Summary/Abstract: A source of valuable n-3 fatty acids, oils are derived from macadamia nuts, peanuts, red palm, sesame, rice, apricots, and safflower. The ratio of total polyunsaturated fatty acids to saturated Σ UFA/Σ SFA in the studied oils changed from 2.88 to 13.33. SFA saturated fatty acid content is the highest in the oil and red palm canola CPA (24.59%) and oil from rice (25.80%), while the lowest is in the safflower oil (6.98%), apricot (9.85%) and rape (7.30%). The ratio of fatty acids C18:3 (n-6) /C18:3 (n-3) for the tested oils is nutritionally beneficial for humans. Oleic acid, C18:1, the highest is for olive oil ca. 72–78% oil and safflower ca. 77%. Sesame oil contains at least 39%. To compare their susceptibility to oxidation of fats, the value relationships Σ C18:3 /C18:1 and C18:2 /Σ C18:3 can be used.
