THE EFFECT of SELECTED SALTS ON the MICROWAVE HEATING of STARCH SOLUTIONS

This research explores the effects of selected salts on the microwave heating profile of a 5% (w/w) starch solution containing salt. the salts used were NaCl, CaCl2, FeCl3, Na4P2O7, or Na5P3O10 at a concentration of 1% (w/w). the temperature of the starch solution was taken every 10 s for 90 s, and the heating curves have been plotted to show the effects of different salts on the heating of the starch solutions. There was a significant difference in the heating profile of samples containing salts versus those with without salt. However, there was no significant effect of type of salt used in the starch solution.
