Description

Bacterioruberin is a naturally occurring C50 carotenoid pigment, renowned for its potent antioxidant properties and distinctive red-orange color. This compound is of significant commercial interest due to its superior stability and bioactivity compared to many other carotenoids, offering enhanced performance in demanding applications. It serves as a critical ingredient for manufacturers in the nutraceutical, cosmetic, and food & beverage industries seeking natural, high-value functional additives.

Application

• Nutraceuticals & Dietary Supplements: Utilized as a powerful antioxidant ingredient in capsules, tablets, and functional food formulations to support cellular health and combat oxidative stress.
• Cosmetics & Personal Care: Incorporated into anti-aging serums, creams, and lotions for its skin-protective benefits and as a natural colorant.
• Food & Beverage Coloring: Serves as a natural, stable alternative to synthetic dyes (e.g., Red 40) in products like beverages, dairy, confectionery, and sauces.
• Aquaculture & Animal Feed: Used as a feed additive to enhance the coloration of farmed fish (e.g., salmon, trout) and poultry, improving product marketability.
• Pharmaceutical Research: Employed in biochemical research and as a reference standard due to its unique structure and biological activity.
• Advanced Materials: Investigated for use in natural dye-sensitized solar cells (DSSCs) and other bio-inspired photonic applications.
