Abstract

The invention provides a method for simultaneously separating starch, anthocyanin and total polyphenol from dioscorea alata.L. The method comprises the following steps of (1) beating and acid leaching, (2) flocculation, (3) separation of the starch, (4) macropores resin adsorption and elution, (5) separation of the anthocyanin and (6) separation of the total polyphenol. The method can simultaneously obtain the three high-content natural components of the dioscorea alata.L, and achieves the comprehensive utilization of a dioscorea alata.L resource; the method has the advantages that the processis simple, the operability is strong, the equipment requirements are low, the production cost is low, and the method is suitable for the industrial production.

Description

technical field [0001] The invention relates to a method for separating effective components of purple ginseng potato, in particular to a method for simultaneously separating starch, anthocyanin and total polyphenols from purple ginseng potato. Background technique [0002] Purple ginseng potato (Dioscorea alata.L), also known as purple yam, big potato, red-cut potato, sweet potato, foot plate potato, is a twining vine of the genus Dioscorea in the family Dioscorea, and its hypertrophic or cylindrical roots are edible . The skin of purple ginseng potato is purple-brown, the meat is smooth and bright in color, it contains more vitamins and trace elements than ordinary ginseng potatoes, and also contains a lot of protein, starch, polysaccharides, minerals, polyphenols, especially anthocyanins , deeply loved by the people. Anthocyanins have various pharmacological effects such as anti-aging, anti-oxidation, anti-tumor, prevention and treatment of cardiovascular and cerebrovas...
