【Abstract】 Based on the 0-10 ℃ growth kinetics models of Shewanella putrefaciens,the Pseudosciaena crocea shelf-life prediction system by chill chain has been completed by application of Visual Basic language,and the prediction accuracy of this system has also been validated.This study adopted experimental data from naturally contaminated fish and established specific spoilage organisms’ growth kinetics models,which improved the accuracy of prediction.The reliability assessment between predicted value and observed value of Shewanella putrefaciens and remaining shelf life showed that the correlation coefficient R2 were both above 0.9,0.936 and 0.935 respectively.It indicated that the prediction system for Pseudosciaena crocea shelf-life by chill chain could quickly and reliably predict its’ freshness and the remaining shelf-life.Free-installation processing is adopted during the development of this system to provide convenience for customers.更多还原
