Introduction. Studies have been conducted to determine the effect of adding chitosan to a malted meat product with mechanically separated poultry meat. Materials and methods. It is studied the technology of sausages with adding to the composition of poultry meat mechanically, serum protein concentrate, soy protein hydrated protein, animal protein, serum protein and developed protein-mineral carbohydrate supplement. Determination of amino acid composition was conducted in accordance with the method of ion exchange chromatography. Results and discussion. Boiled sausage with a proteinmineral-hydrocarbon additive has higher consumer properties compared to control samples. The moisture content of minced meat which has been added to the chitosan, namely the soy protein, animal protein, serum protein, and protein-mineral-hydrocarbon additi. increases by 10-15%, which enables to increase the yield of the finished product and plan the product properties after the completion of the technological stages of production. The addition of protein-mineral-hydrocarbon additi.in the amount of 10% in hydrated state positively affects the technological properties, it provides support for moisture, fat during the heat treatment process, which is important when used in the technology of boiled smoked products. Cooked sausages has a balanced amino acid composition compared to control. In cooked sausages it is observed higher levels of valine (0.8%), lysine (by 0.91%), methionine (at 0.10%), threonine (at 0.54%), alanine (at 0.54%), aspartic acid (to 0.65%) and glycine (at 0.59%)in comparing with the control sample. Conclusions. Chitosan when interacting with any animal protein increases the moisture content of the finished product 10-15%. Boiled sausage with mechanically separated poultry meat and protein-mineral-hydrocarbon additi has a wellbalanced composition, it has high consumer properties and can be attributed to complete nutrition by content of essential amino acids.
In the article, there were reviewed and conducted a comparative analysis of the amino acid composition of dietary supplements (animal protein, whey protein concentrate) and developed complex protein-mineral-carbohydrate additive using animal protein from natural pig meat, milk whey, chitosan, calcium chloride. The parameters of amino acid balance were set in order to determine the possibility of using secondary raw material as an additive to minced meat and target products. Results of the biological value of the developed protein-mineral-carbohydrate additive confirm the expediency of its use in the technology of meat products, as a valuable ingredient for the equivalent replacement of meat raw material. Received data suggest that the essential amino acids in PMCA are fairly balanced, utilitarian (rational) factor of amino acid composition of the protein corresponds to the degree of protein use by organism in relation to the required physiologically normal.
The research is dedicated to the development of recipes of cooked sausages and their diversification through including in the recipes poultry meat, and by-products of processing meat and milk. The meat products most affordable and popular with the Ukrainian people are selected for the study: cooked sausages and poultry meat wieners. The main components of the recipes are: red poultry meat, mechanically deboned poultry meat, medium-fat pork. In the recipes of the products developed, 10 % of the basic raw material was replaced with a hydrated protein-carbohydrate-mineral supplement. According to its physico-chemical characteristics, the protein-carbohydrate-mineral supplement in the technology of cooked sausage products allows us to get ready-made products with excellent quality parameters. It has been established that adding protein-carbohydrate-mineral supplement to the formulation significantly effects on the physico-chemical, functional, and technological parameters and biological value of meat products. The experimental data obtained show that the moisture content of the fresh stuffing for the sausages Kuryacha and the wieners Videnski is by 0.9 and 1.7%, respectively, higher than that in the control samples. The water-binding power in the fresh stuffing of the control samples is by 5% lower than in the test samples. In the finished product, the moisture-holding capacity is higher in the test samples (by 5.9% in the sausages Kuryacha, by 3.8% in the wieners Videnski). The study has shown that the amino acid score difference coefficient (AASDC) in the control sample of cooked sausage was by 11.2% higher than in the sample of the cooked sausage Kuryacha. In the control sausages, it was 13.0% higher than in the Videnski wieners. The developed cooked sausage products with the protein-carbohydrate-mineral supplement can be introduced into production as functional products with improved biological value.
