Since these oils are liquid at room temperature (unlike traditional baking fats, such as butter and lard), manufacturers figured out a way to use hydrogen atoms to rearrange the chemical structure, turning the product from a liquid to a solid.

Trans fats are artificially created through a process called hydrogenation, which uses hydrogen, pressure and heat to change the chemical structure of vegetable oils from liquid to semi-solid.

Hydrogenated fats are vegetable oils that are liquid at room temperature but are bombarded with hydrogen particles (hence the term «hydrogenated») changing the chemical composition from unsaturated to saturated fats that create a solid butter - like texture at room temperature.
