Replacement Strategies for Caramel Coloring
Increasingly, more of our customers are asking us to help them remove caramel color from their current formulations. Sensient consumer research indicates about more than one third of the general population are concerned with the presence of caramel coloring and seek to avoid it in their everyday foods and beverages. This uneasiness most likely stems from negative publicity around California’s Prop 65 and similar headlines. Since ingredient lists do not differentiate between any of the Classes I-IV, consumers just seem to avoid the color altogether.
Additionally, there seems to be some controversy over caramel coloring amongst regulatory bodies. To avoid uncertainty, many food and beverage brands are proactively choosing to replace caramel color with an alternative option.
A Look at Caramel Coloring
As caramel is one of the most widely used colorants, the intent to replace is prevalent across a broad range of applications, including cakes, cremes and icings, breads, cookies, plant-based meats, beverages like teas, coffees, and soda, pet food, alcoholic beverages, bakery mixes, soups and sauces, etc.
While caramel has low tinctorial strength, the high usage rate typically required is offset by the low cost. Additionally, caramel has other attractive features including:
- Very good heat stability
- Few off-notes that restrict usage level
- Stable color across a wide pH range
- Exceptionally good light stability
From a technical standpoint, there are not many negatives when it comes to performance or cost-in-use for caramel.
Blending Natural Colors to Replace Caramel
One common approach to replace caramel coloring would be to use a combination of a natural red like beet, a natural yellow such as beta-carotene, and a natural blue vegetable juice. This blend produces excellent brown shades assuming the pH is above 4. Spirulina could be a blue component option dependent on its regulatory permittance. Additionally, there are other natural reds and yellows that could be in the brown formulation—all reliant on target shade and application environment. For example, if there is a heat step involved in your processing, spirulina is not stable, and some red anthocyanins shift to purple which would darken or blacken your end product color. Fortunately, Sensient has a novel blue vegetable juice that works very well in this scenario and a heat-stable beet.
There is one drawback to this approach. Natural blue vegetable juice is generally more expensive than other natural color sources, so cost-in-use for this strategy tends to be a bit higher when compared to costs associated with caramel.
Another Approach to Replacing Caramel Coloring: Natural Brown Vegetable Juice
Our team has found quite a lot of success employing our Sienna™ natural brown fruit juice. It has many of the same advantages as caramel color and provides very appealing brown shades. It is an ideal replacer for Class I or Class II caramel. Sienna is stable across an extremely broad pH range and will stand up to heat and light.
From a usage standpoint, the Sienna fruit juice is very cost-efficient, so price is generally not a concern. Flavor off-notes have been minimal; we have hardly
experienced any issues in a majority of formulations. It really depends on the application, the level of flavor, and obviously the desired shade.
Final Thoughts on Caramel Replacement Strategies
One of the most interesting approaches to replacing caramel has been to use the Sienna™ fruit juice in combination with other ingredients in our natural brown portfolio to reduce cost and improve heat stability. This solution has produced some very good results, including dark brown options.
Depending on the application and base material color, color experts may be able to devise tailored solutions for achieving natural brown that leverage low-cost natural colors while still avoiding Prop 65 restrictions.
