The principal objective of this study was to assess the effects of maesil extract on yellow layer cake made with medium and cake flour. After making yellow layer cakes with maesil extract, water activity, hardness, Max G, springiness and crumb color were evaluated. During storage, the Aw of the yellow layer cakes prepared with maesil extract did not retain its consistency. The hardness, Max. G. and springiness of the yellow layer cakes prepared with maesil extract were all lower than that of the controls. With regard to the color of the yellow layer cakes, the L values were reduced, but the a and b values were increased with the addition of maesil extract. The micrographs of the yellow layer cakes prepared with maesil extract evidenced slightly higher porosity than was observed in the controls. This meant that the cake batter prepared with maesil extract could be used to create yellow layer cake with good volume and good quality.

The purpose of this study was to investigate the effects of Curcuma aromatica powder on the functional and sensory characteristics of Mandupi. Various Mandupi samples were prepared with wheat flour along with addition of various amounts of Curcuma aromatica powder, after which instrumental characteristics and sensory evaluations were investigated. According to the amylograph data, the composite Curcuma aromatica powder-wheat flour samples showed increased gelatinization temperatures with increasing Curcuma aromatica powder content, whereas initial viscosity at $95^{\circ}C$, viscosity at $95^{\circ}C$ after 15 minutes, and maximum viscosity were reduced. In terms of Hunter's color values, L value decreased while a and b values increased with increasing Curcuma aromatica powder content. Besides cooked weight, cooked volume and turbidity of Mandupi increased as the addition level of Curcuma aromatica powder increased. In terms of textural characteristics, addition of Curcuma aromatica powder increased springiness, chewiness, and brittleness, whereas springiness and adhesiveness decreased. Based on sensory evaluations, the overall preference of Mandupi with 3% added Curcuma aromatica powder was higher than that of control.

This study was carried out to investigate the acceptable ratio of Sulgidduk with added soybean curd residue powder. The moisture content of Sulgidduk with added soybean curd residue powder (0${\sim}$ 10%) ranged from 40.54 ${\sim}$41.38%, and there were no significant differences between the addition of soybean curd residue powder and control. There were also no significant differences in swelling power and pore ratio from control to the addition of 4% soybean curd residue powder. However, these decreased with increasing addition of soybean curd residue powder of more than 6%. The L (lightness) value decreased with increasing addition of soybean curd residue powder, but the a (redness) and b (yellowness) values increased significantly. As the amount of soybean curd residue powder increased, the hardness, cohesiveness, springiness and gumminess decreased, and, the decrease was especially significant with addition of more than 6%. With increases in the storage period, the hardness, springiness and gumminess increased, while cohesiveness decreased for all additions of soybean curd residue powder. In sensory evaluations, Sulgidduk with the addition of 4% soybean curd residue powder was the most preferred with regard to overall quality. These results indicated that the Sulgidduk with 2% and 4% added soybean curd residue powder exhibited the best quality.

This study was conducted to investigate the quality characteristics of soybean curd prepared with Opuntia ficus-indica fruit, freeze-dried Opuntia ficus-indica fruit powder, or heat-dried Opuntia ficus-indica fruit powder, without addition of a coagulant. The yield rates of the soybean curd were slightly decreased for the three curds containing Opuntia ficus-indica fruit; this was accompanied by a significant decrease in pH. Furthermore, the hardness and springiness of soybean curds coagulated with added freeze-dried Opuntia ficus-indica fruit powder or heat-dried Opuntia ficus-indica fruit powder were higher than the hardness and springiness of the coagulated controls. However, the cohesiveness and brittleness of two soybean curds were lower than for the controls, while the gumminess of the four soybean curds containing control fruit was the same. In terms of overall acceptability, the preferred soybean curd was the curd containing freeze-dried Opuntia ficus-indica fruit powder.

This study investigated the quality characteristics of tofu(soybean curd) samples prepared with differing amounts of commercial chungkukjang powder(0, 1, 2, 3, 4%). According to the results the 3% chungkukjang tofu 3%(C3) had the highest yield, and the tofus containing chungkukjang powder had higher pH and acidity levels than the control. Turbidity increased and moisture content decreased with increasing chungkukjang powder concentration. And pH, acidity, and turbidity were negatively correlated with moisture content. In terms of color, the L value decreased, and a and b values increased with increasing chungkukjang concentration. For texture, the 1% chungkukjang tofu(C1) had higher hardness, springiness, and cohesiveness values than the other samples. C1 also had the highest overall acceptability score. Finally, sensory properties of taste, texture, and overall quality were positively correlated with the mechanical properties of moisture content, hardness, springiness, cohesiveness, chewiness, and brittleness.

The objective of this study was to determine the characteristics of noodle dough made with biji powder (2, 4, 6 and 8%). Increase in the amount of biji powder significantly increases the water-binding capacity and decreases lightness (L) (p<0.05). The changes of redness (a), yellowness (b) and size of pore were insignificant. In the case of raw noodle, hardness, springiness, gumminess and chewiness of raw noodle significantly increased with increasing concentrations of the biji powder (p<0.05). Hardness of cooked noodle increased according with increase in concentration of biji (p<0.05). Springiness was increased up to 4% of biji concentration and slightly decreased at higher concentrations (p<0.05). Adhesiveness and cohesiveness of cooked noodle decreased according with increase in concentration of biji (p<0.05). The was no significant changes in the gumminess and chewiness. Taken together, addition of 4.0% biji powder to noodle dough may improve the preference of noodles.

This study examined the measurement conditions of the texture profile analysis (TPA) experiments that are typically used to measure the physical properties of sausage. As the measurement conditions (compression ratio and cross-head speed) were changed, the significant differences between the values of textural parameters (hardness, adhesiveness, springiness, cohesiveness, chewiness) of samples changed. Furthermore, among the measurement conditions, there was more variation in the significant difference between the value of samples due to a change in the compression ratio than due to a change in the cross-head speed. The highest variation in significant difference was observed between the values of cohesiveness of samples due to changes in measurement conditions, whereas the lowest variation in significant difference was observed between the values of springiness of samples due to change in measurement conditions. Therefore, it is desirable to provide a clear basis for setting specific measurement conditions for TPA test, since significant differences in the values of textural parameters of samples were caused by differences in cross-head speed or compression ratio, not by a difference in samples, when analyzing the cohesiveness of sausage, especially.

This study evaluated the quality and sensory characteristics of sulgidduk added with yam powder (5~20%) during 4 days storage. The moisture content of samples initially decreased as the yam powder content increased, but subsequently increased during storage. The pH values also increased during storage, although there was no significant difference. L values decreased and both a and b values increased as yam powder content increased. The decreased L values during storage were not significantly different from control group. The hardness of samples decreased with increasing yam powder content, while hardness of control group markedly increased during storage. Cohesiveness increased as yam powder content increased, and tended to decrease during the storage. Springiness also initially increased as yam powder content increased. No change was apparent during storage in control group or samples added with up to 10% yam powder, while springiness was decreased insignificantly in samples with over 10% yam powder. Lightness, yam odor and savory taste of sulgidduk tended to increase as yam powder content increased, while chewiness decreased. The savory odor was the highest in sulgidduk added with 10% yam powder. Sulgidduk added with 10% yam powder was the most preferred in appearance, taste, texture and overall preference.
