Organic nitrogen plays a significant role in the fermentation performance and production of esters and higher alcs. This study assessed the use of yeast protein hydrolyzate (YPH) as a nitrogen source for grape must fermentation In this study, we prepared an enzymic protein hydrolyzate using yeasts recovered from a previous fermentation of wine. Three treatments were performed. DAP supplementation was used as a control, while two YPH treatments were used. Low (LDH) and high degrees of hydrolysis (HDH), 3.5% and 10%, resp., were chosen. Gas chromatog. and principal component anal. indicated a significant pos. influence of YPH-supplementations on the production of esters and higher alcs. Significantly high concentrations of 3-methyl-1-penthanol, isoamyl alc., isobutanol, and 2-phenylethanol were observed Significant odorant activity was obtained for 3-methyl-1-pentanol and ethyl-2-hexenoate. The use of YPH as nitrogen supplementation is justified as a recycling yeasts technique by the increase in volatile compounds This study involved multiple reactions and reactants, such as Isopentyl hexanoate (cas: 2198-61-0Recommanded Product: 2198-61-0).
Isopentyl hexanoate (cas: 2198-61-0) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Recommanded Product: 2198-61-0
