Description

Cyanidin is a natural anthocyanidin pigment, a key plant secondary metabolite responsible for red, purple, and blue hues in many fruits and flowers. Its potent antioxidant and free radical scavenging properties make it a highly valuable bioactive compound for research and product development. This compound is essential for manufacturers and researchers in the nutraceutical, food & beverage, cosmetic, and pharmaceutical industries seeking natural colorants and functional ingredients.

Application

• Natural Food & Beverage Colorant: Used to impart stable red to purple colors in juices, yogurts, confectionery, and alcoholic beverages as a clean-label alternative to synthetic dyes like FD&C Red No. 40.
• Nutraceutical & Dietary Supplements: Formulated into capsules, tablets, and powders for its well-documented antioxidant benefits and support for cardiovascular and cognitive health.
• Cosmetic & Personal Care: Incorporated into skincare serums, creams, and lotions for its anti-aging and skin-protective properties against environmental stressors.
• Pharmaceutical Research: Serves as a reference standard and active pharmaceutical ingredient (API) intermediate in studies focusing on inflammation, diabetes, and cancer.
• Analytical & Diagnostic Reagents: Employed as a standard in HPLC, LC-MS, and spectrophotometric methods for quantifying anthocyanin content in agricultural and food products.
• Plant & Agricultural Research: Used in studies of plant physiology, genetics, and biochemistry to understand pigment biosynthesis and stress responses.
