What Are Food Pigments?
What are synthetic food pigments, and why are they used in food and beverage items? Food pigments are chemical dyestuffs that provide color to food products. These pigments could be natural or synthetic and are widely used to enhance food’s color, taste, and appeal. Natural food pigments are derived from natural sources, including green vegetables, fruits, plants, and other organisms.
On the other hand, synthetic food pigments are produced synthetically using coal-tar or petrochemical reactions between two or more compounds, which are carried out in a laboratory. Furthermore, most color pigments, especially those derived from naturally occurring sources, do not require FDA Batch Certification and can blend with other colors to create unique shades and opacity.
Types of Pigments in Food
Food pigments impart color to improve the visual appearance of food products. They also make products more tasty, adding necessary nutrition and health benefits. Here are the following types of food pigments:
- Chlorophyll: This green pigment is naturally derived from plants and offers nutrients like Kale and Spinach. It is essential for the application of photosynthesis.
- Carotenoids: Color pigments like beta-carotene and lycopene, which are derived naturally, give carrots and tomatoes their distinct yellow, orange, and red hues and multiple health benefits.
- Anthocyanins: Water-soluble pigments impart more beautiful purple, blue, and red colors in grapes, cabbage, and berries. This type of food pigment offers rich antioxidant properties.
- Betalains: These pigments are derived from vibrant beets, certain cacti, and more stunning red and yellow colors. They are best known for their multiple health benefits.
- Melanoidins: These pigments help create the delicious browning that results from the Maillard reaction occurring during cooking when proteins and sugars interact. They are widely used in foods such as coffee and toast.
