Tighter windows on any single parameter can be worked to where a buyer's process requires it. A certificate of analysis accompanies every shipment; extended panels — anthocyanin, pesticide residue, heavy metals, microbiology — are arranged through an international laboratory on request. Steam sterilization and additional cleaning passes are available where microbiological limits require them.
