what does rancid oil smell like?
A pungent, acrid odor assaults the senses, a sharp, biting smell that stings the nostrils and leaves a lingering, unpleasant aftertaste. The scent of rancid oil is unmistakable, a combination of sourness and bitterness, reminiscent of decaying flesh or spoiled dairy products. It is a smell that can permeate an entire room, clinging to clothes and furniture long after the source has been removed. The smell is caused by the breakdown of the fatty acids in the oil, a process that is accelerated by exposure to heat, light, and oxygen. As the oil ages, the fatty acids become oxidized, producing a variety of volatile compounds that are responsible for the characteristic odor.

For these reasons, it is important to discard any oil that has gone rancid.
