Alright I found the regulations. And there is NOTHING about the use of Medical grade CO2 in food products.

The gas supply store that I go to offers various grades of lab, medical, food & welders grades. There is a difference between food grade & welders grades.

Welcome to APC! When I was using pressurized CO2 I used fire extinguisher grade, if there is such a thing, from a fire extinguisher service place of business. I know some people use Welders grade, from welding equipment stores. And, some use restaurant grade from places that service bars and restaurants. I suspect it all comes from the same delivery tank truck. CO2 is a liquid, when sold, and that is a liquid that I doubt is a solvent for much of anything. So, when we use the gas from that liquid supply I think we can count on it being nearly 100% CO2.
