Trans fats are an impurity of the hydrogenation process. The momentary addition of one hydrogen atom to the double bond followed by a rotation of the chain about the temporary single bond linkage in the fat molecule and loss of this hydrogen atom back to the catalyst permits the reformation of a double bond in the trans arrangement.
