Modeling of fatty acid composition for dressing bases

Abstract

To date, a number of authoritative studies have proved the fact that sufficient consumption of polyunsaturated fatty acids (PUFA), such as omega-3 and omega-6 fatty acids, is not so important in nutrition as their certain ratio. This indicates the need to create fat and oil products with a given fatty acid composition. One of the ways to create such products is a simple technological technique – blending vegetable oils. This study was carried out precisely to achieve this goal. To develop a blend of vegetable oils with an optimal fatty acid composition, widespread and affordable vegetable oils in Russia were selected - unrefined sunflower and linseed oil. Their chemical composition was studied, the result showed the physiological inferiority of oils for humans. The composition of the blend of vegetable oils that provide the necessary ratio of ɷ-6 and ɷ-3 fatty acids for human health was calculated by the method of linear programming. The accordance of the obtained blend composition to the calculated values was determined by the method of gas-liquid chromatography. The resulting blend can be recommended as a basis for fat and oil products, in particular for creating dressing. The blend will make it possible to enrich the product with essential PUFA in a ratio of 4:1 and improve its qualitative and quantitative characteristics. The proposed blend of vegetable oils meets the requirements of GOST 31755/2012 and TR CU 024/2011 in terms of quality and safety indicators. Based on the research carried out, the developed dressing may have prospects in the market: in addition to an optimized fatty acid composition based on modern nutritional concepts, the cost of dressing is 5.7% lower than the price of an analogue.
