Investigation of the fatty acid composition of vegetable oils

Abstract

Emulsion fat products are a promising direction for the enrichment of unsaturated groups with fatty acids. This is possible by introducing rarely used types of vegetable oils into the formulations of these products. Due to the fact that the fatty acid composition of vegetable oils differs depending on the properties of the raw materials from which it is produced, there is a need for its analysis for a more accurate formulation of the emulsion product. As a result of the conducted studies, 17.3% saturated fatty acids and 83% unsaturated, respectively, were found in pumpkin oil. Pumpkin oil is rich in monounsaturated fatty acids, such as oleic acid (47%). Chromatographic study of the fatty acid composition showed that ginger oil contains 9.7% saturated fatty acids and about 90.3% unsaturated acids. Linolenic acid turned out to be the most in the oil (32.6%). It was found that the sample of black cumin oil contains 21.9% saturated and 78.1% unsaturated fatty acids. Most of all in linoleic acid oil (about 56.9%). The studied oils are rich in unsaturated fatty acids and can be used as additives in mayonnaise sauces to saturate certain groups with unsaturated fatty acids, each of the studied oils will saturate a certain group. Pumpkin oil is a source of monounsaturated fatty acids (oleic fatty acid), ginger oil is a source of omega–3 fatty acids (linolenic fatty acid), black cumin oil is a source of omega–6 fatty acids (linoleic fatty acid).
