The physical properties and sensory characteristics of acorn starch gels (Dotori Mook), which were gamma-irradiated up to 3 kGy, were evaluated during storage at $4^{\circ}C$. Even at the dose of 2 kGy, the gamma irradiation decreased total bacteria in the Dotori Mook during 5 days of storage, to lower than the detection limit $(10^2CFU/g)$. The hardness of the control sample increased according to the days of storage, while the gamma irradiated samples had decreased hardness according to the irradiation dose. The sample irradiated at 3 kGy maintained the same hardness as the control at day 0 of storage. Irradiation did not affect the Hunter color values. No significant differences were observed in off-odor, color, springiness, and overall acceptability (p<0.05) at the irradiation dose of 2 kGy. It can be concluded that the irradiation of Dotori Mook, up to 2 kGy, does not affect the quality of the Mook during storage, with regard to texture and sensory characteristics. Moreover, the irradiated Mook was superior in maintaining hardness and had prolonged shelf-life time by sanitation.

Arrowroot Mook was prepared as a trial to develop new food items from natural resources, and its rheological properties were measured. 1. The starting point of gelatinization of 7% arrowroot starch solution was $67.5^{\circ}C$ as measured by amylograph. The viscosity of arrowroot starch reached the maximum 375 B.U. at $95^{\circ}C$ and decreased to 315 B.U. while holding at $95^{\circ}C$ for 15 min. When the temperature dropped to $50^{\circ}C$, the viscosity increased again to 530 B.U. 2. The gelatinization enthalpy of arrowroot starch was 15.603 J/g. 3. For the color, there were significant differences in b value for the arrowroot Mook made of arrowroot starch and in L value for the Mook made by the addition of arrowroot juice. 4. In descriptive analysis, $S_3$(14% arrowstarch) was most favored in color, and $S_1$(10% arrowstarch)was most favored in transparency, brittleness, fineness, and shininess. There were no significant differences in hardness, adhesiveness, and astringency. 5. On the contrary to mechanical measurement, there were no significant differences in hardness of samples as the addition of arrowroot juice increased, although there appeared a tendency to be softer in descriptive analysis. 6. The Mook prepared with 12% arrowroot starch was most favored by sensory evaluation. In case of adding arrowroot juice, the Mook containing 3% of arrowroot juice was most favored. Overall, arrowroot Mook showed a potential as a new food item.

This study was to examine the characteristics in the texture of acorn Mooks (acorn starch jelly) with different conditions to prepare acorn starch. By texture profile analysis, hardness and chewiness with 50% deformation were increased with increasing soaking days. Hardness of acorn Mook, measured by texture analyzer, showed significantly difference between the samples, and was closely related to the content of non-starchy substances and their intrinsic viscosity. The observation of microstructure through a scanning electron microscope (SEM) showed that acorn Mook showed finer and more fibrous structure than control(0-0), sample without soaking of acorn and sediments. Sensory characteristics of acorn Mook were affected by soaking treatment. The result of acceptance test on acorn Mooks indicated that the color and hardness increased with the increase of soaking days of acorn nuts and soaking times of sediments. There was a little difference between the samples in astringency taste. Their overall acceptability also increased except for 4-2 sample (i.e., soaking of acorn, 4 days; soaking of sediments, 2 times) and 4-3 sample (i.e., soaking of acorn nuts, 4 days; soaking of sediments, 3 times). As the results, the color, light brown, and the taste, a little astringency with consistency, were important factors of acorn Mook.
