Abstract
A method for enzymatically preparing a n-3 polyunsaturated fatty acid diacylglycerol using oil rich in n-3 polyunsaturated fatty acid as raw material to prepare diacylglycerol oil with selective enzymatic hydrolysis. Before the enzymatic reaction, the raw materials are homogenized to improve the catalytic efficiency of lipase in the hydrolysis and achieve the purpose of reducing the reaction time and the addition amount of lipase. As a result, the cost of industrial diacylglycerol preparation is reduced, ultimately reducing the cost of industrial diacylglycerol preparation. Therefore, the present invention provides an effective, mild and low-cost enzymatic method for preparing diacylglycerol rich in n-3 polyunsaturated fatty acids, which has a promising potential for industrial application.
