Re: Valencia Oranges
Yes, even olive oil can go rancid. Most olive oils can go 3 to 4 years before the taste is affected. The nice part about olive oil is that the "racididy" only affects the flavor. It is not harmful to eat even if it is rancid. Some people prefer the flavor of a rancid olive oil.
The key for the freshest flavor is to control the oxidation of the oil. Just like iron rusts ( converts iron to iron oxide when exposed to oxygen), olive oil oxidizes. The extend the life of your oil do the following.
1. Keep your oil sealed. This prevents fresh oxygen from contacting your oil and keeps the rate of oxidation a minimum.
2. Keep your oil in a dark container or dark place. Light increases the rate of oxidation.
3. Keep your oil cool. Preferably less that 80 degrees F ( 27 degrees C) Heat also increases the rate of oxidation.
