What do “unprocessed” and "hydrogenated" mean?

"Unprocessed” means that the refined fat or oil has undergone no changes in its nature. “Hydrogenated” oil or fat means that hydrogenation has been performed, i.e. a process designed to give an appropriate texture to the final product. To make margarine spread well, it has to be hydrogenated, resulting in the saturation of the fatty acids.
