Pineapple extract bromelain

When sourcing Bromelain, the most critical factor is enzymatic activity, usually measured in GDU/g (Gelatin Digesting Units) or MCU/g (Milk Curdling Units). Standard commercial grades typically range from 600 GDU/g to 2400 GDU/g. You must also verify the pH stability range (typically 4.5 to 8.5) and ensure the moisture content is below 5% to maintain enzyme stability during storage.

As a food additive or dietary supplement ingredient, Bromelain must meet strict safety standards. Ensure the supplier provides ISO 22000 or HACCP certifications for food safety management. For entry into the US market, FDA registration and GRAS (Generally Recognized as Safe) status are essential. For European markets, compliance with EFSA regulations and REACH may be required. Additionally, Halal and Kosher certifications are highly recommended to broaden market reach.

Bromelain is primarily extracted from the pineapple stem (Stem Bromelain) rather than the fruit, as the stem contains a higher concentration of the enzyme. Buyers should request a Certificate of Analysis (COA) for every batch to check for heavy metal limits (Lead <3ppm, Arsenic <1ppm) and microbiological purity, ensuring the absence of E. coli and Salmonella.

Bromelain is highly heat-sensitive and hygroscopic. It must be stored in a cool, dry place (ideally below 20°C) and away from direct sunlight. Professional suppliers should use double-layer PE bags inside fiber drums. For long-distance cross-border shipping, vacuum packaging or the inclusion of desiccant packs is vital to prevent activity loss due to moisture.

The primary risk in enzyme procurement is 'activity decay.' Always request a pre-shipment sample from the specific batch you will receive and have it tested by a third-party lab (like SGS or Eurofins). Use Made-in-China.com's Audit Reports to verify if the supplier has the specialized laboratory equipment necessary to test enzymatic activity in-house.

Bromelain prices fluctuate based on pineapple harvest seasons. To secure the best rates, consider long-term supply contracts or purchasing during peak harvest months. For bulk orders exceeding 500kg, aim for a 15-20% discount compared to sample pricing. Ensure the contract specifies that the lead time (usually 7-15 days) starts only after the quality of the pre-production sample is confirmed.

Since Bromelain is a biological enzyme, temperature-controlled shipping is preferred for high-activity grades. Ensure the supplier provides a Material Safety Data Sheet (MSDS) and a Non-Hazardous Chemical Certificate to avoid customs delays. For shipping to the US or Europe, clarify the Incoterms (FOB or CIF) and ensure the seller is experienced with customs clearance for botanical extracts.

Utilize Trade Assurance services provided by platforms like Made-in-China.com to protect your payment until the goods are delivered and inspected. Never wire full payments upfront to unverified accounts; instead, use a 30% deposit and 70% balance payment structure against the Bill of Lading (B/L) and a successful third-party quality report.
