bilberry dry extract

Huacheng’s bilberry dry extract (Vaccinium myrtillus L.) is a fine, hygroscopic powder with typical color ranging from dark violet to deep purple. The fruit is harvested at peak ripeness in central Europe and processed within 48 hours to preserve anthocyanins. Ethanol-water extraction followed by mild concentration and spray drying yields a product with minimal thermal degradation. We offer standard grades from 5% to 25% anthocyanins by UV spectrophotometry, as well as HPLC-verified profiles for marketers who need precise delphinidin and cyanidin glucoside data. Carriers such as maltodextrin or anti-caking silica are added only when the customer requires improved flow or reduced clumping in capsule filling machines. Because we operate our own GMP, BRC, and HACCP-certified facility and manage a closed-loop supply chain from contracted non-GMO fields, we pass genuine cost advantages on to buyers. A typical batch comes with full heavy metal, residual solvent, and microbiology testing aligned with USP and EP monographs. Shelf life is confirmed at 24 months for material stored below 25 °C in sealed, light-resistant drums. We also offer custom granulation and organic certification upon request. For development teams, 100 g evaluation samples are dispatched free of charge, and our quality assurance group is available to discuss specifications before you commit to a purchase order.
