Anthocyanins

Anthocyanins (CAS 11029-12-2), also sourced and traded as grape anthocyanins, are water-soluble plant pigments extracted primarily from grape skins, berries, and other dark-colored botanical sources.

They function as natural colorants and antioxidant actives across food, cosmetic, and nutraceutical manufacturing. In food and beverage production, they deliver stable red-to-purple hues in confectionery and dairy products.

These pigments are used in soft drinks and functional foods without synthetic dyes. Nutraceutical and dietary supplement formulators incorporate them as antioxidant actives in capsules, tablets, and standardized botanical extracts.

Cosmetic manufacturers use grape anthocyanins in serums, creams, and color cosmetics where both pigmentation and antioxidant stabilization of the finished formula are required for high-quality results.

In printing and packaging, they serve as bio-based colorant inputs for pH-sensitive or natural-origin ink systems. Anthocyanins are supplied as spray-dried powders, liquid extracts, and concentrated solutions.

Powder is the most common commercial form for industrial handling. Standardized grades are available specifying anthocyanin content by percentage, typically characterized against cyanidin-3-glucoside equivalents.

Food-grade and USP-referenced specifications are the most commonly requested, with organic-certified material available from select sources to meet specific industrial manufacturing requirements.
