The purpose of this study was to investigate the quality characteristics of Gamgyul-Injeulmi containing different ratios of Citrus mandarin powder(0, 3, 6, 9 and 12%). The moisture content of the control group was 45.37%. As the ratio of Citrus mandarin powder increased, moisture content decreased. The water holding capacity of glutinous rice flour with Citrus mandarin powder decreased gradually in proportion to the amount of Citrus mandarin powder added. An analysis of Hunter's color values for Gamgyul-Injeulmi indicate that the addition of Citrus mandarin powder leads to lower L value and higher a and b value compared to the control. Textural analysis of Gamgyul-Injeulmi showed that the hardness, cohesiveness, gumminess and chewiness increased as Citrus mandarin powder was added, whereas adhesiveness and springiness decreased. According to the sensory evaluation of Gamgyul-Injeulmi, as the ratio of Citrus mandarin powder was increased, the flavor, sweetness and hardness all increased. Gamgyul-Injeulmi with 6% Citrus mandarin powder was rated as the best in terms of color and for overall preference in the sensory evaluation.

This study was conducted to find an efficient use for mulberry fruit powder (MFP). MFP was added to salad dressing products at concentrations of 0.25, 0.5, 0.75, 1%, and pH, total acidity, viscosity, color, and emulsion stability were measured and sensory evaluation was conducted. There were no significant differences among salad dressing samples regarding pH, total acidity and moisture content. Salad dressing made with 0.5% MFP showed significantly higher viscosity during storage and made the most stable emulsion. For color, the control sample had the highest L and b values, and these values decreased significantly as the amount of MFP in the sample increased. The control salad dressing had the lowest a value of -3.26, and this value increased significantly as the amount of MFP in the sample increased. Sensory evaluation of salad dressing was performed by a trained consumer panel. The flavor intensity increased as the amount of MFP increased in the salad dressing samples. Sweetness was rated significantly higher as the amount of MFP increased in the samples. The control sample had the lowest sourness and off-flavor, but there was no significant difference compared to the samples containing MFP.

This research was studied to optimize the recipe of rice pound cake with two concentrations of Euonymus alatus and grape seed oil, using central composite design (CCD). The mixing condition of rice pound cake was optimized by subjecting it to sensory evaluation and mechanical and physicochemical analysis, using response surface methodology (RSM). The results of the mechanical and physicochemical analysis showed significant values for color (lightness, redness, yellowness), texture (hardness, springiness, chewiness, gumminess, cohesiveness), loss rate, volume, specific volume, sweetness, saltiness, moisture content and pH (p<0.05). The results of the sensory evaluation showed significant values for color, flavor, taste, softness, appearance and overall quality (p<0.05). As a result, the optimized compounding ratio was found to be 4.28 g of Euonymus alatus and 33.18 g of grape seed oil.

The cheese cakes of three family restaurants (A, B, and q were compared for water activity, Brix, free sugar contents, color difference, viscosity, and sensory evaluation. The carbohydrate contents of cheese cake made in B is higher than the others. However, the products in C have the highest values for the crude protein contents. In viscosity, the products in C have the lowest values in cutting strength and compression strength. In order to measure the quality of cheese cake for different family restaurants, 83 undergraduate students were selected. It is found that they like the products in A better than those in Band C for aroma, sweetness, and taste. The results suggest that the taste is the most important factor for quality, and the aroma is the secondary effective factor.

This study was intended to investigate the optimal soaking time of glutinous rice for making jujube Injeolmi, a kind of traditional Korean glutinous rice cake. The jujube Injeolmi was prepared with glutinous rice soaked for various times (2, 4, 6, 8, 10 hr), and the moisture content, chromaticity, sensory qualities and mechanical qualities were measured while storing them up to 72 hr at 20$^{\circ}C$. The moisture content and L-value of jujube Injeolmi were the highest at 8-hr soaking. The a-value was the highest at 6-hr soaking. The hardness was maintained the lowest at the 8-hr soaked sample during storage. The cohesiveness and springiness were not significantly affected by the soaking time. The gumminess was significantly different among the samples during storage. The results of sensory evaluation showed that jujube Injeolmi had the best color at 4-hr soaking and the highest sweetness at 6-hr soaking. The 8-hr soaked glutinous rice gave the highest level of softness, chewiness and moistness in the sample, therefore, 8-hr soaking appeared to be the most desirable method for making jujube Ingeolmi.

Physicochemical and sensory characteristics of the green tea dasik varying the added value of oligosaccharide were investigated and the products were surveyed by elementary school students regarding the acceptability. Protein and ash contents were significantly higher and fat contents were significanlty lower in the samples with oligosaccharides compared to those in commercial ones(p<0.05). Commercial samples had significantly higher values in all of the textural characteristics using textural analyzer compared to those of the developed dasik sample groups. In analytical sensory evaluation, varying the amount of oligosaccharide, commercial samples had significantly higher values of sweetness, hardness, and cohesiveness and lower values of savory aroma and falvor compared to those of developed dasik(p<0.05). Savory aroma and flavor were highly negatively correlated with textural hardness, springiness, chewiness, gumminess, and cohesiveness(p<0.01), while sensory sweetness and hardness were significantly positively correlated with textural springiness(p<0.05), chewiness, gumminess, and cohesiveness(p<0.01). When surveying elementary school students regarding the acceptability of green tea dasik and commercial samples, green tea dasik 2 was the most preferred with significance in color. Regarding aroma, green tea dasik 1 received the highest acceptability (p<0.05). In the flavor, both dasik 1 and 2 received higher score than those of the commercial dasik. In overall acceptability, both green tea dasik 1 and 2 were preferred to the commercially sold ones with significance(p<0.05).

This study was conducted to investigate the physicochemical characteristics and sensory qualities of saccharified cherry tomato gruel with different ratios of cherry tomato by rice mash. Saccharified cherry tomato gruel containing 0, 15, 30 and 45% cherry tomato puree was prepared and proximate compositions, sweetness, pH, acidity, color, texture, free sugar and sensory analysis of the samples were measured. With increasing cherry tomato puree content, proximate compositions, sweetness and acidity of cherry tomato gruel increased, and pH decreased significantly p<0.05). Saccharified cherry tomato gruel prepared with 15-45% cherry tomato puree displayed significantly lower viscosity. As the level of cherry tomato puree increased, L-value decreased, whereas the a-value and b value increased. Free sugar contents of fructose and glucose contents increased while maltose content decreased. Free sugar content of cherry tomato rice gruel was ranged of 1.44-2.12, 0.53-1.66 and 0.49-0.86 respectively. Cherry tomato rice gruel with 30% added cherry tomato puree was the most preferred for color, flavor, taste, mouth feeling, texture, overall acceptability preference. From these results, we found that adding 30% cherry tomato puree was the best to make gruel with high sensory quality.
