Abstract

The invention provides a golden camellia white tea and a preparation method thereof. The preparation method includes the steps that branches and leaves obtained after tea pruning are subjected to withering and twisting, and then added to an immobilized column for fermentation treatment; then, the immobilized column is inoculated with the eurotium cristatum for fungal fermentation, the immobilized column after fungal fermentation is subjected to elution and then centrifugal treatment, the precipitate after centrifugation is dried at low temperature, and golden camellia powder is obtained; finally, the finished white tea product and the golden camellia powder are prepared into small squares, and the golden camellia white tea is obtained. The golden camellia white tea has the advantages that the probiotic composition of eurotium cristatum and the pharmacological effect of white tea are combined, and meanwhile raw liquid for black tea beverage processing can be produced, therefore, the utilization ratio of leaves obtained after tea pruning is greatly increased, and waste materials are turned into wealth. More importantly, due to the technological innovation, the varieties of tea products are expanded, the technological content of products is increased, the health care function of the tea is improved, and meanwhile, the economic value of products is increased.

Description

technical field [0001] The invention belongs to the field of tea processing, and in particular relates to a golden flower white tea and a preparation method thereof. Background technique [0002] The commonly known "Golden Flower" in Fuzhuan tea is actually the golden closed capsule of the coronoid fungus, which looks like Milan flower and has a golden color. More importantly, it can secrete polysaccharides, statins and other beneficial physiologically active substances, which can regulate the blood lipids and intestines and stomach of the human body. And S. coronis is widely distributed in nature, and it can grow and reproduce as long as there are suitable environmental conditions. Cai Zhengan et al. (2010) have also confirmed through experiments that S. coronis has no special requirements for host nutrition. However, the temperature and humidity requirements for the environment are more stringent. Wen Qiongying (1986) also obtained the conclusion that the optimum temperat...
