No, it is not food safe. I e-mailed the company about this and was told not to use it on food.
The propellants in it and the metals in the can, etc., are not food safe. When the air passes thru it, some amount of those materials mix with the air and are deposited on the food.
Yes, the trace is minute, but given that there are other options............
The same propellants are used in food safe products, but fact is, the source for those materials is food safe. They cost more because it costs more to make sure that things are purified and then certified food safe.
The Preval is a useful tool for displays and for items that absolutley will not be eaten.
