With so many different types of natural colors, choosing the right one for your snack application can feel daunting. Whether you’re creating chips, crackers, popcorn, or pretzels, there are some important factors to consider when choosing a natural color. We’ve broken down the top 5 considerations when coloring snacks to help you make the best decision.
1. Delivery System
The first factor to consider is your color delivery system. When or where will the color be added? If you’re adding it directly to the base of crackers, tortilla chips, or extruded snacks, you have the option of using a powder for dry blend mixtures or liquid for a wet dough. In both cases, you’ll need heat stable colors, such as annatto, turmeric, paprika, and copper chlorophyll[in] to provide the best results after the high heat of baking, extruding, or frying. Both oil and water-soluble colors are available in a wide variety of popular snack shades to fit your formulation.
You might also want to add the color to the snack seasoning or slurry that’s sprayed or coated on the outside towards the end of the process. Heat stable powder colors can be coated on fried snacks just out of the oil, while colors with lower stability can be added to fatty slurries and then sprayed onto the snack. Knowing how you plan to deliver the color helps determine the best color form for the snack in question.
2. Processing Conditions
How a snack is processed can also make a difference when choosing a natural color. Is it going to be baked, fried, or extruded? If it’s baked, are you using a batch or a continuous oven? What does the cooling process look like? Natural colors like annatto, paprika, and beta-carotene are ideal for snack applications since they can withstand high temperatures. Other colors, such as beet, appear most vibrant when added to seasonings or coatings where they aren’t exposed to high heat conditions.
3. Flavor/Target Shade
With so many new and different flavors on the market, having a target hue in mind for your snack’s final appearance is key. This helps determine if your shade can be achieved with a single color – like annatto – or if a blend is needed to get the right hue. There may be a product already on the market with a hue you are trying to match – either naturally or synthetically colored – or maybe you’re developing a brand-new snack product, with a flexible range of acceptable hues you’ve selected from different Pantone swatches. And if you need help hitting that perfect shade, we can help you with the color matching process.
Different snack bases can also result in the appearance of the final color in the end product. Chickpea, potato, and corn flours all have different undertones that will require different dosage rates to achieve similar colors, as seen in the image below.
4. Regulatory & Commercial Limitations
Understanding where and how your snack product is going to be marketed and sold is critical when selecting natural colors. Every country has their own regulatory requirements, and that can limit which colors, and how much of them, can be used. For example, carbon black is not permitted for use in any food application in the United States but has been approved for use in other regions.
Even if a natural color is permitted for use in a certain region, there may still be limitations surrounding how it is used.In some regions, natural colors, like annatto and carmine, have maximum use limits by specific application types.Other products may require specific regulatory certifications, such as Kosher, Halal, Certified Organic, or Non-GMO Project Verified that require additional care when deciding on the right natural color.
5. Storage & Packaging
How will your snack product be packaged and stored? The type of packaging is a key factor when determining which natural colors will stay vibrant during the entirety of the snack’s shelf life. Some colors are more light-stable than others, so if the packaging is clear or has a window, be sure to select colors with good light stability, such as beta-carotene and annatto as opposed to turmeric, which performs best in opaque packaging where it’s protected from light.
It’s also important to determine your snack product’s expected shelf life and storage conditions. How long is the product expected to last once it’s packaged and at what temperature will it be stored? Knowing this information up front will help determine the best natural colors to use.
