Abstract

An edible oil containing proportionally fatty acid composed of saturated fatty acid, mono-unsaturated-fatty acid and poly-unsaturated-fatty acid is prepared through enzyme-catalytic synthesis reaction between the plant oil rich in N6-series poly-unsaturated-fatty acid and the plant oil rich in N3-series one.

Description

technical field [0001] The invention belongs to an edible oil, in particular to an edible oil with coordinated ratio of fatty acid produced by biological enzyme catalysis and a production method thereof. Background technique [0002] N3 and N6 series polyunsaturated fatty acids are essential fatty acids for the human body and have important physiological functions. The ratio of N3 and N6 series polyunsaturated fatty acids also has an important impact on the immune function of the body. But at the same time, when the essential N3 and N6 series polyunsaturated fatty acids are too high, they are vulnerable to free radicals, and their carbon chains are oxidized and cracked to generate aldehydes, ketones and epoxides, which lead to changes in cell membranes and lipoproteins. Fatty acids have an appropriate ratio. Regarding the proportion of saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids, the most authoritative recommended value in the world is...
