Cooking oil is an essential component of many recipes, and it’s often used to add flavor, texture, and moisture to our favorite dishes. However, when cooking oil gets too hot, it can become a recipe for disaster. In this article, we’ll explore what happens when cooking oil gets too hot, the dangers of overheated oil, and how to prevent it from happening in the first place.
The Science Behind Cooking Oil
Before we dive into the dangers of overheated cooking oil, it’s essential to understand the science behind it. Cooking oil is a type of lipid that is composed of triglycerides, which are molecules made up of glycerol and fatty acids. When cooking oil is heated, the triglycerides break down into their component parts, releasing free fatty acids and glycerol.
This process is known as thermal decomposition, and it’s a natural process that occurs when cooking oil is heated. However, when cooking oil is heated too high, the thermal decomposition process can become uncontrolled, leading to the formation of unhealthy compounds and a decrease in the oil’s nutritional value.
