Prebiotics

When evaluating prebiotic ingredients, focus on purity levels (typically >90%), solubility, and pH stability. Common types include Fructooligosaccharides (FOS), Galactooligosaccharides (GOS), and Inulin. Ensure the degree of polymerization (DP) matches your specific application, as this affects fermentation rates in the gut. For powdered forms, check the mesh size to ensure uniform blending in your final product.

As a food or supplement ingredient, prebiotics must meet stringent safety standards. Prioritize suppliers with HACCP, ISO 22000, or FSSC 22000 food safety management certifications. For specific markets, ensure the product is FDA GRAS (Generally Recognized as Safe) for the US, or has EFSA Novel Food authorization for the EU. Additionally, Halal and Kosher certifications are essential for expanding global market reach.

Request a Certificate of Analysis (COA) for every batch, specifically looking at heavy metal limits (Lead, Arsenic, Mercury) and microbiological counts (E. coli, Salmonella, Yeast & Mold). To verify efficacy, ask for clinical study data or in vitro fermentation reports that demonstrate the ingredient's ability to selectively stimulate beneficial bacteria like Bifidobacteria.

Prebiotics are often hygroscopic, meaning they absorb moisture from the air. Ensure the supplier uses multi-layer moisture-proof packaging (e.g., PE bags inside fiber drums). The standard shelf life is usually 24 months when stored in a cool, dry place (below 25°C) away from direct sunlight. Verify that the supplier provides stability testing data under accelerated conditions.

Utilize third-party inspection services (such as SGS or Intertek) to conduct pre-shipment inspections and lab testing. Always use Trade Assurance or secure payment terms through reputable platforms like Made-in-China.com to ensure your funds are protected until the quality is verified.

Focus on tiered pricing based on volume; for orders exceeding 5 tons, you can typically negotiate a 10-15% discount. Discuss customized mesh sizes or concentrations without significant price hikes. Request free samples (50g-200g) for initial lab testing before committing to a full container load.

Ensure all packaging is clearly labeled with HS Code 294000 (for sugars) or 382499 (for chemical products) depending on the specific type. Provide a detailed Material Safety Data Sheet (MSDS) to the freight forwarder. For sea freight, use reefer containers if shipping through high-temperature tropical zones to prevent clumping or degradation.

Conduct a factory audit (either virtual or physical) to confirm the supplier is a manufacturer and not a middleman. Check their business license and export permits. Conduct all communications and transactions through Made-in-China.com to maintain a documented paper trail for dispute resolution.
