This study examined the quality characteristics of cookies prepared with mulberry leaf powder (0, 1, 3, 5, and 7%) substituted for flour. The pH of the cookie dough decreased significantly in response to the addition of all levels of mulberry leaf powder. The spread factor of the cookies also increased significantly with increasing mulberry leaf powder content added to the cookies recipe. In addition, the Hunter's color L and a values decreased significantly with increasing mulberry leaf powder content, whereas the b value increased. According to hardness measurements, the substitution of 1~7% mulberry leaf powder resulted in increased hardness compared to the control. Moreover, the DPPH free radical scavenging activity of the cookies was increased significantly (p<0.05) with increasing levels of mulberry leaf powder. The sensory evaluation revealed cookies containing 3% to have the highest scores.

This study was performed to determine the optimum ratio of ingredients in the Sulgidduk with barley(Hordeum vulgare L.) sprout powder. A mathematical analytical tool was employed for optimization of the typical ingredients. The canonical form and trace plot showed the affect of each ingredient in the mixture against the final product. Mixture design showed 14 experimental points, including 4 replicates for three independent variables. The three independent variables selected for the experiment were: water($15{\sim}22%$), barley sprout powder($1{\sim}4%$), and sugar($12{\sim}19%$). The optimum responses variables such as color values(L, a, and b), instrumental texture parameters(hardness, gumminess, and chewiness), and sensory characteristics(appearance, color, smell, taste, softness, moistness, and overall acceptability) were evaluated. The Hunter colorimetric L- and a-values of the Sulgidduk decreased with an increasing amount of barley sprout powder. As more barley sprout powder was added, a higher b-value resulted. Textural hardness, gumminess, and chewiness were lowered by the addition of barley sprout powder. The optimum formulation obtained by both numerical and graphical methods showed similar results. The representative optimal ingredient ratio commonly obtained by both methods were: 18.2% water, 2.0% barley sprout powder, and 14.8% sugar.

Riceyeotgangjung (RYG) with added spirulina was prepared with citron juice for masking of odor. Oil temperature for puffing was found to be $220^{\circ}C$ for frying dry rice based upon the results of expansion rate and color. RYGs with added spirulina (1, 2, and 3%) were prepared under the above conditions, and their physicochemical and sensory properties were examined under storage at $60^{\circ}C$ for 15 days. Moisture content of RYG decreased proportionally with the spirulina content and storage time. The hardness levels of the freshly made RYGs with spirulina were higher than that of control. During storage, the hardness of the control gradually increased, but those of the RYGs with spirulina gradually decreased, although no significant differences existed between the spirulina containing RYGs. Lightness and redness values in the Hunter color system decreased according to the spirulina content and storage time. Yellowness value also increased with the spirulina content and storage time. Phycocyanin and total phenolic content increased with spirulina content, but decreased with the storage period. Sensory evaluation results showed that RYG with 2% added spirulina received the highest scores for color, taste, overall acceptability, and intention of purchase. As a result, the optimal addition amount of spirulina to RYG is recommended to be 2%.

This study was carried out to investigate the properties of mul-kimchi made with allium victorialis. Chemical and sensory characteristics were determined during fermentation at $4^{\circ}C$ for 4 weeks. The pH decreased with an increase in total acidity. Mul-kinchi showed salinity properties ranging within $1.0{\sim}1.5%$ during fermentation. Hunter's color L, a-values were gradually decreased, but b-value was increased. In the texture, hardness and strength decreased as the aging time increased. The numbers of total- and lactic bacteria cells rapidly increased up to the second week, and this slowly increased thereafter. Sensory evaluation of mul-kinchi was favored for appearance, flavor, taste, texture and overall acceptability during the second week. Sensory properties of well ripened odor and sour taste negatively correlated with physicochemical properties of pH and hardness. Sour odor and sour taste were positively correlated with acidity and total- and lactic acid bacteria.
