Problems solved by technology

[0004] In the current processing technology of golden camellia tea products, high-temperature curing is usually used to remove the green and astringent taste of the leaves. However, after the fresh leaves are greened, under the action of heat and humidity, the chlorophyll undergoes hydrolysis or demagnesification reaction, forming a dark olive green charred demagnesium. Dephytochlorophyll or pyropheophytin is unfavorable to the green color of golden camellia tea solid beverage
In addition, due to the high content of ester-type catechins and caffeine in the fresh leaves of Camellia chrysalis, the bitterness index of catechins is large, which will affect the taste of solid beverages of Camellia chrysalis
