How to Tell if Coconut Oil Is Bad?

Coconut oil takes a long time to go bad, and you can easily spot it when it does. A bad coconut oil begins to change both in color and smell. The taste also alters if the oil goes bad.

Read further to look at the signs of spoilage:

1. Its color has changed

Pure coconut oil is transparent, whereas solid oil is white. If your oil displays any color other than white, like yellow or brown, get rid of it.

2. It smells rancid

A virgin (unrefined) coconut oil has a coco-nutty aroma. But if the oil (refined) is solid, it will not have any smell. Refined coconut oil is also the one used mostly in cooking. So, the oil is rancid if your coconut oil smells bitter or has a chemical smell. Once the oil loses its nutty smell, throw it away.

3. It tastes bitter or sharp

In contrast to unrefined coconut oil, refined coconut oil may have a more robust coconut flavor. So, if the coconut oil tastes sour or rancid, it’s no good. Make sure it’s thrown away, and a new one is bought.

4. It has black spots or any other organic growth

The presence of mold or fat can identify rancid coconut oil. You can find mold or fat particles on the surface or floating inside the oil. Once you spot molds, the oil becomes inedible and must be thrown away.
