\nThe correct answer is hydrogen gas.
\n<\/section>\n
\nLiquid vegetable oils are typically unsaturated fats, meaning they contain carbon-carbon double bonds. To convert these liquid oils into solid or semi-solid fats like margarine, hydrogen gas is added across the double bonds in the presence of a catalyst (usually nickel, palladium, or platinum). This process is called hydrogenation.
\n<\/section>\n
\nPartial hydrogenation can lead to the formation of trans fats, which have been linked to negative health effects. Modern hydrogenation processes aim to minimize trans fat formation while achieving the desired consistency.
