In order to produce the high quality rehydrated acorn Mook(Korean tradition gel flood) that enhance acceptability, the optimum condition was investigated for the rehydration process of dried Monk as salt concentration(0, 1, 2%), temperature(20, 70, 80, 90$^{\circ}C$) and time. The estimation of moisture gain, rehydration efficiency was analyzed statistically. The surface color md seniory evaluation were undertaken to evaluate the rehydrated Mook quality The optimum rehydration time was decided to 15 minutes and it takes 3 minutes for the cooling tilde. The moisture gain increased as the rehydration temperature increase. And the moisture gain and moisture gain rate were higher at 1% salt solution than other concentration. As the rehydration efficiency, surface color and sensory properties of rehydrated Mook, 1% salt treatment was superior.

The present study replaced Atarigoma with Korea &Chinese sesame values a nd analyzed basic data on various mook to develop Korea's food culture. Contents of oleic acid and linolenic acid in sesame seed were 42.31% and 48.18%, respectively, with a total moisture content of 89.5%. As storage temperature increased, moisture content increased. Cohesiveness and springiness decreased gradually at $4^{\circ}C$ and increased at $20^{\circ}C$, whereas gumminess and chewiness increased at $4^{\circ}C$ and gradually decreased at $20^{\circ}C$. Overall acceptability scores of Japanese and Korean arrowroot starch sesame mook were 7.20 and 7.10, respectively. Korea and Japanese Sesame can be substituted for sweet potato starch, potato starch, and arrowroot starch.

This study was carried out to make the new products of color moot as a functional food by variation of the color and flavor through addition of gamgyul, Daccus Carota Var. Sativa, Vitis vinifera, soy sauce, and Pimpinella brachycarpa N., respectively. For all the products, the color was observed by Colorimeter and the sensory evaluation was performed to evaluate their effectiveness and usefulness. The A$_w$ (water activity) test of color mooks has performed to examine their water activity individually. The A$_w$ of color moot was higher than that of the white one. The characters of texture of color mook as a function of the amount of the color and the flavor added were measured by a texture analyzer (XT-RA, Texturometer). By the TPA test, the rainbow and orange color mook examined were high in the springiness.

The objectives of this study are to establish efficient pretreatment concentration and rehydration process for the production of the high quality of freeze-dried Mook, a traditional gel food in Korea, as an instant food. Effect of immersion in sucrose solution as pretreatment before freeze-drying on the rehydration efficiency and quality characteristics was studied. The rehydration efficiency of non-treated Mook was the highest. The rehydration efficiency increased as the concentration of sucrose increased. The texture of rehydrated Mook treated in sucrose solution was decreased with increase in rehydration temperature. The Mook treated at 60% sucrose solution was somewhat similar to the market selling Mook in the quality and the treatment prevented color and texture degradation.

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.

The principal objective of this study was to evaluate the quality characteristics of black ginseng mook prepared with different 5 levels(0, 1, 2, 3, and 4%) of black ginseng extract. We conducted the pH, sugar content, Hunter's color values, the mechanical characteristics and a sensory evaluation analysis of black ginseng mook. The more black ginseng extract was increased, the sugar contents of black ginseng mook were significantly increased. We noted that the luminance and Hunter's b values of black ginseng mook samples were decreased the more black ginseng extract was increased, but in Hunter's a values was reverse. With regard to the mechanical properties of the black ginseng mook samples, the more black ginseng extract was increased, the score of hardness, gumminess and chewiness were significantly decreased, but adhesiveness was increased. In color, taste, flavor and overall quality, the score of 3% black ginseng mook was significantly higher than those of the all.

This study was performed to investigate the physiological functionality of jerusalem artichokes and to define its antioxidant potential. The study also evaluated mook prepared with jerusalem artichokes powder as a new functional food for ameliorating Diabetes Mellitus. Regarding the chromaticity of mook prepared with jerusalem artichoke, lightness decreased as the amount of jerusalem artichoke increased (p < 0.05), while the redness and yellowness values increased significantly (p < 0.05). Regarding the mechanical properties, hardness, springiness, chewiness, gumminess, and cohesiveness decreased significantly as the amount of jerusalem artichoke increased (p < 0.05). The total polyphenol and flavonoid contents of JA30 were 7.36 mg TAE/g and 2.15 mg RE/g, respectively, which were higher than those of the control group(3.50 mg TAE/g and 0.76 mg RE/g, respectively). The DPPH and ABTS scavenging abilities ($IC_{50}$) for JA30 were 4.40 and 5.70 mg/mL, respectively, indicating a higher radical scavenging ability than the control group (7.59 and 7.24 mg/mL, respectively). The ${\alpha}-glucosidase$ inhibitory effect ($IC_{50}$) of JA30 and the control group was 18.91 and 24.01 mg/mL, respectively. Based on the above-described results, mook containing jerusalem artichoke powder is expected to ameliorate diabetes with antioxidant activity, ${\alpha}-glucosidase$ inhibitory effect, and sensory factor. Also, it is believed that this functional material has the potential to improve health.

Some physicochemical properties and molecular structure of cow pea, mung bean and acorn starches(mook-forming starches) and red bean, wheat and sweat potato starches(mook-unforming starches) were investigated. Amylose contents of cow pea, mung bean and acorn starch were higher than the others. Cow pea starch was similiar to mung bean starch in gelatinization characteristics by Brabender amylogram but cold viscosity of red bean starch and peak viscosity of sweet potato starch were especially high. Whereas viscosity of wheat starch was low in whole temperature range. Amylose molecules of larger molecular size$(above\;5{\times}10^5\;molecular\;weight)$ of three mook-forming starches were more than shoes of red bean and wheat starch. Chain distribution ratios$(DP\;35{\sim}55\;to\;DP\;10{\sim}20)$ of cow pea, mung bean and acorn amylopectin were higher than thoes of red bean, sweet potato and wheat amylopectin.

This study was to explain the properties of acorn sediments and characteristics in the texture of acorn mooks due to the differences in preparing conditions of acorn sediments. The hardness of mook increased at 4$^{\circ}C$ during storage. The increase rate of acorn mook's hardness after storage for 24 hrs at 4$^{\circ}C$ were higher than those of others. X-ray diffraction of the retrograded acorn mooks was little different during storage at 4$^{\circ}C$. The syneresis of acorn mook was decreased with increasing the soaking treatment. The syneresis (%) of nontreated sample (0-0) was larger than those of the others.
