With so many different types of natural colors, choosing the right one for your meat alternative application can feel overwhelming. Whether you’re creating plant-based burgers, sausages, or mince, there are some important factors to consider when choosing a natural color. We’ve broken down the top 5 considerations when coloring meat alternatives to make your color decision easier.
1. Base Color
The first thing you’ll need to consider is the target color for your plant-based protein. And one of the main things that can impact this is the base color of your product. Depending on the type of meat alternative you’re trying to create, there are different proteins used in plant-based alternatives that all have different undertones. For example, soy protein is an off-white color, while pea protein is a light greenish brown, as seen in the photo below. You may need to change dosage levels or use blends to overcome the background color of these proteins and achieve your target shade.
It’s also important to choose the correct form of color. Natural colors come in both water and oil-soluble forms, as well as powder and liquid. For most meat alternatives, water-soluble colors are suitable. But oil-soluble colors should be used if the product has a particularly high fat content, or you are coloring fat inclusions.
You’ll also need to determine what you want your product to look like when it reaches the consumer. Raw to cooked, pre-cooked, and frozen are the most common forms of meat alternatives. Each form requires consideration as to which shade will best suit the desired end appearance and look the most appealing to consumers. For this, you’ll need to consider both the type of meat alternative you’re trying to mimic (chicken, beef, lamb, etc.) and the flavor you’re using (ex: herb, BBQ, chipotle). Natural colors like turmeric, beta-carotene, annatto, and beet provide yellow tones for chicken and turkey-type products, while Naturbrown® ingredients can be used for the light tan to dark brown shades of pre-cooked options. Blends of these products can be used to create the perfect custom shade for your plant-based protein application.
If you’re creating a plant-based “beef” product, customers will expect it to look like raw beef. Natural colors like beet work well for these pink to red hues. Many meat alternatives will require color blends to give them a more realistic raw to cooked appearance. This can be achieved with additional colors like paprika and caramel.
3. Thermal Processing
The thermal processing conditions your product is exposed to before it reaches the consumer will also impact your color selection. Is it a raw product that is cooked later by the consumer, or is it a pre-cooked product where the color change is controlled by manufacturing? If you want the color of your product to stay consistent through processing and consumer cooking, as for a pre-cooked item, you’ll want to choose heat stable colors like class I caramels or Naturbrown® ingredients. Or, if you need it to change in color as the consumer is cooking it, like with a raw to cooked product, you’ll want to choose reds that are prone to fading with heat, like beet. The thermal heat your product is exposed to in the manufacturing process is critical to selecting the right natural colors to achieve your desired end look.
4. Packaging, Storage, & Shelf Life
It’s important to consider your product’s packaging, storage conditions, and shelf life. Plant-based proteins are typically neutral in pH and are stored in the refrigerator or freezer section of the supermarket, so a wide variety of colors are available. Freezer and refrigeration temperatures are ideal for natural color stability. If the product is refrigerated, it will also be on the shelf for a shorter amount of time than a product that’s frozen, but it may have clear packaging, so be sure to choose colors that have good light stability.
5. Label Declarations
Since meat alternatives are popular with vegans and vegetarians, you’ll need colors that meet these claims. In these cases, you would need to select red beet color or another color blend as opposed to something like carmine. Additional label claims like kosher, halal, organic, and non-GMO project verified can also impact your color selection. The best way to find a color that meets your required label claims is to work with your natural color supplier.
