Abstract
DSC was used to investigate the thermal mechanism of acorn and corn starch with or without saccharides on gelation and retrogradation. When the samples were starch-saccharide-water system (s-s-w), from measuring of gelation enthalpy and temperatures of initial gelation, peak and conclusion(T$\_$0/, T$\_$p/, T$\_$c/), those of s-s-w system were higher than those of stank-water system (s-w). The retrogradation enthalpy of acorn starch and corn starch was straightly increasing by DSC measurement as storage times. This increase meant slowly becoming recrygtallization of amylopectin. In retrogyadation process, the starch-saccharide-water system's enthalpy was also increased. After 7 days went, the value of the enthalpy was steady. Saccharides were retarding retrogrodation because of stopping the recrystallization of amylopectin. Especially in using fructose and maltose, the retrogradation effect of maltose was well. These elements took effect the number of juntion zone, one of equatorial OH and dynamic hydration number. As these three elements were increasing, a starch-Rel-system was stabilizing.
