Guangzhou seafood cold storage, cold storage installation works Guangzhou, Guangzhou cold storage installation company fresh fish freezer - micro-frozen fish preservation method: micro-frozen preservation method is to catch deposited at a temperature below freezing their cell juice (about a 3 ℃) A mild preservation methods frozen. When partial freezing, there will be a layer of frozen food surface layer, it is also known as the "supercooling" or "partially frozen." The freezing point of fish varies depending on the type, as follows:? 0.7 a freshwater a 0.2 ℃, brackish water fish, a 0.75 ℃, migratory marine fish a 1.5 ℃, benthic marine fish a 2 ℃. Partial freezing methods from different countries adopted different species, the fish are mostly a partial freezing temperature 3? A 2 ℃. The basic principles of micro-frozen fresh low temperature can inhibit the growth of microorganisms, inhibition of enzyme activity. In the micro-frozen state, part of the water is frozen fish, some of the water freezing microorganisms also occur, due to the nature of the water has changed, change the physiological and biochemical processes of microbial cells, some of the bacteria can not adapt to begin to die, most addicted psychrophilum though not dead, but their life activity is inhibited, almost can not reproduce the same time, activity in the micro-frozen state is suppressed, so that we can make the fish to maintain freshness in a long time without the risk of spoilage. Compared to ice storage, micro-frozen preservation can extend the shelf 1.5? 2 times, namely 20? 27d. Advantages X partially frozen storage is less when thawing drip loss, body surface, good color, and less cooling energy. The disadvantage is that the technical requirements for the operation of Gao, in particular, strict control of temperature requirements, the slightest mistake will cause ice crystals to cell damage. Micro-frozen preservation method including ice salt mixture micro-frozen preservation method, cooling micro-frozen preservation method and low temperature brine micro-frozen preservation method.
