In this study, the volatile flavor components of different brands of preserved Lao-Xiang-Huang from the Chaoshan area were analyzed based on gas chromatog.-ion mobility spectrometry GC-IMS. A total of 9 types and 70 species were detected, including 8 esters (6%閳?2%), 14 aldehydes (10%閳?4%), 12 alcs. (13%閳?7%), 3 ketones (3%閳?%), 23 terpenoids (49%閳?2%), 6 acids (1%閳?%), 3 furans (2%閳?%), 1 thiazole (0.4%閳?.5%) and 1 pyrazine (0.6%閳?.6%). Through the calculation and anal. of relative activity value (ROAV), the key volatile flavor contributors of (ROAV>1) were obtained, including geraniol, citronellol, linalool, 1,8-cineole-M, 1,8-cineole-D, myrcene-M, methional, 3-methylbutanal, 3-methylbutanol, propanal, Me 2-methylbutanoate, 1-phenylethanol and nonanal. Among them, methional contributed the most to the flavor of the preserved Lao-Xiang-Huang. Principal component anal. (PCA) can effectively distinguish the samples of different brands. Partial least squares discriminant anal. (PLS-DA) combined with one-way ANOVA was used to screen 15 marker volatile compounds (VIP>1). GC-IMS can distinguish different brands of preserved Lao-Xiang-Huang, and allow rapid anal. of the differences in volatile compounds, thereby providing a reference for qual. and quant. research on the characteristic flavor components of preserved Lao-Xiang-Huang. In the experiment, the researchers used many compounds, for example, Methyl2-methylbutyrate (cas: 868-57-5Synthetic Route of C6H12O2).
Methyl2-methylbutyrate (cas: 868-57-5) 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. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Synthetic Route of C6H12O2
