Abstract:
As one of the most typical representatives of Chinese rice wine, Hong Qu glutinous rice wine is brewed from glutinous rice with the addition of two traditional fermentation starters-Hong Qu (hóng qǔ) and Yao Qu (yào qǔ). The traditional fermentation starters(Hong Qu and Yao Qu) are crucial to the flavor characteristics and flavor quality of Hong Qu glutinous rice wine. Therefore, in this study, the volatile flavor components of four kinds of commonly used traditional fermentation starters(Gutian Hong Qu, Wuyi Hong Qu, Longyan Yao Qu, Nanping Bai Qu) for Hong Qu glutinous rice wine brewing were extracted using headspace solid phase microextraction(HS-SPME) technique, followed by gas chromatography-mass spectrometry(GC-MS) combined with identification of volatile flavor components based on spectral database retrieval technology. Results showed that 50/30 m DVB/CAR/PDMS fiber is the most suitable for the extraction of volatile flavor components from traditional fermentation starters for Hong Qu glutinous rice wine brewing. This study identified 62 kinds of volatile flavor compounds from four different traditional fermentation starters with matching degree at least 80, including 17 alcohols, 9 aldehydes and ketones, 4 phenols, 8 esters, 11 acids, 5 kinds of pyrazines and other 8 compounds. Furthermore, characteristics of volatile flavor components of different traditional fermentation starters were found out through principal component analysis(PCA) and contribution analysis, and results showed that the difference of volatile flavor composition between Gutian Hong Qu and Wuyi Hong Qu is more significant than that between Longyan Yao Qu and Nanping Bai Qu. This study showed great value in scientifically understanding of the brewing mechanism and provide useful information for the selection of beneficial microbial strains to improve wine quality. © 2019, Editorial Office of Journal of CIFST.
