A new rapid method for the determination of honey diastase activity using direct 
potentiometric principles has been proposed. A platinum redox sensor has been 
used to quantify the amount of free triiodide released from a starch triiodide 
complex after starch hydrolysis by honey diastase. The method was tested on 
honey samples with varying diastase activities. The first 5 min of data for each 
sample were used for linear regression analysis in order to calculate diastase 
activity. The new method was compared with classical Schade and commercial 
Phadebas procedures. The results showed good correlations with both methods and 
offered a simple method for unit conversion to DN units for diastase activity, 
making the method suitable for routine analysis.
