Abstract:

To explore the effects of scenting technologies on jasmine tea aroma quality, the aromatic constituents of jasmine tea of the orthodox and the isolated scenting process were determined and compared by using HS-SPME/GC-MS/RI method, and the sensory evaluation of the two kinds of processed tea was carried out, in order to lay a foundation for the exploration of new jasmine tea processing technology. The results show that the 6 main aromatic constituents of jasmine tea are linalool, benzyl acetate, α-farnesene, (Z)-3-hexenyl benzoate, methyl anthranilate and indole, and the aromatic characteristics are basically formed after the 1st scenting process. There is little difference of the relative content of alkene during the orthodox and the isolated scenting process. Compared with that of the isolated scenting process, the relative content of alcohols during the orthodox scenting process is 7.75% lower. The relative contents of esters and nitrogenous compounds are both lower during the isolated scenting process. The relative content of ketone is relatively low. According to the sensory evaluation, the aroma score of orthodox scenting tea is higher than that of isolated scenting tea. In conclusion, under the same manufacturing condition, the aroma quality of jasmine tea processed by orthodox scenting is superior to that of isolated scenting.
