Oolong tea is famous for its natural floral fragrance, and it is also the top grade for its high-quality, rich and special floral or nectar fragrance. After research, hydrocarbons (mainly alkenes), alcohols, esters, ketones, aldehydes, acids, phenols, heterooxygen compounds and nitrogen-containing compounds affect the aroma of oolong tea. richer. The aromatic substance content of oolong tea accounts for about 0.053% of the total dry matter of tea leaves, which is significantly higher than that of other teas.
In addition, the difference in fresh leaf varieties, tenderness, origin and oolong tea processing methods of tea trees also affects the formation of aroma. The fresh-leaf variety depends on the physiological and biochemical characteristics of the tea variety. The tenderness of fresh leaves is required to have a certain degree of maturity, and is different from red and green tea. Variety, tenderness and origin are the prerequisites for tea aroma, and the later processing technology is a necessary means for the formation of tea aroma. First, in the process of processing, light energy causes strong biochemical effects in the withering process. Second, the oolong tea shaking process undergoes enzymatic oxidation and hydrolysis, and then low-temperature and long-term heat treatment in the oolong tea drying process. These production processes have an impact on the aroma of oolong tea. formation plays an important role.
Oolong tea is not enough to be withering, shaking, fixation, and the distribution and transformation of the components of grassy are not enough, so the finished tea has grassy. Not withering or withering process too much, the temperature of oolong tea shaking is high, the fermentation is excessive, and the aroma of the finished tea is low. If the fermentation is insufficient, the tea fixation is excessive, the initial drying temperature is too low, and the aroma is often cloudy and dull. The fresh leaves are coarse and old, the base of aromatic substances is poor, and the drying and fixation are insufficient, making the tea coarse and old. If the baking temperature is too high, a large amount of aromatic substances will volatilize and decompose, and the fixation effect will be weakened. If the temperature of the frying pan is too high and the time is too long, it is easy to produce coke gas. There is furnace smoke when hojicha is adsorbed, and smoke is generated after the tea leaves are adsorbed.
