Colorants, also known as food colors or food dyes, are substances used to enhance or alter the color of food and drinks. They can maintain or improve food appearance, especially when natural colors may fade during processing or storage. The food industry primarily employs two categories of colorants: natural and synthetic. Commonly used colorants are Anthocyanins, Beet Root Red, Black Carrot Purple, Gardenia Blue, Gardenia Green, Lutein, Lycopene, Paprika Oleoresin, Zeaxanthin, etc.
Food colorants, pivotal for enhancing the appearance and appeal of food and beverages, are categorized into natural and synthetic types, each with distinctive sources and applications.
Natural Colorants

Allura Red (Red 40): A popular red dye used in candies, beverages, and processed foods.
Tartrazine (Yellow 5): Offers a bright yellow color, found in desserts, candies, and snacks.
Brilliant Blue FCF (Blue 1): A common blue dye used in beverages, ice creams, and processed foods.
Sunset Yellow FCF (Yellow 6): Produces an orange hue, used in snacks, sauces, and beverages.
