Naturally, food color may degrade due to processing, storage, or environmental conditions, leading to the need for added colorants. Food colorants are substances used to restore or enhance the appearance of food and beverages, making them more visually appealing and appetizing. They help in improving product identity, standardizing food appearance, and compensating for color loss during food processing. Food colorants have been used for centuries, with early civilizations utilizing plant extracts, spices, and minerals to enhance the appeal of food. Over time, the food industry has developed synthetic alternatives that offer better stability, cost-effectiveness, and a wider range of color options. However, concerns over the safety of synthetic colorants have led to increasing consumer preference for natural alternatives.

Natural Food Colorants

Natural food colorants are pigments derived from plants, animals, and minerals, widely used to enhance the visual appeal of food and beverages. These colorants are considered safer and healthier compared to synthetic alternatives, as they often contain bioactive compounds with potential health benefits. Common natural colorants include carotenoids (from carrots and tomatoes), anthocyanins (from berries and red cabbage), chlorophyll (from green leafy vegetables), curcumin (from turmeric), and betalains (from beetroot). Despite their advantages, natural colorants face challenges such as instability to heat, pH, and light, which can limit their application in processed foods.

Due to increasing consumer demand for clean-label products, natural food colorants are becoming more popular in the food industry.
