• In this process, the vegetable oils are hydrogenated in the presence of a catalyst under optimum conditions of temperature and pressure.
• The unsaturated fatty acids are converted into saturated fatty acids.
• The liquid oil changes into semi solid and solid fat.
Mention the disadvantages and advantages of hydrogenation.
• The unsaturated fatty acids get converted into saturated fat which is harmful.
• Trans fatty acids are produced which are more atherogenic than even saturated fatty acids.

• Solid ghee like consistency is preferred for certain types of cooking in India.
What are trans fatty acids?
Trans fatty acids are geometric isomers of naturally occurring cis-unsaturated fatty acids. These are produced by
• Partial hydrogenation of PUFA in vegetable oil
• Repeated reheating of oil for frying
Why are trans fatty acids harmful?
• They raise the plasma level of LDL cholesterol.
