Summary To understand the quality changes in S ongpu mirror carp ( C yprinus carpio ) fillets during chilled storage, sensory score, total aerobic counts ( TAC ), total volatile basic nitrogen ( TVB ‐ N ) and electrical conductivity ( EC ) of the fillets stored at 270, 273, 276, 282 and 288 K were investigated. Furthermore, both A rrhenius model and log‐logistic model were established to predict the quality changes. The high regression coefficients ( R 2 > 0.90) represented the acceptability of both A rrhenius model and log‐logistic model. Relative errors between predicted values and observed values were all within ±5% for models based on EC , within ± 25% for models based on TAC and TVB ‐ N (except the TVB ‐ N value on 9th and 15th day). The relative errors of sensory score were all within ±35% in the first 9 days. It is concluded that both A rrhenius model and log‐logistic model based on EC , TAC or TVB ‐ N can be applied in modelling quality changes in S ongpu mirror carp fillets during storage within 270–288 K.
