This article provides a brief analysis of the composition of the nutrient media used for the cultivation of bifidobacteria. Objects of the research are strains of bifidobacteria of different types from RUE “Institute for Meat and Dairy Industry” Centralized industrial collection of lactic acid bacteria strains. The growth of bifidobacteria of different types in three nutrient media was analyzed at the initial stage of the study. As a result of data analysis the optimal nutrient medium, which has a stable structure, which provides a fairly high growth of microorganisms and makes it possible to evaluate the impact of injected components on the development of bifidobacteria was selected. The assessment of the impact of different concentrations of yeast extract on the growth of bifidobacteria depending on their species is given. It has been established that for the majority of the strains studied the maximal response was observed when 0.5% yeast extract was injected to the medium. A twofold increase of this component (to 1% ) contributed to further stimulation of cultures growth, but did not cause a proportional increase in the optical density for the majority of the strains tested. The exception was the strain 2630 B-O (B.longum), for which this parameter remained at the same level as in the medium containing 0.5% yeast extract. For B.bifidum species, the reaction to the appending of yeast extract to the nutrient media and to the increase of its concentration was specific for each strain.

The samples of sheep milk from lakaune breed are studied. It is found that sheep milk is characterized by a high content of solids, proteins, fat, has a high acidity and density, which shows its biological value. Compared to cow and goat milk, proteins of sheep milk contain more essential amino acids, fat-acids C4 - C12.
The article deals with the results of the study of effect of antimicrobial agents on lactic acid and propionic bacteria of starter population of cheese during its ripening and storage. It is established, that potassium nitrate causes some stimulation, while lysozyme suppresses the development of lactic acid bacteria at the initial stages of cheese ripening. However, further use of them doesn’t lead to credible changes in the dynamics of the development of lactic acid and propionic bacteria and doesn’t cause any changes in the taste and consistence of cheese during its ripening in comparison with the control variant. The addition of nisin (1 g for 100 liters) leads to the inhibition of acidity growth, coagulation failures, bad synaeresis of the substance, and reduction of the quantity of lactic acid bacteria in cheese at the initial stages of cheese ripening, therefore it is not appropriate to use it.

The article presents the results of the work on the creation of the assortment of canned vegetable-meat with reduced phenylalanine, designed to supply patients with phenylketonuria.
It is found that 100 g of canned product contains: protein - no more than 1.6 g, phenylalanine - no more than 150 mg, which corresponds to the requirements of products with reduced content of individual amino acids.
As a result of medical and biological assessment of canned vegetable-meat with reduced phenylalanine made in experimental conditions of SSI "Institute of Physiology of National Academy of Sciences of Belarus" it was found that canned foods are safe for life and health of mammals. The level of phenylalanine in the blood of the rats treated with canned vegetable-meat with reduced phenylalanine during 3, 7 and 14 days remained almost unchanged in comparison with the control group, whereas it increased 3–3.5 times for the animals treated with canned meat. The data obtained make it possible to recommend eating canned product with reduced phenylalanine for patients with phenylketonuria as well as healthy people in order to reduce weight.

In the shops of industrial and feed products of the enterprises of meat industry inedible raw animal materials are processed in dry fodder, included in the ration of agricultural animals, including birds. Depending on the material used different types of dry fodder and meal are obtained, as well as vegetable and animal feed. Simultaneously with manufacturing of some types of feed meal technical and feed fat are received. Such shops are the sources of the most intensive pollution of the atmosphere by unpleasantly smelling substances. This article offers an innovative technology of meat and bone meal production, which makes it possible to eliminate the leakage of bad-smelling substances in the atmosphere of the shop, to increase the degree of purification of the ventilation emissions, to recover heat energy, to increase production output, to reduce the burden on the sewer systems.
