Red Rice Red Color Natural Anthocyanin Pigment Extract

Red Rice Anthocyanin Natural Red Pigment

Red Rice Red Color, also known as Black Rice Anthocyanin, is a natural pigment extracted and refined from the grains of Oryza sativa L. var. indica (black rice), a plant in the Poaceae (Gramineae) family. This pigment belongs to the anthocyanin class of natural colorants, with cyanidin-3-glucoside (chrysanthemin) as the main coloring component. The product appears as a red to purplish-red powder, easily soluble in water and aqueous ethanol solutions, and offers a clean, bright hue suitable for multiple industries.

Red Rice Red exhibits excellent coloring strength, high purity, and strong antioxidant properties. It is non-toxic, non-allergenic, and eco-friendly, making it a perfect alternative to synthetic colorants in foods, beverages, cosmetics, and nutraceuticals.

The pigment’s color tone and stability vary with pH:

• In acidic conditions, it shows a stable red to purplish-red color.

• In neutral environments, the color shifts to bluish tones.

• In alkaline solutions, it becomes greenish and unstable.

Because of its vivid and natural hue, Red Rice Red is widely used in acidic foods and beverages, such as fruit juices, jams, jellies, wines, yogurts, and confectionery products. Beyond its coloring properties, it also delivers functional health benefits thanks to its anthocyanin compounds, which are known for their antioxidant, anti-inflammatory, and anti-aging effects.

This pigment is extracted using aqueous or ethanol extraction technologies under controlled temperature and pH, preserving the integrity of anthocyanins and ensuring food-grade safety.
