摘要
为改善枣酒的品质,丰富枣酒香气,生产出酒体绵软适口,醇厚香浓的板枣果酒.本文采用单因素实验、神经网络和遗传算法优化发酵工艺,并通过体外消化实验对其发酵前后在胃肠道中的消化特性和抗氧化活性进行研究.结果表明,板枣酒的最佳辅料为山楂,最优发酵条件为:山楂与板枣的比例为1∶2.96(w/w),发酵温度29℃,浸提温度 45℃,感官评分为 81.66分.体外消化结果表明:板枣发酵酒总酚含量、DPPH自由基清除率和ABTS+自由基清除率在胃消化结束后分别提升了 16.19%、22.15%和 13.09%,在肠消化结束后提升了 42.06%、22.31%和85.80%.本研究为板枣发酵酒产品的开发和工业化生产提供了参考.
Abstract
To improve the quality of jujube wine,enrich the aroma of jujube wine,and produce a soft and palatable,mellow and fragrant jujube fruit wine,the single factor experiments,neural networks,and genetic algorithms were used to optimize the fermentation process,and in vitro digestion experiments were conducted to study the digestive characteristics and antioxidant activity of banzao jujube juice and banzao fermented wine in the gastrointestinal tract.The results showed that the best ingredient was hawthorn for jujube wine production.The optimal fermentation conditions of jujube wine were the ratio of hawthorn to jujube was 1∶2.96,fermentation temperature 29℃,extraction temperature 45℃.Under the optimal conditions,the sensory score of the jujube wine was 81.66.The results of in vitro digestion showed that the total phenol content,DPPH free radical scavenging rate,and ABTS+ free radical scavenging rate of jujube wine increased by 16.19％,22.15％,and 13.09％after the end of gastric digestion,respectively,and increased by 42.06％,22.31％,and 85.80％after the end of intestinal digestion.The study would provide a reference for the development and industrial production of jujube wine products.
