Tapioca starch

Tapioca starch suppliers and sourcing guide

Tapioca starch is the starch extracted from the roots of the cassava plant (Manihot esculenta), grown mainly in Thailand, Vietnam, Indonesia and Brazil. Roots are washed, grated and wet-milled, the starch is separated from fiber and juice, washed, then dewatered and dried to a fine white powder. Brands buy native tapioca starch as a clean-tasting thickener and binder, and in supplements as a filler or capsule excipient.

Forms and grades of tapioca starch

Suppliers sell different products under the same name. Specify the one you need.

Native tapioca starch
Unmodified, dried starch; thickens when cooked and gives a clear, slightly stretchy gel.
Pregelatinized tapioca starch
Cooked and dried so it thickens in cold water, used in instant mixes.
Modified tapioca starch
Chemically or physically modified grades for freeze-thaw, acid or heat stability, labeled as modified starch.
Organic
Starch made from certified organic cassava, with the organic certificate tied to the lot.

What to check on the COA

Compare each result with your own specification when the lot arrives.

Identity and starch content: Microscopy or iodine identity and starch content on a dry basis; some buyers also ask for amylose content.
Moisture: Loss on drying, typically up to about 13% to 14% for native tapioca starch.
Viscosity and whiteness: Brabender or RVA pasting viscosity and whiteness, which vary with root variety and processing.
Residual cyanide and sulfite: Cyanide (from the cassava root) and sulfur dioxide (sometimes used in processing) against the supplier specification.
Ash, pH and pulp/specks: Ash, pH and visible specks or pulp, which indicate how well fiber was removed.
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.

Storage, lots and expiry

Storage and shelf life

Keep in sealed multiwall bags or bulk bags in a dry, cool warehouse, off the floor and away from odors and pests. Starch takes up moisture in humid air, which can allow mold growth, so limit time open. Shelf life is set by the supplier specification; aged stock is retested for moisture and micro.

Lots and expiry dates

Viscosity, whiteness and moisture vary with harvest and mill, and native starch from different origins can thicken differently at the same dose. Record origin, viscosity and moisture per lot, and run a cook test when switching suppliers.
