What makes you say that? Are you talking about virgin oil? I've had RBD coconut oil go mouldy in summer if it's been contaminated by other stuff, and I had a forgotten tub go mouldy in the back of the fridge after years of neglect, but the bucket of RBD oil in the pantry seems to be fine after months as long as it is not contaminated. Coconut oil has such a mild flavour and aroma that I think mould would be noticed at a fairly low level.jyb said:But coconut oil is indeed pretty mouldy when it is packaged, the mould doesn't all survive over time *apparently*.
Even mould that has subsequently died off would leave behind unpleasant/toxic residue. Hopefully the refining processs clears this?
