《Characterization of the key aroma compounds and microorganisms during the manufacturing process of Fu brick tea》 was written by Li, Qin; Li, Yongdi; Luo, Yu; Xiao, Lizheng; Wang, Kunbo; Huang, Jianan; Liu, Zhonghua.

Aroma is one of the most important criteria of tea quality, but the dynamic changes of aroma profile during the manufacturing process, and the chem. basis of characteristic aroma in Fu brick tea remain largely unknown. In this study, a total of 72 volatiles were identified and quantified, only the esters content increased sharply during the process. Sensory quant. description anal. revealed that the ‘green’ attribute was dominated in the early processing stage, and the ‘fungal flower’, ‘flower’, ‘mint’ and ‘woody’ attributes became the major contributors to the aroma character in the later processing stages. Indicated by partial least-squares anal., the linalool, acetophenone, and Me salicylate were identified as key volatiles contributors to the ‘fungal flower’, ‘flower’, and ‘mint’ attributes, the cedrol contributed to ‘woody’ attribute, and twelve alcs. and aldehydes were related to ‘green’ attribute. Besides, bidirectional orthogonal partial least squares anal. revealed that six fungal genera Aspergillus, Candida, Debaryomyces, Penicillium, Unclassified_k_Fungi, Unclassified_o_Saccharomycetales were identified as core functional microorganisms link to the metabolism of volatiles. Taken together, these findings provide new insights into Fu brick tea aroma profile variation and increase our understanding of the formation mechanism of the characteristic aroma during the manufacturing process. The experimental process involved the reaction of Methyl Salicylate(cas: 119-36-8Category: esters-buliding-blocks)
Methyl Salicylate(cas: 119-36-8) has been used: as a component of clarifying solution for treating Mongolian gerbil cochlea intact for immunofluorescence analysis, as a plant elicitor to test its effect on reducing the whitefly population from tomato plants.Category: esters-buliding-blocks
