This study was carried out to investigate the quality characteristics of yellow layer cake mulberry powder. After making yellow layer cake with mulberry powder, water activity, crumb texture, crumb color, and sensory tests were investigated. After 1 day of storage, Aw of control with weak flour did not show any significant difference, whereas those with 1, 3. 5% mulberry powder showed a significant decrease in Aw. During storage, the Aw values of yellow layer cakes containing mulberry powder were consistent. Hardness, springiness, cohesiveness, and gumminess of the yellow layer cakes containing mulberry powder all decreased compared to those of control. Hardness, springiness, cohesiveness, and gumminess all increased with storage time. Further a higher percentage of mulberry powder was associated with a lower L value, but higher a value. b values were lower in the 1% and 3% mulberry powders, but 5% showed a slightly higher b value. An increase in storage time was associated with decreased L and b values and increased a value. The micrographs of yellow layer cakes with mulberry powder showed a slightly coarser porosity than that of controls. The results of the sensory test showed that the over-all acceptability of 1% mulberry powder cake was the best.

This study investigated yakpyun processing using jujube powder. The yakpyun was prepared with rice, jujube powder, makkolli, sugar, and salt. The yakpyun is made with various amounts (0, 2, 4, 6, 8%) of jujube powder. The effect of adding jujube powder on the quality characteristics of yakpyun were examined through SEM, mechanical tests, and sensory evaluation. The moisture contents of yakpyun were significantly reduced with increasing amounts of jujube powder. As the content of jujube powder increased, the lightness (L) decreased while redness (a) and yellowness (b) increased significantly (p<0.05). In texture profile analysis, hardness increased with increasing jujube powder content from initial production to three days of storage. In the structure of yakpyun examined through SEM, when more jujube powder was added, rougher surfaces were found more often (bigger holes between granules). The results of the sensory evaluation showed that the highest scores for overall acceptability were highest scores for yakpyun containing 6% level jujube powder. In conclusion, an addition of 6% jujube powder was optimal.

This study was carried out to investigate the quality characteristics of Baiksulgis made of imported rice(Thai and Chinese rice, harvested in 1998) and domestic rice(Chuchung byeo, harvested in 1998 and 1997). Moisture content, color value, yields of reducing sugar by $\beta$-amylase reaction, texture and sensory properties of Baiksulgis were measured. Moisture contents of rice flour and Baiksulgi made of Korean rice harvested in 1997 were highest and those of Thai rice were lowest among the samples. This tends were also seen during storage. Lightness and redness of Baiksulgi made of Thai rice were lowest and yellowness of Baiksulgis made of Korean rice harvested in 1997 and Chinese rice were higher than those made of other rices. Yield of reducing sugar by $\beta$-amylase reaction was highest in Baiksulgi made of Korean rice harvested in 1998 and lowest in Baiksulgi made of Thai rice. And the value decreased less than half of initial value after 24 hour storage. Adhesiveness of Baiksulgi made of Thai rice was zero and cohesiveness, chewiness and gumminess of that were very low. This results showed that Baiksulgi made of Thai rice was lack of chewy texture and this trend was more apparent as the storage time increased. In sensory tests, Baiksulgi made of Chinese rice had most yellowish color and that made of imported rice such as Chinese and Thai rice had more coarse texture than that made of domestic rices. off odor was lowest in Baiksulgi made or Korean rice harvested in 1997 and sweet taste was lowest in that made or Thai rice. Hardness adhesiveness, moistness and chewiness of Baiksulgi made of domestic rices were much higher than those made of impoted rices, and these results showed that Baiksulgi made of domestic rices had acceptable texture. Baiksulgi made of Thai rice showed the lowest acceptability due to lack of above textural characteristics and it was needed to add the material to modify the texture of that.

The effects of substituting whey protein concentrate (WPC) powder for rice flour in the preparation of seolgiddeok were determined by objective and subjective tests. Milk whey is drained from milk curd as a by-product of the cheese manufactureing process. Whey protein is known as a good nutritional source and is a functional material for many processed foods. WPC contains more than 80% whey protein. The moisture content decreased gradually during storage and the decrease in moisture was less in the control than in the WPC powder substituted groups. The color lightness (L) decreased significantly as the amount of WPC powder increased, wherease redness (a) and yellowness (b) both increased. Texture analyses revealed that the hardness, chewiness, gumminess and adhesiveness of seolgiddeok tended to increase in proportion to the amount of WPC powder in the formula. Seolgiddeok gelatinization was investigated by amylographing. Initial pasting temperature, peak viscosity, hot pasting viscosity and breakdown were low in seolgiddeok prepared with WPC powder substituted for rice flour. Setback had the lowest value in the control. Sensory evaluations revealed that, seolgiddeok prepared with 3% WPC powder had the highest overall acceptability score. These results indicated that WPC seolgiddeok with 3% WPC powder has the best quality.

The aim of this study was to use purple sweet potato powder to develop a recipe for a nutritional cookie with an optimal composition of ingredients and texture, in order to acquire strong preference responses by all age groups in sensory tests. Wheat flour was partially substituted with purple sweet potato powder to reduce the wheat flour content of the cookies. Measurements were made and analyzed according to the Response Surface Methodology technique, which showed 16 experimental points including 3 replicates for the purple sweet potato powder, sugar, and butter. The compositional and functional properties of the sample were measured, and the values obtained were applied to a mathematical model. A canonical form and perturbation plot showed the influence of each ingredient on the final product mixture. The results of sensory evaluations showed very significant values for flavor (P<0.0071), texture (P<0.0306), taste (P<0.0190), and overall quality (P<0.0142). Instrumental analysis showed significant values for hardness (P<0.0027), yellowness (P<0.0061) and spread ratio (P<0.0001). The optimal compositional ratios were determined to be 21.75 g for the purple sweet potato powder, 37.05 g for the sugar, and 60.59 g for the butter.
