The present disclosure provides a preparation and application of high-activity and high-safetyselenoprotein standard sample. The standard sample of theselenoprotein prepared by the present disclosure has the advantages of extremely low heavy metal content, less ash, high protein content, high total selenium content, high organic selenium ratio of up to 99.9%, high biological activity, high safety and so on; the organic selenium is mainly in form of selenocysteine/selenocystine and accounts for more than 90% of the total selenium content, and is expected to make up for the shortage of selenoprotein standard samples on the market.

Preparation and application of high-activity and high-safety cardamine violifolia selenoprotein standard sample

The present invention discloses a microencapsulation method for improving stability of anthocyanin, a product therefrom and use thereof. A preparation method of anthocyanin microcapsules includes: (1) taking sodium alginate as a wall material, adding sodium alginate and calcium carbonate into water, and swelling for 1-2 h to obtain a wall material gel system; (2) taking anthocyanin prepared by a special process as a core material, and fully and uniformly mixing the wall material gel system with an anthocyanin solution to obtain a water phase; (3) mixing Span80 and vegetable oil to obtain an oil phase, mixing the water phase with the oil phase, and magnetically stirring for emulsifying to obtain a W/O emulsion; and (4) adjusting the pH of the W/O emulsion to be acidic, mixing the W/O emulsion with a salt buffer solution, standing for 1-2 h, and then separating the oil phase and the water phase.
