A study was conducted to compare the quality characteristics among commercial broiler, Wangchoo (imported dual purpose breed) and Korean native chicken(KNC). Thigh and breast meat of the broiler(7-wk old), Wangchoo(15-wk old), and Korean native chicken(15-wk old) stored for 24 h at 5t were used to analyze chemical composition, physico-chemical characteristics, textural traits and sensory evaluation test. Crude fat and moisture contents in broiler meat and crude protein content in KNC were significantly(P<.05) higher than those in the other breeds regardless of parts of the body. Total collagen content in broiler meat was significantly higher than those of the other breeds, however, the heat-soluble and the acid-soluble collagen content in Wangchoo were significantly lower than those of the other breeds. Water-holding capacities of KNC in breast meat, and of broiler in leg meat were significantly higher than that of the other breeds, while the results of the water-holding capacity and the cooking loss were reversed. Myofibrillar fragmentation index in broiler meat was significantly higher than that in the other breeds regardless of body parts. Hardness, elasticity and cohesiveness in Wangchoo were significantly higher than those in the other breeds. The prominent fatty acids were oleic, palmitic and linoleic acids and run up to 79.03~83.82 %, regardless of breeds and parts. The sensory evaluation score of tenderness, taste and preference in Wangchoo were lower compared to the broiler and KNC, however, they were not significantly different between broiler and KNC. In conclusion, the quality characteristics of KNC were excellent compared to Wangchoo.

In this study, the quality characteristics of tofu prepared with added spirulina(0, 0.25, 0.5, 0.75, and 1%). As the concentration of spirulina increased, tofu yield decreased and the pH and turbidity increased. The Hunter L(lightness) and a(redness) values of tofu decreased as the amount of spirulina increased. Phycocyanin(C-phycocyanin, allophycocyanin and phycoerythrin) contents increased according to the spirulina amount. Moreover the antioxidant activity of tofu increased as the concentration of spirulina increased($IC_{50}$ values for control was 150.7 mg/g; 1% spirulina, 82.5 mg/g). Textural properties(TPA) for hardness, gumminess, and chewiness were higher in spirulina with added tofu, compared to those of control. Regarding the overall acceptability of sensory properties, spirulina with 0.5% added tofu had the highest scores among all treatments. From these results, it was suggested that the optimal amount of added spirulina was 0.5% for the preparation of high quality tofu.

Sulgidduk is a steamed 'Dduk' that is made from rice flour mixed with various ingredients. It is steamed in an earthenware steamer according to a particular procedure. Soyflour Sulgidduk was prepared with two types of soyflour(yellow, and black). This study was carried out to improve the quality of Sulgidduk. The quality was affected by not only the ratio of the ingredients, but also by the amount of soyflour. The results of these experiments can be summarized as follows. As the amount of soyflours(yellow and black) increased 10 %, 20 %,30 %, and 40 % into the control recipe, it was found that the overall rheological properties, such as hardness, gumminess, brittleness, cohesiveness, and springiness, of Sulgidduk decreased. The L-value of the color decreased as more soyflour was added into Sulgidduk but the b-value increased. When the same amount of black soyflour was added to Sulgiddut addition of black soyflour produced lower lightness than yellow soyflour addition. Yellow soyflour addition into Sulgidduk yielded a higher a-value, closer to red. As the results of sensory evaluation, following to the added amount of soyflour, the sensory degree of flavor, moistness, and chewiness of Sulgidduk decreased. The addition of 20 g soyflour resulted in the best overall quality based on sensory evaluations. Therefore the optimum recipe of Soyflour Sulgidduk was obtained as follows; 20 g(20%) soyflour, 80 g rice, and 20 mL water.

