Processing method of selenium-copper-rich green tea

Abstract

The invention discloses a processing method of selenium-copper-rich green tea, and belongs to the technical field of tea processing. The processing method of selenium-copper-rich green tea provided by the invention has the advantages that according to the growth characteristics of a tea tree, an organic selenium copper nutrient solution is fully supplemented in the growth period of the tea tree; after being harvested, tea leaves are subjected to a series of simple processing such as spread drying, water removing and fumigating, so that after the tea leaves are brewed; tea buds are upright; the effect that as one falls, another rises is achieved; the color and luster are emerald green; the fragrance is aromatic and durable; the soup color is clear and bright; the taste is fresh, cool and mellow; the leave bottom is tender green and complete; the ornamental value is realized; in addition, the organic selenium copper content is obvious; no any injury is caused on the human body; meanwhile, the effective ingredients of tea polyphenol, amino acid and theine in the tea leaves are remained to the great degree; the tea leaf quality is improved, so that the commodity property of the tea leaves is greatly improved.

Problems solved by technology

[0005] Tea is the most common health drink in daily life, but the levels of selenium and copper in tea processed by traditional methods are very low. In order to meet the health needs of many ordinary consumers, patent application No. 2007100291702 discloses "a selenium-enriched green tea And production method thereof " the selenium-enriched green tea of ​​this invention has good outward appearance luster, good mouthfeel, sweet taste, the selenium content in the tealeaves improves, but the selenium-enriched nutrient solution that adopts is selenium-containing inorganic salt such as: sodium selenite or selenic acid Sodium, although 80% of inorganic selenium is converted into organic selenium, but some inorganic selenium remains in the leaves of tea leaves. If things go on like this, it will cause excessive residual inorganic selenium, which will cause more serious damage to the human body
