QUANTITATIVE-ANALYSIS OF LINAMARIN IN CASSAVA USING A CASSAVA BETA-GLUCOSIDASE ELECTRODE

A simple protocol was developed for the quantitative analysis of linam arin in cassava roots using a cassava beta-glucosidase (linamarase) el ectrode. A steady state value could be obtained within 15-20 min and t he limit of detection was 0.1 mm linamarin. The linamarin content of 1 8 cassava varieties determined by this procedure ranged from 24 to 395 mg per 100 g fr. wt. root. These values were comparable to those obta ined using a spectrophotometric method. The enzyme electrode method is reliable and simple to perform. Furthermore, it does not require the use of hazardous chemicals like pyridine which is needed by the spectr ophotometric procedure.
