PLC Industrial Vacuum Food Sealer MAP Tray Packaging Machine With Trays

The principle of modified atmosphere packaging:

Fruits and vegetables contain a lot of water, and they continue to breathe after picking, resulting in the consumption of nutrients and the quality of fruits and vegetables. At the same time, the high moisture content of fruits and vegetables is also likely to cause damage by microorganisms and insects, resulting in a reduction in the edible value of fruits and vegetables and huge economic losses. Therefore, it is of great significance to study the storage and preservation technology of fruits and vegetables, prolong the storage time and reduce the storage loss.

The modified atmosphere packaging of fruits and vegetables can minimize the respiration rate of fruits and vegetables, reduce aerobic consumption, control anaerobic breathing, maintain moisture and taste, and maximize the shelf life of fruits and vegetables. The technology has unparalleled advantages. Modified atmosphere storage and preservation is currently recognized as the best storage and preservation method for fruits and vegetables in the world.

Key factors of modified atmosphere packaging for fruits and vegetables

1. Temperature
Low temperature conditions can reduce the respiration, transpiration and oxidation rate of fruits and vegetables
When growing, below a certain critical temperature, the activity of microorganisms will completely stop.

2. Respiration
The respiration rate of fruits and vegetables will directly affect the shelf life of the fruits and vegetables. It is of great significance to determine the respiration rate of the fruits and vegetables to be packaged.
A method for accurately measuring the respiration rate of fruits and vegetables.

3. Gas
CO2 has a certain protective effect on various fruits and vegetables, can inhibit bacteria
And fungal growth, the higher the concentration, the slower the fruit ripening,
Aging, reduce the respiration rate, but at the same time, when the CO2 concentration is higher, it dissolves
Carbonic acid will be formed in the fruit, changing the pH and flavor of fruits and vegetables, will cause
Shrinking packaging affects appearance and may even cause fruit poisoning. Reducing the concentration of O2 in the package will reduce the respiration rate of fruits and vegetables, but too low O2 content will cause hypoxic damage (hypoxic environment metabolizes harmful substances by anaerobic exhalation, reducing the quality of fruits). A certain high oxygen environment can inhibit the growth of certain bacteria and fungi, reduce the rot of fruits and vegetables, reduce the respiration rate and ethylene synthesis of fruits and vegetables, slow tissue browning, and improve the quality of fruits and vegetables.

4. Packaging materials
The modified atmosphere of fruits and vegetables also requires that the packaging materials have air permeability that meets the breathing frequency of fruits and vegetables, so as to create a balanced breathing space for the preservation environment of fruits and vegetables, and achieve the best storage time for fruits and vegetables. Gas component, but the permeability of common packaging films currently on the market is generally low, especially for some fruits and vegetables with high breathing rate, they rarely meet the requirements of their modified atmosphere packaging, and micro-breathing film can greatly improve the permeability of the film , Breathing oxygen, releasing carbon dioxide and ethylene, micro-breathing modified atmosphere preservation technology has become the main direction of fresh packaging of fruits and vegetables.

Several kinds of protective gas for commonly used food modified atmosphere packaging and the recommended ratio:
