Question: are there chemicals in vegetable oil?
Answer: Vegetable oils, as used in foods, are comprised of complex mixtures of triacylglycerols (TAGs; usually > 95%) with some minor amounts of diacylglycerols (usually < 5%). Other minor components are tocopherols/tocotrienols (up to 900 mg kg−1) and phytosterol esters/phytosterols (up to 1%).
