Why do foods that use deoxidizers still deteriorate during the shelf life? The possible reasons are as follows:

1. The selected food deoxidizer does not match the model, and the quality of the food deoxidizer is unstable.

2. The material of the food bag does not meet the requirements, such as KOP/CPP, NY/PE, KNY/PE, KPET/PE, PET/AL/PE, etc. Do not use OPP/CPP, PP or PE film bags. The oxygen permeability should not be too high, and a composite packaging material with an oxygen permeability below 20ml/㎡·24h·25°C should be selected.

3. There may be air leakage in food packaging bags.

Fourth, the food deoxidizer is exposed to the air for too long, and it has expired before use.
