Acidity regulators
During storage, the product can significantly change its acidity. To stabilize the ph value in food, it is widely used acidity regulators.
Acidity regulators used in the production of beverages, meat and fish products, marmalades, jellies, hard and soft caramel, sour dragees, chewing gum, chewing sweets.
According to the European classification acidity regulators combined with antioxidants and ranges from E-300 before E-391.
In the production of sausages, they are added to optimize the ripening of minced meat, and to prevent the development of undesirable microflora. Treating fish with acid solutions contributes to its preservation (and can hide an unpleasant fishy odor). In the production of vegetable juices, organic acids help preserve color during pasteurization.

The components of the buffer mixture are in a state of chemical equilibrium. The pH values of such a system change little upon concentration, dilution, and introduction of relatively small amounts of substances that interact with one of the components of the buffer system. The most common components of the food buffer system are a weak acid (base) and its salt with a strong base (acid). The addition of salts of weak acids or bases can "neutralize" strongly acidic and strongly alkaline solutions.
In the production of meat products, especially raw smoked sausages, maintaining the acidic reaction of the environment is necessary to optimize the ripening processes, in particular, to prevent the development of undesirable microflora and increase the efficiency of nitrite use; for these purposes use glucono delta lactone Due to the addition of acids in sausages and ham products, the conversion of myoglobin into heat-resistant nitrosomyoglobin and nitrosohemoglobin is accelerated. Usually 0.1% citric acid or 0.2 ... 0.3% glucono-delta-lactone is added.
The surface treatment of fish with acid solutions also contributes to its preservation and clarification. In addition, acids bind trimethylamine, thereby eliminating the unpleasant fishy odor. For this reason, they are added to fish breadcrumbs. Lowering the pH in canned food can reduce the sterilization time and temperature.
In the production of vegetable juices, fruit acids are well suited to preserve their color, vitamin C and soften the heat treatment conditions. Dry vegetables are blanched with 0.5% citric acid added to water.
Acid regulators are used in food production in order to reduce the coagulation of proteins and the breakdown of gelling substances when heated, to influence the swelling of gels, to regulate the course of gelling and sucrose inversion processes, to control enzymatic reactions and to increase the yields of food products, to improve their preservation, texture and rheological properties. ... With the help of buffer salts, they regulate and harmonize the taste of fruit desserts, jelly, ice cream and confectionery.
Nutritional supplements
Each of us has heard of food additives with the symbol E. It's not a secret for anyone that nutritional supplements are used today in almost all products. How to learn to distinguish between them, to know which of them are generally prohibited, and which can harm?
Many nutritional supplements- of natural origin. For example, E330 - citric acid - is found in all citrus fruits. Tomatoes contain E160a - carotene, E101 - vitamin B2 riboflavin. E400, sodium alginate, is isolated from seaweed. Sorbic and benzoic acids and their salts are preservatives that are also found in nature, in particular, in mountain ash, lingonberry, and cranberry. Apple contains acetic acid E260, tartaric acid E334, glutamic acid E620, carotene E160a, niacin E375, anthocyanin E163, citric acid E330, succinic acid E363, cystine E920, vitamin C E300, vitamin B E101.
All additives are divided into several categories: not dangerous, harmful, dangerous, very dangerous.

What does the food additive code mean? The letter "E" stands for Europe, and the digital code is a characteristic of the food additive to the product.
1 - dyes;
2 - preservatives,
3 - antioxidants (they prevent product spoilage),
4 - stabilizers (keep its consistency),
5 - emulsifiers (support structure),
6 - enhancers of taste and aroma,
7-8 spare numbers,
9 - anti-flaming, that is, antifoam substances.
Indexes with a four-digit number indicate the presence of sweeteners - substances that keep sugar or salt friable, glazing agents.
Are these additives harmful? Food experts believe that the letter "E" is not so scary: the use of additives is allowed in many countries, most of them have no side effects. But is it?
For example, preservatives E-230, E-231 and E-232 are used in the processing of fruits and they are phenol. Entering our body in small doses, it provokes cancer, and in large doses, it is just pure poison.
In addition, there are food additives that are strictly prohibited in Russia: E-121 is a dye (citrus red), E-240 is an equally dangerous formaldehyde. Powdered aluminum is coded under the sign E-173, which is used to decorate imported sweets and other confectionery products.
But there are also harmless, and even useful "E". For example, additive E-163 (dye) is anthocyanin from grape peel. E-338 (antioxidant) and E-450 (stabilizer) are harmless phosphates that are essential for our bones.
