Abstract

The invention discloses a krill oil microcapsual powder and its preparation method. The preparation method comprises steps of: preparation of an oil phase solution and an aqueous phase solution, mixing and emulsification of the two solutions, homogenizing, drying and the like. The krill oil microcapsual powder is prepared from the following raw materials of: by weight, 0.001-90% of krill oil, 0.5-90% of sodium caseinate and 0-99% of a filler. In addition, 0.001-10 wt% of an oil phase antioxidant, 0.001-5 wt% of an aqueous phase antioxidant, 0.001-5 wt% of an aqueous stabilizer and 0.001-5 wt% of an anti-caking agent can also be added. The krill oil microcapsual powder has high content of the encapsuled krill oil and has good stability and fluidity. After rehydration, krill oil can be dispersed into water completely in the form of particles (nm); and krill oil is stable if stored for a long time, and has no phenomenon such as floating oil, precipitation, adhesion to bottles and the like. therefore, the application range of krill oil is broadened, and krill oil is applied to fields such as dry mixing, drinks, dairy products, bakery, tablets and the like.

Description

technical field [0001] The invention relates to a preparation method of krill oil microcapsule powder, in particular to a preparation method of krill oil microcapsule powder rich in high phospholipid content with high embedding rate. Background technique [0002] Antarctic krill is the largest single biological resource on the earth. The latest data released by the United Nations Food and Agriculture Organization shows that the total biomass of Antarctic krill is about 125-725 million tons, and the annual catchable amount is about 4-6 million tons. The most important potential fishery resource for the world's pelagic fisheries. Because Antarctic krill lives in cold waters, it is rich in active substances such as Omega-3 polyunsaturated fatty acids represented by eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are precious health care products. raw materials. Its unsaturated fatty acid is currently the only molecular structure in nature that combines omega...
