Problems solved by technology

[0006] In the selection of microcapsule wall materials, traditional wall materials such as gelatin, sodium caseinate, gum arabic, etc. are widely used, but the content of microcapsule products is often low, which is not suitable for the preparation of high content products
In addition, the fluidity and water solubility of protein wall materials are relatively poor, especially not conducive to the diffusion of cold water, and the release is poor, which greatly affects the use effect of the product

Abstract

The invention relates to high-content krill oil microcapsules and a preparation technology thereof. The technology comprises the following steps: by taking krill oil and microporous starch as core materials, adding a small amount of xanthan gum into oil phase; and by taking chitosan oligosaccharide and oxidized starch as wall materials, mixing an oil-phase antioxidant, a water-phase antioxidant, an emulsifier, a dispersant and the like in proportion to prepare micro-emulsion, and performing spray drying to prepare krill oil microcapsule powder. The obtained krill oil microcapsule product contains 10-30 percent of phosphatide and keeps biological activity, improves the light-heat stability, acid-alkali stability and the like of krill oil, has good solubility in cold water, and is relatively easy to process, transport and store, safety, fluidity and water solubility are greatly improved, the application range of krill oil is enlarged, and the krill oil is an excellent health-food raw material, and is widely applied to dairy products, beverages, health-care products, baking, tablets and the like. The yield of the krill oil microcapsule powder prepared according to the technology is high, the phosphatide content of the product is high, and the technology is suitable for mass preparation of krill oil microcapsule powder and realizes continuous large-scale production.

Description

technical field [0001] The invention relates to the production technical field of krill oil microcapsules, in particular to a high-content krill oil microcapsule and a preparation process thereof. Background technique [0002] Antarctic krill is one of the organisms with the highest protein content that has been found. The protein content is more than 50%, and it also contains extremely rich amino acids and vitamin A necessary for human tissues. It is a natural health gift from nature to human beings. Foods contain functions that cannot be replaced by other foods. [0003] The phospholipid-bound Omega-3 (including EPA and DHA) contained in Antarctic krill oil is easier to absorb than the triglyceride-type Omega-3 in fish oil, and is an effective source of DHA and EPA. Plus, krill oil contains a natural antioxidant, astaxanthin. In addition to preventing cardiovascular diseases, astaxanthin also has a protective effect on the retina and central nervous system. The health f...
