    THE EFFECT OF PLANT PROTEINS ON THE FORMATION OF STRUCTURAL AND RHEOLOGICAL PROPERTIES OF NOUGAT
    (2021) L. Gordiienko, V. Tolstykh, K Avetisian
    This paper considers the problem of increasing  the nutritional value of whipped confectionery such as nougat by using hemp- based and soya-based protein-containing ingredients. The  main  tendencies of obtaining new types of food based on plant proteins with complete amino acid composition are described. The paper presents information on cultivating and using hemp and soya both in Ukraine and in the world, and suggests how products of their processing can be applied to improve the quality and increase the biological value of confectionery. It has been investigated what effect protein-containing ingredients obtained from hemp and soya have on the structural properties of foam in the technology of whipped confectionery such as nougat. It has been  established  that increasing the amount of plant protein additives leads to a decrease in the foaming ability, but the stability of protein foams increases. Adding 10% of protein-containing hemp additives increases the foam stability by 6%, while protein-containing soya additives increase it by 5%. The paper presents the results of studying the structural and rheological properties of nougat mass with protein-containing plant additives in the amount 2.5–10% of the weight of sugar. It has been determined that adding protein-containing hemp and soya ingredients increases the viscosity and plastic strength of the products and stabilises their structure. The effect of different amounts of nuts on the kinetics of nougat crystallisation has been studied. It is recommended to add 5% of hemp and 7.5% of soya protein-containing additives instead of sugar during the whipping of nougat mass, because it reduces the whipping time and has a positive effect on structure formation. The recommended  amount of roasted pistachio kernels in the samples suggested is 25–35% of the total weight of nougat, with the resting time 30–60 minutes and the moulding temperature 50–55°C. The nutritional value of the new products with protein-containing hemp and soya  ingredients and nuts has been calculated. It has been noted that nougat has been enriched with protein, unsaturated  fatty acids, and minerals (potassium, calcium, magnesium, phosphorus).
