This study examined the effects of added amounts of lotus leaf powder on the physical and sensory properties of Jook. As the level of lotus leaf powder in samples increased, L-values and a-values decreased and b-values increased. In addition, the Jook had higher viscosity and lower spreadability values as the amount of lotus leaf powder increased. Sensory characteristics such as color intensity, viscosity, astringency, and nutty taste increased significantly with the addition of lotus leaf powder. And the results of the consumer acceptability test showed that the Jook containing $2%{\sim}3%$ lotus leaf powder had the highest score. In conclusion, to enhance the quality of Jook, a 2% addition of lotus leaf powder would be the most beneficial.

This study was conducted to investigate the physical, textural and sensory properties of sponge cake prepared with different amounts of radish leaf powder. The specific gravity and viscosity of cake batter and cooking loss of cake increased with an increasing amount of radish leaf powder, whereas specific loaf volume and moisture content of cake decreased. Lightness, redness and yellowness of crust and crumb decreased with increasing radish leaf powder content. Measurements using a texture analyzer showed that hardness, chewiness, gumminess, adhesiveness and fracturability of sponge cake tended to increase in proportion to the amount of radish leaf powder in the formula. In the sensory evaluation, sponge cake prepared with 5% radish leaf powder was similar to the control in terms of moistness, softness, chewiness and springiness. These results suggest that adding 5% radish leaf powder is the best substitution ratio for sponge cake.

This study examined the effects of added amounts of shrimp powder on the physical and sensory properties of Jook for elderly foodservice operation. According to the amylograph data, the composite shrimp flour-wheat flour samples increased the gelatinization temperature, with increasing shrimp-flour content; moreover, initial viscosity at $95^{\circ}C$, viscosity at $95^{\circ}C$ after 15 minutes, and maximum viscosity were reduced. As the level of shrimp powder in samples increased, L-values decreased, and a-values and b-values increased. In addition, the Jook had higher viscosity and lower spreadability values as the amount of shrimp powder increased. Sensory characteristics, such as nutty taste, color, viscosity, and overall preference increased significantly with the addition of shrimp powder. In conclusion, to enhance the quality of Jook, a 3% addition of shrimp powder would be the most beneficial.

The influence of cabbage powder on sensory acceptance and physical functions of Jeungpyun, were assessed. As fermentation continued, pH dropped and evolved carbon dioxide significantly increased. Moisture content of cabbage powder-amended Jeungpyun ranged from 51.1~55.5%, and were lower than those of control samples. Jeungpyun prepared with 8~10% cabbage powder displayed significantly lower specific volumes. As the level of cabbage powder increased, the L-value was reduced, while the a- and b-values increased. Hardness was not significantly different among the control, 2%, 4% and 6% samples. Chewiness tended to increased in proportion to the level of cabbage powder. Sensory scores were lowest for Jeungpyun prepared with 8~10% cabbage powder. The results indicate that addition of 4~6% cabbage powder to Jeungpyun produces the optimal product.

Rice dumpling shells were prepared with different levels of hydrocolloids, such as hydroxypropyl methyl cellulose (HPMC), and potato starch. After steaming, the physical, sensory, and cooking properties of the shells were measured. Increasing the amount of potato starch decreased the pasting temperature and increased the peak viscosity. With the addition of hydrocolloids, water absorption and cooking loss for the rice dumpling shells decreased significantly. For the textural properties, the rice dumpling shells with hydrocolloids showed lower hardness and higher springiness than the control, and especially, 10% potato starch and 3% HPMC addition (P10H3) improved the texture of the rice dumpling shells the most. The sensory results seemed to be affected more by the addition of potato starch than HPMC, and over 15% addition of potato starch significantly decreased the quality of the rice dumpling shells. By addition of adequate amount of hydrocolloids (3% HPMC and 10% potato starch), the sensory quality of rice dumpling shells can be effectively improved.

Kongjaban (a Korean-style seasoned black soybean) prepared under various conditions such as different soaking temperatures and time, cooking rate, and amounts of sugar and soy sauce was investigated with respect to its physical and sensory qualities. Soaking soybeans in water at $20^{\circ}C$ and $60^{\circ}C$ prior to heating decreased the hardness, degree of browning and saltiness of kongjaban, regardless of soaking temperature. As the cooking time after addition of sugar and soy sauce increased, the degree of browning, saltiness and hardness of kongjaban increased markedly. The amount of sugar and soy sauce did not make a distinct difference in its physical properties whereas its hardness increased slightly with increasing sugar amount. According to the sensory evaluation, the color, hardness and saltiness of kongjaban significantly increased with increasing cooking time. Color, hardness and sweetness increased as the amount of sugar increased whereas the amount of soy sauce did not affect the sensory characteristics except for saltiness.

The objective of this study was to determine the optimum mixing ratio of Opuntia humifusa powder and sugar in the preparation of muffin. The optimal sensory composite recipe was determined by following the central composites for muffin with different levels of Opuntia humifusa powder (A) and sugar (B). The analysis was performed using the response surface methodology, and the sensory evaluation was performed with the data. Ten experimental recipes, including two with reference points in the composition, were selected. The compositional and functional properties were measured, and the physical and sensory values were applied to the mathematical models. Perturbation plots showed the effects of each ingredient on the final product. Measurements showed significant values in lightness (p<0.05), sweetness (p<0.05), hardness (p<0.05), gumminess (p<0.05) and cohesiveness (p<0.01). The sensory measurements showed significant values in color (p<0.05), flavor (p<0.05), appearance (p<0.05), softness (p<0.05) and overall quality (p<0.05). Based on the numerical and graphical methods, the optimal formulation was determined to be 6.10 g of Opuntia humifusa powder and 82.61 g of sugar.

The effects of barley bran substitution on the quality of sugar-snap cookie and muffin were investigated using physical tests and sensory evaluation. Barley bran contained 29.04% starch, 16.23% protein, and 8.57% lipid. They were formulated by substituting the flour with the barley bran of 0, 10, 20, and 30%. Increasing levels of barley bran substitution reduced cookie spread, lightness, top grain scores and other sensory qualities. Cookies with 10% barley bran substitution, however, were not significantly different from the control cookies in sensory characteristics, and cookies with 20% barley scored well above the minimum acceptance level of 5 on a 9-point scale. Although the barley bran decreased muffin volume and had a deleterious effect on crumb grain, muffins with 10% bran had acceptable sensory properties. The physical and sensory results indicated that barley bran could be added to cookie and muffin at replacement levels up to 20% without a large adverse effect on cookie and muffin quality.

The health of modern people is threatened by bad eating habits. In order to provide healthy desserts to people, we conducted a study on adding plum concentrate, which is effective for fatigue recovery, insomnia, and prevention of constipation, to scones. In order to examine the utility of scones made by adding plum concentrate, the following experiment was conducted. It was prepared by adding 0g, 3g, 5g, and 7g of plum concentrate to the scone dough, respectively. As a result of the test, the sensory characteristic value was the highest in the experimental group to which 5 g of plum concentrate was added (4.77). There was a significant difference in that the average value tended to increase as the concentration of the plum concentrate increased. As for fragrance, the experimental group with the addition of 5 g of plum concentrate showed the highest sensory characteristic value of 3.62, but there was no significant difference. The experimental group to which 3 g of plum concentrate was added showed higher preference than the control group in most items such as color, flavor, sweetness, and overall preference. This study suggests that the production of scones with plum concentrate has a high potential for commercial use.
