How can sunflower oil be hardened to form margarine?
Well, darling, sunflower oil can be hardened to form margarine through a process called hydrogenation. This involves bubbling hydrogen gas through the oil at high temperatures in the presence of a catalyst. The unsaturated fats in the oil become saturated, creating a solid fat like margarine. So, there you have it, margarine in a nutshell...or should I say, in a sunflower shell?
