Deoxidizers can be roughly classified into iron series materials and non-iron series materials according to their raw materials. In recent years, in such applications of deoxidizers, considering the prevention of foreign matter from mixing into the product, the finished packaging products need to be removed by metal detector. Therefore, in order to avoid interference, most of them do not use the deoxidizer of the early iron material system, but instead use the food packaging deoxidizer of non-iron material.

 

And the classification is more detailed: (1) General deoxidizer: suitable for high oil and high moisture food, such as moon cakes, fried goods, traditional Chinese medicine, pet food. (2) Water and oil resistant deoxidizer: butter cake, twist, honey cake, etc. (3) Water-dependent deoxidizer: This kind of deoxidizer in the air oxygen speed is very slow, but contact with food, after perceiving the water content of food will quickly absorb oxygen, its subcontract time is quite long, can reach 12 hours. (4) Continuous deoxidizer: This kind of continuous packaged deoxidizer is rolled. With the automatic feeding machine of deoxidizer, it can cut and put deoxidizer at 80-200 speeds per minute. (5) Organic deoxidizer: This kind of product can be sealed into food by metal detector, and metal detection can be carried out in the final process without affecting the detection effect. (6) Deoxidizer with oxygen indicator: Indicator and deoxidizer are integrated to intuitively understand the residual oxygen content in food bags after the deoxidizer is sealed into food packaging bags. When the indicator is red, it indicates that the food bag is anaerobic, and when the indicator is blue, it indicates that there is oxygen in the food bag. (7) Silica gel desiccant: safe and non-toxic, containing blue particles, transparent packaging, can be judged by color whether moisture has been absorbed, can be reused. (8) Lime desiccant: Quick absorption of water, with a strong water absorption capacity.
