Adding a substance to make food unpalatable

Technical

Denaturation is the process by which foods or liquids are made unpleasant or dangerous to consume; it is done by adding a substance known as a denaturant. Aversive agents—primarily bitterants and pungent agents—are often used to produce an unpleasant flavor. For example, the bitterant denatonium might be added to food used in a laboratory, where such food is not intended for human consumption.
