Embodiment 1

[0023] Commercially available high-purity EPA, DHA, DPA, AA, SDA, ALA, GLA, CNLA and CLA polyunsaturated fatty acids are used as raw materials and mixed in a certain proportion (EPA 18.60%, DHA 14.67%, DPA20.25%, AA8. 53%, SDA2.71%, ALA6.23%, GLA3.61%, CNLA 6.67% and CLA 9.46%, other fatty acids 9.24%). The mixed fatty acid and glycerol triacetate are mixed according to the molar ratio of 2.5:1, the immobilized lipase LipozymeRM (Novozymes company product) of 5% of the mass of the mixture is added, and they are placed in a constant temperature stirring reactor at 50-60°C together. The absolute pressure is below 200Pa, and the reaction time is 8h. After the oil phase of the reactant is recovered, it is separated and purified by molecular distillation. The molecular distillation temperature is 180-190°C, and the working absolute pressure of the molecular still is below 1Pa. Free fatty acids and other low boiling point components are removed to obtain polyunsaturated fatty acids ...

Abstract

The invention discloses a grease composition and a preparing method thereof. The general formula of the composition is I, fatty acid acyl groups R1 and R3 of sn-1(3) loci of triglyceride are polyunsaturated fatty acids with the carbon chain length of 18-22 carbon atoms, and a fatty acid acyl group R2 at a sn-2 locus is a middle-short-chain fatty acid. According to the grease composition and the preparing method thereof, through orienteering design on the molecular structure and fatty acid composition and position configuration of structural fat rich in polyunsaturated fatty acids, and via thesynergistic effect of the middle-short-chain fatty acid in intake and exertion of the physiological function on the PUFA, the absorption rate and bioavailability of the PUFA are increased. When the grease composition is used as a dietary supplement, the dietary composition and eating habit are not changed. The grease composition has more efficient functions of reducing blood fat and losing weight,and has higher oxidation stability.

Description

technical field [0001] The invention relates to an oil composition, in particular to an oil composition rich in unsaturated fatty acids and short- and medium-chain fatty acids. Background technique [0002] Polyunsaturated fatty acids (PUFA) generally refer to fatty acids containing two or more double bonds. A large number of studies have confirmed that polyunsaturated fatty acids are essential nutrients for human and animal growth and maintenance of normal metabolism and physiological activities. Moreover, in the diet, adequate intake of polyunsaturated fatty acids can also regulate and improve lipid metabolism in humans and animals, especially the functions of n-3 polyunsaturated fatty acids to lower blood fat and assist in lowering blood sugar. Some n-6 and n -9 polyunsaturated fatty acids have the function of losing weight. Common PUFAs that have special physiological functions on the human body mainly include eicosapentaenoic acid (EPA, n-3), docosahexaenoic acid (DHA...
