Rancidity: Why Do Foods Turn Rancid?

The video explains rancidity, a process that causes food spoilage due to chemical reactions involving fats and oils. It describes the chemical structure of fatty acids and the steps of rancidity reactions, including initiation, propagation, and termination. The video also covers two types of rancidity: oxidative and hydrolytic, and discusses factors like oxygen, microorganisms, and temperature that affect rancidity. Finally, it suggests methods to prevent rancidity, such as using antioxidants and proper storage.

Explain the role of oxygen in the rancidity process.
