Abstract
Along with the development of public awareness of the issue of environmental protection, an increase in the consumption of plant products as a substitute for animal products is observed. Due to the diversified amino acid composition and sensory properties, plant equivalents of animal proteins are sought. Extracts, isolates and hydrolysates of vegetable proteins are commonly used in food products, they can supplement the diet of vegans and obtain the right texture and sensory experience of food products. Oilseeds are an alternative source of vegetable protein. Due to the content of all amino acids, these essential proteins could potentially be used in food, but are now rarely used as food ingredients. A good example of a source of such a valuable protein is canola (Brassica napus). The waste after canola oil pressing of rapeseed, in the form of oil cake or meal, are currently used mainly as animal feed. Nowadays, there are few reports on the use of this material as a food source on a commercial scale, despite the fact that it contains nutritionally complete proteins adequate to meet human requirements for essential amino acids. In this study, attempts were made to optimize the process of extracting proteins from meal after pressing canola oil. The protein content in the obtained product was assessed depending on the process temperature (from 25 to 55°C), process time (30 to 120 min) and composition of the extraction solution (meal content in solution). The results allowed to determine the optimal conditions for protein extraction from rapeseed meal: 300g of meal content in 1l of solution, extraction time – 90 minutes, temperature – 55 °C.
