Yellowing refers to?

Fats turning yellow is a sign of fat oxidation, or oxidative rancidity. In fresh meat, fat is white, but when fats are exposed to air, light, and heat, they break down and produce oxidation products that can give the fat a yellowish color and eventually lead to off-flavors and odors. This color change serves as an indicator that fat quality is deteriorating and the product may be less safe or desirable to eat. Bacterial contamination tends to show other spoilage indicators like off-odors, slime, or surface discoloration that isn’t specifically the yellowing of fat. Age, weight, and sex influence overall carcass characteristics and fat distribution but don’t directly define yellow fat as the sign of oxidative rancidity. Cutting and packing affect handling and surface integrity but don’t cause the intrinsic yellowing of fat.
