This study was carried out to develop character notes and to define the terminology for the evaluation of soybean curd using quantitative descriptive analysis. Panelists were selected according to their performance with ranking on basic tastes, flavor and texture properties related to soybean curd. After being trained, they identified the following attributes and defined the terminology: appearance(smoothness of the surface, amount of cracks, yellowness, grayness), flavor(sweet, salt and bitter tastes, cooked bean, raw bean, wet wheat flour, roasted bean, astringency), and textural properties(hardness, elasticity, inner moistness, coarseness, adhesiveness, and residuals). Reference samples for flavor attributes were also determined. Four types of commercial soybean curd were evaluated with the technique developed. Among soybean curd samples, there were significant differences in the intensity of all sensory attributes, confirming appropriateness of the evaluation methodology.

Fat and sugar reduced yellow layer cake system was developed with varied replacement level of 30%, 60%, and 90% for AD(amylodextrin) and 10%, 30%, and 50% for PD(polydextrose). Physicochemical and sensory characteristics were investigated and optimum replacement level was also decided using response surface methodology. Sample groups of PD10AD30 had significantly the lowest specific gravity and viscosity, indicating the stable batter system with high air incorporation. Sample groups with PD10AD90 showed the highest volume index and were not significantly different from those of the PD10AD30. Sensory results indicated that PD30AD30 were significantly the most springy and moist, and the least hard of all sample groups. Sample groups with PD10AD90 had the least adhesiveness value. To establish the optimum substitution level using RSM, the restriction level was set up as moistness over five point, hardness under five points, and adhesiveness under four points. The optimum substitution level was 20% for PD and 88% for AD.

This study examined the quality characteristics of Jeungpyun prepared with different additions of nano-filtered (NF) tofu whey concentrates. The initial pH values of the Jeungpyun batters ranged from 5.64 to 5.78, and decreased to 4.77-4.98 after 4 hours of fermentation at $35^{\circ}C$. The volume and specific volume values of the control Jeungpyun were lower than those of Jeungpyun samples prepared with 1%, 2%, and 3% NF powder. The color of the Jeungpyun became increasingly greenish-yellow as the NF powder level increased. Hardness and brittleness decreased with increasing NF powder content, while cohesiveness and springiness were not significantly different. Sensory evaluations revealed that as the level of NF powder increased, takju smell and sourness increased, but no significant differences were observed for sweetness and moistness between the control and NF powder groups. In terms of overall acceptability, the results revealed that Jeungpyun can be prepared with up to 1% NF powder in place of rice powder and be deemed as acceptable as a control Jeungpyun product.

In the fabrication of sponge cakes, wheat flour was substituted by Dioscorea Japonica flour at 3%, 6%, and 9% (C1, C2, and C3, respectively), and the sensory, physicochemical, texture properties, viable cell counts and chromaticity of the samples were investigated and compared with the control cake (C0). The addition of Dioscorea Japonica flour increased the density of the sponge cake, but decreased the size and moisture content of the cakes (C0〉C1〉C2〉C3). The pH value increased with increasing Dioscorea Japonica flour in the sponge cakes, and the microbial growth was remarkably suppressed by Dioscorea Japonica flour compared with the control. There was an increase in the chromaticity of the sponge cakes with increased Dioscorea Japonica flour in the cakes. Also, the hardness, gumminess, and chewiness were enhanced approximately two times higher than those of control by increasing Dioscorea Japonica flour. In the sensory evaluation, the addition of Dioscorea Japonica flour into sponge cakes showed a significant increment in the internal color, size/uniformity of the voids, and the sweetness, while the adhesiveness and moistness were the highest in the control. The overall preference was in the order C0〉C2〉C3〉Cl, and therefore, the substitution of 6% of wheat flour by Dioscorea Japonica was recommended in the fabrication of sponge cakes.

The purpose of this study was to investigate the effects of the addition of various amounts (0, 1, 3, 5%) of Mokdanpi(P. suffruticosa) powder on the shelf life and the physicochemical, sensory characteristics of rice cakes and noodles to examine the possibility of using Mokdanpi as a natural food preservative for food products. The decrease in the moisture content of rice cake and noodle samples during storage was much less in Mokdanpi-added groups than the control group. The color L value increased and a and b values decreased in the rice cake samples, and color L value, b value decreased and a value increased in the noodle samples during storage. The microbial growth was less in Mokdanpi-added groups than the control group. In sensory evaluation, there were no significant differences among the control and 1, 3%-added groups in terms of color, flavor, taste, moistness, cohesiveness and overall quality; however, 5%-added groups received significantly less score than others (p＜0.05). As the storage time increased, the sensory scores decreased significantly in the control and 1 %-added groups of both rice cakes and noodles (p＜0.05), but no changes were observed in 3, 5%-added samples. The results suggested that Mokdanpi is effective in increasing the shelf life and inhibiting the staling of rice cakes and noodles.
