In order to scientifically monitor sensory quality changes of chilled pork during cold chain logistics, the sensory characteristics of pork samples from distribution center, short distance supermarket and long distance supermarket during the progress of cold chain logistics were investigated, including odor, color, springiness, cooking odor and overall acceptability of pork samples. The distribution and the probability of different sensory indicators scores were studied by normality test. The key evaluation indicators was obtained by using sensitivity analysis and regression analysis, then according to its data distribution characteristics and its diagnostic value to overall acceptability, the control charts were designed to visualize the fluctuation of sensory characteristics distinctly. The results showed that: overall, there were significant difference in the sensory quality of pork samples from distribution centers, short distance supermarket and long distance supermarket; color is the sensitive indicator to evaluate overall acceptability, and its mean standard deviation control chart were designed; there were more sensory quality fluctuations in distribution center, and its process capability index was lower, thus it was need to improve quality management. The product quality fluctuation and its qualified ratio were distinctly visualized by mean standard deviation control chart, and it would provide scientific management method for monitoring pork appearance changes in cold chain logistics.