All food additives can be designated by the following letters: O - dangerous; З - prohibited; P - suspicious; P - crustacean; RK - intestinal disorders; VK - harmful to the skin; X is cholesterol; RJ - indigestion; OO is very dangerous; RD - blood pressure; C - rash; GM - genetically modified
Manufacturers do not always indicate the number of the food additive. It also happens that only its name is written on the products. How to figure out whether such an additive is harmful to health or not? The table below shows the names of the additives and their codes.

There are long-standing conversations around "E" - additives in the Russian Federation. On the one hand, there is no doubt about nutritional supplements, each supplement is tested. But on the other hand, even substances such as citric acid and activated carbon are declared "harmful" and "prohibited". What are actually nutritional supplements?
I would like to believe that no one will allow for sale a product on the label of which prohibited additives are declared. And if permitted are declared, then their mass fraction should be checked during certification and not exceed the maximum permissible.
It is believed that the reason for the increased morbidity and mortality in Russia is associated with a decrease in the consumption of natural products that supply the body with the substances necessary for its vital activity, and the replacement of these products with refined, low-quality food, artificially enriched with vitamins and microelements.
Today, many already know, knows that lemonades can be used for kitchen utensils or for cooking jeans. And chewing gum is generally dangerous. And for the children who love her so much! Many types of chewing gum have been found to contain the amino acid phenylalanine in large quantities, and in large quantities it is harmful to the brain, especially the growing one.
Refined foods are also harmful. It has been proven that refined foods can provoke the onset of disease or aggravate the course of existing diseases. According to most experts, the “rationalization” of nutrition, in particular the use of artificially refined products, has become one of the reasons for the development of severe diseases in humans and is a serious pathological factor.
Another scourge of modern food – GMO... In 2003, the moratorium on the development and use of GM products in Europe was lifted. In Russia, the cultivation of transgenic varieties and the creation of new ones is still prohibited, but the import of GM products and their use are allowed. In our country, one type of soybean, three varieties of corn, rapeseed and sugar beet are allowed for consumption, and at the same time not a single transgenic product has been registered that has not been used in less than three countries. Transgenic soybeans, which are added to meat products, are approved by the Ministry of Health. It is registered and used in sixteen countries, including those belonging to the European Union.
What are GMOs? Are they good or bad? The production of food from GM organisms is a relatively young industry. It will take a long time to reliably assess the safety of new products - at least several generations of consumers who use foods or components derived from GM organisms in the diet should change.
There are a lot of genes in the body, and it is impossible to take into account the interaction of all - this is the main trump card of opponents of GM technologies. Someday all genes and all proteins will be studied, and then it will be possible to use the properties of plants and animals that we need without harming them, ourselves or nature. Genetic engineering is a very powerful tool just mastered by humanity. It is not yet possible to make definite decisions about whether or not experiments with GM organisms are allowed or not. To use them or not, we must decide for ourselves. But there are also positive factors in the development of this direction.
Genetically modified sources are used in medicine to create vaccines with increased efficiency. A universal vaccine has already been created that protects against allergic reactions caused by inhalation of pollen from various plants. Its active ingredient is a GM protein. This mutant protein reduces the intensity of painful reactions to pollen tenfold and at the same time mobilizes the immune system to defend the body against the effects of an allergen attack. Preliminary trials of the vaccine have shown that it poses no threat of anaphylactic shock and provides almost the same benefit to everyone suffering from pollen allergies. (based on materials from the European Journal of Immunology)
With the help of GM foods, it is possible to provide food for starving countries, as well as growing populations of other countries in the not too distant future. The world's population has reached 6 billion and will double in the next 50 years. Providing food for the world's population is becoming more and more problematic.
In addition, the grown transgenic crops significantly increase the yield and shelf life of fruits, they become more resistant to pests and adverse conditions. GM vegetables and fruits have been bred, they are able to protect themselves from insects and weeds, they are able to resist viruses, bacteria and fungi, they can tolerate frosts, which in normal cases would destroy the crop.
Some scientists argue that genetically modified plants are much more environmentally friendly than their unmodified counterparts.
Why are we afraid of GMOs? So far, the consequences of consuming products with GMI are unknown. According to leading experts, if a person eats a sausage with transgenes once, nothing will happen to him. But we eat it every day! Experts believe that in many years the genetically modified protein will reach a dangerous concentration in the body. The main source of danger is the imperfection of technologies for obtaining transgenic organisms. Despite the fact that genetic engineering is a highly modern and sufficiently developed science, scientists still act blindly when creating GMOs. Inserting a gene fragment, they do not know exactly which part of the genome it will end up in, and how this will affect its work. The transformed cell acquires completely new, uncharacteristic properties for it.
