Abstract
The rapid identification of the vintage of aged vinegar has always been a concern,and this study investigated the technolo-gy of identifying the vintage of Shanxi SHUITA aged vinegar.The sensory characteristics and taste of Shanxi SHUITA vinegar aged for 1 year,3 years,5 years,6 years,8 years,and 10 years were determined by sensory evaluation and electronic tongue technology respective-ly,and the relationship between the sensory characteristics and taste of Shanxi SHUITA aged vinegar and its aging year was analyzed,and a model was constructed to identify the aging year of SHUITA vinegar.Results showed that the variation of sensory scores of SHUITA aged vinegar with its aging year adhered to the Weber-Fechner law,indicating that the sensory characteristics of SHUITA aged vinegar could discern the age of the vinegar.After the electronic tongue detection data of SHUITA aged vinegar taste was divided and de-baselined,ei-genvalue extraction,and sensor screening,a Fisher model was constructed to discriminate the aging year of SHUITA aged vinegar,and the accuracy of this model reached 96％in the training set,and 93％in the validation set,demonstrating the feasibility of using the results of the electronic tongue detection of SHUITA aged vinegar taste detection for aging year of SHUITA aged vinegar discrimination.This research effectively discriminated Shanxi SHUITA vinegar of different aging years using sensory characteristics and electronic tongue technology.It offers advantages such as speed,precision,and ease of operation,which significantly benefit quality assessment,cultural preservation,market regulation,product innovation,and brand development.关键词
