Origin: indigenous Amazonian peoples (pre-colonial to present) — Amazon basin
See full technique reference →The process relies on lactic acid bacteria (e.g., Lactobacillus spp.) to convert fish-derived carbohydrates into lactic acid, while proteolytic microbes break down proteins into peptides, ammonia, and volatile sulfur compounds. The resulting acidification (pH 4.5–5.5) preserves the fish and imparts a characteristic pungent flavor.
