Fat hydrogenation - Wikiped
Fat hydrogenation is the process of combining fat — typically, vegetable oils — with hydrogen, in order to make it more saturated.. The process is typically carried out at very high pressure, with the help of a nickel catalyst (that is removed from the final product).. Their partial hydrogenation reduces most, but not all, of these carbon-carbon double bonds.Get a Quote
