Currently, there is an increase in the use of preparations from collagen-containing raw materials in the production of meat products. The high functional and technological properties of such preparations make it possible to significantly improve the rheological properties of food products, as well as organoleptic indicators, and enrich meat products with dietary fibers. The aim of this study was to study the effect of an emulsion of 5% protein hydrolysate and 1% purslane powder on herodietic boiled sausages for the elderly. The results showed that the experimental samples of boiled sausages contained 15.44% protein, 6.6% fat, 4.2% carbohydrates and 71.1% moisture; this shows that boiled sausage with the addition of protein hydrolysate contains optimal chemical composition for dietary nutrition, a certain moisture index confirms the excellent consistency of boiled sausage. The change in the peroxide number was studied for 7 days. The results showed that the peroxide number did not change significantly from 2.0 meq/kg to 4.6 meq/kg. Thus, the addition of purslane with antioxidant properties helps to slow down the oxidation of fats and thereby increases the shelf life of boiled herodietic sausage. The results of the study of color characteristics showed stable color formation, which was influenced by an emulsion of collagen and purslane. It was found that products using emulsions from collagen-containing raw materials are characterized by a higher concentration of tyrosine due to the action of proteolytic enzymes (pepsin and trypsin)—from 728.1 mcg/mL (during the first three hours of hydrolysis) to 392.5 mcg/mL (during 6 h of hydrolysis)—which indicates a higher degree of protein digestibility these products. Thus, the addition of an emulsion of 5% protein hydrolysate and 1% purslane powder can be recommended for the production of boiled sausages with improved nutritional and taste properties.

A recipe for cooked sausages of the herodietic direction using protein hydrolysate in the amount of 3%, 5%, and 7% of the mass of raw materials is proposed. The recipe is based on "Beef Sausage". Organoleptic evaluation of the prototypes showed that when protein hydrolysate was added in an amount of 7%, a specific taste characteristic of by-products was present in the prototype. Based on the sensory evaluation results, it was decided to continue the study of samples with the addition of 3% and 5% protein hydrolysate. The results of the study of the physicochemical parameters of the prototypes with the addition of protein hydrolysate 3% and 5%, showed the values of the mass fraction of protein 16.65% and 19.29%, fat 9.85% and 12.25%, carbohydrates 2.85% and 3.07% respectively, indicating an increase in the amount of protein and a decrease in the proportion of fat compared to the control sample. A significant increase in the content of such essential amino acids as lysine and valine and interchangeable amino acids as arginine, glycine, and serine in the test samples confirms that the protein hydrolysate introduced into the prototype is rich and well-balanced in amino acid composition. To study the effect of protein hydrolysate on the quality of meat products, the moisture binding capacity was determined, which was 3% and 5% in the experimental samples with the addition of protein hydrolysate - 75.62% and 79.13%, which is 3.4% and 8.2% higher than that of the control sample, respectively. The sample with the addition of 5% hydrolysate (80.01) has the greatest moisture-retaining ability, which is 9% higher than that of the sample with 3% hydrolysate and 15.8% higher than the control indicator. The study results of the fat-holding capacity in the samples also showed positive dynamics. [ABSTRACT FROM AUTHOR]
