  • The purpose of this study is to develop fresh pasta added with superjami, which had a high C3G (cyanidin-3-glucoside). Making fresh pasta with wheat flour and superjami(0, 10, 20, 30, 40%) was done, followed by the mechanical test(moisture content, color value, weight, volume, texture, tension) and the sensory analysis(attribute difference test, preference test). Results are as follows. Moisture content of fresh pasta and cooked pasta was the highest in SP40, and the scores of cooked pasta was much higher than those of fresh pasta. L, a and b value decreased as the ratio of superjami powder. Hardness, chewiness and tension force decreased, while weight, volume, adhesiveness and tension distance increased as the ratio of superjami powder. Attribute difference test showed that color intensity, superjami flavor, savory flavor, superjami taste, savory taste, graininess and after swallow were intense as superjami powder was added. The preference test showed that SP20 containing 20% of superjami powder was the most preferable in flavor, taste, texture and overall quality. Therefore, this was taken as the optimal superjami powder contents for maximizing the overall quality of fresh pasta.

  • Transglutaminase (TG) was prepared from Streptomyces mobaraensis to improve texture and self-life of food. In preliminary experiments, texture of the dough was not improved due to the interference in microbial TG reaction by proteases present in the crude enzyme. Among the cation exchange resins tested for the removal of proteases, MonoPlus S 100 was the most efficient. Further purification steps with a quaternary ammonia salt resin and gel permeation chromatography effectively removed proteases from crude enzyme. Molecular weight of purified enzyme was about 38,000 on SDS-polyacrylamide gel electrophoresis. Farinograph data showed the addition of purified enzyme to wheat flour gave higher stability and lower weakness values those that of crude enzyme.

  • The wet soybean residue, a byproduct of soymilk industry having potential food value has been tried to dehydrate for the purpose of storage. The total solid of the byproduct was composed of 28.9% protein, 13.6% fat, 4.4% ash and 53.0% carbohydrates. The original water content of 593%(dry-weight basis) was reduced to 378% by pressing mechanically. The sufficient pressure and time for the pressing were found to be 0.5M/T and 5minutes, respectively. The partially dehydrated soybean residue was formed into pellets of 3mm in diameter and 10mm in length. By applying hot air on the thin layer of pellets the moisture could be further reduced to the level of 10% which is equivalent to that of the commercial wheat flour. No significant color deterioration in the product was observed if the hot air dehydration procedure was within the limit of 95 minutes at $120^{\circ}C$ under the air flow velocity of 160 feet per minute.

  • A method for the measurement of viscoelastic properties of heat denatured gluten network was developed in order to evaluate the noodle making quality of wheat flour. The stress relaxation of elongated heat denatured gluten network could be expressed by 6-element generallized Maxwell model. The tensile force of heat denatured gluten network increased by the heating time. The elastcity and viscosity of the first exponential term which covers 70-74% of the total relaxation increased as cooking time was extended up to 1q min. The addition of gluten network strengthening agent, potassium bromate, at 1000ppm level reduced the elasticity and viscosity, while weakening agent, L-cystein, increased them. The relaxation time decreased after 11 min of cooking in both cases. The elasticity and viscosity of heat denatured gluten were affected differently by the concentration of added urea.

  • White breads containing Korean blue mussel (Mytilus edulis) powder were prepared and characterized. WB (white bread without blue mussel) and four different MBs (white breads containing blue mussel; number in front of MB means added % of blue mussel powder per wheat flour) were prepared by the straight dough method. With addition of blue mussel to bread, lightness decreased, whereas redness and yellowness increased. Addition of blue mussel did not significantly affect specific volumes of breads. DPPH and ABTS radical scavenging activities significantly increased with increasing blue mussel content. Addition of blue mussel to breads also increased alcohol dehydrogenase and acetaldehyde dehydrogenase activities. In the sensory test, 1MB acquired relatively high points for taste, flavor, texture, and preference. The results indicate that blue mussel can be applied to white bread to improve physiological functions without reduction of physicochemical characteristics.

