Yes, olive oil goes bad. Unlike other highly refined oils, olive oil is natural and direct from the olive fruit. Being natural it has many health benefits & nutrients that can break down. Most don’t even think about cooking oils as something that can go bad, but the truth is that olive oil is quite sensitive to things like light, air and heat. Stored improperly it can turn “rancid” very quickly – in some cases in a matter of weeks. Although rancid oil can make you ill, you generally will notice the pungent and acidic nature of expired oil. However a good filtered oil stored out of the light and air at room temperature can last years! All our Parthena products are good for 1 year from the date of opening!
