摘要： The present invention discloses a method for preparation of vitamin and carotenoid powder; the vitamin and carotenoid powder comprises vitamin, carotenoid microcapsule and physical gel protection film covered on the surface of the vitamin and carotenoid microcapsule; the physical gel protection film is made from super-molecular system; the super-molecular system comprises the following constituents of parts in weight: vegetable oil: 6-30 parts; gel: 0.5-3 parts and antioxidant: 0.5-3 parts. The hot super-molecular solution is sprayed on the surface of cold vitamin and carotenoid microcapsule during preparation to form a specific 3D network structure that is used to bind the liquefied vegetable oil to form a physical gel protection film; the physical gel protection film has improved product storage stability as well as the its stability for application in feedstuff, food and health care products.
