious and vital value of such products is insignificant.
Let's compare synthetic aromatizers with the natural rich multicomponent substances received from plants with which we decided to replace unnecessary synthetics alien to our organism. In particular, consuming processed meat products and huge amount of flavoured water, we spoil stomach, damage liver and kidneys, disturb microflora of intestines, while the CO2-extracts received really from the heart of vegetable cell, improve appetite, supply an organism with a balanced set of vitamins and trace elements, biologically active substances, antioxidants protecting a person against ageing. CO2-extracts are natural harmless products of XXI century transmitting aroma and taste of the plant. And unlike most used plants, they are free of such a defect as semination with dangerous micro-organisms. CO2-extracts are natural preservatives and antioxidants.
III. What are CO2-extracts? What are their advantages?
The extractions, CO2-extracts received by a "cold" method (the temperature is equal up to 30?С), being ready forms for direct use in various fields of the national economy, represent absolute concentrates typical for each kind of raw materials and have a part of the properties of a raw material, based on which they are manufactured. CO2-extracts, unlike the plant itself, are free of such a defect, as semination with micro-organisms causing damage of the product. Especially it is important when using classical spices, where not only germ semination is high but also concentration of aflatoxins is high. The concentration of aflatoxins in import raw materials such as peanut, pistachios, corn and spices, amounts to 500 - 15000 mkg / kg, and that requires special costs for sterilization against the semination, as well as for removal of aflatoxins.
- have strongly pronounced aromas of dry spices of the same name;
- do not lose their properties, aroma and taste during storage (three years and more according to the certificates at normal conditions);
- are not damaged by vermin;
- are simple in use: on solid and liquid carriers (food additives, multipurpose additives, sugar, salt, as emulsions, solutions in fats and oils, in 80-per cent vinegar, etc.);
- easily combine compositions of spices and various "bouquets";
- are practically non-polluting products;
- unlike dry spices, they are not seminated microbiologically, are sterile and have bactericidal and bacteriostatic properties that prolongs products shelf life;
- unlike dry raw materials, especially tropical and subtropical ones, they are not littered with mycotoxins (aflatoxins) being products of vital functions of microflora;
- are received using high technologies at room temperatures and without oxygen, by means of a non-polar solvent (liquid carbonic acid of the food class). Doing so, liquid CO2 instantly disappears, leaving pure natural CO2-extract;
- unlike oleoresins and ether oils, they have flying components of ether oil in a combination with non-volatile flavouring components of oleoresins;
- are used all over the world, included into the series of high-quality products and of products of the "Health" line;
- unlike other kinds of extracts, they are not exposed to heat treatment when recuperating solvents;
- are most complicated combination of target and accompanying substances not doing harm an organism, whereas high-purity target components received even from natural sources, can harm an organism;
- are very complex natural system of a non-lipidic fraction (volatile hydrocarbons; carbonyl compounds, because of which CO2-extracts are appreciated, etc.), and lipidic fraction (fat acids, sterols - provitamin D; tocopherols - vitamin Е and those with antioxidant activity, carotenoids - provitamin A, organophosphorus compounds), vitamin C and of group B, vitamin E - phillohinon, waxes, organic acids, polyunsaturated fat acids and others. Id est., except for aroma and taste, CO2-extracts contain physiologically active substances, salutarily influencing our organism in the century of synthetics and chemical additives.
CO2-extract of red hot pepper represents oily liquid of dark orange up to brown colour with a typical keen-spicy aroma and hot taste. An important component of the red hot pepper extract is capsaicin (alkaloid-like amine giving the product hot taste.) Besides, there are carotenoids in this extract, vitamin C and others, polyatomic phenols with antioxidizing properties. The biostimulation effect of CO2-extract of red hot pepper consists in excitation of integument, initiation of local blood rush, and consequently, metabolism raising general tonus.