Some facts of disappearance of whole groups of insects in places where GM plants are grown, the emergence of new mutant forms of weeds and insects, biological and chemical pollution of soils and the gradual loss of biodiversity, especially in the centers of the emergence of cultivated plants, have been scientifically recorded. This is a very urgent problem for Russia, since our country possesses a rich variety of genetic resources of agricultural plants and animals, which must be preserved for future generations.
A number of experiments were carried out on rats: in animals consuming GM products, the cellular structure of the stomach and liver was disturbed, the blood formula changed, the weight of the animals in the experiment and the weight of the brain decreased. These experiments confirmed the assumptions of scientists about the negative impact of GM food on the body: on the immune system, gastrointestinal tract, liver and brain.
Gene manipulation can result in:
- To an unpredictable increase in the content or the appearance of completely new toxins in food.
- Provoke cancer.
- Cause food allergies.
- Destruction of natural ecosystems and disturbance of ecological balance in nature during the cultivation of transgenic plants.
So far, there is no evidence that GMOs can cause abnormalities in the future, but so far there is no evidence that the products are harmless. Time will tell…
In the formation of the consistency of the food system, the pH value is of great importance, with which, in particular, the effectiveness of the action of the additive introduced to solve the technological problem of the formation of the specified rheological properties of the product is related. The effectiveness of the emulsifier, stabilizer, thickener or gelling agent introduced into the food system depends on the pH value of the food mass, as well as on its changes during the technological process of forming the finished food product.
Depending on the specifics of a particular food system, its pH can affect the main colloidal properties that determine the formation of a consistency inherent in a particular product. These properties include:
- stability of dispersed systems (emulsions and suspensions);
- change in viscosity in the presence of a thickener;
- the formation of a gel structure in the presence of a gelling agent;
- imparting a certain taste characteristic of a particular product.
The change in pH is achieved by introducing acidifying or alkalizing substances. To solve this technological problem, food additives of two functional classes are used, combining acids and acidity regulators, which include salts of food acids and some basic substances (see Table 1.1, functional classes 1 and 2)
Acids, bases and salts can be used not only to change the pH of the food system (medium or product), but also to change the buffering properties of the product or give it a sour taste, acidic or alkaline hydrolysis of food raw materials when obtaining a specific product. In some cases, the use of additives of this group may have other, specially specified purposes.
Table 3.39 shows the properties of the most important food acids used to regulate pH in food systems.
Acids approved for use in the food industry are usually harmless to the body, and therefore their use is not limited in hygienic terms, but is regulated by technological instructions for specific food products. An exception is fumaric acid, which has toxicity, the ADI of which is set at 6 mg / kg of human body weight.
Acetic acid (E260) - the most famous food acid, produced in the form of an essence containing 70-80 % the acid itself. In everyday life, vinegar essence diluted with water is used, which is called "table vinegar". Obtained by acetic acid fermentation Salts of this acid are called "acetates". Potassium (E261), sodium (E262), calcium (E263) and ammonium (E264) acetates are allowed for food purposes.The main area of use is canned vegetables and pickled products
Lactic acid (E270) is produced in two forms, differing in concentration: a 40% solution and a concentrate containing at least 70% acid Received by lactic fermentation of sugars Its salts are called lactates For use in food, lactates of sodium (E325), potassium (E326) are allowed, calcium (E327), ammonium (E328) and magnesium (E329), which are introduced into the food system separately or in combination It is used in the production of soft drinks, caramel masses, fermented milk products Has restrictions for use in baby food.
Lemon acid (E330) - a product of citric acid fermentation Sugars Has the mildest taste in comparison with other food acids and does not irritate the mucous membranes of the gastrointestinal tract Citric acid salts - citrates. The regulators of the pH of food systems are citrates of sodium (E331), potassium (E332), calcium (E333), magnesium (E345) and ammonium (E380). Citric acid and its salts are administered separately or in combinations. Citric acid is used in the confectionery industry, in the production of soft drinks and some types of canned fish.

