gelation concentration was ranged between 8 to 12 % in nonwaxy rice (Yellow-11, Chainat-1, and KDML-
105) whilst that of germinated flour from waxy rice was 14%. Gelation is an aggregation of denatured
molecules. Germination may break down the rice proteins and, thus caused more denature when heated and
aggregation than in the ungerminated rice flour. These results would be useful in food systems require thin
thickening and gelling agents.