This research focused on investigating the effect of lentinus edodes on the Garaedduk by analyzing its quality characteristics. Through this research, it could be verified whether this improved food has the potential to develop into a functional food. 5 pieces of Garaedduk with 0, 2, 4, 6, and 8% of lentinus edodes powder were analyzed by water content, color, sensory, textural characteristics and cooking characteristics right after the production and after one day. The five Garaedduk showed significant differences in water content during storage period of 0 & 1 day. As the result of Hunter's color values, with the increase of lentinus edode during storage period of 0 & 1 day, lightness was significantly decreased and redness and yellowness were significantly increased. As the result of textural analysis, hardness and chewiness showed significant increase and cohesiveness was significantly decreased in Garaedduk with the increase of lentinus edodes. When the Garaedduk were preserved for one day, the hardness and chewiness of the Garaedduk with 2% of lentinus edodes showed similar with the control. Cohesiveness showed significant decrease in all Garaedduk. The result of the sensory evaluation showed increase in the color, aroma and taste with the increase of lentinus edodes. The 2% Garaedduk showed similar hardness with the control. Garaedduk with lentinus edodes showed no difference in cohesiveness and adhesiveness with the control. The overall acceptability was significantly increased with the increase of lentinus edodes while the Garaedduk with 6% of lentinus edodes showed the highest overall acceptability. After one day of preservation, the Garaedduk with 4% lentinus edodes also showed the highest overall acceptability. As the result of cooking properties, weight gain and volume were significantly increased with the increase of lentinus edodes. The 2% Garaedduk particularly showed similar weight gain with the control. In turbidity of soup was significantly increased with the increase of lentinus edodes. In Hunter's color values of soup, lightness was significantly decreased with the increase of lentinus edodes. Redness and yellowness were significantly increased with the increase of lentinus edodes like Garaedduk.

In this study, frying mix was prepared containing 0.5, 1.0, 1.5 or 2.0% brown rice fiber(BRF). The samples along with a control were then compared regarding their quality characteristics, including pasting properties, spreadability, pick-up ratio, color, textural characteristics, moisture and oil contents, and sensory qualities, all to determine the optimal ratio of BRF. For the pasting properties of frying mix, the control group was evidenced by a significantly higher peak viscosity, through viscosity, and final viscosity than that observed in the BRF samples. Breakdown was the highest at the 1.0% addition level, and time to peak viscosity and pasting temperature were maximal with the 0.5% addition. There was no significant difference in setback among the experiments. Spreadability and pick-up ratio of frying batter were not significantly different among the samples. As the BRF content increased, the lightness, greenness decreased, whereas yellowness increased. The BRF samples presented significantly higher hardness of fried batter than the control group and there was no significant difference in crispiness among the samples. Moisture content of fried sweet potato decreased with increasing BRF and oil content was the maximum on the control group. In the sensory evaluation, appearance, color, flavor, savory taste, yellowishness, coating thickness, off-flavor, and oiliness were not significantly different among the fried sweet potato samples. Bindingness, crispiness, and chewiness were highest in the control samples but minimal at a addition level of 2.0%. The control group evidenced significantly higher overall acceptability than were observed in the BRF samples. In conclusion, the results demonstrated that 0.5~1.0% BRF may prove quite useful as a additive for frying mix in the preparation of fried sweet potato and may provide favorable textural and functional properties.

The objective of this study was to investigate the effect of using gelled emulsion (olive oil 46%, inulin 9%, gelatin 3%) as fat replacer on some quality parameters of chicken patties. For this purpose GE, prepared with olive oil, gelatin and inulin was replaced with beef fat at a level of 0%, 25%, 50%, 100% (C, G25, G50, G100). In this study syneresis, thermal stability, centrifuge and creaming stability of gelled emulsion were analyzed. Chemical composition, technological paramerers (cooking yield, water holding capacity, diameter reduction, fat and moisture retention) and textural and sensory properites were evaluated in comparision to control patties. High thermal stability was recorded in GE (93%), also creaming stability results showed that GE protected its stability without any turbidity and separation of the layer. The complete replacement of beef fat with GE showed detrimental effect on all investigated cooking characteristics except fat retention. Replacement of beef fat with GE at a level of 50% resulted similar cooking characteristics with C samples. Color parameters of samples were affected by GE addition, higher CIE $b^*$ values observed with respect to GE concentration. The presence of GE significantly affected textural behaviors of samples (p<0.05). Our results showed that GE prepared with inulin and olive oil is a viable fat replacer for the manufacture of chicken patty.
