| Abstract Tucupi is a product obtained from the fermentation and cooking of cassava root wastewater which is widely used in the popular cuisine of the North region of Brazil. This study employed an experimental design to select tucupi processing (fermentation and cooking times) as a function of residual cyanidric acid content and assess the stability of the product obtained. Although the design did not generate a predictive mathematical model, the trend plots and physicochemical and sensory tests indicated 24 h of fermentation and 40 min of cooking as process parameters. The tucupi prepared had pH 3.71, titratable acidity of 0.7 g lactic acid/100 mL, 93.91% moisture, 0.5% ashes, 0.52% proteins, 0.24% lipids, 4.83% carbohydrates, total and free cyanide of... |
