PRACTICAL WALKTHROUGH · PARAMETERS · COMMON MISTAKES
Fermented cassava acidifies and preserves fish, then the sealed product is heat‑sterilized at 121 °C for safety.
Origin: Yanomami and Kayapo peoples (pre‑colonial to present) — Amazon Basin, Brazil
See full technique reference →During fermentation, cassava starch is metabolized by lactic acid bacteria producing lactic acid, ethanol and acetic acid, lowering the pH to 3.5–4.0 and inhibiting mesophilic spoilage microbes. Subsequent canning at 121 °C for 15–20 min achieves a 6‑log reduction of Clostridium botulinum spores, ensuring long‑term storage.
Primary Reaction
Lactic acid fermentation of cassava starch to lactic acid, ethanol and acetic acid
