ObjectiveThe objective of this study was to quantify the amount of hydrogen cyanide in cassava leaves that were treated before drying and the concentration of phytic acid in a multimixture submitted to wet cooking. MethodsThe multimixture produced by the Pastoral da Criança of the city of Pelotas (RS) consisting of wheat flour (30%), rice flour (30%), corn flour (15%), wheat (10%), egg shell powder (5%), cassava leaves (5%) and pumpkin or sunflower seeds (5%) was used. The supplier was advised on how to process the cassava leaves before drying them. ResultsThe hydrogen cyanide and phytic acid contents of the feeding supplement are 85mg.kg-1 and 35.90mg.100-1 respectively. ConclusionChanging the way the cassava leaves were dried was efficient to reduce the amount of cyanogenic glucosides. The cooking process of the ingredients was enough to reduce the phytic acid content in the multimixture to the levels recommended by the legislation. Significant statistical differences were not observed between these samples and those treated with moist heat.
