How and from what sausage is made - food additivesWhite-sided ham, and then I bought teskoma
Now it's time to understand what meat products are, how they are processed, how sausage is made, what is put into it and what is the result.
For a long time, I have several books on cooking homemade sausage, which are quite clear and reasonably written, and which I periodically use when I cook meat and ham.
Now I specially bought two more books:
- Biophysics of environmentally friendly meat processing. How and from what sausage is made. Author D. B. N., leading researcher at the Institute of Cell Biophysics, RAS Vekshin N. A.
- Making sausages, corned beef and ham. As amended in 1923, author and compiler Professor D. V. DEVELI bring to your attention several materials from this book by Vekshin N. A. I hope this will help you in understanding what a sausage is.
NUTRITIONAL SUPPLEMENTSNutritional supplements - substances that for technological purposes are added to food products during production, packaging, transportation or storage to give them the desired properties, for example, a certain aroma (flavorings), color (dyes), shelf life (preservatives), taste (flavor enhancers) , consistency (thickeners), etc.
Food additives are never consumed independently, but are introduced into food products to give the latter the desired organoleptic properties (taste, color, odor, consistency and appearance), preserve food and biological value, improve processing conditions, packaging, packaging, transportation and storage, and also increase the shelf life of products.
Food additives are used to protect sausages from the growth of pathogens (for example, the causative agent of botulism), to improve color (sodium nitrite), enhance taste (monosodium glutamate, sodium inosinate), weight gain (water with salts and gelling agents), etc. ...
Food additives have long and firmly entered the meat processing, especially in the manufacture of sausages, small sausages, sausages, etc. In the absence of additives, destruction, rancidity and spoilage occur (Antipova L. V. et al. Methods of research of meat and meat products. M .: Kolos, 2004). In this case, the natural red-pink color is lost and a dark brown color is acquired (due to the transition of oxymyoglobin to metmyoglobin).
Food additives in the form of mixtures have become widespread: nitrite mixtures, protein mixtures, phosphate mixtures, mixtures of natural spices, mixtures of water-soluble spices, multifunctional mixtures, flavorings, ripening accelerators, etc.
Food additives stabilize the minced meat, preserve it, give it a pleasant red-pink color, and also enhance the binding of water (in order to increase weight and volume). However, environmental friendliness and safety of additives for consumer health are usually not at the forefront.
The criterion for the correctness of the selected food additives of the meat processing plant is the absence of visible damage (blackening, mold) or unpleasant odor of the resulting product, the preservation of a pleasant color of the product and its good taste. Manufacturers, as a rule, overuse spices, flavors, dyes and other chemicals, imitating the natural color and taste.
In recent years, in the West, as a harmless natural preservative for the storage of a number of
dairy products calcium ions are used. Apparently, calcium can be used in many cases for meat products.But it cannot be used simultaneously in a mixture with ditricarboxylic acids and bicarbonate without an inert filler (otherwise there will be an insoluble precipitate), or the application must be separated by stages in time.
The formation of hazardous reactive oxygen species during the preparation and processing of meat is usually suppressed, first of all, with the help of
nitriteensuring the preservation of the desired color (Kudryashov J1.C., Baimishev R. Kh. // IB Myasnye tekhnologii, 2005, N 1, p. 20). Nitrites, binding in minced meat with hemoglobin, myoglobin, mitochondrial cytochrome oxidase and other heme proteins, block the reduction of intracellular oxygen to superoxide. In addition, nitrites have a beneficial bactericidal effect. That is why the question of increasing the maximum permissible norm for the addition of nitrites from 7.5 mg% to 12.5 mg% (Kudryashov J1.C., Baimishev R. Kh., Ibid.) And even up to 15 mg% is being actively discussed.
However, nitrites, chemical preservatives, synthetic antioxidants and stabilizers are far from harmless. Getting into the human body with food, they block the functioning of many enzymes and heme proteins, leading to a number of diseases, including cancer. Nitrites, chemical preservatives and phosphates in small quantities, it would seem, are not too toxic, but once they enter the body, as already mentioned, they inevitably work as "time mines". This gradually leads to loss of health and many serious illnesses.
It should be noted that a single dose of sodium nitrite of only 1 gram for a person is fatal... But the average consumer of sausages gets a double dose every year!
The widespread use of various phosphates as additives, used mainly to enhance the binding of water (to increase the weight of the product) and to maintain the desired pH, has the disadvantage that excess phosphates are inhibitors of mitochondrial succinate dehydrogenase (A.Leninger Biochemistry. M., Mir, 1974 p. . 190) and, in addition, directly catalyze the formation of free radicals induced by ions of ferrous iron (Roshchupkin D.I. et al. In collection: Superweak glow in biology. M., MOIP. 1972. pp. 75-77). Excess phosphates interact in human cells with iron proteins and free iron ions. As a result, polymer-like iron-phosphate complexes are formed (Kulaev I. S. Inorganic polyphosphates. M .: Nauka, 1975). They serve as powerful prooxidants leading to lipid peroxidation. Moreover, it is especially dangerous for the consumer that the amount of lipid peroxides long before tangible rancidity in sausages can be so great that, getting into the body with food, they cause an avalanche of free radical chain reactions in human cells and cause great harm to health.
