The study of influence of natural antioxidants on quality of peanut and linseed oil blends during their storage
Journal Title: Восточно-Европейский журнал передовых технологий - Year 2018, Vol 3, Issue 11
Abstract
<p>Influence of various natural antioxidants (oil extracts of sage and black currant leaves, garlic and hips) on in-storage quality of oils has been studied. Dynamics of the acid and peroxide numbers of fat of the developed oil samples was studied. Influence of natural antioxidants on preservation of polyunsaturated oleic, linoleic, linolenic fatty acids in peanut and linseed oil blends was established.</p><p>When developing blended oils with an optimal fatty acid composition, it is advisable to use linseed oil which is characterized by a high content of ω-3 fatty acids. Since polyunsaturated fatty acids have a high degree of oxidation and degradation, they are unstable. This causes certain difficulties both in production and storage of vegetable oils and solving the problem of improving the product quality.</p><p>It was established that the use of natural antioxidants affects preservation of quality of peanut and linseed blends, namely, organoleptic properties, acid and peroxide numbers of fat. It was proved that introduction of the studied oil extracts in an amount of 5 % increases the oxidation resistance of peanut and linseed oil blends by 1.2‒1.7 times.</p><p>It was shown that to evaluate the effect of plant extracts on quality of the developed blends, it is expedient to use the content of polyunsaturated fatty acids as the main criterion. It was established that natural antioxidants contribute to preservation of 69.0‒73.0 % of linoleic acid, 73.5‒78.9 % of oleic acid and up to 82 % of linolenic acid from the initial content in peanut and linseed oil blends. The ratio of polyunsaturated fatty acids ω-6:ω-3 inall samples remained at the level of ratio of these acids in fresh blends, namely 4:1.</p><p>The use of plant extracts in the formulations of peanut and linseed oil blends significantly slows down the processes of hydrolysis and self-oxidation which ensures in-storage preservation of consumer properties of new oils with an optimized fatty acid composition.</p>
