Black Rice Extract

Black Rice Extract from Shaanxi Shengyudan is a fine powder derived from the bran of black rice, standardized to contain 1% to 25% anthocyanidins by weight, with concentration ratios of 4:1 to 200:1. The extract appears as violet red to dark violet powder, passing through an 80-mesh sieve. Testing follows UV spectrophotometry for anthocyanidin quantification, ensuring batch consistency. This product is not a whole grain but a concentrated phytochemical extract intended for nutraceutical and cosmetic applications.

The anthocyanin profile is dominated by cyanidin-3-glucoside (C3G) at 25%, a common marker for black rice extracts in the industry. The moisture content is not specified but typical for powdered botanicals, under 8%. The powder is free-flowing and stable under dry, cool storage. Standard industry grades for such extracts range from 5% to 20% anthocyanidins; this supplier offers a broader range to accommodate varying formulation needs, including lower concentrations for colorants and higher ones for antioxidant claims.

Buyers include manufacturers of dietary supplements, functional beverages, and natural colorants for cosmetics. The minimum order quantity is 1 kg, with sample availability for qualification. Packaging is typically in food-grade polyethylene bags inside kraft drums, suitable for dry transport. Trade terms are FOB China port, with lead time under 10 working days after payment confirmation. Buyers should confirm the exact anthocyanidin concentration required for their application before placing bulk orders.
