Abstract: In order to investigate the deterioration of the quality of low-temperature fried crisp dates during storage, four packaging methods, including PET vacuum packaging, PET vacuum+deoxidiser packaging, aluminium foil vacuum packaging and aluminium foil vacuum+deoxidiser packaging, were used to analyse the changes of acid value and peroxide value at different storage temperatures (25, 35 and 45 ℃) and to establish a prediction model for the shelf life of low-temperature fried crisp dates by combining the Arrhenius formula. The results showed that the acid value and peroxide value of fried crispy dates in the four packaging methods showed an increasing trend at different storage temperatures, with a low rate of change at 25 ℃. In terms of packaging effect, the lowest oxidation rate was observed in the aluminium foil vacuum+deoxidiser packaging method (K value = 0.0131 for acid value kinetic model and K value=0.0147 for peroxide value kinetic model), and the R² of the predicted shelf-life model was >0.90, with a good fit and the model error of the predicted shelf-life value was less than 10%. By comparing the quality changes of vacuum and low-temperature fried crispy dates in different packaging methods, the best result was obtained with the aluminium foil vacuum+deoxidiser packaging, which increased the acid value by 0.322 mg/g and peroxide value by 0.026 g/100 g for 60 days at room temperature, and the predicted shelf life reached 180 days.
