  • This study was undertaken to investigate the effect of cereals on the physicochemical and sensory charac teristics of Noti. Noti is one of Korean traditional pan-fried glutinous cereal cakes. In this case, Noti was made from the steamed glutinous Indian millet flour. Acid value was not increased abruptly, TBA value was main tained, and reducing sugar content was increased as compared with the first day that glutinous Indian millet Noti was made during 90 day storage. Through sensory evaluation, color, flavor, moistness, and consistency (the inner part) were unfavorable according to the storage. The texture tended to increase depending upon the storage period. The hardness of glutinous Indian millet Noti by Instron measurement was slowly increased. Cohesiveness and elasticity were increased during storage.

  • This study investigated the effects of adding hard and soft wheat flour to Korean rice cakes(Karedduk) to retard retrogradation, by examining texture properties and descriptive sensory qualities after 2 and 24 hrs of storage at $5^{\circ}C$. The hard and soft wheat flour were combined with dry rice flour at levels of 0, 5, 10, and 20%. The texture properties, as analyzed by a Texture Analyzer, revealed that the springiness, cohesiveness, and adhesiveness of the rice cakes containing wheat flour were similar to those of the control, while chewiness, gumminess, and hardness were lower compared to the control. Also, in sensory analyses, hardness was significantly different in the rice cakes containing wheat flour compared to the control after 24 hrs of storage at $5^{\circ}C$. Overall, the instrumental texture properties were highly correlated with the sensory characteristics. These results suggest that adding hard and soft wheat flour to Korean rice cakes(Karedduk) is effective at retarding retrogradation.

  • Physical, textural and sensory properties of Seolgiddeok prepared with different amounts of broccoli(Brassica oleracea var. italica Plen.) powder were investigated during 3 days of storage. Moisture content decreased gradually during storage and was less in broccoli powder-amended samples. The color L value decreased significantly with increasing broccoli powder, whereas both redness and yellowness increased. Texture analyses revealed that hardness, chewiness, gumminess, adhesiveness and fracturability of Seolgiddeok tended to decrease in proportion to the amount of broccoli powder in the formula. Seolgiddeok gelatinization was investigated using amylographing. Break down and setback were low in broccoli powder Seolgiddeok. Sensory evaluations revealed that, Seolgiddeok prepared with broccoli powder was superior in flavor, chewiness, softness to unamended samples. Seolgiddeok prepared with 3% broccoli powder showed the highest overall acceptability score. Use of broccoli powder in Seolgiddeok preparation improves sensory characteristics and delays retrogradation.

  • The sensory quality and the baking property of blonds containing 10-50% of rice flour with wheat flour were analysed by QDA. As sensory characteristics, color, air cell size, air cell distribution, flavor, softness, chewiness and overall quality were evaluated. Bread could be made successfully even using up to 50% rice flour. The color, flavor, softness and chewiness were increased in rice-wheat bread especially using 10∼30% of rice flour, but in case of using 40∼50% of rice flour those characteristics were not significantly different from those of wheat bread. The size of air cell in 10∼30% rice-wheat bread was not significantly different but in 40∼50% rice-wheat bread it was increased. The distribution of air cell was more even in 10∼30% rice-wheat bread than in wheat bread, but not in 40∼50% rice-wheat bread. The overall quality of rice-wheat bread was shown to be better in 10∼30% rice-wheat bread than in wheat bread.

  • This study attempted to examine the effects on sensory characteristics, texture and color of steamed soybean rice cake in various levels of soybeans. Sensory evaluation was done by panels of 7 judges. Objective measurements were made by utilizing the Instron and Hunter Colormeter. The results were as follows; 1. The content of moisture, total ash, protein, fat and carbohydrate in rice were shown to be about 13.47%, 0.48%, 6.40%, 0.54% and 79.11%. Those of soybean were 10.95%, 4.54%, 30.67%, 20.36% and 33.48%. 2. The results of sensory evaluation revealed that rice cake containg 20% of soybean produced the best quality in most sensory characteristics. 3. By Instron measurement of various levels of soybean in steamed soybean rice cake, hardness and cohesiveness were not different. By color value of that, b value was tend to increase as the addition level of soybean.

  • The characteristics of sponge cakes containing sucrose or other sweeteners for diabetes mellitus patients were investigated through physical measurement and sensory evaluation. The results are as follows: The physical properties of cake batters and cakes with sweeteners were different from each other in viscosity, specific gravity, standing height, firmness, and springiness. from the result of sensory evaluation, it was shown that cakes containing sorbitol and fructose had high quality even though they were not as good as cake with sucrose. However, cakes with saccarine and stevioside showed much difference compared with cake with sucrose. The characteristics of sponge cake with combined sweeteners (sorbitol plus stevioside) were compairable to those of sucrose cake. There was little difference in specific gravity. The result of sensory evaluation indicated the combined use of both sweetenes could produce bette cakes than either stevioside or sorbitol. Practical utilization of this cake would be provided under the sensory evaluation on these cakes by diabetes mellitus patients.

  • This study was conducted to investigate the effect of Korean red pepper extracts on physiological and sensory characteristics. The Korean red pepper extracts were added to chocolate at weight percentages of 0, 2, 4, and 6%. The sensory characteristics made with various Korean red pepper concentrations of the additives were measured as follows: color values (L-value, redness, and yellowness), total phenol, total capsaicinoid, total carotenoid, and ABTS radical scavenging activity. In sensory evaluation, significant differences (p<0.05 and p<0.01) were shown in taste, spiciness, and overall acceptability depending on the addition of pepper extracts. However, there were no significant differences in the properties of aroma and bitterness for chocolate.

  • This study was conducted in order to investigate the quality characteristics of Salku Pyun which was made by using mungbean, potato, sweet potato and corn starches. The pH of salku juice was 3.45 to 3.50 and the brix of that was 7.0%. The water content and water activity of salku pyun with potato starch was highest. The result of sensory evaluation showed that appearance, flavor, overall quality were highest in the Salku Pyun made with potato starch while texture, taste were highest in the Salku Pyun made with mungbean starch. Mechanical properties of salku pyun with mungbean starch was significantly higher in adhesiveness, hardness, chewiness. Texture of sensory evaluation were positively correlated with springiness, hardness, and chewiness of mechanical measurement. The factors which affect the overall quality on sensory evaluation were texture quality, taste quality, hardness, color and springiness.

  • The saccharification and sensory characteristics of Sikhe, Korean traditional beverage of saccharified rice, made from thirteen glutinous rice varieties and one of non-glutinous rice named I1pum were examined. During saccharification, Shinsunchalbyeo, Whasunchalbyeo, Yukdononhrimna 1 and Hangangchalbyeo showed the highest sweetness determined by refractometer. Yukdononhrimna 1 was good for the morphology and texture of cooked rice kernel during saccharification. There was interrelationship between contents of released reducing sugar and sweetness determined by refractometer during preparation of Sikhe. The overall acceptability determined by sensory evaluation of Sikhe made from Yukdonongrimna 1, was slightly higher than that of Sikhe made from Ilpum, the non-glutionous rice variety. Yukdononhrimna 1 was considered to the most suitable varieties of Sikhe.
