Trans fatty acid is an unsaturated fatty acid harmful to health, which exists in a small amount in natural fat. In addition to the hydrogenation of oils and fats is the main source of trans fatty acids, the content of trans fatty acids will also increase during the refining and deodorization process due to high temperature treatment. When cooking, you are used to heating oil to smoke and fry food repeatedly, and the trans fatty acids in these oils will also increase.
