Curcumin powder extracts
Curcumin powder extracts from Naturalin Bio Resources Co.,Ltd contain 90% curcuminoids by weight, as confirmed by HPLC analysis, with curcumin, demethoxycurcumin, and bisdemethoxycurcumin in a ratio of approximately 77:17:6. The product is derived from the dried rhizomes of Curcuma longa Linn, processed through solvent extraction and spray drying to preserve bioactive compounds. No fillers, flow agents, or synthetic additives are added during manufacturing.
The powder is a bright yellow-orange fine particulate with a particle size distribution typical of pharmaceutical-grade extracts, passing through an 80-mesh sieve. It has a moisture content below 5%, consistent with standard requirements for stable nutraceutical powders. The extraction method uses food-grade ethanol and water, avoiding hexane or acetone, aligning with industry norms for clean-label supplements.
This extract is primarily purchased by manufacturers of dietary supplements, functional foods, and plant-based beverages seeking standardized curcumin content for efficacy. Buyers commonly use it in capsules, tablets, and ready-to-mix powders. Bulk packaging is in 25 kg HDPE drums with inner food-grade polyethylene liners. Trade terms are FOB Changsha Port, with lead times of 15 to 20 days after order confirmation.

Sourcing Curcumin powder extracts from Naturalin Bio Resources Co.,Ltd - China Import Guide
Before ordering, verify the HPLC certificate of analysis for curcuminoid content and individual compound ratios. Confirm that the moisture content was measured by Karl Fischer titration, not loss on drying, and request residual solvent data to ensure no hexane or acetone contamination. Check that the supplier provides batch-specific test results, not generic ones, as purity varies significantly between production runs.
Confirm the Incoterms as FOB Changsha Port, and clarify whether the supplier handles export documentation. Lead time is typically 15 to 20 days but may extend during Chinese holidays. Payment is usually by T/T, with 30% deposit and 70% against shipping documents. Ask for packaging details including liner material certification and drum specifications to ensure compliance with your country’s import regulations.
Conduct pre-shipment inspection for color consistency, absence of clumping, and proper sealing of drums. Request a Certificate of Analysis with microbial limits, heavy metals, and solvent residues. Ensure the product is labeled with batch number, expiry date, and storage conditions. Retain a sample from each shipment for third-party lab testing, as quality degradation can occur if stored above 25°C or in high humidity.
