Mixture of vegetable oils with balanced fatty acid Composition
Context. The study considered the issue of creating a mixture of oils with a balanced fatty-acid composition, namely the required ratio of ω-6 and ω-3 acids. To create a mixture of oils with a balanced fatty acid composition, an analysis of various vegetable oils was carried out to study the possibility of their use in providing the human body with polyunsaturated fatty acids by using a mixture with a balanced fatty acid composition.
Sunflower predominates in the Kazakh oilseeds market and in recent years flax has taken more and more stable positions and safflower is successfully cultivated in the southern regions. Safflower oil has a significant content of linoleic acid (over 78%), which is essential and is necessary to ensure the integrity of plasma membranes, growth and reproduction processes, skin and other organs.
The aim of the study is to obtain a mixture of vegetable oils with a balanced fatty acid composition.
As components of a mixture of vegetable oils with a balanced fatty acid composition, it is recommended to use sunflower, linseed and safflower oil, which are successfully produced in Kazakhstan.
The objects of research were sunflower, safflower, linseed oil and their mixtures in a ratio of 70:05:25; 75:05:20; 70:15:15. In vegetable oils and their mixtures, organoleptic parameters, fatty acid composition were determined on the CHROMOS GH-1000 gas chromatograph (Russia) with a flame ionization detector.
Results and conclusions. Studies of the fatty acid composition of the mixtures have found that the use of vegetable oils (sunflower, safflower, linseed) in an amount of 70:05:25 and 75:05:20 allows to obtain a product with an acid ratio of ω-6: ω-3 ≤ 5:1, which is more desirable to reduce the risk of many chronic diseases.
