摘　　要：为探讨微生物辅助发酵香草兰豆荚加工过程中主要风味成分的变化。该文采用在香草兰豆荚加工过程中喷淋从香草兰豆荚上筛选得到微生物的辅助发酵方法,对比喷淋微生物辅助发酵香草兰加工与传统加工过程中香草兰主要风味成分的变化。结果表明:传统加工处理(C1)过程中香兰素葡萄糖苷含量呈逐渐减少趋势,从杀青前香兰素葡萄糖苷含量8.85%到陈化阶段香兰素葡萄糖苷含量0.74%,下降了91.63%;香兰素含量呈增长趋势,从杀青前香兰素含量0.42%到陈化阶段香兰素含量2.05%,升高了79.51%;喷菌处理(M1)中喷菌量6 m L的发酵豆荚香兰素葡萄糖苷含量为0.67%、香兰素含量最高为2.68%。C1、M1喷菌量6 mL的发酵豆荚上分别检测出26、29种挥发性成分,其中相对含量较高的成分有香兰素、愈创木酚、乙酸和糠醛等物质。电子鼻分析表明C1与M1喷菌量6 mL处理的发酵豆荚风味成分有明显差别。微生物辅助发酵在香兰素含量、挥发性成分上都优于传统加工,研究结果为微生物辅助香草兰豆荚初加工提供了一定的数据支撑。To explore the changes in the main flavor components during the processing of vanilla beans through microbial assisted fermentation,this study adopted an assisted fermentation method of spraying microorganisms selected from vanilla beans during the processing of vanilla beans,and compared its changes in the main flavor components of vanilla with the traditional processing method.The results showed:during the traditional processing(C1),the content of glucovanillin tended to decrease gradually,from 8.85%before blanching to 0.74%during the aging stage,a decrease of 91.63%,while the content of vanillin showed an increasing trend,from 0.42%before blanching to 2.05%during the aging stage,an increase of 79.51%.During the spraying bacteria processing(M1),the fermented beans with spraying volume of 6 mL had a glucovanillin content of 0.67%and the highest vanillin content of 2.68%.A total of 26 and 29 volatile aroma components were detected on the fermented beans of C1 and M1 with spraying volume of 6 mL,respectively,with higher content components including vanillin,2-methoxyphenol,acetic acid and furfural,among others.Electronic nose analysis indicated that significant differences in the volatile components of fermented beans processed by C1 and M1 with spraying volume of 6 mL.Microbial assisted fermentation is superior to traditional fermentation in terms of vanillin content and volatile components,and the research results provide certain data support for the preliminary processing of vanilla beans with microbial assistance.
