Abstract:: Temperature is the major factor that influences the quality of fruits.Exploring the relationship between temperature and fruit quality is of great value to the improvement of circulation enterprises′ logistics quality.This study analyzed apple′s quality indexes with the change of temperature firstly,including firmness，color，TSS and titratable acid.It was found that the firmness and color index were more linearly correlated with temperature changes and they were more suitable to evaluate the quality of apple in the circulation.Then this study analyzed these two indexes combined with dynamics,according to the zero-level kinetic equation and the Arrhenius equation,we constructed the quality tracing model.The relative error rate of the model was 8%-15% and the prediction accuracy of b* in color index was higher.
