该研究以中国五粮浓香型白酒核心产区—宜宾的浓香型白酒为主要研究对象,基于宜宾12家企业的48个样本,筛选出有代表性和差异性的14种酒样开展分析研究,构建了以宜宾产区为主的浓香型白酒感官评价术语体系。研究首先采用65名年轻消费者对14种以宜宾产区为主的五粮浓香型白酒进行盲评及描述性分析,结合Kruskal-Wallis检验及相关性分析等统计学方法,从消费者感知维度筛选出79个包括菠萝、苹果、高粱香、花蜜香、曲香、柔和等在内的描述词。研究同时通过12名白酒国家评委对18种浓香型白酒(成品酒及原酒各9种)的感官特性进行Napping分析,在解析宜宾产区浓香型白酒与其他产区代表性浓香型白酒感官特征差异的同时共收集了34个描述词。研究最后通过整合65名年轻消费者及12名白酒国家评委的描述词,确定了香气、口味、口感等95项感官描述词,并绘制了以宜宾产区为主的五粮浓香型白酒风味轮,研究成果为五粮浓香型白酒感官术语标准化及参比体系建立提供了依据,在一定程度上为产区企业优化产品定位、提升产区品牌竞争力提供了工具。
This study focused on five-grain Nongxiangxing Baijiu (strong-aroma Baijiu) from Yibin, the core production region of Chinese Nongxiangxing Baijiu.By collecting 48 samples from 12 companies in the Yibin production region, 14 representative and distinctive samples were selected for analysis and research, and a system of flavor lexicon for five-grain Nongxiangxing Baijiu, primarily from the Yibin production area, was established.Through blind tasting and descriptive analysis by 65 young consumers evaluating 14 Nongxiangxing Baijiu samples, combined with statistical methods including Kruskal-Wallis test and correlation analysis, 79 sensory descriptors were identified from consumer perception dimensions, such as pineapple, apple, sorghum, floral honey, and Qu flavor, and soft.Concurrently, 12 national Baijiu experts conducted Napping analysis (a projective mapping method) on 18 Nongxiangxing Baijiu samples (9 commercial Baijiu and 9 raw Baijiu), revealing sensory characteristics differences between different Baijiu samples while collecting 34 professional descriptors.By integrating descriptors from both consumer and expert panels, the study ultimately established 95 sensory terms covering aroma, taste, and mouthfeel attributes.A flavor wheel for Yibin five-grain Nongxiangxing Baijiu was developed accordingly.These findings provide a scientific basis for standardizing sensory terminology and establishing reference systems for five-grain Nongxiangxing Baijiu, while offering innovative tools for regional enterprises to optimize product positioning and enhance brand competitiveness.
