Xiaobian Mingwei analyzes why cooked food is packaged with modified atmosphere packaging machine for you
Cooked food products, such as braised chicken wings, duck wings, duck necks, fish, etc., because they are often ready-to-eat, they are not cooked before eating, so the requirements for food preservation are particularly important. At present, the best effect is the modified atmosphere packaging. , The commonly used packaging method in the market is to use vacuum packaging to solve the problem of freshness. Most businesses or enterprises hope that the shelf life of food can be effectively extended after vacuum packaging, which is convenient for sales and long-distance transportation, but because the length of the shelf life is greatly related to the sterilization process Therefore, sometimes food additives need to be added to the vacuum packaging machine to achieve a good preservation effect. Vacuum packaging will also destroy food fiber cells, and the gas fresh-keeping packaging process for cooked food is further in terms of quality. The following is a brief introduction to this new packaging method - modified atmosphere packaging
Modified atmosphere packaging is internationally known as MAP packaging (ie Modified Atmosphere Packing). The principle of the modified atmosphere packaging machine is to use mixed fresh-keeping gas (oxygen, nitrogen, carbon dioxide three gases are mixed according to the characteristics of the food) to replace the air in the packaging box or packaging bag. , Change the external environment of the food in the tray to inhibit the growth and reproduction of bacteria (microorganisms), thereby prolonging the fresh-keeping period or shelf life of the food. Different foods have different fresh-keeping gas components and proportions. The commonly used fresh-keeping gases for cooked food are oxygen and carbon dioxide. , The general mixing ratio is 30% CO2 and 70% N2. The ratio of the mixed gas must be accurate, otherwise it will affect the preservation cycle of the food. CO2 is a gas that inhibits the growth of bacteria, but it can only inhibit aerobic bacteria. However, it is ineffective for anaerobic and yeast, and the concentration must be accurate at 30%. Oxygen is only a filling gas and does not react with any food. Modified atmosphere packaging is batched in the process of storage, transportation and sales, and the temperature is always controlled. In the range of 0~4℃, the fresh-keeping period of the product can reach more than 7 days. Compared with the traditional processing technology, the whole process of modified atmosphere packaging has the characteristics of reasonable process, convenient operation and low energy consumption. It has outstanding characteristics such as color, fragrance, delicious taste, good shape, original taste, high hygiene and safety, and long shelf life. With the acceleration of the pace of life, the consumption of non-staple food will also increase in the future. Modified atmosphere packaging machines will also fully keep up with production needs. In the future, food safety will no longer be closely related to production and hygiene. There will also be strict requirements on modified atmosphere packaging machines. Modified atmosphere packaging machines are not only a basic demand for fresh food, but also a measure of living standards. standard.
The cooked food modified atmosphere fresh-keeping packaging machine is not only a fresh-keeping technology for food safety, but also an inevitable requirement for the development of the global food market. The meat industry has gradually entered the sequence of industrialization from agriculture, and has begun to enter the market in the true sense. Since the invention of the modified atmosphere packaging machine for food preservation, it has directly subverted the traditional meat sales model, and truly realized human beings for thousands of years. The food dream of keeping meat fresh, cooked food modified atmosphere packaging machines are widely used in the current food industry. Packaging materials with gas barrier properties are used in the packaging of food, which can well prevent food from being stored. The change in quality can keep the food safe for a certain period of time. The modified atmosphere packaging machine for cooked food has made great contributions to the society. The food industry has always been a very tight market in my country. Many people choose to eat packaged food, so there must be strict requirements on food packaging to ensure the safety of food shelf life. Because of food safety issues, China attaches great importance to the quality of modified atmosphere packaging machines. With the acceleration of urbanization and the continuous improvement of people's living standards, the fresh meat market will be further expanded. Consumers no longer just have choices in purchasing products, but choose consumption concepts and consumption patterns. Consumers pay more and more attention to the fresh texture, pure taste, green packaging and attractive appearance of meat products. Therefore, modified atmosphere packaging The installed machine has the effect of food packaging technology and preservation to meet the needs of customers. With the development of society and the increasing consumer demand for high-quality food, the use of modified atmosphere packaging machines to package products will become a new market trend.