CO2-extract of red hot pepper contain: fat-like substances - 69 per cent, saponified fraction - 16.1 per cent, carbonyls - 0.36 per cent, spirits - 9.33 per cent, carbohydrates - 1.17 per cent, capsaicin - 0.5 - 0.8 per cent and more. CO2-extract of black bitter pepper represents oily dark brown liquid with a yellow residuum, very strong smell and taste of black pepper. It comprises as follows: terpenoids as hydrocarbons and acid-containing compounds creating a specific aroma of black pepper. The food bitterness is caused by availability of alkaloids: piperine, havicine and others. The integrated content of various classes organic compounds makes this extract very convenient and advantageous when using it as a food additive in the process of manufacturing sausage products, fish canned food, preserves and other products of public catering as an independent aromatiser, as well as in mixtures with other aromatic products. Dosage and introduction of it do not make any difficulties. Unlike dry black bitter pepper, CO2-extract of black bitter pepper doesn't require special storage conditions, temperature and humidity control when long keeping. CO2-extract of black bitter pepper contains: 40 - 45 per cent of bitter substances, such as free-state alkaloids, piperine - 28.7 - 37.7 per cent, vitamin C - 0.01 per cent, vitamin B - (0.4 - 0.5) х 10-3 per cent, etc. Before further comparing CO2-extracts with the extracts received by other solvents, we compare MCL (maximum concentration limits) of some of them:
a) gasoline - solvent (narcotic effect) MCL рз 300 (п);
b) benzene (drug, affect hematosis) MCL рз 1 (п) II class;
c) freon-253 (drug) MCL рз 1 (п) II class.
One can assert that liquid CO2 is an ideal solvent, especially to receive food and medical products.
Besides, freons in particular are forbidden for wide application by the Geneva Convention in connection with the destroying influence on the ozone layer of the Planet.
In addition, it is known from practice that to get rid absolutely of a harmful
solvent, to remove it from an extract using various technological methods, is
very difficult and expensive, and sometimes it is practically impossible: appreciable
traces of the solvent remain. One can remove it either having spoiled the extract,
or rising it in price incredibly, or using again liquid CO2 for removing the rests
of the solvent. Nefrace extracts get littered with aromatic carbohydrates
contained in the solvent itself (according to the Certificates it is up to 0.1
per cent of the total mass). The boil-off for nefrace 65/70 occurs beginning
from 65° C, and this is not acceptable for labile components of vegetable
Freon extracts are studied poorly but it is known that interactions of freon
molecules with extracts are possible; the solvent is separated from an extract
with difficulty; besides most of freons are forbidden as solvents in the food
industry. There are no convincing data about their influence on a human organism,
as well as reliable methods of determining a residual concentration of these solvents
in the extracts. The following is important: the extraction process using liquefied
CO2 is truly waste-free.
NATURAL CO2-EXTRACTS FOR CHILDREN'S
CO2-extracts being concentrate of natural substances of plants, take a very important place among other components for production of healthy food.
CO2-extracts are multifunctional additives with rich external (aroma and taste) and internal (compounds of biologically active substances) content that makes them necessary for the children's nutrition.
Two categories of children are especially subject to the "food stresses": the ones passed from the children's nutrition to the "adult's" (two or three years old) and the schoolchildren. The first ones, because the nutrition is practically not produced for children from one- to three-years old. This market is only complete by 1/7 of the demand. The second ones, because the influence of the family on the nutrition nature decreases with the change of living pattern (full employment of parents at work, longer studies at school, etc.) The home time of the children reduces, together with it a normal procedure of nutrition disturbs, and its quality becomes worse. Still in the early 20th century a Norwegian Shnots suggested to enlarge home nutrition of children with a gratuitous school one (an afternoon snack or second breakfast) not dependent on social and economic position of a child's family.
When manufacturing food stuffs for children: canned fish, meat, vegetable,
groats and their mixtures; frankfurters, sausage, meat half-finished, dairy and
bakery products, a special proper approach to the quality of the basic raw materials
and to their aroma-and-taste components exists.
- For dry spicy aromatic plants are typical as follows: season prevalence of the harvest and remoteness from places of use; long storage in warehouses; warehouse vermin's excrements impurity, pathogenic microflora and products of its vital functions (toxins).
