Abstract

The invention discloses a method for preparing Cordyceps militaris flavochrome powder. The Cordyceps militaris flavochrome powder is prepared through subjecting Cordyceps militaris, which serves as a raw material, to enzymolysis by a specific compound enzyme, and then, carrying out extracting and drying. According to the method, by the step of carrying out enzymolysis on the Cordyceps militaris through the compound enzyme, the yield of Cordyceps militaris flavochrome can be increased greatly, and the obtained Cordyceps militaris flavochrome is good in stability, has relatively high physiological activity and is high in content of total flavonoids. The method disclosed by the invention is simple in step and easy in operation; and compared with the existing Cordyceps militaris flavochrome extraction methods, the method disclosed by the invention has the advantages of low cost, short time and high yield, thereby being applicable to popularization and application.

Description

technical field [0001] The invention relates to the field of preparation technology of yellow pigment powder, in particular to a method for extracting yellow pigment from Cordyceps militaris and making it into powder. Background technique [0002] Cordyceps militaris (Cordyceps militaris), also known as Cordyceps militaris, belongs to the genus Cordyceps genus of the Ascomycota subphylum Ergot. The orange-yellow color of Cordyceps militaris is caused by its own yellow pigment, which is a carotenoid. Most of the carotenoids discovered so far are fat-soluble carotenoids, which are not easily absorbed by the human body and some are unstable when exposed to light and heat. Cordyceps militaris yellow is a rare class of water-soluble carotenoids discovered so far. [0003] Carotenoids are a large class of pigments in the global ecosystem and are widely distributed in nature. As a precursor of vitamin A, carotenoids help to prevent and cure vitamin A deficiency. At the same time, ...
