Glutinous rice cake(Chalduk) was made by varying the hours of soaking time of glutinous rice in the water(0, 4, 8, 12, 24 hours). After storage for various periods, the sensory and physical characteristics and the degree of gelatinization were examined in order to determine the effect of glutinous rice soaking period on the quality of Chalduk. The results of the study are summarized as follows. In the sensory test, 8-hour water soaking produced the significantly highest score for salty taste, while 0-hour water soaking had the lowest score. Four-hour water soaking had the significantly highest score for the degree of chewiness. Eight-hour water soaking had the significantly highest score for overall desirability. For the moisture content of Chalduk covered with bean flour, 8-hour water soaking produced the highest moisture content but the difference was not significant. For the degree of gelatinization, 8-hour water soaking had the highest maltose content, which confirmed the suitability of 8-hour water soaking glutinous rice. Eight-hour water soaking had the lowest hardness. With increasing storage period, the hardness sharply increased. Elasticity was higher for the long-period immersed samples than for the non-immersed samples. In conclusion, an 8-hour soaking time for glutinous rice in water was proposed to maximize the Chalduk quality.
