Current batch and quality verification
The current batch was manufactured in October 2026 and expires in September 2028. Key results: Activity: 2,480 GDU/g; Loss on drying: 3.5%; Residue on ignition: 2.5%; Identification: Complies. The full results table is shown below, and the COA is issued on Herbuno letterhead.
Sourcing and qualification
- Bromelain activity is unit-specific. GDU (gelatin digestion units) values are not directly interchangeable with FIP, PU or MCU figures, so formulators should convert only with a validated method rather than a fixed factor.
- The current batch exceeds specification by about 3% (2,480 vs 2,400 GDU/g). Enzyme activity declines with heat and moisture, so plan label claims with an overage and keep material below 25 °C in sealed packs.
- Enzyme dust is a recognised respiratory sensitiser. Use dust controls and the respiratory protection described in the SDS when blending or encapsulating.
Frequently asked questions
How is the 2,400 GDU/g activity measured?
By gelatin digestion: one GDU is the amount of enzyme that liberates 1 mg of amino nitrogen from a standard gelatin solution in 20 minutes under assay conditions. The method of analysis is available on request through the form on this page.
Does the batch contain a carrier or diluent?
The full percentage composition is available in writing on request through the form on this page.
Can I get a sample?
Yes. A 100 g sample from the offered batch can be arranged against a qualified enquiry.
Can I order more than one pack?
Yes. Order any number of 25 kg packs at checkout at the listed price. For a sample, extra documents or a freight estimate on a large volume, use the request form on this page.