Apple acid (E296) has a less sour taste than lemon and wine. For industrial use, it is obtained synthetically from maleic acid, and therefore the purity criteria limit the content of toxic maleic acid impurities in it. Malic acid salts are called malates. Food additives are malates of ammonium (E349), sodium (E350), potassium (E351) and calcium (E352). Malic acid has the chemical properties of hydroxy acids. When heated to 100 ° C, it turns into anhydride. It is used in the confectionery industry and in the production of soft drinks
Wine acid (E334) is a product of wine-making waste processing (wine yeast and tartar). It does not have any significant irritating effect on the mucous membranes of the gastrointestinal tract and does not undergo metabolic transformations in the human body. The main part (about 80%) is destroyed in the intestine by bacteria. The salts of tartaric acid are called tartrates. Tartaric acid is used in confectionery and soft drinks.
succinic acid (E363) is a by-product of the production of adipic acid. It can also be obtained from amber waste. It possesses chemical properties characteristic of dicarboxylic acids and forms salts, which are called "succinates". At 235 ° C, succinic acid splits off water, forming succinic anhydride. Succinic acid, as well as its salts (sodium, potassium and calcium) can be used to adjust the pH of food systems, which include powdered mixtures for making soft drinks at home, soup concentrates and broths, dry dessert mixtures The maximum content of these additives in food products is regulated and is 3, 5 and 6 g / kg of the product, respectively.
Adipic acid (E355) is produced in industry mainly by two-stage oxidation of cyclohexane. Possesses all chemical properties characteristic of carboxylic acids, in particular forms salts, most of which are soluble in water. Salts of adipic acid are called "adipates". Sodium (E356), potassium (E357) and ammonium (E359) adipates are used as acidity regulators.
The main areas of application are dry flavored and jelly-like desserts, powdered mixtures for making drinks at home, fillings and decorative ingredients for rich bakery and flour confectionery products. The regulated level in products is 1-10 g / kg.
Fumaric acid (E297) is found in many plants and fungi, is formed during the fermentation of carbohydrates in the presence of Aspergillus fumaricus. The industrial method is based on the isomerization of maleic acid under the action of HC1 containing Br. Salts are called fumarates. In the food industry, fumaric acid is used as a substitute for citric and tartaric acids. Possesses toxicity, in connection with which the daily consumption with food is limited to the level of 6 mg / kg of human body weight.
Glucono-5-lactone (E575) is a product of enzymatic oxidation of β, D-glucose, catalyzed under aerobic conditions by the enzyme glucose oxidase. In aqueous solutions, it hydrolyzes to form gluconic acid, the content of which depends on the temperature, concentration and pH of the solution, which makes it possible to regulate the pH of the system. It is used as an acidity regulator and baking powder in products based on minced meat (sausages, wieners, etc.) and dessert mixtures.
Phosphoric acid (E338) is contained in food raw materials and products in free form and in the form of sodium, potassium and calcium salts (phosphates). High concentrations of phosphates are found in milk and some dairy products (cheeses), meat and fish products, some cereals and nuts. In the food industry, it is mainly used in the production of soft drinks, dairy products and confectionery. The FAO-WHO Joint Expert Committee on Food Additives has established an admissible daily dose of phosphoric acid in food, corresponding to 5-15 mg / kg of human body weight, since its excess in the body can lead to an imbalance of calcium and phosphorus. Regulated levels of phosphate in dairy and other products range from 1-5 mg / kg (mg / L) of the product, in processed cheeses and their analogues, as well as in dry mixtures based on flour - up to 20 g / kg (in terms of P 2 О 5).
In addition to the listed additives, hydrochloric acid (E507), sulfuric acid (E513) and its salts - sodium sulfates (E514) and potassium (E515), as well as formic acid (E236), which is usually used as a preservative, can be used to regulate the pH of food systems. The use of these additives is regulated in the framework of technological instructions for specific food products.
Alkalizing substances are introduced into food systems:
- to reduce the acidity of some foods;
- loosening food masses;
- making dry fizzy drinks.
The main group of alkalizing substances are carbon dioxide (carbon dioxide) - E290 and its salts - carbonates and bicarbonates of sodium (E500), potassium (E501), ammonium (E503), magnesium (E504) and iron (E505).
From a hygienic point of view, the use of these additives does not cause any concerns, since they are harmless substances, the dosages of which are regulated only in accordance with technological objectives. Sodium or ammonium carbonate is used as a baking powder in the production of biscuits. In the production of dry effervescent drinks, sodium carbonate is used, with the help of which an imitation of the taste of mineral water is achieved. Sodium carbonate is also used to reduce the acidity of condensed milk.
Some hydroxides of sodium (E524), potassium (E525), calcium (E526), ammonium (E527), magnesium (E528) and oxides of calcium (E529) and magnesium (E530) are also allowed for alkalizing food systems. Their use, like carbonates, is regulated by technological tasks for specific products.
