The effects of the headspace-generation time and pork sample mass on the response of the e-nose were studied using multivariate analysis of variance and oneway analysis of variance, respectively. The results showed that the pork sample mass had the most significant effect on the e-nose sensor response, followed by the headspacegeneration time. The optimum parameters were 10 g of sample mass with 5 min of headspace-generation time in a 500 mL vial. After either principal component analysis or linear discriminant analysis, the results showed that the e-nose with the optimum parameters can accurately classify the pork samples stored for 06 d. A method using a back propagation neural network was also performed, and 91.43% of the prediction set (with 92.86% of the training set) was classified correctly using this model. 電子鼻-Z傳感器生產(chǎn)商產(chǎn)品
