The ester is generally a neutral colorless liquid. The ester generated by the fatty race and saturated alcohol has a fruit aroma, which can be dissolved in water, and it is also difficult to dissolve in water. Some ester's flash point is low and often burn. The steam can be absorbed by the respiratory tract, and the liquid ester can be absorbed by the skin. After absorption, it is dissolved in the plasma, and some of them are discharged through the lungs and kidneys. After some hydrolysis, turn into the normal metabolic process. In addition to a few of the ester compounds, most of them are highly toxic and highly toxicity, and most of them are micro -toxic to medium toxic categories, and many of them are non -toxic. There are 38 esters in the aroma groups of tea. Mainly: ① fatty ester: generated by alcohol and fat, such as ethyl acetate, hexyl hexyate. ② Aromatic ester: generated by alcohol and aromatic acid, such as Shun-3-hexylzyl. ③ Circin esters: generated by alcohol and cyclocar, such as jasmone hyacxide. The ester is generally neutral, which can be hydrolyzed and produces alcohol and acid. Low carbon numbers are usually fragrant liquids, and high carbon numbers are liquid and solids insoluble in water.
