Abstract

The invention provides a processing technology for novel white tea and belongs to the technical field of tea leaf processing. According to the white tea treated through the technology provided by the invention, pathogenic bacteria on the surfaces of the tea leaves can be fully killed and pesticides on the tea leaves can be neutralized through treatment by edible acids, and part of cell walls of the tea leaves are broken, so that nutrients of the white tea are more easily soaked. By spraying a decomposing enzyme to the tea leaves which are treated by the edible acids, the cell walls of the tea leaves are further decomposed, and nutrients such as beta-galacturonic acid, glucose, cellobiose and the like are generated. Through quick cooling in four different stages, the phenol ammonia ratio of the content of the tea leaves can be reduced, the proportion of tea polyphenol showing astringency is reduced, the proportion of free state amino acid compounds showing fresh and smooth characteristics is improved, and meanwhile, volatilization of aromatic substances which are easily volatilized in the white tea such as trans-3-hexenyl alcohol, benzyl alcohol and the like, so that the integral quality of the tea leaves is improved.

Description

technical field [0001] The invention belongs to the technical field of tea processing, and relates to a novel white tea processing technology. Background technique [0002] White tea is unique in region, natural in craftsmanship and unique in efficacy. Traditional Chinese medicine proves that white tea is cool in nature, reduces heat and fire, relieves heat and detoxifies, and has the effect of curing diseases. Especially with the in-depth research on white tea in European and American countries in recent years , white tea has the following effects: [0003] 1. Anti-cancer, anti-cancer, heatstroke prevention, detoxification, and toothache treatment. White tea has the lowest free radical content, the highest flavonoid content, and the average amino acid content is higher than other teas. Radiation, anti-tumor, increase the interferon secretion of human immune cells by 5 times, etc. White tea extract has a preventive effect on the growth of bacteria that cause staphylococcus ...
