The aroma components were extracted from mengding yellow bud by solid phase microextraction, and aroma composition of three samples were analyzed by gas chromatog.-mass spectrum (GC-MS), at the same time, sensory evaluation method was used to evaluate aroma characteristics of mengding yellow tea, in order to understand aroma composition of mengding yellow tea and anal. the influence between aroma composition and sensual aroma characteristics. The results showed that 90, 80, 96 components were identified from sample 1, sample 2, sample 3, which resp. accounted for 82.69%, 90.03%, 89.25% of the total peak area of the aroma components, various kinds of aroma components of mengding yellow tea, such as aldehydes, hydrocarbons, ketones, alcs. had more types of compounds and had high relative contents, the number of acids was few and the relative contents of acids was low, the relative contents of esters was lower, but there was little difference between the number of esters and ketones. The main components of three samples were 尾-flower cypressene, germacrene-D, caryophyllene, linalool, phytol, etc. Combined with the results of sensory evaluation from three samples, characteristics of mengding yellow tea was high sweet, faint scent and sweet smell. Mengding yellow tea compared with other tea, aroma components were close to green tea and oolong tea, and aroma quality with green tea scent and oolong tea flavor. It was concluded that mengding yellow tea had rich aroma components and sensual aroma characteristic was better, composition of aroma components had a certain influence on aroma characteristics. The study provided some theor. reference basis for the production and procession of mengding yellow tea. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Computed Properties of C15H22O2).
2-Ethylhexyl benzoate (cas: 5444-75-7) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Computed Properties of C15H22O2