- As for children, artificial flavour and aromatic additives are undesirable, most of them are very harmful.
- Ether oils and their preparations as emulsions have small shelf lives, do not transmit the natural taste and smell of spices, contain emulsifiers lacking food value. Under the influence of air oxygen, humidity, heat and light, ether oils undergo composition changes owing to the oxidation and polymerization. Ether oils are most subject to falsification by artificial aromatizers, including synthetic ones, and by surfactants. The steaming known still from the extreme antiquity, is more suitable for the perfumery industry.
Application of CO2-extracts in children's nutrition is most progressive.
Up-to-date technologies using liquefied food CO2 gas at the temperature up to 30?С without oxygen, allow receiving CO2-extracts which completely transmit the taste, aroma and most of useful properties of the plants that is especially necessary for our children in the century of refined food domination. The CO2-extracts improve food quality, increase its shelf life. CO2-extracts of parsley, dill, celery, pimento, coriander, nutmeg and other spicy plants are included practically in all formulas of children's nutrition developed by the Institute of Meat Industry.
Shelf lives of CO2-extracts are equal to three years and more at normal conditions that proves the existence of powerful natural bactericidal and antioxidant properties.
CO2-extracts are included in some specifications for special nutrition, are technological in use, easily dosed by volume and perfectly distributed when mixing in cutters and mixers. Many people ask how to introduce a CO2-extract in a product, for example, 2 - 5 ml of the pimento CO2-extract.
One should put it on sugar or on small amount of salt (about 100 -200 g) using a plastic measured syringe, which is much faster, than weighing 50 - 100 g of a dry spice. Then mix by means of two or three motions, and introduce in any product.
A big work is carried out at the Borisoglebsk Plant of Canned Meat being an
enterprise of the high technological efficiency, where several methods of introducing
CO2-extracts in a cutter were tested: the above described one with depositing
on salt, sugar, semolina, dry milk in vegetable oil, and direct introduction on
the surface from a suitable medical syringe (without a needle) shortly before
the end of the cuttering (during rotation of the cutter bowl). The forcemeat former
himself chose a method of the introduction. The most important for us was the
uniformity of CO2-extract distribution at all methods of introducing into the
forcemeat. The results appeared to be excellent: the CO2-extract was distributed
uniformly in all parts of the volume at any method.
The consciousness of the fact that natural useful CO2-extracts are applied in the manufacture of foodstuffs generates among workers of the enterprise a serious, careful and respectful attitude to them. Really, CO2-extracts of spicy plants are worthy to be irreplaceable in children's nutrition: they raise the secretion of digestive glands, increase the digestive ability of generated enzymes, and protect the digestive system as they have anti-inflammatory properties. They improve egestive functions cleaning the organism of slags in due time; they are carminative, softly eccoprotic and diuretic agents. Unlike dry spices, they do not bring an additional microflora in a product, have a bactericidal or bacteriostatic effect on microflora of the product; show strong antioxidant properties. Based on the chemical composition, CO2-extracts inherit individual properties only immanent to this plant, in addition to the general properties attendant to all spicy plants.
Let's consider the chemical composition of most frequent for children's nutrition spicy plants:
The CO2-extract of celery contains mainly the following substances: d-limonene,
d-selinene, lactone sedanolide, anhydride of sedanon acid, furocumarine bergaptene
and glucosides, phenols and carotenoids, organic acids, tocopherols, petrozelene,
petrozelaidene, oleinic, linoleic acids, etc. in small amounts. It is of interest
that the basic lovage, celery-spicy smell and taste of the CO2-extract is practically
due to two substances which amount is less than 3 per cent of the extract. The
non-strong, "short" smell of celery is very stable at minimum dosages
of the CO2-extract. It is capable to strengthen the taste and aroma of many accompanying
aroma-and-taste substances. Certainly, one can divide the CO2-extract by fractions,
receive ether oil or the substances "responsible" for the celery smell,
and then using a liquid or dry carrier, offer a "celery aromatiser"
to the food industry. However ether oil or 3-n-butylidenephalide and 3-n-butylphalide
cannot be the substitutes of celery in children's nutrition. As it was noted above,
the CO-extract of celery being a complex natural system of a huge number of substances
transmits the complex unique taste, smell and useful qualities of celery. The
celery is especially esteemed in European and Chinese cooking and in cuisines
of other countries.
