Knowledge frozen meat refrigerated cargo

Knowledge frozen goods refrigerated meat: Chilled inactivating enzymes can break down, slowing the oxidation, inhibit microbial growth and reproduction, so that the meat in a dormant state, production remains a few weeks or even a few months after the original mass consumption. Frozen storage is a scientific method of preservation of perishable meat, meat products due to the enzymatic decomposition, oxidation and microbial growth and reproduction and lose value. But less than the low temperature -23 ℃ -18 ℃ low temperature refrigeration can be doubled to extend period, usually meat below -18 ℃ is reached hibernation. Cold storage at -30 ℃ is longer than in frozen storage at -18 ℃ period more than doubled, pork most obvious. Many countries clearly defined, frozen food, manufactured goods and fish must be transported at a temperature of -18 ℃ or lower. A cargo ship customer requirements during transport maintain the temperature below -18 ℃. 1 frozen meat refrigerated and then watertight composite materials, packaging, poultry, meat generally based on customer requirements or habits of the importing country is divided. Avoid water loss caused by dehydration moisture loss, then into cartons. Cartons must be applied seal, binding, along with identification tags. Freezing process should avoid carton deformation, which affects both the appearance and the loss of effective stowage space cold box. 2 frozen poultry refrigerated more vulnerable to degradation. Therefore, poultry muscle tissue of poultry, meat richer than muscle tissue. Poultry should use airtight composite materials, packaging, and transportation at temperature below -18 ℃, to avoid fat oxidation, dehydration moisture loss and spoilage bacteria breeding 3 frozen fish and seafood refrigerated eight amino acids the human body must also . Fish and fish products compared with poultry meat, fish and fishery products containing mainly water, proteins, fats, minerals, enzymes and vitamins. Wherein the protein content is high. Soft muscle tissue, unsaturated fatty enzyme content, and enzyme content is high. And before there is a stiff surface mucus secretion process, after the death of fish and fishery products not only appear stiff, mature, autolysis and rancidity four stages. This mucus is a good medium for spoilage. The four stages of short duration, in particular a very short maturity softening, because a variety of enzymes and microorganisms are still at a very low temperature activity. Autolysis stage, protein and amino acid decomposition spoilage microorganisms multiply, so that the quality deteriorates.
