In order to evaluate the effects of yeast starter on the quality and flavor profile of Longyan dry white wine, pure fermentation and sequential fermentation of selected Torulaspora delbrueckii and selected Saccharomyces cerevisiae (VL2, DELTA, X5) were performed in industrial-scale fermentation of this work. Compared with pure fermentation, sequential fermentation improved the fermentative aroma concentrations, especially the treatment of T. delbrueckii/DELTA increased the content of Et butyrate, Et caprylate and Et decanoate, which may be related to a strong citrus fruity aroma. Principal component anal. revealed a significant difference in aromatic feature of co-fermentation of T. delbrueckii/DELTA and T. delbrueckii/VL2 from their resp. pure fermentation These may be related to amino acid metabolism and further affected the formation of volatile compounds according to correlation anal. Overall, sequential fermentation using DELTA and T. delbrueckii strengthened the aroma characteristics and improved the complex of wines. It will provide a new strategy to regulate the flavor and improve the quality of Longyan dry white wine. 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. 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. 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.Application In Synthesis of Isopentyl hexanoate
