Preservation principle of compound atmosphere modified packaging machine

1. Modified Atmosphere Packing (MAP) is also called gas displacement packaging. The principle of compound modified atmosphere packaging machine is to use compound fresh-keeping gas (2-3 kinds of gas mixed according to the characteristics of food), to replace the air in the packaging box or bag, change the external environment of the food in the box (bag), to inhibit the growth and reproduction of bacteria (microorganisms), slow down the metabolism of fresh fruits and vegetables. And prolong the shelf life or shelf life of food.

2. Modified atmosphere fresh-keeping gas is generally composed of carbon dioxide (CO2), nitrogen (N2), oxygen (O2) and a small number of special gases. CO2 gas can inhibit the growth and reproduction of most spoilage bacteria and molds, and is the main inhibitory component in the protective gas; O2 can inhibit the growth and reproduction of most of the anaerobic spoilage bacteria, maintain the color of fresh meat, maintain the aerobic respiration of fresh fruits and vegetables, and maintain freshness; N2 is inert gas, and does not work with food, as a food. In order to fill the gas, a compound fresh-keeping gas is composed of CO2, O2 and special gases. Different foods and fruits and vegetables have different compositions and proportions of fresh-keeping gases.

 Key technology of modified atmosphere packaging machine

There are two key technical indicators for qualified packaging machine of modified atmosphere (CAM) fresh-keeping, which are high gas displacement rate and low gas mixing precision error rate. It is necessary to use these 2 key indicators to judge whether the quality of the compound atmosphere modified packaging equipment is qualified or not. Modified atmosphere fresh-keeping gas is generally composed of carbon dioxide (CO2), nitrogen (N2), oxygen (O2) and a small number of special gases.

Carbon dioxide is the main antimicrobial component in fresh-keeping gases, which can inhibit the growth and reproduction of most spoilage bacteria and molds and slow down the metabolism of fresh fruits and vegetables.

Oxygen can inhibit the growth of most anaerobic bacteria, maintain the color of fresh meat, maintain the aerobic respiration of fresh fruits and vegetables, and maintain freshness.

Nitrogen is a kind of inert gas, which does not work with food. As a filling gas, nitrogen is composed of carbon dioxide, oxygen and special gases. Different foods, fruits and vegetables need different fresh-keeping gases.
