What Is Chili Red and How Is It Used as a Natural Food Colorant?

Chili Red, also known as Capsanthin or Capsorubin, is a natural carotenoid pigment extracted from red chili peppers (Capsicum annuum). It provides a bright red to orange shade and is widely used in food, cosmetics, and animal feed as a safe and natural alternative to synthetic dyes. With its strong coloring ability and antioxidant properties, chili red is highly valued in both traditional cuisines and modern industrial applications.