Celery raises the general vitality of an organism, especially in case of intellectual fatigability, promotes removing slags, has a high antioxidant activity, is useful by adiposity.
The CO2-extract of parsley contains apiole, ?-pinene, myristicin, flavone glycosides,
furocumarine bergaptene, tocopherols, carotenoids, fat oil in which composition
are mainly petrozelene, oleinic, linolenic and palmitin acids. Parsley has spasmolysant
and anti-inflammatory properties. It is applied for a long time by dysmenorrhea,
kidneys diseases, oedemas, urolithic diseases.
The CO2-extract of parsley in small amounts also strengthens some smells and the taste of a product, practically not relieving of the bouquet.
The CO2-extract of dill contains d-carvone, d-limonene, d-phellandrene, ?-pinene, dipentene, tocopherols and other specific substances, including fat oil, parts of which are oleinic, petrozelene, linolenic and palmitin acids. The CO2-extract of dill strengthens motility of the digestive system, promotes normalization of metabolism, improves discharge of bronchial slime, is useful by a plentiful protein diet, etc. The CO2-extract of dill in small amounts freshens the taste of fish and meat, improves dough, levelling the flour taste.
The CO2-extract of laurel contains cineole, pinenes, phellandrene, linalool, geraniol, eugenol, bitterness, laurel, oleinic, palmitin, stearin, meristic acids, pigments, organic acids, polyvitamins, etc. It is widely used in the meat, fish and vegetable-canning industries. One should introduce the CO2-extract of laurel in products for diabetics. It decreases sugar concentration in blood. The extract cleans an organism of salt slagging, promotes digestion of sour and salty dishes, and softens cough and fever of children. The CO2-extract of laurel freshens meat. It was not applied earlier as a powder, in particular, in boiled sausages, because it changed the colour. The fillings rates are very little but effective.
The CO2-extract of coriander contains linalool, pinenes, dipentene, cymene, tocopherols, pigments, vitamins, non-saturated fat acids as parts of fat oil. This universal extract except for the common above-named properties, is useful by kidney failures, is a strong choleretic agent that is valuable for superfatted products, antiseptical one: it quickly heals ulcers, scissures, it is a helminthicide remedy. The CO2-extract is especially valuable as seeds of coriander are partly struck by mould fungus.
The CO2-extract of clove contains mainly eugenol. It is a powerful antioxidant
and antiseptic, is capable to remove unpleasant smells. Products with the CO2-extract
of clove are especially useful to the organism struck by helminthes. Clove is
considered to improve memory. CO2-extracts of pimento, cinnamon, caraway seeds,
juniper, basil, balm, anise and other plants are also useful. CO2-extracts of
yeasty residua of grape wines (concentrates of natural provitamin D,) of grape
seeds, milfoil, sea buckthorn marcs, peppery mint, germs of wheat (a concentrate
of natural tocopherols and some other substances, etc. are offered for preventive
and dietetic therapy. In children's nutrition based on meat (under 1 year old)
the CO2-extract of parsley (0.0015 per cent of the total mass of a product), or
a compound made of CO2-extracts of parsley, dill, celery in different ratios (1:1:0,5,
2:1:0, etc.) are used. Addition of the dill CO2-extract in sour-milk products,
especially in cottage cheese ones in the same amounts, improve assimilability
and allow avoiding flatulence.
CO2-extracts of dill, parsley, celery, also prevail in foodstuffs for children of 1 - 3 years old but the food consistence is to be changed.
