Freezing time has great influence on the quality of foods and energy consumption in the process of quick-freezing.The prediction of freezing time is beneficial to improve the frozen food quality and optimize the quick-freezing facilities.The methods of predicting freezing time were analyzed by three ways: simple equation method,numerical method and artificial nerve network method.The definitions,characteristics,relative merits,research situation and range of application of the three methods were reviewed and compared.Finally,it was concluded that simple equation was simple and easy to use,but the accuracy was worse and it could not be universal.But numerical methods were currently used widely due to its wide application and low cost.And artificial nerve network method was just a way to investigate the new methods for the prediction of freezing time and served as a complement to numerical methods.Therefore,suitable methods should be chosen according to actual needs in freezing time predication.
