1. Understanding Food Coloring Shelf Life
How long does food coloring typically last before it expires?
Food coloring generally has a long shelf life, often lasting for several years beyond the “best by” date. Factors such as the type of food coloring (liquid, gel, or powder) and storage conditions significantly influence its longevity. Liquid and gel food colorings usually contain water, glycerine, and preservatives like sodium benzoate, which help extend their shelf life. Powdered food coloring, containing no liquid, typically lasts the longest.
1.1. Liquid Food Coloring
