  • This study was conducted to investigate the effects of paprika juice on the quality characteristics of Jeung-Pyun (fermented and steamed rice cake). Jeung-Pyun was prepared with four different levels of orange paprika juice (0%, 10%, 25% and 50% replacement of water). The proximate composition analysis showed that moisture contents of Jeung-Pyun were 48.72∼49.36%, and crude protein, lipid and ash contents were 2.94∼3.13%,0.46∼0.63% and 0.60∼0.65%, respectively. The pH of Jeung-Pyun batters was decreased from 4.74∼4.83 to 4.27∼4.38 during 4 hours of fermentation at 35$^{\circ}C$. The maximum expanded volume was observed in control group, followed by 10% group, 25% group and 50% group and the volume expansion was decreased with the increased amount of paprika juice. The "L" value (lightness) was the highest in control group and decreased with paprika juice addition, while the "b" value (yellowness) was increased as the amount of paprika juice was increased. Rheology test showed that there were no significant differences in hardness an cohesiveness among four groups. Springiness and gumminess were the lowest in control group and increased with the increased amount of paprika juice. Results of sensory evaluation showed that there were no significant differences in scores of cell uniformity, sweetness, moistness and overall desirability between control and 10% group. Therefore. Jeung-Pyun prepared with 10% paprika juice was evaluated as the most acceptable one among test groups when compared to control.

  • This study was conducted to preserve the quality of Gangjung (Traditional Korean cookies) during storage with the addition of sorbitol in Gangjung dough. Sorbitol was added with different levels (0, 1.5, 3%) in the Gangjung dough and the Gangjung samples were stored for different periods (1, 16, and 31 days). Compared to the control group, the Gangjung samples with sorbitol groups had higher moisture content, expansion ratio, and ceil size. As the storage was extended, peroxide values, hardness, fracturability, chewiness and stickiness to teeth were increased, while cohesiveness, moistness, and degree of melting were decreased. From the PCA in the sensory analysis, Gangjung with addition of 3% sorbitol stored for 1, 16, and 31 days showed high levels in moistness, cohesiveness, degree of expansion, cell size, and degree of melting, whiie Gangjung in control group stored for 16 and 31 days showed high levels in fracturability, heated oil flavor, chewiness, and stickiness to teeth. The moisture content of Gangjung was significantly increased as the level of sorbitol was increased. The changes of physicochemical and sensory characteristics by storage were increased in control groups the most, 1.5% sorbitol groups the next, and 3% sorbitol groups the least. Therefore, the sorbitol added groups could be delayed in the quality deterioration during storage, especially in the texture, and could be increased in the preservation of Gangjung.

  • This study added black lentil ethanol extract to Yakgwa at ratios of 0%, 0.5%, 1.0%, and 2.0%, and its quality characteristics were compared to those of the synthetic antioxidant BHT added to Yakgwa. Yakgwa with black lentil extract had lower moisture content than Yakgwa with BHT (3.98%) but higher content than the control group (5.72%). Higher black lentil extract resulted in less moisture content (p<0.001) as well as a faster expansion rate and oil absorption rate (p<0.001). Scanning Electron Microscopy (SEM) showed that as black lentil extract content increased, pores merged and collapsed, whereas the number of pores decreased and pore size became larger. For chromaticity, all L, a, and b values of the group containing black lentil extract were higher compared to the control group and group with BHT (p<0.001). For texture, as amount of added black lentil extract increased, hardness (p<0.001) and gumminess (p<0.01) increased while cohesiveness (p<0.01) decreased compared to the control group. For sensory characteristics, Yakgwa with 1.0% black lentil extract showed the best preference for all items except for off-flavor. Thus, 1.0% black lentil added to Yakgwa was the best in terms of functionality including preference.
