Import Black Soybean Peel Extract — Buy in Bulk from Supplier in China

Black Soybean Peel Extract is a botanical concentrate derived from the seed coat (testa) of Glycine max (L.) Merr., the cultivated soybean. This particular material from Xi'an Longze Biotechnology Co., Ltd is standardised for anthocyanidin content, with the supplier listing a concentration range of 1-15% as measured by ultraviolet spectrophotometry (UV). The extract captures the pigment-rich outer layer of black soybean varieties, which accumulates cyanidin-3-glucoside and related flavonoid compounds during seed maturation. Xi'an Longze Biotechnology Co., Ltd operates from Shaanxi province, a region with established fermentation and phytochemical extraction infrastructure.

The raw material for this extract consists of black-hulled soybean cultivars, distinct from yellow or green commercial varieties in their elevated polyphenolic content. Anthocyanidin standardisation at 1-15% UV indicates a broad product tier, suitable for formulators requiring either economy-grade colouring agents or higher-purity antioxidant fractions. Typical extraction solvents for this class of product include aqueous ethanol or water, followed by spray-drying to yield a hygroscopic powder. The dark purple-to-black colour of the finished extract correlates directly with anthocyanin concentration and pH stability. Buyers should request the specific analytical method (HPLC versus UV) and standard reference (cyanidin-3-glucoside chloride or equivalent) to reconcile this 1-15% figure with their own quality systems.

Primary applications span dietary supplements (capsules, tablets, softgels), functional beverage colourants, and cosmetic formulations where natural origin claims support marketing positioning. Nutraceutical manufacturers value black soybean peel for its ORAC contribution and potential vascular health associations, though regulatory positioning varies by destination market. Cosmetic formulators employ it in anti-ageing serums and natural colour cosmetics, exploiting both the chromophore and antioxidant functionality. Food and beverage applications remain jurisdiction-dependent, with some markets permitting anthocyanin colourants under E163 (grape skin extract) analogies while others require novel food assessments. Import buyers should verify with Xi'an Longze Biotechnology Co., Ltd whether the specific grade offered aligns with their target application (food, cosmetic, or reagent), as purification levels and residual solvent profiles differ significantly across these tiers.

Xi'an Longze Biotechnology Co., Ltd is located in Xi'an, Shaanxi province, China (postal code 710065), a city with substantial concentration of botanical extract manufacturers serving domestic and export markets. The supplier holds a harbour trust tier, the base verification level on this platform. The response rate displays as 0.00% with zero average response hours, indicating either a new listing, dormant account, or unconfigured inquiry management. No information is provided about facility certifications such as ISO 9001, ISO 22000, HACCP, or GMP compliance, nor about organic, kosher, or halal credentials. Buyers should request current GMP or food safety certification documentation directly.

The company profile does not state year of establishment, registered capital, employee count, annual turnover, or named domestic or international clients. No details are given about in-house analytical capabilities (HPLC, GC-MS, ICP-MS) or whether quality control is subcontracted. The source description references ISO and SGS, but these are generic claims from platform marketing copy, not verified supplier statements. Shaanxi province does host several established phytochemical clusters, yet proximity to raw material sources (soybean growing regions) is not confirmed for this specific supplier. Direct due diligence, including facility audit or third-party inspection, is advisable before committing to volume orders.
