Trans fat can be an unintentional byproduct of the industrial processing of oils. Unlike naturally derived trans fats, the trans fats that result from hydrogenation consist of many isomers. In food production, liquid cis-unsaturated fats such as vegetable oils are hydrogenated to produce more saturated fats, which have desirable properties:
A 2006 study supported by the National Institutes of Health and the USDA Agricultural Research Service concluded that palm oil is not a safe substitute for partially hydrogenated fats (trans fats) in the food industry, because palm oil results in adverse changes in the blood concentrations of LDL and apolipoprotein B just as trans fat does. [92 ...
Improved hydrogenation processes can produce partially-hydrogenated oil with much lower amounts of trans fat. [ 2 ] Oils rich in monounsaturated fatty acids (especially oleic acid ) obtained from plant breeding have higher stability compared to their polyunsaturated-rich ancestors, offering a similar improvement to shelf life.
Small amounts of trans fats can increase the risk for cardiovascular disease significantly,” says Dr. Lopez-Jimenez. “They usually come in the form of partially hydrogenated fats and may be ...
Thirty years later Michel Eugène Chevreul deduced that these fats were esters of fatty acids and glycerol. Wilhelm Normann, a German chemist, introduced the hydrogenation of liquid fats in 1901, creating what later became known as trans fats, leading to the development of the global production of margarine and vegetable shortening. [citation ...
Shutterstock By Toni Clarke WASHINGTON -- The U.S. Food and Drug Administration on Tuesday made good on its proposal to effectively ban artificial trans fats from a wide range of processed foods ...
Hydrogenation is a chemical reaction between molecular hydrogen (H 2) and another compound or element, usually in the presence of a catalyst such as nickel, palladium or platinum. The process is commonly employed to reduce or saturate organic compounds. Hydrogenation typically constitutes the addition of pairs of hydrogen atoms to a molecule ...
Seafood chain Long John Silver's recently announced that its entire menu now has zero grams of trans fat due to a transition from partially hydrogenated cooking oils to 100 percent soybean oil in ...
