This seems to suggest that canned foods are heated inside of the can. But cans are usually lined with BPA or similar chemicals on the inside. Wouldn't those melt at such temperatures?



Wikipedia says BPA has a melting point of 158-159 C, though I don’t anything (not even the name) about whatever chemical will replace BPA now BPA is regarded as an endocrine disruptor.
