Hello Everyone.

Greetings from Colombia, South America!

I have been trying to find out, how food grade DE is made. So far I know DE is mined, but haven't been able to find if it is mined food grade already or if it need a purification process of some form, and if so, what process is it?

If anyone here have any idea please comment.

Thank you very much in advance!

Juan

All DE is food grade when it is mined. The only reason you see some DE not labeled as food grade, is because manufacturers tend to put other stuff in with it that is not safe to eat.

Juan,

You are correct that DE is dug out of the ground. Food grade is just crushed rock from the ground. There are 2 other kinds of DE that are heated and then used for filtering stuff. Those 2 are not the food grade type.

Just like anything dug out of the ground, different mines have slight, different variations of content. Some veins are more "pure" DE. This DE should have a pure white color and it is super light in weight (perma-guard brand in the usa). Other DE's have a slightly darker color. The DE we sell is mined in a location that contains calcium bentonite and is darker.

Depending on what you are looking for, I welcome the micro-nutrients and the trace minerals as long as the DE is food grade. I think it is good to try all the different types of food grade DE.

Blessings.
