Research Progress on Preparation of Ice Slurry and Its Application in Aquatic Products

Ice slurry can effectively inhibit the growth of endogenous enzymes and microorganisms in aquatic products because of its good fluidity and high cold storage density. It is a hot spot for experts in aquatic products and related fields. This paper summarizes the preparation technology of fluid ice, including method of fluidized bed, vacuum, scraping, supercooling and direct contact. At present, method of scraping and supercooling are widely used in commercial application. In addition, the preparation technology, growth and inhibition conditions, hydrodynamics, thermodynamic characteristics and its application in aquatic products are also explained in this paper. The main problems existing in the application of this technology in aquatic products and improvement suggestions are put forward, which can provide reference for future aquatic product storage and transportation technology and commercial application of ice slurry.
