Cassava (Manihot esculenta Crantz) is widely used in human and animal nutrition and also as a raw material for various industrialised products, of which the most important are the cassava flour, cassava starch and sour cassava starch (Avancini et al., 2007). Subjecting
cassava starch to a natural fermentation process, varying the conditions such as processing time and location, or to the action of microbial enzymes, promotes the formation of organic
acids, yielding the fermented starch, commonly known as sour cassava starch.
