Two mathematical models were used to predict the shelf life of tea soda crackers and compare error value and the optimal model was determined. Base on the theory of first-order kinetics model, the peroxide values of tea soda crackers stored at different temperatures (24,4, 44,4℃) were studied. Moreover, the correlation between the storage temperature and reaction rate of peroxide value was established using the Arrhenius equation and Q₁₀ equation and the shelf life of tea soda crackers stored at different temperatures (28,38,48℃) were compared with the real values. The results showed that the maximum prediction errors of the Arrhenius model and Q₁₀ model were 10.9% and 4.3%. Therefore, the Q₁₀ model could be used to establish the correlation between the shelf life and temperature. Compared with the Arrhenius model, the Q₁₀ model had the higher precision to predict the shelf life of tea soda crackers.
