Abstract

The present invention relates to a preparation method for a polyunsaturated fatty acid-calcium, primarily comprising directly reacting a polyunsaturated fatty acid material with a water-soluble calcium compound to obtain a polyunsaturated fatty acid-calcium salt. The present invention has a simple technical process, short reaction time, and high reaction yield. The produced polyunsaturated fatty acid-calcium product is of high quality, and relatively less byproducts and waste water are produced. The process is overall environmentally friendly and has small safety risks, and is suitable for scaled production.
