Canthaxanthin[edit]
Canthaxanthin is a carotenoid pigment that is widely used in the food and cosmetic industries. It is a naturally occurring compound found in various plants and animals, contributing to the red and orange colors in nature.
Chemical Structure and Properties[edit]
Canthaxanthin is a xanthophyll, a type of carotenoid that contains oxygen. Its chemical formula is C40H52O2. The molecule consists of a long chain of conjugated double bonds, which is responsible for its color and antioxidant properties. The presence of these double bonds allows canthaxanthin to absorb light in the visible spectrum, giving it a characteristic orange-red hue.
Sources[edit]
Canthaxanthin is found in nature in a variety of sources. It is present in certain species of fungi, bacteria, and algae. It is also found in the feathers of some birds, such as flamingos, and in the shells of crustaceans. In the food industry, canthaxanthin is often used as a color additive in products like salmon, trout, and egg yolks to enhance their appearance.
Uses[edit]
Food Industry[edit]
In the food industry, canthaxanthin is used as a colorant to improve the visual appeal of various products. It is approved for use in many countries and is often added to animal feed to enhance the color of farmed fish and poultry.

Medical Applications[edit]
Research is ongoing into the potential health benefits of canthaxanthin, particularly its antioxidant properties. However, excessive consumption of canthaxanthin can lead to a condition known as canthaxanthin retinopathy, where crystals form in the retina, potentially affecting vision.
Safety and Regulations[edit]
The use of canthaxanthin is regulated by various health authorities around the world. The European Food Safety Authority (EFSA) and the U.S. Food and Drug Administration (FDA) have set limits on the acceptable daily intake of canthaxanthin to ensure consumer safety. It is important for manufacturers to adhere to these guidelines to prevent adverse health effects.
