Commonly used domestic and foreign protective gases are CO2 (carbon dioxide), O2 (oxygen), N2 (nitrogen) three. Their respective functions are: CO2: is a bacteriostatic gaseous agent that inhibits the growth and reproduction of bacteria. Its characteristics: the best antibacterial effect in the bacteria began to propagate the curve of the lag price (inhibition of bacterial index of about 100 / 100g or less); at low temperatures easily soluble in water and fat; it is the majority of aerobic Bacteria effect, but ineffective for anaerobic bacteria and yeast. Usually the minimum concentration of bacteria is 30%. O2: its role in three ways: to inhibit the growth and reproduction of anaerobic bacteria; keep fresh pigs, cattle, mutton red color; keep fresh fruits and vegetables metabolism aerobic breathing. N2: inert gas, and food does not work, only as a mixed gas filling gas.
Widely used in fresh meat, cooked meat, poultry, fish and fruits and vegetables and other snack foods or bread, cakes and lunch and other cooked food packaging, due to better maintain the original taste of food, color, shape and nutrition, To achieve a longer shelf life, has been more and more food processing manufacturers and consumers of green ignorant. In Europe and the United States market in the use of fresh and fresh packaging of food development is very rapid, the annual growth rate of up to 25%, the current domestic market every year, fresh air-conditioning packaging students. The annual growth rate of 20%, to replace the traditional food vacuum packaging high temperature, high pressure sterilization, product quality can not keep the shortcomings.
