History of Natural Food Colors

The use of coloring agents in food can be traced back thousands of years to practices of ancient civilizations. However, it wasn't until the 19th century that synthetic dyes began being mass produced and used commercially in place of natural ingredients. By the early 20th century, artificial coloring had become widespread in the processed food industry due to their low cost and uniform coloring properties.

Health Concerns with Synthetic Dyes

In the second half of the 20th century, health concerns began to arise regarding the safety of certain synthetic food dyes. Studies found dyes like Tartrazine (FD&C Yellow 5) and Sunset Yellow (FD&C Yellow 6) could be linked to behavioral issues in children. Other dyes such as carmoisine (E122) were thought to possibly cause cancer in animal studies. By the 1990s, several countries had begun banning certain artificial dyes or placing warning labels on Natural Food Colors containing them.

Moving Toward Natural Alternatives

To address consumer demand for cleaner labels, food producers started exploring alternatives to artificial colors derived from petroleum products or coal tars. Companies looked to natural plant and mineral sources that had been used for centuries before the rise of synthetic dyes. Colors approved by the FDA as generally safe include anthocyanins from berries, carotenoids from vegetables, and chlorophyll from green plants.
