Wiki info

The hydrogenation process involves "sparging" the oil at high temperature and pressure with hydrogen in the presence of a catalyst, typically a powdered nickel compound, such as Raney nickel. Chemically, hydrogenation is the reduction of a carbon-carbon double bond to a single bond, by addition of hydrogen atoms. Since the surface of the metal catalyst is covered with hydrogen atoms, when the double bonds of the unsaturated oil come into contact with the catalyst, it reacts with the hydrogen atoms, forming new bonds with the two carbon atoms; each carbon atom becomes single-bonded to an individual hydrogen atom, and the double bond between carbons can no longer exist. In organic chemistry, unsaturation is considered as a pair of hydrogen atoms missing from the (hypothetical) fully-saturated carbon chain. The level to which an organic molecule is deficient in hydrogen, is called the degree of unsaturation (DoU); as the degree of unsaturation decreases, the oil progresses toward being fully hydrogenated (when DoU = 0). A fully hydrogenated oil, also called a saturated fat, has had all of its double bonds converted into single bonds. If a polyunsaturated oil is left incompletely-hydrogenated (not all of the double bonds are reduced to single bonds), then it is a "partially hydrogenated oil" (PHO). PHOs are the primary dietary source of artificial trans fat in processed foods. An oil may be hydrogenated to increase resistance to rancidity (oxidation) or to change its physical characteristics. As the degree of unsaturation is lowered by full or partial hydrogenation, the oil's viscosity and melting point increase.
