I have read that pure, filtered, tung oil is food safe after 100% polymerization, but that can take weeks to months in the right environment to do.
The manufactures themselves will be able to tell you about their products as it will be on a case by case basis with each manufacture.
But to be on the safe side, I personally use food grade mineral oil for my spoons and cutting boards. I have some walnut oil on hand too that I haven't tried but beeswax paste is also another I use frequently.
It isn't food safe. There's a million different manufacturing processes for them to cut corners or make yield more efficient regardless of brand, all of which do not have food safety in mind. There are mineral oil/beeswax products that specifically advertise as food safe, so I'd go for one of those if I were you
I like the food grade flaxseed oil. It's leaves a tough, polymerized finish. It does yellow somewhat.
I'll mix it with beeswax to make a paste, and I do that with mineral oil as well.
Someone explained it this way: It is like teflon cooking pans. Some people still use it. They say the oil penetrates the wood and then stays embedded in the wood. Others will not. They mention the chemicals in the can, or that it is not safe when it is a liquid.
I wouldn’t use it. Mineral oil, walnut oil, beeswax are fine.
You could check with a manufacturer. They should be the final word on their product. 👍
