Additives in food are as ubiquitous as they are nebulous. In our PrimaFoodie Ingredients Spotlight, we investigate common food additives to discover their origin, use, and purpose—because even when something is edible, that doesn’t mean it’s healthy or necessary.

What is Caramel Coloring?

Caramel coloring (also referred to as caramel color) is an edible brown food additive made by heating a variety of carbohydrates, such as corn, high fructose corn syrup, various types of sugar, or malt syrup.

What is the purpose of Caramel Coloring?

As its name suggests, caramel coloring gives foods and beverages a brown or caramel-like color. While the raw finished product does have a slight burnt-like caramel flavor, its main use is to provide color rather than taste.

One of the most widely used substances, caramel coloring has been a popular additive of numerous mass food manufacturers, including Coca-Cola, for more than 150 years. 

Where is Caramel Coloring found?

The wild thing about caramel coloring is just how widely used it is. Turn over any sugary mass-produced drink or snack, and there’s a high chance it contains this additive. 

The most common foods (and food-like substances) that contain caramel color include:

• Brown-colored soda, such as cola and root beer

• Fruit and vegetable juice, such as prune and apple juice

• Beer, cider, and wine

• Jam and jelly

• Bread

• Crackers

• Packaged baked goods

• Gravy 

• Condiments, including mustard

• Soy sauce, Worcestershire sauce, and other sauces

• Candy, including chocolate and licorice

• Bottle tea and coffee

Is Caramel Coloring Bad?

First thing first: Caramel coloring sounds harmless because of its name. (Isn't it just heated sugar?) But a deeper look at this additive, which is made from heating and manipulating various carbohydrates, shows there’s reason to pause.

Every manufacturer creates its caramel coloring a bit differently. As we noted, some heat high fructose corn syrup, a highly processed substance widely reported to cause metabolic issues. Others may use sugar or malt syrup. Depending on the main heated ingredient, some variations of caramel color contain a byproduct called 4-methylimidazole (4-MeI), which has been under scrutiny for more than two decades because of its potential carcinogenic effects. 

In 2007, the National Toxicology Program released a study examining the impact of 4-MEI on rats. While its potential carcinogenicity was deemed "inconclusive," this still caused many food sleuths to fight to ban the substance. More recently, in 2020, the National Toxicology Program published the results of another study on 4-MEI and rats to see if exposure to the chemical caused any developmental or reproductive harm. The FDA states that this study "showed reproductive and developmental effects in male and female rats at the levels tested."

For the past 10 years, California has required any manufacturers offering a product with more than 29 micrograms of 4-MeI to label it as a potential health warning. Coca-Cola reformulated its product to avoid having to place such a warning on its packaging.

The PrimaFoodie Take 

As we always do with ingredients, we went through our checklist for caramel coloring: Is this ingredient processed? Does it offer nutritional value? Is it necessary? Where does the research point? Caramel coloring is highly processed, offers zero health benefits, and is linked to carcinogenicity in studies. 

Considering all of this, we avoid foods with caramel coloring by all accounts. This additive is linked to too many concerns to warrant any place in our diets. Plus, any additive that manipulates a food's color also attempts to manipulate consumers because it makes food seem more appealing. 

One of the greatest ways we can fight against food manufacturers creating substances that are bad for our health is to read our labels, avoid additives, and thus break the demand.
