Elaboration of vegetable oils’ mixtures with a balanced fatty acid composition

Abstract

Optimized mixtures of vegetable oils to ensure a balanced composition of ω-3 and ω-6 acids were developed. The analysis of the raw material base for oil industry of the Republic of Belarus were done. Oils of nine species were chosen for investigation, 5 of which are the traditional raw material for the production of vegetable oils, and 4 are alternative sources, the use of which is possible as enriching components of mixtures of vegetable oils. Imbalance of fatty acid composition of almost all vegetable oils was shown, which proves the need for development of oils mixtures. Different mixtures of vegetable oils that provide the necessary health ratio of polyunsaturated fatty acid were calculated by the method of linear programming formulations. GLC defined co-responsible resulting compositions blends calculated values. It was found that the proposal-conjugated ble nds No. 1 and No. 2 can be rec-ommended for daily and preventive feeding of population as PUFA ratio is 10 : 1, which fully meets the needs of the human body in the essential fatty acids. Sa mples No. 3 and No. 4 content the co-ratio of 5 : 1 because flaxseed oil rich in ω-3 fatty acids, which is sufficient for a recomme ndation of the prod-uct as a therapeutic feeding. The proposed blends of vegetable oils, are fully compliant with technical regulations on quality and safety of these products. In addition, the proposed mixtures of vegetable oils are undoubtedly due to the economic feasibility of the maximum using of the domestic raw canola, flax and blueberries, which fully corresponds to the direction of impor t substitution in the Republic of Belarus.
