The impact of chiral tebuconazole on the flavor and appearance of Merlot and Cabernet Sauvignon wines were systematically studied. Gas chromatog.-ion mobility spectrometry and headspace-solid phase microextraction coupled with gas chromatog. mass spectrometry qual. and quant. identified the flavor components, and a photog. colorimeter was used for color attribute anal. Tebuconazole enantiomers had different effects on the flavor and appearance of young wines, especially R-tebuconazole. The flavor differences were mainly manifested in fruity and floral characteristics of the wine due to changes in the concentrations of acids, alcs., and esters; R-tebuconazole alters the concentrations of key flavor compounds to the greatest extent. Tebuconazole treatment changes the color of young wines, with the final red shade of wine being control group > rac-tebuconazole â?S-tebuconazole > R-tebuconazole. Since chiral tebuconazole neg. alters wine, grapes treated with chiral pesticides should be subject to stricter quality control during processing. This study involved multiple reactions and reactants, such as Isopentyl hexanoate (cas: 2198-61-0SDS of cas: 2198-61-0).
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. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.SDS of cas: 2198-61-0
