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

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.
