Carrier material with dextran shell core structure and its preparation and application

摘要

The present invention discloses a carrier material having a dextran shell core structure and its preparation and application and belongs to the technical field of modern food processing. The present invention employs spherical hyperbranched water-soluble starch particles as a raw material, adopts an enzyme graft chain extension process, and forms the surface of a water-soluble dextran molecule by modifying it into a solid shell structure having a dense crystal structure, It is formed into a carrier material having a dextran shell core structure with "nuclear hollow amorphous foam, outer layer crystalline state". The spherical hyperbranched water-soluble starch particles used in the present invention have a wide source of raw materials, are not limited by the place of origin and season, have simple steps, are easy to operate, control reaction conditions, and are cost-effective. Relatively low and environmentally friendly, the products prepared according to the present invention can effectively protect, transport and release functional nutritional ingredients, and are useful in many areas such as food, pharmaceuticals and everyday chemicals. The market prospects are very promising and the economic benefits are broad.
