Vegetable oils are oils that have been extracted from various seeds. The most common include rapeseed (canola oil), soybean, corn, sunflower, safflower, peanut, etc. Unlike coconut oil or olive oil that can be extracted by pressing, these new-fangled oils have to be extracted in very unnatural ways.
How long does vegetable oil last? There are quite a few kinds of vegetable oils, like soybean oil, sunflower oil or peanut oil. Their shelf life, however, is quite similar to one another. As long as your vegetable oil is unopened and stored properly, it should be fine for at least two years, probably for a lot longer. Once youâll open the bottle, the oil in it should be fine for at least a year. If youâll store vegetable oil the right way, youâll prevent it from going bad for a longer period of time, even much longer.
