12. Olive Oil
Olive oil should be stored in a dark, cool area in a tightly-sealed container to preserve its fresh flavor and its antioxidant benefits. Colder temperatures may cause it to harden into a butter-like texture which could compromise its integrity if left sitting for too long on shelves – according to one report by Journal of Food Science study on olive oil storage practices, its antioxidant benefits can diminish over time when stored for six months or longer on shelves.
