Description

Peonidin is a natural anthocyanidin, a type of plant pigment responsible for the vibrant red, purple, and blue colors in many fruits and flowers. This compound is of significant commercial interest due to its potent antioxidant properties and its role as a key colorant and nutraceutical ingredient. It is primarily utilized by manufacturers in the food and beverage, dietary supplement, cosmetic, and pharmaceutical industries for applications ranging from natural food coloring to functional health products.

Application

• Natural Food & Beverage Colorant: Used to impart stable red and purple hues to juices, soft drinks, confectionery, yogurts, and other processed foods.
• Dietary Supplements & Nutraceuticals: Incorporated into capsules, tablets, and powders for its well-researched antioxidant and potential health-promoting benefits.
• Cosmetic & Personal Care Formulations: Acts as a natural coloring agent and bioactive component in skincare products, lipsticks, and hair dyes.
• Pharmaceutical Research: Serves as a reference standard and an active pharmaceutical ingredient (API) intermediate in drug discovery and development.
• Analytical & Laboratory Use: Employed as a high-purity standard for HPLC, LC-MS, and other analytical methods in quality control and research laboratories.
• Plant Biochemistry Studies: Used in academic and industrial research to study anthocyanin biosynthesis, plant physiology, and metabolic pathways.
