Meat consumption is a measure of a country's level of people's living standards, a mark. According to data from China Meat Association, 2005, China's meat output reached 77.43 million tons. Of which: pork 50.1 million tons, 7.11 million tons of beef, mutton, 4.35 million tons, 14.64 million tons of poultry. Followed the development of the meat processing industry, both as an old industry, but also new industries, in playing an important role in people's livelihood.
Meat processing, including raw and cooked meat separate Meat Production of two parts, there are thousands of products. Health hot fresh meat products, frozen meat and chilled meat. Freshly slaughtered meat is eaten hot and good taste, put a long time perishable; frozen meat are often a result of frozen ice crystals pierce the membrane when thawing drip loss, and taste good; Chilled carcass temperature decline requests to -4 ~ 4 . After segmentation, packaging, from production to Sell Always controlled at this temperature, the microbial growth and enzyme activity was inhibited to maintain and improve the quality of meat and flavor. Currently, the market still IOUs based meat hygiene, cut meat, small package of meat for less than 10%. Even in Beijing, big cities like Shanghai, the retail market, not to market a small amount of chilled meat packaging to 20%.
1. Meat production Soft plastic packaging
Food packaging food prime objective is to ensure the safety and health, different kinds of packaging material to meet a variety of different meat products, packing and processing and storage transport requirements.
(1) package frozen cut meat Frozen meat by long-term storage is needed and exported the meat after the division of plastic, packaged packing (tray), low temperature (-25 ) to freeze. Cold storage can inhibit the activities of microbial life can be a long time to keep the quality of meat. Shelf life can reach more than 4 months. Can be used PET (polyester film) / PE (polyethylene) / AL (aluminum foil), etc. can be locked Composite Packaging Materials . But most businesses due to economic reasons, often using single polyethylene film.
(2) cooling the meat packing division
Exposed or only simple packaging of fresh meat, bacteria grow very fast. Room temperature, the shelf life of only half a day meat, frozen and only 2 days to 3 days. Cooling cut meat is processed by the division after 20 hours the meat will cool the body temperature to about 4 for packaging, strict control of the propagation of microorganisms. Packaged refrigerated vehicle to the set from the frozen food supermarket display container sales. Packaging generally use non-toxic, cold, good flexibility, transparent Plastic Film, so consumers see the true nature of raw meat.
Inflatable packaging used primarily for nitrogen and carbon dioxide gas. Can keep the meat oxymyoglobin color red, PA / EVOH / PE hot forming, good stiffness, high barrier properties, suitable for modified atmosphere packaging, PA / EVOH / PE barrier, and suitable for vacuum packaging. The shelf life of modified atmosphere packaging of approximately 14 days. The shelf life of vacuum-packed pork about 30 large, beef 80 days.
(3) for fresh meat preservation of the vacuum (fitted) Shrink Packaging
Vacuum (fitted) shrink bags have a good anti-wet, as opposed to non-contracted products, can improve the appearance of packaged products, to strengthen the protection of products, reduce blood leaking and extend product shelf life. American Vacuum Sealed Air's shrink bags in hot water at 854 up to 30% shrinkage to 50%, can even shrink, and with high oxygen barrier capability, and will further enhance the contraction.
(4) Western-style packaging of low-temperature meat products
Western cold products are often after the biopsy in a sterile room with vacuum packaging, packaging bags of food to the outside world. I am China Chemicals Products writer, reports some information about plasma tv lifts , adult cd universe.
