E-Mail 'Letter: Advice on Oxygen and Moisture Absorbing Packets' To A Friend

8 Comments

1. This kind of information is why I visit this site every day. Thank you!

   1. My wife just asked me this the other day. I had no answer, but I do now! Great info jim!

2. Another little gem from Mr. Rawles.
   Great info!

3. Someone also pointed out those hand and foot warmer packs (they heat up when exposed to air) are basically the same chemistry as the oxygen absorbers and will have the same effect. I don’t think there would be a “food grade” problem if handled right, and I think they are cheaper especially for large containers.

4. I have been buying my O2 absorbers from https://www.sorbentsystems.com since prior to Y2K. (No commercial connection; I’m just a customer.)

   I figure it is better to over do it, so I use a 200 ml for a #10 can or a gallon glass jar and a 1500 ml absorber for a 5-gallon pail. If I’m doing something with lots of voids, like macaroni, then I double up.

   I have never used their moisture absorbing packets, but they sell those, too. I have purchased their heavy duty Mylar bags and they are nice and thick.

5. Empty new tea bags sealed with sticky tape make nice bags for Silica gel.

6. I made some years ago using the same silca kitty litter wrapped in coffee filters. I have also revitalized silca thats been exposed to moisture by putting it on a cookie sheet on very very low heat in the oven for an hour. Pretty sure i read that here on the blog.

   1. Sorry noticed it was already mentioned thru some blip that paragraph wasnt here when i first looked. Carry on!
