Differential pulse polarography (DPP) with dropping mercury electrode (DME)
was used to determine quantitatively galacturonic acid (GA), methylated
polygalacturonic acid (met PGA), pectin (PC) and pectinase (PE) in 0.1 M NaClO4
as supporting electrolyte. Current peaks of GA, met PGA, PC and PE, at -1.55, -
1.50, -1.40 and -1.60 V vs SCE respectively, were found suitable for quantitative
determination in the concentration range considered. Enzymatic reaction between
PE and PC was followed and possibility to determine simultaneously of PC and PE
was proved.
