Gelatinization characteristics of 111 glutinous rice varieties were evaluated by Rapid Visco Analyzer. Gelatinization viscosity of glutinous rice tested varied with ecotypes or varietal groups: indica, japonica, and Tongil type. Indica rice showed the highest average value of initial pasting temperature. The average values for peak, hot, and cool viscosities were highest in Tongil-type rice, and lowest in japonica rice. Japonica showed the lowest breakdown and consistency, but the highest setback value. Indica was lower in alkali digestion value (ADV), and shorter in gel length after gelatinization thanjaponica and Tongil-type. Glutinous rices tested could be divided into six groups by cluster analysis based on their gelatinization characteristics. Group I-A was mostly early maturing japonica varieties while I-B was mostly indica and Tongil-type rices. Groups II-A and II-B were consisted of very early maturingjaponica, and III-A and III-B included medium or medium late maturingjaponica varieties. Group III-A showed the lowest average values of peak, hot, cool, and consistency viscosities, and also in breakdown and setback ratios. Group I-B revealed the highest values in peak, hot, cool, breakdown, and consistency viscosities. ADV was low in groups I-A, I-B, and II-B, and gel consistency was not different among the six varietal groups. Principal component analysis using seven traits related with gelatinization produced four effective components, and the first and second components were highly correlated with all the gelatinization characters evaluated.

A standard samples of Jangduck were soybean paste : glutinous rice flour : ground beef : green onion : garlic : toasted white sesame=100 : 10 or 20 or 30 : 30 : 10 : 5 : 2 (％) and measured acceptability by 15 days. Jangduck estimated for texture characteristics through acceptability. The acceptability of Jangduck was by both objective and subjective methods. Objective measures were made utilizing the Rheometer and Hunter colorimeter. Sensory evaluated was done by a panel of 10 judges. The data analysis revealed following as for estimate of texture changes during storage by Rheometer, the hardness tended to increase as the addition level of glutinous rice flour and beef till 30 days. Hardness decreased slightly after 30 days of storage. Elasticity and cohesiveness tended to increase as the addition level of glutinous rice flour till 15 days and decreased slightly from 16 days to 60 days later By color value of Jangduck, Lightness tended to increase as the addition level of beef during storage periods. Redness tended to increased as addition level of beef before storage and decreased 15 days later. Yellowness increasde than others from days later to 15 days later as the addition level of glutinous rice flour. The result of sensory evaluation revealed that Cl [soybean paste : glutinous rice flour : ground beef : green onion : garlic : toasted white sesame=100 : 30 : 30 : 10 : 5 : 2(％)] produced the best quality in most sensory characteristics during storage.

This study was designed to determine blood glucose responses to some cereals produced in Korea. The levels of blood glucose were measured over 2 hours after feeding healthy vounteers with 50g carbohydrate portions. The glycemic index(GI)k and glycemic index-rice(GI-rice) of a food has been defined as : GI=mean of (blood glucose response area of test food/ blood glucose response area of glucose taken by the same indicidual) $\times$100 and GI-rice=mean of (blood glucose response area of test food/blood glucose response area of rice taken by the same individual) $\times$100. The area under the curve is taken to be the area above the fasting value calculated geometrically from blood glucose increments. The GI of barely to glucose as the standard(57$\pm$7) was significantly (p<0.05) lower than those of other cereals whereas the GI of glutinous rice (110$\pm$8) was significantly (p<0.05) higher than other those of cereals. The GI values to rice as the standard were 63 $\pm$6 for barley, 79$\pm$5 for buckwheat, 85$\pm$6 for foxtail millet, 90$\pm$12 for unpolished rice, 100$\pm$0 for rice, 102$\pm$7 for glutinous rice, 106 $\pm$6 for unpolished glutinous rice, 115$\pm$13 for glutinous millet, 116$\pm$13 fro job's tear, and 122 $\pm$ 4 glutinous sorghum. The mean GI-rice was identical to the mean of the adjusted GI values, with a correlation coefficient of r=0.964(p<0.0001). This finding suggests that white rice could be used as standard food for the determination of GI.

In this study, the physicochemical and sensory properties of glutinous rice kochujang added with germinated barley powder were periodically examined during storage at $20^{\circ}C$ for 40 days. The pH level of glutinous rice kochujang added with germinated barley powder increased gradually with a higher amount of germinated barley powder, whereas it gradually decreased during storage. On the other hand, acidity showed the opposite pattern. The salinity of samples decreased gradually with a higher amount of germinated barley powder. The L-, a and b-values of samples increased gradually with a higher amount of germinated barley powder, whereas they decreased gradually during storage. Amino nitrogen content of glutinouse rice kochujang increased gradually with a higher amount of germinated barley powder, whereas they increased gradually during storage. In the sensory evaluation, glutinous rice kochujang added with 5~10% germinated barley powder was superior in color, texture and overall preference. Therefore, addition of 5~10% germinated barley powder was optimum for improving kochujang quality.
