There is no precise definition of refined vegetable oil, nor is there a corresponding industry standard. The so-called refined vegetable oil is a general term for processed vegetable oil.
Everyone's favorite treats such as butter cakes, cookies, shortbread, fried dry pasta, fried bagels, potato chips, chocolate, salad dressings, burgers, French fries, fried chicken nuggets, popcorn, etc., all contain refined vegetable oils.
Some manufacturers clearly label the use of refined vegetable oils on their packaging, while many do not label the ingredients at all. Some refined vegetable oils contain trans fatty acids and some do not, depending on the refining process. Trans fatty acids are known to be very unfavorable to the human body, and consumers should be concerned about the total trans fatty acid content of grain products.
