What are the disadvantage of rancidity?

Rancidity leads to the deterioration of food quality, resulting in off-flavors, unpleasant odors, and a decrease in nutritional value. It can pose health risks, as consuming rancid fats may lead to digestive issues and the formation of harmful compounds. Additionally, rancidity can result in economic losses for producers and retailers due to spoiled products that are unsellable. Overall, it negatively impacts food safety and consumer satisfaction.