Manufacture of preschool and school nutrition develops very fast in the meat
industry: the range of frankfurters, boiled, half-smoked, summer sausages, delicacy
products, canned meat and half-finished products is wide. The special requirements
made of raw materials are also extended to spices. They must be natural, their
technology must be harmless. By the composition, they must be maximally close
to dry spices but inherent disadvantages of the latter must be excluded. Those
are CO2-extracts. Below a table of approximate dry spices replacements with CO2-extracts
of the same name for the meat industry is given. CO2-extracts are easily dosed
by a syringe of the suitable capacity.

The application of CO2-extracts in children's nutrition is not limited within the meat processing branch.
Use of CO2-extracts in drinks
Formation of natural, energy, functional, cooling and other lines of drinks demands new components to make up a micro-nutrimental deficiency in a child's organism. Earlier transparent soft drinks with a pure aromatic line considered to be a standard. Adding natural juices to them has resulted in the creation of a series of drinks being simulators of natural juices with haziness agents, colorants, artificial aromatizers and substitutes of sugar. It is time to offer consumers some soft drinks with CO2-extracts of citrus plants zest, of aromatic herbs harvests and other vegetable raw materials. The drinks would be not aerated, of various flavour scale (sweet, sour-sweet, etc.) Such drinks were already developed several years ago, however the expanded production of the product range available nowadays at the market, stopped this work. CO2-extracts allow receiving a good flavour quality, a pleasant bouquet, a natural unostentatious residual taste, and chiefly, - a novelty and possibility to manufacture a huge range of various orientation drinks. In the experimental examples, CO2-extracts of coriander, clove, citrus plants, brier and others were used. A production of drinks is possible with addition of "cold" herb shrot tinctures after CO2-extraction in order to preserve a greater nativity of the comprising compounds, with addition of natural juice concentrates etc. For the shrot tinctures after a CO2-extraction, a saturated taste is typical because of a bigger concentration of dry substances than in case of infusion with the same raw material but without a preliminary treatment with the liquefied CO2. The shrots after a CO2-preparation are sterile, id est. no rigid thermal treatment is required. The concentration of CO2-extracts amounted to 0.01 - 0.05 litres per 1000 dkl (depending on the kind of the initial raw material.) One can introduce CO2-extracts using glucose, sugar, their mixture with citric or ascorbic acids, or emulsions with juice, juice concentrate and syrup.
Use of CO2-extracts for ice-cream production
Application of natural CO2-extracts in ice-cream production is a completely technological process. The existence of wide range of natural CO2-extracts from spicy aromatic, medicinal and ether-oil vegetable raw materials, as well as of some waste products of juice production and winemaking, their full and uniform solubility in fats, allows forming a completely new version of ice-cream with biologically active substances received by the cold method too. The filling rates of CO2-extracts or their compounds are 0.002 - 0.050 per cent of the total mass of a product. Specialists of the branch will be attracted by the possibility to unit the taste, aroma and other useful properties of plants in a single bouquet.
CO2-extracts for children's sports nutrition
The experience of development of drinks and cocktails for sports people based on soya, dairy and wheyey proteins and pectines with addition of glucose and ascorbic acid, already exists. With the participation of a sports people group, protein, carbohydrate and other cocktails with addition of CO2-extracts or their compounds have been developed and tested. By analogy one can offer such products not only for young sports people but also for kindergartens, schools, etc.. The ability of CO2-extracts to be deposited easily and uniformly on loose dry products: flour, proteins, pectines, glucose, sugar, salt, vegetable powders of sublimation drying and on their mixtures preserving the product loose, allows producing dry cocktails of various packing, including single-time ones. Proteins and other functional products are easily assimilated by an organism when using cocktails with CO2-extracts, quickly supply the shortage of micro nutrients. Using a general basis, one can by a simple mixing of components easily and quickly receive a wide spectrum of useful cocktails with CO2-extracts for different age groups of children with due regard for physical and physiological features, seasonal and other changes. The niche for manufacturing such products is not occupied, and the products will be required in children's nutrition. The convenience of their transportation and use will speed up their promotion to the market.
The children's nutrition as a social category, especially draws attention of food industry workers today. Considering not only aroma-and-taste parameters but also physiological effect on the organism, CO2-extracts take not the last place when developing domestic foodstuffs for children of different age.
