Abstract

The invention relates to a method for extracting anthocyanidin by using a compound enzyme, and a compound enzyme preparation thereof. The compound enzyme preparation disclosed by the invention comprises the following components of 7-15 wt% of cellulase, 7-15 wt% of hemicellulase, 7-15 wt% of a protease and 55-79% of pectinase. The method for extracting anthocyanidin by using the compound enzyme comprises the following steps of (1) preparing fresh fruit pulp, and adjusting a solid liquid ratio with water; (2) stirring the fruit pulp obtained from the steps (1) in a sealed container at a low speed, controlling a temperature within 40-60 DEG C and a pH value within 3-6, adding the above compound enzyme preparation, and enzymatic hydrolyzing for 1-8 hours, wherein the usage amount of the compound enzyme is 1 mg / g-3 mg / g; (3) removing fruit residues from the fruit pulp after enzymatic hydrolysis is finished to obtain clear fruit juice; and (4) refining the clear fruit juice by chromatography, and spray-drying to obtain an anthocyanidin product.

Description

technical field [0001] The invention relates to a method for extracting anthocyanins, in particular to a method for extracting anthocyanins with a compound enzyme and a compound enzyme preparation thereof. Background technique [0002] Anthocyanidin (Anthocyanidin), also known as anthocyanin, is a kind of water-soluble natural pigment widely present in plants in nature after it is combined with carbohydrates by glycosidic bonds. It is a biological substance with a special molecular structure. Flavonoids, which mainly exist in the form of anthocyanins in plants, are internationally recognized as the most effective natural antioxidants for eliminating free radicals in the human body. They have very strong biological activity and good absorption, and are 100% biologically effective to the human body , It can be detected in the blood 20 minutes after taking it. [0003] Anthocyanins can nourish the skin and enhance skin immunity. It can not only prevent the early generation of ...
