摘要:

本研究旨在对黄酒糟发酵饲料的制备进行发酵工艺优化。通过单因素试验,以小肽和乳酸为主要发酵产物,确定黄酒糟发酵的最佳料水比、菌种接种量、菌种接种比例、发酵时间,并通过3因素3水平正交试验探究料水比、菌种接种量、发酵时间等发酵参数对黄酒糟发酵产物中小肽和乳酸含量的影响。单因素试验结果显示,添加5%的糖蜜可显著提高小肽含量,最佳工艺为料水比1∶0.4、菌种接种量1.0%、菌种接种比例1∶1∶1、发酵时间6 d;正交试验结果显示,在料水比1∶0.4、菌种接种量1.5%、发酵时间5 d的发酵条件下小肽含量最高,为119.11 mg·g-1,乳酸含量为0.53 g·kg-1。本研究获得最佳黄酒糟发酵工艺为:黄酒糟80%、麸皮20%、糖蜜5%、料水比1∶0.4、菌种接种量1.5%、菌种接种比例1∶1∶1、发酵时间5 d。

Abstract:

This study aims to optimize the fermentation process for preparing fermented feed from Huangjiu lees. Through single-factor experiments, using small peptides and lactic acid as primary fermentation products, the optimal feed-to-water ratio, microbial inoculum volume, microbial inoculum ratio, and fermentation time were determined. A three-factor three-level orthogonal experiment was conducted to investigate the effects of feed-to-water ratio, microbial inoculum volume, and fermentation time on small peptide and lactic acid contents in fermented products. The results of single-factor analysis showed that adding 5% molasses significantly enhanced small peptide contents, with optimal parameters being feed-to-water ratio of 1∶0.4, microbial inoculum volume of 1.0%, microbial inoculum ratio of 1∶1∶1, and fermentation time for 6 d. The orthogonal experiment demonstrated that the highest small peptide content of 119.11 mg·g-1 and lactic acid content of 0.53 g·kg-1 were achieved under feed-to-water ratio of 1∶0.4, microbial inoculum volume of 1.5%, and fermentation time for 5 d. The optimized fermentation process was determined as 80% Huangjiu lees, 20% wheat bran, 5% molasses, feed-to-water ratio of 1∶0.4, microbial inoculum volume of 1.5%, microbial inoculum ratio of 1∶1∶1, and fermentation time for 5 d.