  • Effects of various concentrations of garlic powder and garlic extract in the diets on growth, serum chemistry and immune response of olive flounder were determined. Thirty-five juvenile fish averaging 5.1 g were randomly distributed into 21 of 180 L flow-through tanks. Seven experimental diets with various concentrations of garlic powder (GP) and garlic extract (GE) were prepared in triplicate: GP-0 without garlic supplementation, GP-0.5, GP-1, GP-2, GP-3 and GP-5 diets containing garlic powder at the concentrations of 0.5, 1, 2, 3 and 5%, respectively at the expense of wheat flour and finally, GE-0.4 diet containing 0.4% garlic extract were prepared. At the end of the 8-week feeding trial, serum chemistry of fish was measured. In addition, twenty fish from each tank were artificially infected with E. tarda for the following 96 h to monitor cumulative mortality. Weight gain of fish fed GP-0 diet was higher than that of fish fed GP-1, GP-2, GP-3 and GP-5 diets. No difference in serum criteria (total protein, glucose, glutamate oxaloacetate transaminase, cholesterol and triglyceride levels) of olive flounder was found among the experimental diets except for glutamate pyruvate transaminase. Lysozyme activity of fish fed GP-0, GP-1, GP-3 and GE-0.4 diets was higher than that of fish fed GP-5 diet. The highest cumulative mortality was 93.3% in fish fed GP-0 diet at 96 h after E. tarda infection, followed by GP-3, GP-1, GP-5, GP-2, GP-0.5 and GE-0.4 diets. In considering these results, dietary inclusion of garlic powder and garlic extract has no distinctive positive effect on improvement in growth, serum chemistry and immune response of olive flounder in this experimental conditions, therefore, its application should be carefully considered.

  • The principal objective of this study was to assess the quality properties of noodles to which browned oak mushroom (Lentinus edodes) paste was added at concentrations of 10%, 20%, and 30% to wheat flour, respectively. With regard to the cooking properties of the noodles, the weight and water absorption of the cooked noodles increased with increasing paste contents, but the turbidity of the noodle soups decreased (p<0.05). The hardness and gumminess of the uncooked and cooked noodles decreased significantly in proportion to the quantity of added paste, except in the case of the cooked noodles with 30% paste. The springiness and cohesiveness of both noodles with Lentinus edodes paste were significantly higher than in the controls. The lightness of the uncooked and cooked noodles decreased in accordance with the amount of added paste. However, the yellowness of both noodles was significantly increased. Moreover, the results of our sensory evaluation showed that the cooked noodles with 20% and 30% added Lentinus edodes paste had higher values. Thus, Lentinus edodes paste added to a concentration of up to 30% was shown to effectively improve the quality of noodles.

  • Effect of baking on the physicochemical properties including pH, moisture content, hardness, color, and spread factor was investigated using a model system of cookies incorporated with strawberry powder as a value-added food ingredient. Strawberry powder was incorporated into cookie dough at 4 levels (0, 2, 4, and 6% w/w) by replacing equivalent amount of wheat flour of the cookie dough. After aging and sheeting, cookies were baked at 170$^{\circ}C$ for 15 min in an oven. The baked cookies were cooled to room temperature for 1 hr and packed in airtight bags prior to all measurements. The pH of dough and hardness of cookies decreased significantly with increase in strawberry powder content (p<0.05). Moisture content of the dough was not significantly affected by strawberry powder but mean values tended to increase as the strawberry powder content increased. Lightness (L$^{*}$-value) and yellowness (b$^{*}$-value) significantly decreased as the strawberry powder content increased; on the other hand, redness (a$^{*}$-value) increased significantly (p<0.05). Spread factor also increased significantly as the strawberry content increased in the formulation (p<0.05). Finally, correlation analysis indicated that level of strawberry powder incorporation was well-correlated with all the physicochemical properties studied. It is also noted that there was a significant positive correlation between the moisture content of dough and spread factor (p<0.05).
