| Hydrogen is also used by the food products industry to convert liquid oils to solid fats in a process known as hydrogenation. |
| Due to its natural semi-solid consistency, palm oil does not need to go through the hydrogenation process which creates trans-fatty acids. |
| During hydrogenation some of the unsaturation is converted to the trans configuration, with like groups on opposite sides of the plane. |
| A good example is the push to develop stable new oilseed varieties that reduce or eliminate the need for hydrogenation. |
| For example, nickel is a catalyst in the hydrogenation of vegetable oils. |
| Catalytic hydrogenation adds six hydrogen atoms to produce cyclohexane, a colorless liquid with the properties of an alkane. |
