模糊综合评判和百分制总分法在黄桃罐头感官品质评价中的比较

Comparison of the hundred- mark system method and fuzzy mathematics in sensory evaluation of canned peaches

百分制总分法是传统食品企业常用的感官质量评价方法,然而由于评定人员对质量品质与分项分值的对应难以把握,存在总分结果与整体质量判断偏差的问题。本研究参考黄桃罐头行业评分标准,通过百分制总分法与模糊数学评判方法对黄桃罐头质量评价结果比较分析,产品的总体可接受性和模糊综合得分之间的相关性(R2=0.9238),优于传统总分法的相关性(R2=0.8077)。结果表明模糊综合评判方法综合考虑了各分项品质在内的权重差异,更加贴近评价人员的整体质量判断感受,符合现代感官品评的心理学理论,可作为客观的反映产品的品质感官分析方法。

Hundred-mark system method is a conventional sensory quality evaluation method in food industry. However, it is difficult for evaluation personnel to correspond the quality with the subentry score, so there is always a deviation between the sum scores and the quality evaluation. In this study, the grading standards of canned peach industry were referenced, compared hundred-mark method and fuzzy mathematical evaluation method, correlation（ R2 = 0.9238）between overall acceptability and fuzzy products was better than correlation （R2 = 0.8077） of hundred-mark system method. The results showed that considering the differences of the weight of each component in the quality,fuzzy comprehensive evaluation method was more close to the evaluation of personnel＇ s overall quality judgments and feelings. The method was in line with modern psychological theory sensory evaluation.So it could be used as an objective method for sensory analysis to reflect the quality of the product.
