Abstract

The invention belongs to the technical field of extraction of effective components of plants, and particularly discloses an extraction process of tea bran. The extraction method of the tea bran comprises the steps of enzymolysis of the tea bran, extraction and separation of effective components, purification of tea polysaccharide and tea saponin, and the like. According to the process, the tea polysaccharide and the tea saponin in the tea bran can be efficiently extracted, and the extraction efficiency and the purity of the tea saponin and the tea polysaccharide in the tea bran are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of extraction of plant effective components, and in particular relates to an extraction process of tea bran. Background technique [0002] Tea bran is tea seed cake, also called tea dry, which is the residue cake of camellia oleifera seed after oil extraction. Tea bran contains tea saponin, protein, oil content, natural tea polyphenols, and is a natural cleaning product. [0003] Tea saponin is also called tea saponin, tea saponin, a class of saponins. Studies have found that tea seed saponin has hemolysis and fish poisoning, anti-insect and bactericidal effects, anti-osmosis and anti-inflammation, phlegm and cough, analgesic, anti-cancer and other pharmacological functions. Tea seed saponin is also an excellent natural nonionic surfactant with strong foaming, emulsifying, dispersing, and moisturizing effects. The tea seed meal left after the oil camellia seed is pressed contains 10% to 14% tea saponin. T...
