Garlic extract allicin

The most critical factor is the active ingredient content, typically measured as Allicin (0.5% to 5%) or Alliin (up to 25%). Buyers must distinguish between Garlic Oil (steam distilled) and Garlic Powder Extract (solvent extraction). Ensure the product has a high bioavailability and check for deodorized options if the application is for consumer-facing supplements where odor control is essential.

For food and supplement grades, suppliers must provide ISO 22000 or HACCP certifications. If exporting to the US, FDA registration and GMP (Good Manufacturing Practice) compliance are vital. For European markets, ensure the extract meets REACH and EFSA standards. Additionally, Kosher and Halal certifications are highly recommended to expand market reach.

Always request a Certificate of Analysis (COA) for every batch. Professional buyers should look for HPLC (High-Performance Liquid Chromatography) testing results to confirm Allicin potency. It is also necessary to test for heavy metals (Lead, Arsenic, Mercury) and pesticide residues, ensuring they fall below the limits set by the USP (United States Pharmacopeia) or EP (European Pharmacopoeia).

Allicin is highly heat-sensitive and unstable. It should be stored in cool, dry conditions (below 25°C) away from direct sunlight. Packaging must be vacuum-sealed or use nitrogen-flushed aluminum foil bags or high-density polyethylene (HDPE) drums to prevent oxidation and moisture absorption, which can degrade the active compounds.

The primary risk is potency degradation during long-transit shipping. Another risk is adulteration with synthetic fillers to lower costs. To mitigate this, use third-party inspection services (like SGS or Intertek) to perform random sampling at the factory before the final balance payment is made.

Focus on tiered pricing based on Allicin concentration rather than just total weight. Request a sample for lab testing before committing to a bulk order. For long-term partnerships, negotiate flexible MOQs and ask for Gold Member or Audited Supplier status verification on Made-in-China.com to ensure supplier reliability.

Garlic extract is often classified under HS Code 130219. Ensure the supplier provides a Material Safety Data Sheet (MSDS) and a Phytosanitary Certificate to avoid customs delays. For large volumes, Sea Freight (FCL/LCL) is cost-effective, but for high-potency samples, Air Express is preferred to minimize time-sensitive degradation.
