pure blueberry extract

Hunan Huacheng Biotech supplies pure blueberry extract as a fine purple powder, standardized for anthocyanins—the compounds behind the fruit's deep color and studied antioxidant properties. Our standard offering starts at 5% anthocyanins (UV), with higher concentrations available up to 25%. The product is water-soluble at room temperature, making it straightforward to incorporate into dry mixes, capsules, or liquids. We use ethanol/water extraction without harsh solvents; residual ethanol is removed during drying. Bulk density typically falls between 0.4 and 0.6 g/mL, and particle size passes 80 mesh unless otherwise specified. All batches come with a certificate of analysis listing anthocyanin content, heavy metals (Pb < 2 ppm, As < 1 ppm), and microbial limits (TPC < 1,000 CFU/g). Storage requires a cool, dry place away from light, with a 24-month shelf life in original packaging. Pricing is tiered by volume: 25 kg drums suit trial runs, while pallet orders bring per-kilo costs down noticeably. We also offer private labeling with your brand and spec sheet if needed. Because we manage the supply chain from blueberry sourcing in China's northeastern provinces to final extraction, lead times stay around 15 working days for standard orders.
