Rancidity in fats is caused by which of the following?

Explanation:
Rancidity in fats comes from chemical changes in the fat itself, typically starting with hydrolysis that releases free fatty acids. When triglycerides are broken down, free fatty acids form, and these compounds contribute to the off-flavors and odors associated with rancidity. They’re also more prone to further oxidation, which accelerates the spoilage process. Among the options given, the free fatty acids best explain the development of rancidity. Proteins, vitamins, and minerals do not cause rancidity in fats; they don’t generate the characteristic rancid notes. Preventing rancidity focuses on limiting moisture and oxygen exposure, keeping fats cool, and sometimes adding antioxidants to slow oxidation.
