Abstract:

The most familiar specific spoilage organisms (SSOs) of fresh-water aquatic products are Pseudomonas spp. and Shewanella putrefaciens during oxygenic cold storage. It has been reported both at home and abroad that Photobacterium phosphoreum, Lactobacillus and Enterobacteriaceae are the SSOs of aquatic products stored in a vacuum environment or in an atmosphere modified package. The SSO composition of aquatic products processed under mild conditions was complicated and generally consisted of Lactobacillus, Photobacterium phosphoreum, Enterobacteriaceae and so on. Modeling for predicting the spoilage course and residual shelf-life of an aquatic product is one of the applications of the SSO concept, and another is the targeting inhibition for the prolongation of shelf-life.

Key words: aquatic product, specific spoilage organism (SSO) , storage, shelf-life
