Hello, 

I want to ask if there is any regulation or requirements about deoxidizer bags in EU. or how it can be choose for products?

Tamari,

 

Are you talking about the Silica gel packets in food?  The FDA recognizes it as non-toxic and Generally Recognized as Safe.  So it can be added to food packaging and come into contact with food without being an issue at all.  As such, there are no real requirements that I have found for it, only that you buy it from a reputable company that doesn't mix in other chemicals.  The EU created legislation in 1998 banning Silica gel that contained cobalt chloride, marking it as a carcinogen.  Silica gel packets have been altered to leave this ingredient out (which was for coloring anyway).  As I mentioned, I would ensure that your silica gel packets do not contain that chemical, or really much of any other chemical if you can manage it, in order to stay compliant with EU regulation.

Brendan Triplett, 

 

 have following guidance  from client and they want to  those composition was for  deoxidizer bag. Ferrous Powder: 70%, Salt: 9%, Moisture: 4%, Activated Carbon:7%, Sodium chloride: 5%, other: 5%. But they don`t give size requirements and the most important question is if there is or  not any size limit of deoxidizer bag?  as I think size should determine effectiveness of deoxidizer.

Tamari,

 

This is my fault.  You are looking to remove oxygen not moisture.  Here is the article regarding legislation and safety measures in the EU for oxidizers.  Long story short is that all of the materials are considered safe and you can use the packets without a lot of red tape.

As for measurements, there are a lot of sites on the internet that can give you measurements.  This is the general formula for the cubic centimeters of oxygen absorption required:

 

Container volume – Food volume = Residual air volume

Residual air volume x 0.2095 (because air is 20.95% oxygen) = Oxygen absorber size requirement

 

You will be able to confirm the makeup of the bags by reviewing that with the manufacturers that you touch base with.

Hope this helps.

 

Cheers!
