Pungency is one of the most important mouthfeel characteristics that is primarily related to the sensory quality of distilled spirits. However, the chem. basis of pungency is still unclear. A set of Baijiu samples with different levels of pungency was characterized by sensory anal. and volatile compound analyses. Several esters, aldehydes, and acids significantly correlated with pungency. Et hexanoate, Et acetate, 3-methylbutyl hexanoate, acetaldehyde, acetal, and 3-methylbutanal were confirmed to be the strongest contributors to the pungency of Baijiu by the two-alternative forced-choice test. Sensory recombination testing further revealed that the contribution of esters to pungency was much higher than that of the aldehydes, and acid compounds at low concentrations suppress the pungency perception. In this study, the importance of esters in the pungency of distilled spirits is first reported. The results provide an instructive basis for further research into optimizing the quality of products. This study involved multiple reactions and reactants, such as Isopentyl hexanoate (cas: 2198-61-0Application In Synthesis of Isopentyl hexanoate).
Isopentyl hexanoate (cas: 2198-61-0) 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. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Application In Synthesis of Isopentyl hexanoate
