Amylopectin Staling of Cooked Milled Rices and Properties of Amylopectin and Amylose.
Starches of waxy rices that showed varietal differences in hardness testing of cooked rice after amylopectin staling and high-amylose content (AC) rices differing in gel consistency (GC) and starch gelatinization temperature (GT) were studied to determine the factors related to varietal differences in amylopectin staling of cooked rice.
Isoamylase-debranched amylopectins of waxy rices differed in the ratio of weight-average degree of polymerization (DP(w)) fractions, but these fraction ratios were not simply related to differences in amylopectin staling of cooked rice.
