Abstract

The invention discloses a green tea processing technology. The technology comprises the steps of tea leaf collection, fresh leaf spreading cooling, enzyme deactivating, shaping, drying, sterilizing and fragrance enhancing, screening, and packaging and warehousing. The enzyme deactivating step comprises steam enzyme deactivating and roller enzyme deactivating, and a segmented quick cooling technology is adopted after completing the steam enzyme deactivating and roller enzyme deactivating to carry out quick cooling, so the phenol / ammonia ratio of the content in tea leaves is reduced, the proportion of tea polyphenol having bitter taste is reduced, the proportion content of free amino acid compounds for showing fresh and refreshing characteristics is improved, volatilization of cis-3-hexen-1-ol, benzyl alcohol and other volatile tea leaf fragrant substances is reduced, and the color, the smell and the taste of finished tea are improved to reach high levels.

Description

technical field [0001] The invention belongs to the technical field of tea processing, and in particular relates to a green tea processing technology. Background technique [0002] As a beverage, tea has been spread to various ethnic minority areas in Northwest my country since the Tang Dynasty, and has become a necessity for the local people's life. China is the origin of tea tree. However, China’s contribution to mankind in the tea industry is mainly due to the fact that it was the first to discover and utilize the plant tea, and develop it into a splendid and unique tea in my country, the East and even the whole world. culture. As recorded in the historical records of our country, before drinking tea, "the ancients drank water in summer and soup in winter", and always quenched their thirst with warm soup and water. Drinking tea has changed people's bad habit of drinking raw water and greatly improved people's health. As for tea in Europe and the United States, it is co...
