Retrogradation tendencies of starch from local materials at two storage temperatures (10 and 30°C) were investigated. The kinetics of the crystallization process were studied using the Avrami equation. The values for the Avrami exponent and rate constant differ greatly at the two storage temperatures and for the various starches. The behavior of 50:50 (w/w) binary mixtures of starch on retrogradation was also investigated. The starches when combined were found not to behave independently of each other; rather, an interaction between the two starches combined was observed.
