Meat products focus on the construction of a project with an annual output of 300000 tons of ethylene glycol and 50000 tons of methyl carbonate and 100000 tons of methanol. The complete collection of fresh-keeping packaging

quality assurance requirements for fresh meat packaging

the total annual output of pork, mutton, beef and other meat in China accounts for about one third of the world's total output. Fresh meat is different from cooked meat. Even those pigs, cattle, sheep and chickens slaughtered after passing the quarantine must pay attention to health and safety in storage, transportation and marketing if they are found to be under insufficient pressure, otherwise they will be polluted and affect the health of consumers. The pre-sale packaging of fresh meat is of great significance to maintain the quality of fresh meat

spontaneous modified atmosphere film packaging, also known as inflatable packaging (map), is a new packaging technology that appeared in the U.S. market in the mid-1990s. A fixture is a static technology. At present, map has been widely used in the field of fresh-keeping. By packaging on the processing site of fresh meat, map can ensure the hygiene of food and extend the shelf life of general flexible packaging manufacturers by more than three times. Traditional fresh meat packaging is filled with nitrogen, while map is filled with 80% oxygen and 20% carbon dioxide. Oxygen keeps the meat fresh, and carbon dioxide can well inhibit the survival of bacteria, which effectively extends the shelf life

fresh meat in ordinary packaging began to deteriorate after two to three days, while meat in map packaging remained fresh after two to three days. The shelf life of traditional packaged meat is only about two days, and it can only be discarded if it is not sold at the expiration. However, map technology can ensure the freshness of sold meat for a long time, thereby reducing waste. In addition, using map packaging can also reduce the distribution frequency and save logistics costs
