| 摘要: |
| [目的]建立啤酒口感协调性模糊综合评价法,使啤酒口感协调性感观评定结果趋于准确和客观,为啤酒质量稳定与提高提供可靠的评价保障.[方法]采用模糊数学综合评价法,通过隶属度描述10种市售啤酒样品的口感协调性特征,首先依次建立模糊综合评价指标体系、确定评价对象协调性指标论域和评语等级论域;再进行啤酒协调性单指标评价,确定评价指标模糊权向量a,建立模糊综合评价模型;最后对啤酒口感协调性模糊综合评价结果进行分析.通过感官对啤酒样品整体口感协调性进行品评,利用SPSS13.0数据软件对品评结果进行分析,最终确定啤酒样品口感协调性优劣等级,将此结果与模糊综合评价结果进行比较,以说明模糊综合评价法的有效性.[结果]感官品评法和模糊综合评价法得到的啤酒口感协调性结果基本一致,感官品评法不能将样品6与10,5与8区别开来,而模糊评价法则能很好地区分10种样品的口感协调性优劣.啤酒样品1和2的口感协调性最好,5和8的口感协调性最差.[结论]模糊综合评价法可用于啤酒口感协调性评价,与传统的口感品评法相比,模糊综合评价法更加客观准确,区分度更加明显. |

| Abstract: |
| 【Objective】 The study is aimed to establish a method of fuzzy comprehensive evaluation in beer harmony characteristic tasting,and to make the result of sensory evaluation more accurate and objective,furthermore,to improve the beer quality.【Method】 The method of fuzzy mathematics comprehensive evaluation was applied in the study,and the mouth-feel harmony characteristics of 10 kinds of beer were described by the membership grade:the system of beer taste compatibility comprehensive assessment indexes,region of indexes and grade of comments were identified first;then the evaluation of single index on beer harmony was carried out,and the fuzzy power weight vector‘a’was confirmed,and the model of fuzzy comprehensive evaluation was established;lastly，to make an analysis on the result of beer harmony characteristic tasting.Moreover,the whole harmony characteristic of beer sample was evaluated,and its result was processed by the date processing software SPSS13.0,and aftera while,the comparison of fuzzy comprehensive evaluation result and traditional sensory evaluation result carried out to show the validity of the former.【Result】 The two kinds of harmony characteristic results were basically consistent,which came from different methods.The sensory evaluation can not distinguish sample 6 and 10,5 and 8,while the fuzzy comprehensive evaluation can do all the 10 samples.The beer sample 1 and sample 2 were samples with the best harmony characteristic,in comparison,the beer sample 5 and sample 8 were the samples with the worst harmony characteristic.【Conclusion】 Fuzzy comprehensive evaluation can be used for beer harmony characteristic tasting.Compared with the traditional sensory evaluation,it is more objective and exact,and has more significant distinguish degree. |
