[Objective] To explore the effect of mixed yeasts on the waste lees liquor quality of Nongxiangxing Baijiu. [Method] The two yeast strains Z8Y-15 and S633Y-28-1 isolated from Nongxiangxing Baijiu brewing environment were inoculated in distillers’ grains and fermented for 40 days in pits. Then the contents of main components and aroma flavor-producing substances in fermented grains were detected. [Result] The result showed that the saccharifying power of mixture by two different yeast stains are more effective than a single tested stain or blank control group (P<0.01), along with the average alc. production was 8460.27 mg/L, which was 35.88% higher than that of the control group. These characteristics significantly improved the yield of wine. Meanwhile, the mixed yeasts could significantly reduce the contents of n-butanol and benzyl alc. in the waste distiller’s grains (P<0.05), increase the contents of isoamyl hexanoate (P<0.05), β-phenylethanol and Et butyrate (P<0.01). Thus the waste lees liquor body could change to be milder, and the flavor of waste lees liquor was more harmonious. [Conclusion] This study may shed light on the prospect of mixed yeasts in the future waste lees liquor production This study involved multiple reactions and reactants, such as Isopentyl hexanoate (cas: 2198-61-0Product Details of 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, including apples, durians, pears, bananas, pineapples, and strawberries. 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.Product Details of 2198-61-0
