For short-term storage, an airtight container with a lid should be used so that no air can enter the bottle or tube of food coloring.

Make sure to label the containers clearly with the type of food coloring, but also add the expiration date if known.

To be extra cautious, it’s best to check that your food coloring hasn’t started clumping or crinkling before using it in baking or other recipes.
