Popis: The article characterizes the peanut (Arachis hypogaea) as an oilseed crop widely spread in the world. It describes its biological value as well as the chemical and fatty acid composition. The study proves the practical importance of developing and introducing new blended functional purpose oils for Ukrainian people. It has been shown that blended oils contain significant amounts of monounsaturated and polyunsaturated fatty acids. The use of blended oils will correct the deficiency of essential fatty acids in the diet of our country’s population. It has been pointed out how promising it is to create new types of blended oils, with a balanced fatty acid composition, by combining peanut and linseed oils. The article describes the characteristics of the new blended peanut-linseed oils with additives made from vegetable raw materials. The evaluated parameters are the quality and safety of the new blended peanut-linseed oils with a garlic extract, rosehip extract, sorrel leaf extract, and black currant leaf extract. The fatty acid composition of the fat in the new blended oils has been studied to determine their quality. The safety assessment of the new oils with the additives from vegetable raw materials has been determined by the content of pesticides (HCH-gamma isomer, heptachlor, and DDT), mycotoxins (aflotoxin B1 and zearalenone), toxic elements (lead, cadmium, arsenic, mercury, and zinc), iron, and radionuclides (cesium-137 and strontium-90). The results obtained confirm that the new blended oils are safe. The blended oils have a high biological value when the ratio of w-6 to w-3 fatty acids is 4.9:1, and the ratio of monounsaturated fatty acids to polyunsaturated fatty acids is 1:1, which meets the standards of healthy nutrition. In terms of chemical and radiation safety, the new oils do not exceed the maximum permissible concentrations, confirming the safety of the newly developed oils.
