The physicochemical and sensory properties of barley Kochujang added with germinated barley powder were periodically examined during storage at 20 for 40 days. The pH of barley Kochujang added with germinated barley powder increased gradually according to the level of added germinated barley powder, whereas it decreased gradually during storage. On the other hand, acidity showed the opposite relationship with addition level. Salinity of the samples decreased gradually according to the amount of added germinated barley powder. Amino nitrogen content of barley Kochujang increased gradually according to the amount of added germinated barley powder, whereas it increased gradually during storage. L-, a-, and b-values of samples increased gradually according to the amount of added germinated barley powder, whereas they decreased gradually during storage. As a result of the sensory evaluation, barley Kochujang added with 5% germinated barley powder was found to be superior in taste, viscosity, and overall preference. Sensory evaluation revealed that addition of 5% germinated barley powder was optimum for improving Kochujang quality.

This study was conducted to investigate the effect of Curcuma longa L. powder (CLP) on the quality characteristics of a dumpling shell. Dumpling shell samples were prepared with wheat flour and different amounts of CLP were added to them, after which their instrumental characteristics and sensory evaluation were investigated. The gelatinization temperature of the CLP-wheat flours composite increased, whereas its initial viscosity at 95℃, viscosity at 95℃ after 15 min and maximum viscosity all fell with the increasing CLP content, as measured via amylography. As increasing amounts of CLP were added, the L value decreased, whereas the a and b values increased. With regard to the textural characteristics, the CLP additive became harder, more cohesive and adhesive, and less springy. The DPPH free radical scavenging activity increased significantly as the CLP content increased (p<0.05). Overall, the dumpling shells with 3% CLP were preferred over the other samples, as tested via sensory evaluation.

This study was conducted to promote the use of fish paste with shrimp powder as a food. The tested shrimp powder concentrations were 0, 3, 5, and 7%. The pH of the samples ranged from 6.80 to 6.95, and their moisture contents ranged from 70.15 to 70.75%. Their L values decreased as their concentrations increased, and their a and b values increased. The folding test for all the test samples showed AA, which indicates good flexibility. In the texture meter test, the hardness, cohesiveness, and springiness increased when the shrimp powder concentration increased. The gumminess and brittleness of the fish paste was reduced, however, with the addition of shrimp powder. In the sensory evaluation, the fish paste prepared with 5% shrimp powder were preferred most. These results suggest that shrimp powder can be applied to fish paste to achieve high quality and functionality.
