Description

Imagine changing a substance by adding hydrogen to it - that's the basic idea here. It's a chemical reaction where hydrogen is added to another substance. You might hear about it most often when talking about oils, like turning liquid vegetable oil into a more solid fat used in margarine or shortening. This process changes the structure of the molecules, often making them more stable and raising their melting point.

But hydrogenation isn't just for food. It's also an important step in many industrial processes, including petroleum refining and making some chemicals. Think of it as a way of changing a substance by adding tiny hydrogen atoms so it behaves differently. In food science, it is one way unsaturated fats can be changed into more saturated fats.

Examples

  1. 1

    Food production

    The factory uses hydrogenation to make margarine from vegetable oil.

  2. 2

    Trans fats

    Partial hydrogenation can create trans fats, so many food companies have stopped using it.

  3. 3

    Chemistry class

    In chemistry class, we learned that hydrogenation often needs a metal catalyst.
