My guess is that it does denature the oil.

You can get enamel-lined cans. Still, they use lead compunds in the solder
(if the can is round with a seam). The big problem with any soft plastic is
the pthalates used to make the plastic soft, which allow chemicals like
vinyl (which contains lead) to leach out of the plastic. PVC is one of the
most toxic plastics. It's recycle code is 3. You should never let PVC come
into contact with food, especially hot food. At my local sushi bar, they
pack the 8-pc sushi in PVC containers! They justfy this by saying the sushi
is cold, so it's safe. By the way, PVC cannot be recycled and doesn't
biodegrade. It leaches so much lead into the landfills that some districts
won't put it in their landfills. Bad stuff.
