Fatty acid composition of soft whey cheese
Статья научная
Due to the existing environmental and economic situation, there is a tendency to produce new food products with a balanced composition and beneficial properties for the human body. In this context, new groups of products are appearing on the market, whose composition and properties differ from the standards. The key factor for the nutritional and biological value of products is again the fatty acids, which consist of saturated and unsaturated acids. Saturated fatty acids are carbon chains with a number of 4 to 30 or more atoms, found mainly in animal fats. Their function is to saturate the body with energy. Excessive saturation with fatty acids leads to a disturbance in fat metabolism and an increase in blood cholesterol levels. Unsaturated fatty acids are part of the components of cells and tissues, provide growth and metabolism, as well as the elasticity of blood vessels. The studied soft whey cheese was made from whey and is a new product of the dairy industry. In this work, the indicators of soft whey cheese such as proteins, fats, moisture, dry matter as well as fatty acid composition of the product are studied. From the analysis results, it is found that the product contains unsaturated fatty acids and its lipid composition has an optimal balance.

Functional whey-based drinks with grape pomace extract and fruit juice
Статья научная
Industrial waste leads to pollution and deterioration of the environment, as well as harming the living population and animals. Whey, being a by-product of milk processing, is a source of protein and nitrogenous compounds, carbohydrates, lipids, mineral supplements, vitamins, organic acids, enzymes and macro- and microelements. Amino acid content of whey is represented by amino acids of protein substances and free amino acids. The next valuable secondary raw material is grape pomace, which is practically not processed and becomes a factor of anthropogenic load, polluting the environment. Grape pomace has a rich chemical composition, especially a large number of phenolic compounds, which have antioxidant properties. Currently, there is a significant increase in the production and consumption of soft drinks with various additives, the composition of which is replete with unnecessary colors and flavors. The aim of the work is to use milk whey for the development of technology of drinks of functional purpose, which will directly increase the efficiency of its processing, as a secondary raw material in industrial production, as well as serve the purpose of improving the environmental situation in places where milk processing plants are located. In particular, the creation of functional drinks on the basis of milk whey with the addition of grape pomace, fruit juices and pectin, will enrich the milk drink with a complex of biologically active substances, trace elements, antioxidants, vitamins. Using organoleptic and physico-chemical parameters, two technologies of functional drinks based on milk whey with 25% Husein Black grape pomace extract, in the first 25% cherry and in the second 25% peach juices were developed. The first formulation demonstrated noteworthy macro- and microelement content, including calcium (12.10%), sodium (5.04%), magnesium (1.60%), phosphorus (7.31%), and potassium (24.61%). Similarly, the second formulation exhibited significant macro- and microelement composition, including calcium (9.50%), sodium (4.28%), magnesium (1.33%), phosphorus (6.37%), and potassium (21.91%). All microbiological indicators meet the requirements of GOST and indicate the absence of pathogenic microflora, which is one of the indicators of guaranteed sanitary well-being of the proposed products.
