METHOD FOR OBTAINING VEGETABLE OIL WITH GIVEN RATIO OF ESSENTIAL FATTY ACIDS

摘要

FIELD: food industry.;SUBSTANCE: invention relates to the fat and oil industry, in particular to a process for the production of vegetable oil with a predetermined ratio of essential fatty acids. Method includes determining the fatty acid composition of the initial oilseeds, initial calculation of the number of seeds of each species, seed batching according to the initial calculation, seed mixing, mixture pressing, oil filtration, determination of the fatty acid composition of the oil, carrying out an accurate calculation of the number of seeds of each species for obtaining oil with a given ratio of essential fatty acids obtained according to a certain system of equations, mixing seeds according to the specified calculation, pressing, filtration, determination of fatty acid composition and packing the obtained oil. Initial calculation of the number of seeds of each species is carried out using a system of linear equations , where m₁ is the weight of the first oil-containing raw material in the mixture, kg (g, t); is content of polyunsaturated ω-6 acids in the first oil-containing raw materials,%; M₁ is oil content of the first oil-containing raw materials, %; m₂ is the weight of the second oil-containing raw material in the mixture, kg (g, t); is content of polyunsaturated ω-6 acids in the second oil-containing raw material, %; M₂ is oil content of the second oil-containing raw material, %; is content of polyunsaturated ω-3 acids in the first oil-containing raw material, %; is content of polyunsaturated ω-3 acids in the second oil-containing raw material, %; y is the required ratio of polyunsaturated fatty acids ω-6:ω-3. Specified calculation is carried out immediately after the initial calculation.;EFFECT: use of the invention will enable to obtain vegetable oils of a specified fatty acid composition of high quality.;1 cl, 3 tbl, 1 ex
