The volatile compounds found in melons (Cucumis melo L.) obtained from three cultivars [Jiashi (JS), Xizhoumi17 (XZM) and Minqin (MQ)] were comprehensively analyzed by gas chromatog.-olfactometry (GC-O), gas chromatog.-mass spectrometry (GC-MS), and GC-flame photometric detection (GC-FPD). The result showed that 46, 45 and 69 volatile compounds were detected in XZM, JS and MQ samples by GC-MS, resp. Besides, 6, 8 and 9 sulfur compounds were detected by GC-FPD, resp. Di-Me sulfide, 1-propanethiol, 3-mercapto-3methylbutanol, 3-methyl-2-buten-1-thiol were detected for the first time in melon. 25 key aroma compounds were identified in MQ muskmelon by omission tests, among which (Z)-6-nonenal, (Z)-6-nonen-1-ol, 3-methylbutanal, 2-methylbutyl acetate, hexanal and Me thioacetate were particularly important. The interaction between three aroma compounds containing nine-carbon straight-chain structure and five thioesters in MQ muskmelon was studied by comparing their olfactory threshold and OAV values. Among the 18 binary mixtures, 8 mixtures showed a synergistic effect, 2 mixtures presented an additive effect, 2 mixtures showed no interaction, 6 mixtures exhibited a masking effect. There is a synergistic effect between (Z)-6-nonenal, (Z)-6-nonen-1-ol and (E, Z)-3,6-nonadien-1-ol, the aroma intensity of the mixture can be predicted by modified vector model. This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0Synthetic Route of C8H16O2).
Methyl heptanoate (cas: 106-73-0) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. 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.Synthetic Route of C8H16O2
