Description

Diadinoxanthin is a naturally occurring xanthophyll pigment found in various microalgae and phytoplankton. This compound plays a critical role in photoprotection, helping to dissipate excess light energy and prevent oxidative damage in photosynthetic organisms. It is primarily utilized in the nutraceutical, cosmetic, and research sectors for its antioxidant properties and as a biochemical marker.

Application

• Nutraceutical Ingredient: Incorporated into dietary supplements for its antioxidant and potential anti-inflammatory benefits.
• Cosmetic Formulations: Used in skincare products for its photoprotective and anti-aging properties.
• Biochemical Research: Serves as a vital reagent and standard in studies of photosynthesis, algal physiology, and pigment metabolism.
• Aquaculture Feed Additive: Enhances the pigmentation and health of farmed fish and crustaceans.
• Natural Food Colorant: Provides a yellow to orange hue in specialized food and beverage applications.
• Phytoplankton Analysis: Used as a diagnostic pigment in oceanography and environmental monitoring to identify and quantify algal populations.
