Natural coloring refers to the use of plant-based or mineral-based substances to add color to various products, such as textiles, cosmetics, and food. Unlike synthetic dyes, which can contain harmful chemicals, natural coloring is derived from sources like fruits, vegetables, flowers, and earth minerals. This method is often preferred for its eco-friendliness and safety. In the food industry, natural coloring enhances the visual appeal of products without artificial additives. Common examples include beet juice for red, turmeric for yellow, and spirulina for green. As consumers become more health-conscious, the demand for natural coloring continues to grow, promoting sustainable practices.
