Abstract
Kazakhstan's market for producing minced meat semi-finished products is not sufficiently developed. At the same time, the demand for products of the “economy” segment is growing. Providing balanced recipes for semi-finished meat products, with a rational combination of raw materials of animal and vegetable origin, is a significant problem. Chopped meat cutlets with high nutritional and low energy value have been developed, which are not inferior in functional and technological properties and sensory characteristics to traditional products. Pork and wheat bread were excluded from the recipes, with a replacement for lamb or broiler chicken meat in combination with a protein-carbohydrate composition (PCC) of the composition: soy minced okara – chickpea flour – whey protein concentrate (WPC 80) in a ratio of 9:5:10, at 1:3 hydration. The rational share of the introduction of PCC into the recipe of cutlets was 25% for minced beef – the meat of broiler chickens and 20% for minced beef – lamb. The studied samples of PCC, control minced meat with pork and bread, and two modified minced meat recipes for cutlets have similar values of the mass ratio of water fractions at three stages of dehydration during heat treatment. PCC particles are evenly distributed between the muscle fibers in minced meat. It has been shown that the developed PCC can serve as a substitute for minced meat not only in terms of the balance of the amino acid composition of the total protein but also in terms of the percentage of moisture with different forms of communication with the product, influencing the microstructure and consistency of raw semi-finished products of the combined composition, the consistency and juiciness of fried cutlets. According to the developed recipes, the mass fraction of protein in cutlets increased from 13.8 to 19.1-19.8%; fat decreased from 12.6 to 9.5-9.7%.
