liquid elderberry extract

The liquid elderberry extract from Huacheng Biotech comes out of a production flow built on direct raw material access and integrated extraction workshops. The company operates its own elderberry supply nodes in central China, which helps lock in harvest timing and ripeness without depending on third-party traders. Berries are cleaned, dried, and then macerated in a food-grade ethanol-water solvent under controlled temperature. After filtration, the liquid is concentrated under vacuum to hit a target ratio – commonly 5:1 or higher – and standardized to an anthocyanin endpoint of at least 3%, measured by a pH-differential UV-Vis method. The final product is a viscous, dark-purple liquid with a characteristic tart-berry odor, soluble in water and alcohol. Typical specifications include: density 1.05–1.15 g/mL, pH 3.5–4.5, ethanol content < 0.5% (if alcohol-removed), and microbial limits meeting USP <2021> guidelines. Shelf life extends to 24 months when stored below 25°C in sealed drums, with potassium sorbate added as a preservative in standard batches. The extract fits into gummies, shots, syrups, and hard capsules after adsorption. Huacheng’s documentation package covers COA, residual solvent analysis, and heavy-metal test reports. The facility holds HACCP, GMP, and BRC certifications, and products are registered with FDA for U.S. exports. Buyers working on cost-sensitive retail lines can pull from this stream without paying for extra marketing claims.
