Rancidification

Rancidification happens when food gets stinky and yucky. This usually happens when food has fats in it and gets exposed to things like air, heat, and light. When food goes through rancidification, it starts to smell bad and taste weird. It's important to make sure you don't eat rancid food because it can make you sick. So, always make sure to check the expiration date on your food and pay close attention to any weird smells or flavors.
