The development history of modified atmosphere preservation technology

With the improvement of people's living standards, there is a strong attraction to fresh food. The use of modified gas to pack perishable food has evolved into a market trend, so the requirements for food preservation technology are getting higher and higher, so Xiaobian Xiaobian will take you to a simple understanding of the development history of modified atmosphere preservation technology.

As early as the early 12th century, when fresh beef was shipped from New Zealand to England, it was transported or stored by increasing CO2 and reducing O2 in carriages or warehouses.

In 1970, the Danish Irma retail chain chain centrally produced modified atmosphere packaging for fresh meat in the Copenhagen distribution center and successfully supplied the whole of Denmark.

In 1976, in cooperation with the leading Danish manufacturer of meat products, MULTIVAC and the German WITT-GASETECHNIK established in 1945 obtained the first packaged fresh meat with mixed gas.

In 1980, UK vacuum packaging and modified atmosphere packaging accounted for about half of the European packaged food market. About 38% of the fresh red meat is packaged in modified atmosphere, and by 1982 the total sales increased by 300%.

Since the 21st century, about 80% of beef sales in the United States and Canada have been supplied to retailers, hotels, restaurants and government canteens by meat packaging manufacturers in the form of cut meat vacuum shrink packaging and modified atmosphere packaging; the current food retail chains in the United Kingdom are all Modified atmosphere packaging is sold; in France, baguettes, which account for a large portion of the fresh food market, have been particularly successful.

In addition to packaging cold fresh meat, German modified atmosphere packaging has also begun to popularize food such as instant noodles, pizza and fresh-cut vegetables. About 10% of cured meat and 72% of pies in Italy use modified atmosphere packaging.

In the late 1990s, my country began to research and develop fresh-keeping food packaging equipment and processes. For example, Shanghai meat processing enterprises introduced foreign modified atmosphere packaging equipment to develop the fresh pork modified atmosphere packaging market, which laid the foundation for the application of my country's food modified atmosphere packaging market.

Since the 21st century, the research and market application of modified atmosphere packaging for food has entered a period of development. Many colleges and universities, research units and forward-looking enterprises have done a lot of practice and research on modified atmosphere packaging technology.

Zhejiang Mingwei Packaging Machinery Co., Ltd. was established in 2014. It is a professional manufacturer of fresh-keeping equipment. The company is headquartered in Wenzhou, Zhejiang. Mingwei company has been engaged in the research and development, production and sales of food bag automatic packaging machines, modified atmosphere packaging machines, plastic wrap packaging machines, and food packaging machines for many years. The structure and related configuration of the machine are the same as those of foreign machines, and the fully enclosed vacuum displacement technology is also used for modified atmosphere packaging.
