Abstract:

In order to find out the feasibility of industrialization of ultrasound treatment used in late fermentation process of Chinese rice wine, 30 L fermentor based on ultrasonic circulation was used for Chinese rice wine brewing. This paper studied the effect of ultrasonic assisted on the routine physics and chemistry index, such as alcohol content, total acid content and reducing sugar content during late fermentation process of Chinese rice wine. It also analyzed and compared the effect of ultrasonic assisted on the flavor substance, such as amino acids, organic acids, esters, aldehydes and higher alcohols. The results showed that there was no significant difference between the alcohol content of ultrasonic circulation treated samples and control samples at the end of fermentation. The study found that the contents of amino acid and organic acid of Chinese rice wine treated by ultrasonic circulation was higher than that of the control samples. While, the content of higher alcohols of Chinese rice wine treated by ultrasonic circulation was significant lower than that of the control samples. The results of clustering analysis indicated that ultrasonic circulation could enable the post-fermentation of Chinese rice wine to fermentation in advance. This research result revealed the feasibility of shortening fermentation cycle of Chinese rice wine by ultrasonic circulation.

Key words: ultrasound, Chinese rice wine, brew cycle, volatile flavor, clustering analysis

摘要:

为探索超声波辅助黄酒发酵的工业化可行性,采用30 L循环式超声波发酵罐进行黄酒酿造,研究超声波辅助对黄酒后酵过程中酒精度、总酸、还原糖等常规理 化指标的影响,分析比较了超声波辅助对黄酒后酵过程中氨基酸、有机酸、酯类物质、醛类物质、高级醇等风味物质的影响。结果表明30 L循环式超声波辅助 对黄酒后酵过程中酒精度的变化影响不明显,且黄酒醪液氨基酸和酯类总含量都高于未经超声处理的样品,而黄酒发酵醪液高级醇含量均显著低于未经超声处 理的样品;经聚类分析表明循环超声处理的方式能使黄酒后发酵提前达到发酵终点。该结果揭示了循环超声波辅助黄酒发酵,缩短酿造周期的可行性。
