This article will explore the science behind food coloring expiration, how to determine if your food coloring is still good, and safe practices for using and storing it.

Understanding Food Coloring Expiration

What Causes Food Coloring to Expire?

Food coloring, whether liquid, gel, or powder, contains colorants that can break down over time due to exposure to light, air, and temperature fluctuations. This degradation affects the intensity and shade of the color. Liquid food coloring tends to expire faster than gel or powder due to its higher water content, making it more susceptible to microbial growth. Powdered food coloring, when stored correctly in a cool, dry place, can last significantly longer.

How to Tell If Food Coloring Is Bad?

While the “best-by” date provides a general guideline, it doesn’t always indicate spoilage. Here are a few signs your food coloring has gone bad:

Mold: Any visible mold growth is a clear sign to discard the food coloring.
Off-odor: A strange or unpleasant smell indicates spoilage.
Separation: For liquid food coloring, separation or cloudiness may signal degradation.
Dull color: If the color appears significantly faded or dull, it’s likely past its prime.

If you’re unsure, it’s always best to err on the side of caution and discard the food coloring.
