Sunflower proteins, due to their high nutritional and biological value and wide distribution in the Russian Federation, are promising raw material for the production of food protein products for use in therapeutic and preventive and infant nutrition. In this regard, when choosing sunflower varieties, special requirements are put forward to them: a sufficiently high protein content and a high proportion of the kernel in the seeds, a balanced amino acid composition, compliance of safety indicators with the standards of technical regulations. VNIIFАТs conducts long-term research on the development of technology for protein concentrate and sunflower seed isolate. In cooperation with VIR, scientific work devoted to the selection of sunflower varieties that allow to obtain protein products with optimal properties is carried out. Functional properties, nutrient composition and physico-chemical parameters of sunflower protein concentrate have been studied. It is shown that sunflower protein is not inferior in its properties and biological value to soy protein concentrates presented on the Russian market. Therefore, it can be recommended as a protein and functional additive in therapeutic preventive and baby food products.
