How to freshen food by air-conditioned clingfilm packaging machine?

Fresh air packaging is also known as lock installed, this is a kind of can in the packaging can maintain food freshness and can prolong the shelf life of a kind of packing method, in this way out of food, however, retain the original, also because of the gas film packaging machine, pushed the local snacks with local characteristics to the table, And this air conditioning clingfilm packaging machine is how to lock fresh food? Let's have a look at it.

Application of modified atmosphere preservation technology

Gas cling film packaging machine can realize to the food fresh function locks, this is mainly because it USES the modified atmosphere technology, this kind of modified atmosphere technology is a new kind of food preservation technology, the working process of the main is to use mixed gas protective (usually in the form of CO2, N2 and O2) replacement of air inside the packaging, use a variety of different role in the protection of gas, Prevent the growth and reproduction of most microorganisms that cause food deterioration, and reduce the breathing speed of food (vegetable and vegetable and other plant foods), so as to make food fresh and prolong the fresh period.

Two, the effect of different gases on food

Protective gas filling a box in the environment changed, thus reduce various microbial breeding, and the different gas filling ratio is different for different food, it is in use process need based on features of packaging of food, and the commonly used mixed gases generally divided into carbon dioxide, nitrogen, oxygen, the three kinds of gas, Carbon dioxide prevents aerobic bacteria and most microorganisms from multiplying, oxygen mainly prevents anaerobic bacteria from multiplying, nitrogen has no effect on food, and is only used as a filling gas in the mixture.

Three, residual oxygen

Gas cling film packaging machine in the process of packaged food, need to see whether the residual oxygen box under reach a certain standard, generally is between zero point five percent and one percent, if you exceed this standard, even if the inflatable gas purity is higher, there is no guarantee that the shelf life of product, so need to make sure that before packing box of residual oxygen is in accordance with this standard.

To sum up, can see air cling film machine mainly depends on the modified atmosphere packaging technology for a variety of different gases are mixed, first take out the air in the box, and then after filling the mixed gases, the effect of this way to prolong the shelf life, through this kind of packing way out of the meat and the color of fresh vegetables will not change, It is precisely because of the emergence of this kind of packaging, so that this kind of food can also be packaged to achieve the effect of extending the shelf life!
