Studying the possibility of using an pea protein isolate in the meat and vegetable culinary technology production

The purpose of research is to study the possibility of using pea protein isolate in the production technology of a meat and vegetable culinary product of a functional orientation. Tasks: to study the physicochemical and biochemical parameters of pea protein isolate; to develop the technology of a meat and vegetable culinary product with the addition of pea protein isolate; to determine the quality indicators of the finished product and develop a production control program. Objects: commercially produced pea protein isolate, a laboratory sample of a meat and vegetable product prepared according to a standard recipe and technological scheme (control), prototype soufflé samples with the addition of 5 %, 10 and 15 % pea protein isolate to the mass of poultry meat. At the first stage of the research, the physicochemical parameters and biochemical composition of the pea protein isolate were determined. It has been established that the test sample contains an easily soluble and easily digestible protein base (60.6±0.02 %) and special easily soluble carbohydrates (30.1±0.02 %), gluten, lactose and anti-food components are absent. The study of biochemical parameters allows us to conclude that the pea protein isolate contains 7 essential amino acids, as well as polyunsaturated fatty acids, the content of which is 2 times higher than the total content of saturated and monounsaturated fatty acids and is 66.5 and 33.4 %, respectively. The data obtained allow us to conclude that it is possible to use pea protein isolate in the technology for the production of functional foods. The technology of a meat and vegetable culinary product with the addition of pea protein isolate in the amount of 5% by weight of poultry meat has been developed and the quality indicators of the finished product have been determined. The results of the organoleptic evaluation indicate high quality indicators of the prototype. Physical and chemical indicators have the following values: humidity - 70.52 % (at a rate of 70.5 ± 2 %), the minimum allowable amount of soluble solids per 100 g - 17.92 %, pH is 6.9. Microbiological indicators are within acceptable limits. The determination of nutritional value indicators indicates an increase in the amount of protein compared to the control by 23.7 % and a decrease in fats and carbohydrates by 12.2 and 9.1 %. At the final stage of research, a production control program has been developed.
