This process converts the liquid oils into solids and increases the shelf life of the food. These are used in some of the margarine, snack items and other foods. These trans fats remain solid at room temperature. These are responsible for raising the bad cholesterol in the blood which will be responsible for the blocking the blood vessels. Thus is responsible for cardiovascular diseases.
