Trans fats can be created by the process of hydrogenation.

Question

BlackTom AI · Accepted Answer

Trans fats can be created by the process of hydrogenation.
Option 1: True. Hydrogenation, especially partial hydrogenation, adds hydrogen to unsaturated fatty acids and can convert some cis double bonds into trans double bonds, producing partially hydrogenated oils that contain trans fats. This is a well-established method used in the food industry to increase shelf life and modify texture. The presence of trans fats arises primarily from incomplete or partial hydrogenation, not from complete hydrogenation, which would produce mainly saturated fats with few or no trans fats.
Option 2: False. Saying that trans fats cannot be created by hydrogenation would ignore the chemistry of partial hydrogenation, where cis double bonds can isomerize to trans configuration. While complete hydrogenation reduces the number of double bonds and yields mostly saturated fats, partial hydrogenation intentionally preserves some double bonds and yields trans fats, making this statement inaccurate.
In summary, the mechanism of partial hydrogenation explains why trans fats can be formed during processing, whereas full hydrogenation minimizes trans fat formation and yields saturated fats. This distinction helps clarify why hydrogenation is associated with trans fats in culinary and industrial contexts.
