It could be. See tips on certain foods at: http://lancaster.unl.edu/food/ftfeb03.htm#vegetable Regarding vegetable oil, that site says: * 1 to 6 months opened; 6 to 12 months unopened Times vary according to type of oil, method of processing, etc. Some companies recommend up to 1 year opened and 2 years unopened for certain of their oils. For oils with a shorter storage time, some companies recommend refrigerating the oil after opening. See "Kitchen Cupboard Management 101" at the end of this article for suggestions on how to contact the company for more information. NOTE: If the container has sat unopened for the total storage time, it no longer may be fresh the entire "opened" storage time. * Storage Tip #1: Store in a tightly closed container in a cool, dark place. * Storage Tip #2: Some of the oils that may have a shorter storage life include walnut, sesame, hazelnut and almond oils. * Storage Tip #3: Oil that has been stored too long will go rancid and develop an undesirable taste and odor. If you haven't used an oil for a while, smell it before using it in a recipe. * Storage Tip #4: You can prolong the life of oils by storing them in the refrigerator. Some, such as olive oil, may become cloudy in the refrigerator but usually clear after sitting at room temperature to warm up.

Although cooking oils don't absolutely have to be refrigerated, they will last much longer if they are. Some oils will turn cloudy in the fridge (such as olive oil), but bringing them to room temp. will return them to normal consistency. Overall, your oils will keep much longer without going rancid if you keep all of them in the fridge. Exceptions are oils that are very high in saturated fats, such as palm, coconut, etc.

Vegetable shortening does not need to be refrigerated unless there are other ingredients added. In the United States, the label should say if it needs to be.

Is canola oil considered vegetable oil?

"Cooking oil" is actually a broad term for purified fat derived from plants which is normally liquid at room temperature. "Vegetable oil," when used to label a cooking oil product may refer to a specific oil like rapeseed oil or to a blend of different oils. Not all vegetable oils are edible - some are useful only as fuel oils. Not all cooking oils are vegetable oils - for example there are several nut oils and oils from gourds and melons that can be used in cooking. The non-vegetable cooking oils are seldom used in baking, so for the purposes of baking, the terms cooking oil and vegetable oil are pretty much interchangeable. Any recipe that calls for one can use the other interchangeably with the caveat that some oils are lower fat than others and some of them are more tolerant to heat than others. Olive oil can be substituted for cooking oil, but it changes the flavor a little bit.

Does cooking with vegetable oil help the environment?

No, cooking with vegetable oil has no benefit to the environment.Using vegetable oil to run your diesel vehicle, on the other hand, does help the environment, because burning vegetable oil (unlike fossil fuel oil) does not add extra carbon dioxide to the atmosphere. (The carbon dioxide released was removed from the atmosphere recently, when the vegetable was grown, part of the carbon cycle.)
