Contenido de acido cianhídrico en raíces y hojas de clones "amargos" de yuca (Manihot esculenta)

Abstract

Ten clons of bitter cassava, Manihot esculenta, were analyzed for their HCN content in roots and leaves. In general, the acid content in roots was larger than in leaves. The values of HCN found in the samples have a range of 0.112 to 1.327 mg/g d m for roots and range of 0.262 to 1.327 mg/g d m for leaves. It was found no correlation between the HCN content in roots and leaves. The time for the complete digestion of the cyanogenic glucoside linamarin is crucial for maximal HCN liberation, a fact that should be kept in mind when parts of this plant (roots and/or leave) are to be detoxified for direct animal consumption.
