Modified atmosphere fruit and vegetable vacuum packing machine

Modified Atmosphere fresh packaging equipment 

Modified Atmosphere packaging is the world's most advanced food preservation packaging technology, which uses CO2, O2, N2 and other protective gas mixture to convert the air inside the package, the use of various gases play a different role in inhibiting the deterioration caused by the large food Most of the growth and reproduction of microorganisms, and make fresh fruit vegetables and other plant-based food to reduce respiratory rate, so that food preservation and extend the shelf life.

The shape of the finished product is boxed or bagged, and it is suitable for the logistics and sale of large packages of foodstuffs in the retail, wholesale and retail of supermarkets.
Food atmosphere preservation packaging several protective gas
Commonly used protective gas at home and abroad are CO2 (carbon dioxide), O2 (oxygen), N2 (nitrogen) three. Their respective functions are:
CO2: is a bacteriostatic gas that inhibits bacterial growth and reproduction. Its features:

(1) The best antibacterial activity is in the lag phase (the bacterial index of inhibition is about 100 / 100g) when the bacteria begin to reproduce.
(2) easily soluble in water and fat at low temperature;
(3) It has antibacterial effect on most aerobic bacteria, but is not effective on anaerobic bacteria and yeast.
(4) The minimum concentration of bacteria that is normally inhibited is 30%.

O2: Its role has three aspects:
(1) inhibit the growth and reproduction of anaerobic bacteria;
(2) keep the red color of fresh pig, beef and mutton;
(3) to maintain fresh fruit and vegetable metabolism aerobic respiration.
N2: inert gas, and food does not work, only as a mixed gas filling gas.

Application

It is widely used in the packing of cooked food such as cooked meat, poultry, fish, fruits and vegetables, cooked food such as bread, pastry and box lunch, etc. Since the original taste, color, shape and nutrition of the food are well maintained A longer shelf life, more and more food processing companies and consumers are ignorant. In Europe and the United States market with the atmosphere of fresh food packaging developed rapidly, the annual growth rate of up to 25%, the current annual domestic market fresh air conditioning packaging Health cooked products as much as 5 billion boxes. Annual growth rate of 20%, to replace the traditional high temperature vacuum packaging food.
