Abstract

The invention belongs to fish product technology field, particularly a jewelfish oil microcapsule and the preparation method thereof. The jewfish is extracted and refined to obtain refined fish oil which is rich in Omega-3 polyunsaturated fatty acids and particularly DHA, then the refined fish oil is coated by compound film materials based on modified starch, and is dried by spray to obtain the microcapsule which is milky-white powder with good water-solubility, and can be used to prepare dietary supplements, food additives, etc.

Description

Contents of the invention [0001] The invention belongs to the technical field of fish products, and in particular relates to gemstone fish oil products and a preparation method. Background technique [0002] Scortum barcoo (Scortum barcoo) English name is Jade Perch. Australia's prestigious freshwater fish. In 2002, Zhejiang Modern Fishery Demonstration Park introduced jewel fish from the natural waters of Australia and successfully carried out artificial breeding. Gemfish has the characteristics of fast growth, strong disease resistance, high meat yield and high nutritional value. It was first evolved from seawater fish, so it not only maintains the tenderness of freshwater fish, but also has the unique deliciousness of seawater fish. The shape of the jewel fish is very attractive, the body color is silver and bright, and there are several black shiny oval plaques on the side of the body, just like black gems inlaid on the surface of the fish body, so it is called "jewel ...
