Shelf-Life Prediction of Chilled Chicken Based on Total Volatile Basic Nitrogen

Arrhenius equation was used to establish the shelf-life prediction of chilled chicken based on total volatile basic nitrogen (TVB-N) at different temperature (5, 10 and 15 ℃). The prediction model was verified internally and with actual samples. The results showed that the Ea of the model was 52.636 kJ/mol, and that the k₀ was 3.8×10⁷. 5, 10 and 15 ℃ were selected as the internally verification temperature, while the relative errors were 6.30%, 6.00% and 3.91%, respectively. The maximum relative error of actual sample verification was −10.5%. These showed that the model could accurately predict the remaining shelf life of chilled chicken under certain conditions. In a word, the shelf life of chilled chicken at different storage temperatures could be obtained through the perdition quickly, and it would provide theoretical basis for manufacturers and regulatory authorities to formulate shelf-life standards.
