Advantages and Disadvantages of Natural Food Coloring
In order to enhance the aesthetic and sensory appeal of foods, especially confectionery and beverages, food coloring is often used. While artificial food colors are readily available in the market, they can have negative health effects. On the other hand, natural food colors, which are extracted from plants and animals, are considered safer for consumption. However, they also have their own set of advantages and disadvantages:
- Safe for consumers’ health
- Easy to use
- Natural colors contain a high amount of vitamins and minerals
- Produced in limited quantities
- Short shelf life
