Which of the following is a typical indicator of rancidity in dairy fat products?

Explanation:
Rancidity in dairy fats is driven by the breakdown of fats (lipolysis), which releases free fatty acids into the fat. As lipase activity and other hydrolytic processes proceed, the free fatty acid content increases, and the product often develops off-flavors and odors associated with rancidity. This rise in free fatty acids is a classic and reliable indicator of rancidity in dairy fat products. Lactose levels don’t reflect rancidity in fat; protein changes aren’t a direct measure of lipid rancidity, and moisture changes relate to drying or water activity rather than fat spoilage.
