How Can You Tell if Tahini Is Bad?

How to tell if tahini is bad

You must trust your taste, smell, and sight to distinguish between a rancid and good Tahini paste. Below are some spoilage signs that can help you know when your Tahini paste has gone bad.

Rancid Smell

The oil that floats on the surface of the Tahini paste is supposed to preserve the paste below it. But, when the condiments are exposed to air and oxygen, the oxidation process starts, developing a rancid smell with time.

If you experience a soapy, bitter, or metallic smell in your Tahini paste, discard it as it is a sign of spoilage.
