| Abstract | Objective: To determine the fatty acid composition of soybean oil depending on technological processing. Methods: Laboratory, analytical, expert, chemical, and statistical methods. Results: It was established that in both unrefined and refined soybean oil, the highest content was of polyunsaturated fatty acids (PUFAs) – 52.1–57.3%. Linoleic acid was the predominant fatty acid in the PUFA fraction – 50.3–50.9%. The content of linolenic acid was 1.24% in unrefined and 7.0% in refined oil. The monounsaturated fatty acid (MUFA) fraction accounted for 22.8–28.9%, with oleic acid being the main component – 22.6–28.5%. The saturated fatty acid (SFA) fraction was the lowest – 14.8–15.2%, with palmitic acid as the main component – 10.2–10.6%. The content of other fatty acids was minimal. In hydrogenated oil, the SFA fraction was dominant – 94.0%, with stearic acid being the highest – 83.1%, while palmitic acid accounted for only 10.0%. The PUFA content was only 0.38%. One hundred grams of unrefined and refined soybean oil provide 521–573% of the daily PUFA requirement. The integral score for SFA was 49–51% and for MUFA 38–48%, whereas in hydrogenated oil, the integral score for SFA was 305% and for MUFA and PUFA only 3%. Conclusions: In both unrefined and refined soybean oil, the highest content was of PUFAs – 52.1–57.3%, with linoleic acid as the main component – 50.3–50.9%. Linolenic acid content was 1.24% in unrefined and 7.0% in refined oil. MUFAs accounted for 22.8–28.9%, mainly oleic acid – 22.6–28.5%. SFAs were the lowest – 14.8–15.2%, mainly palmitic acid – 10.2–10.6%. Hydrogenated oil was dominated by SFAs – 94.0%, mainly stearic acid – 83.1%, and palmitic acid – 10.0%. | ||
