融合魏斯氏菌接种时序对黄酒酿造特性及挥发性风味成分的影响
Effect of inoculation timing of Weissella confusa AR1038 on brewing characteristics and volatile flavor compounds in Huangjiu
摘要
Abstract
Lactic acid bacteria play a crucial role in the flavor quality of Huangjiu.This study investigated the impact of different in-oculation timings of Weissella confusa AR1038 as an adjunct fermentation agent(D2:early fermentation,D5:mid-fermentation,D9:late fermentation)on the physicochemical properties and volatile flavor compounds of Huangjiu.Results showed that the inoculation timing had no significant effect on amino acid nitrogen and ethanol,but delayed inoculation significantly reduced the consumption rate of reducing sugars and the total acid content.GC-MS analysis revealed that the inoculation timing significantly affected the accumulation of alcohols and esters.Delayed inoculation of AR1038 promoted the synthesis of fatty acid ethyl esters,especially when inoculated on day 2(D2),which resulted in the highest content of fatty acid ethyl esters.Principal component analysis(PCA)indicated that delayed inoculation al-tered the flavor profile of Huangjiu,with similar flavor characteristics observed in the D5 and D9 groups.Caprylic acid ethyl ester,hep-tanoic acid ethyl ester,and hexanoic acid ethyl ester were identified as key flavor compounds in Huangjiu by analyzing odor activity value(OAV),with the D2 group exhibiting significantly higher levels of these three esters.In conclusion,appropriately adjusting the inocula-tion timing of W.confusa could effectively improve the flavor quality of Huangjiu,with a 2-day delayed inoculation being the optimal strate-gy.This study provides new insights into improving Huangjiu brewing techniques and flavor regulation.关键词
