In order to investigate the freshness changes of Trachypenaeus curvirostris during storage at different temperatures and to monitor the shelf-life of logistics in real time， Trachypenaeus curvirostris were stored at -30， -18， 0 ℃ and 4 ℃ to determine their K value， volatile basic nitrogen （TVB-N） value and total number of colonies （TVC）， and the shelf-life prediction model was studied. The results showed that with the decrease of storage temperature， the decline rate of shrimp's freshness index also slowed down， the shelf-life was extended， and different temperature groups had a greater impact on the freshness index of shrimps. The kinetic model of storage temperature， storage time and K value， TVB-N value and total number of colonies constructed by using Arrhenius equation and combined with food TTT theory， shows that the fitting degree of each freshness index is good， and R2 > 0.9， the variable shelf-life prediction model of eagle claw shrimp has a higher accuracy rate for shelf-life prediction， and the absolute value of the relative error between the predicted value and the measured value does not exceed 5%. Therefore， the dynamic model based on the freshness index can be used to predict the shelf-life of the cold-chain logistics of Trachypenaeus curvirostris.
