Currently, great attention is being paid to the rational multipurpose use of food products in the development of food products. This work is aimed at creating blends of different types of oil based on vegetable and animal raw materials and studying their properties. The research is also aimed at obtaining blends of oils with various prophylactic properties. Blending of vegetable oil and rendered animal fat is considered one of the important resources of fat and oil production today. Blends based on vegetable oil are formulated, that makes it possible to simultaneously feed a person with various vegetable oils. Blends based on vegetable and animal oils are formulated to enable rational use of beef and poultry oils. The blend contains amaranth oil, which has a beneficial effect on the removal of antioxidants from the human body. To determine the content of vitamins and the density of oils, calculations were used according to the additivity rule, bypassing the expense of funds for laboratory instruments. In the process of blending, an oil product was obtained, which is the basis for spreads.