Nevertheless, the "nitrite-preservative-chemical" method of obtaining minced meat for the manufacture of sausages, involving processing with nitrites, chemical preservatives and phosphates, is classic and is widely used in meat processing plants (Rogov I.A. et al. General technology of meat and meat products. M .: Kolos, 2000).
Every year the number of food additives and the range of food products containing them increases. Today their number is more than 500. More than 500.
Let's talk about preservatives... These are substances that are used to prevent food spoilage caused by microorganisms. The growth of bacteria can be temporarily delayed by cooling or heating. But with the help of preservatives it can be done much more efficiently. When adding preservatives, products acquire very important qualities. They can be transported over long distances, stored and at the same time be sure that they will not deteriorate. At home, salt, sugar, vinegar are used as preservatives, but they completely change the taste of the product. Industrial preservatives practically do not modify the taste of the product.
But there are also disadvantages to using preservatives.Even the safest of these, benzoic and sorbic acids have undesirable properties. Sorbic acid, for example, can inhibit the enzyme systems of the human body, and benzoic acid is poorly tolerated by young children. There are no universal preservatives safe for humans that could protect a meat product from the development of bacteria in it.
There are preservatives with a wide spectrum of action, such as sulfur compounds. They inhibit the growth of molds, yeasts, aerobic and anaerobic bacteria. Therefore, they are widely used in the manufacture of products, despite their frank toxicity. It is believed that the human body copes well with the breakdown and removal of these harmful substances from the body. But this is if the body is healthy and the purification systems function normally in it, that is, the liver and kidneys. But according to the latest statistics, only 20% of people can be called absolutely healthy.
Over the past decades, in many countries of the world, the attention of food specialists has been drawn to
antibiotics as substances that can delay food spoilage. Used in small quantities, they approximately double the shelf life of food. This is very important when transporting meat or fish over long distances. Therefore, antibiotics are also used as preservatives, although their use can lead to the emergence of resistance of pathogenic bacteria. This, in turn, can cause an unwanted side effect in a person consuming foods with antibiotic preservatives. In addition, the use of antibiotics can cause a violation of the required ratio of microflora in the human intestine and, accordingly, a whole bunch of intestinal diseases associated with this.
The next group of food additives commonly used in the food industry
antioxidants... They protect food products from chemical destruction by stopping the self-oxidation reaction of food. If the oxidation reaction has taken place, then the product acquires an unpleasant odor, taste and is toxic.
A large group of additives is made up of substances that affect the consistency of the product. These include
Thickeners, Emulsifiers and Stabilizers... Thickeners are natural: gelatin, starch, pectin, alginic acid, agar, carrageenan and semi-synthetic: carboxymethylcellulose, modified starches. A number of hygiene problems arise when using these additives.
First, these substances often contain contaminants and are difficult to control. Secondly, they are all nonspecific sorbents, that is, they are capable of absorbing all sorts of substances, regardless of their usefulness or harmfulness. Therefore, their use can interfere with the absorption of minerals.
Among the emulsifiers, phosphates are especially unsafe, which bind water and therefore stabilize the consistency. In sausage production, sodium phosphate (E339) and pyrophosphates (E450) are widely used, because they increase the moisture-binding capacity of sausage meat. Excessive use of phosphate in food can lead to an imbalance in the body between phosphorus and calcium. Excessive consumption of phosphates is fraught with a deterioration in the absorption of calcium, which leads to the deposition of calcium and phosphorus in the kidneys and contributes to the development of osteoporosis.
The same food additive is often used for different purposes. For example, nitrites are used as fixatives for the color of meat products (they stabilize the red color of meat caused by the red color of myoglobin and hemoglobin), and at the same time they are preservatives and inhibit the growth of botulism bacilli (Apraksina, 2005). Without nitrite, sausages, sausages and ham would be gray.
Usually, manufacturers use several food additives at the same time.
Here is one of the typical examples of the use of additives in sausage
sausage production.
Raw materials:
- Pork p / f - 93%;
- Fatty pork - 7%.
The following auxiliary substances are used per 100 kg of raw materials:
- Salt - 2200 g;
- Sodium nitrite - 7.5 g;
- Phosphate complex - 500 g;
- Ground coriander - 130 g;
- Ground white (black) pepper - 130 g;
- Fresh garlic - 80 g.
Composition of the complex (Combination P2000 Art. 103719):

E621 - N a-glutamate
In addition, the additives contain spice extracts and dried glucose syrup.
The output of the finished product is 128%. Shelf life in natural casing at 6 ° C is 10 days.
Here's another example:
