- Dextrose equivalent
- DE by Lane-Eynon titration or an equivalent reducing-sugar method, reported against the grade range.
- Moisture
- Loss on drying against the supplier maximum; higher moisture causes caking.
- Bulk density
- Loose and tapped bulk density, especially for low-density oil-absorbing grades.
- Residual cyanide and SO2
- Some buyers ask for cyanide and sulfur dioxide results because of the cassava source.
- Heavy metals
- Lead, arsenic, cadmium and mercury by ICP-MS against the supplier specification or the buyer's own limits.
- Microbiology
- Total plate count, yeast and mold, coliforms or E. coli, and Salmonella. Starches are dry and low in water activity, but buyers using them uncooked in powders or tablets check micro on every lot.
