Shelf-life analysis and prediction model for live clam (Ruditapes philippinarum) of Sealed Package.

The Ruditapes philippinarum adopt vacuum, oxygen and air seal packing treatment at 273 K, 278 K, 283 K and 288 K. It can be seen that oxygen sealed packaging is very good compared to other methods. Over time, its sensory evalution, survival, and glycogen are all decreased. Conversely, the total number of bacteria and pH are increased over time, so the pH and glycogen change are different with the increase in storage temperature. The kinetics model based on Arrhenius equation could describe the total number of bacteria, Sealed packing with high precision pH value and glycogen live clam (Ruditapes philippinarum) combine vacuum packaging besides air packaging, At the same time, the changes of the total bacteria count and pH value were well fitted with the reaction kinetics during live clam were sealed packaging with air packaging.
