VALIDATION OF AN ANALYTICAL METHODOLOGY TO QUANTIFY CYANOGENIC GLUCOSIDES IN COMMERCIAL CASSAVA PRODUCTS
A spectrophotometric method for determining cyanogenic glucosides (CGs) was validated in accordance with IUPAC and ICH requirements for new methods. The method demonstrates good linearity in the range of 0.1-0.88 μgg-1 hydrocyanic acid (HCN). The accuracy of the method ranges between 95.2% and 96.4%...

| Résumé: | A spectrophotometric method for determining cyanogenic glucosides (CGs) was validated in accordance with IUPAC and ICH requirements for new methods. The method demonstrates good linearity in the range of 0.1-0.88 μgg-1 hydrocyanic acid (HCN). The accuracy of the method ranges between 95.2% and 96.4%. The precision of the method, reflected as the relative standard deviation of the replicates, is lower than 12%. The method was compared with the most used method to detect CGs in cassava roots, the one established by Essers et al. Both methods were applied to quantify CGs in commercial cassava products. The new method is a useful and reliable tool for monitoring levels of CGs in cassava commercial products. |
