中文摘要:

      目的 通过风味分析确定花露烧酒新品中银杏果的最佳添加量。方法 采用固相微萃取-气相色谱-质谱法(solid phase microexteaction-gas chromatography-mass spectrometry, SPME-GC-MS)和感官评价技术测定比较了不同银杏果添加量的花露烧酒的挥发性风味成分。结果 共鉴定出52种挥发性风味成分, 各样品中香气成分的种类和含量有明显差异; 经与糯米混合发酵后, 银杏果中青草风味成分如壬醛、正己醛等显著下降或未检出; 采用主成分分析法得出银杏花露烧酒香气与苯乙醇、正己酸乙酯、乙酸异戊酯、庚酸乙酯、戊酸乙酯等风味成分有关。由感官分析可知银杏果添加量为25%的花露烧酒样品C整体感官品质最佳, 尤其是香气方面, 产生了令人愉悦的正己酸乙酯、乙酸异戊酯等风味成分。结论 添加25%银杏果的花露烧酒的风味较好, 为传统特色产品花露烧酒的创新提供了新思路, 对银杏花露烧酒的风味控制提供了理论依据。

英文摘要:

      Objective To determine the optimal addition of ginkgo fruit in new product of Hualushao rice wine through flavor analysis. Methods Solid phase microexection-gas chromatography-mass spectrometry (HS-SPME-GC-MS) and sensory evaluation techniques were used to detect and compare the volatile flavor components of Hualushao rice wine with different additions of ginkgo fruit. Results A total of 52 kinds of volatile flavor compounds were identified, and the types and contents of aroma components in each sample varied significantly. The grassy flavor components such as nonanaldehyde, n-hexanal, etc. in ginkgo fruit were significantly reduced or not detected after mixing and fermentation with glutinous rice. The principal component analysis method was used to show that the aroma of ginkgo Hualushao rice wine was associated with phenylethanol, ethyl hexanoate, isoamyl acetate ethyl heptanoate, ethyl valerate and other flavor components. According to sensory analysis, sample C with a 25% addition of ginkgo fruit had the best overall sensory quality, especially in terms of aroma, producing pleasant flavor components such as ethyl hexanoate and isoamyl acetate. Conclusion The research results show that the addition of 25% ginkgo fruit in Hualushao rice wine has a better flavor. It provides new ideas for the innovation of traditional specialty products such as Hualushao rice wine and provides a theoretical support for the flavor control of ginkgo Hualushao rice wine in the future.
