Abstract

The invention relates to a compound enzyme preparation for fermentation of pu'er tea, which is formed by compounding 10% to 20% of cellulase, 10% to 20% of pectinase, 5% to 15% of polyphenol oxidase, 5% to 10% of glucose oxidase, 5% to 10% glucoamylase, 5% to 10% xylanase, 5% to 10% of beta-glucanase, 5% to 10% of beta-mannase, 5% to 10% of tannase, 5% to 10% of acidic protease, 5% to 10% of lipase, 1% to 5% of alpha-amylase and 1% to 5% of phytase. By the aid of coordination of the enzyme system, polysaccharide and other substances in tea including cellulose and hemicellulose can be effectively decomposed, so that various physiochemical substances in cells can be dissolved. Meanwhile, oxidation and condensation of tea polyphenol, decomposition of protein, amino acid and carbonhydrate, a series of reactions of various products including polymerization and condensation and the like are accelerated and promoted.

Description

technical field [0001] The invention belongs to the technical field of tea processing, and in particular relates to a compound enzyme preparation for promoting the fermentation of Pu'er tea and its application. Background technique [0002] Modern Pu-erh tea is made of sun-dried green tea with fresh leaves of Yunnan big-leaf species that have been cleaned, hand-kneaded, and sun-dried. Aging, and finally through drying and other processing processes to form its unique quality of aging. Because Pu'er tea has many health functions such as digestion and greasy, weight loss and caries prevention, blood fat reduction, cholesterol reduction, bacterial growth inhibition, and cancer prevention, it is dubbed "slimming tea", "slim tea" and "longevity tea" abroad. At the same time, there is a great demand in Southeast Asia, Japan, Germany, the United States and other countries, as well as my country's Hong Kong and Taiwan regions. [0003] The heat and humidity during the fermenting pr...
