  • The effects of replacement of wheat flour with laver, Pyropia yezoensis, on the bread making properties and quality characteristics of bread were evaluated. The poor baking performance which arose from dried laver addition could be compensated by using exogenous enzymes (Flavouzyme) and baking aids. Laver hydrolysate was prepared by hydrolyzing laver using Flavouzyme for 9 hrs at $50^{\circ}C$. Doughs made by addition of laver hydrolysate (8% dried laver substitution level) showed excellent baking properties. Moreover, with the addition of glucose oxidase and hydro colloidal HPMC, loaf volume and crumb grain were improved for doughs containing laver hydrolysate. Both of intermediate fermentation and final proof time for doughs containing laver hydrolysate was shorter than that for conventional dough.

  • A feeding trial was conducted for 60 days to study the utilization of fruits processing wastes as feed ingredient in the diet of Labeo rohita fingerlings. One hundred and sixty fingerlings (av. body weight, $1.65g{\pm}0.03$) were equally distributed in four experimental groups having 4 replicates each. Four different experimental diets were prepared by replacing wheat flour and rice bran with either orange (T2) (Cirtus qurantium), pineapple (T3) (Ananas spp. and Pseudananas spp.) or sweet lime (T4) (Citrus sinensis) wastes to the basal diet along with the control (T1, without any fruit wastes) keeping the CP level at around 40%. The water quality parameters like DO, $CO_2$, pH, total alkalinity, total hardness, ammonia and water temperature were recorded within the optimum range. The diet containing 25% pineapple wastes (T3) showed significantly higher growth in terms of SGR (1.50), FCR (2.09) and PER (1.19) than the other groups. However, growth of T4 and T2 groups were not significantly different than the control group (T1). Protease activity (17.17 unit/mg protein), protein digestibility (91.57%) and carbohydrate digestibility (41.62%) were not significantly different among the different groups. Survival of the fingerlings were not significantly different among the experimental groups. It concludes that waste of orange, pineapple and sweet lime can be used at 25% level as a substitute of wheat flour and rice bran in the diet of Labeo rohita.

  • Wet noodles with different percentages of Curcuma Ionga L. powder(CLP) as an additive were generated and their cooking characteristics were evaluated. Wheat flour with 8% CLP had the highest water binding capacity and breakdown, while setback was reversed. Cooked noodle characteristics, weight, volume and tensile strength decreased as CLP content of wheat flour increased, but turbidity of the soup was reversed. L value of wet noodles was higher than cooked noodles, while b value, and texture of wet noodles were lower than cooked noodles. Hunter color value and texture measurements demonstrated decreasing L value, springiness and cohesiveness but increasing b value, hardness, gumminess and chewiness with increasing CLP content. In sensory evaluations, noodles made with 4% CLP were most highly preferred, while noodles made with 2% and 8% CLP were less preferred than CLP-free prepared noodles.

  • Castella sponge cake was prepared by partially replacing wheat flour with Chungkukjang, a Korean fermented soybean. The physico-chemical, textural and sensory characteristics were then investigated. Specific volume and expansion ratio decreased with increasing Chungkukjang content. The addition of Chungkukjang decreased the moisture content and increased the protein content of castella. Color determination showed addition of Chungkukjang darkened the internal color of castella, probably due to browning caused by the Maillard reaction. Castella with 20 or 30% Chungkukjang had a higher textural hardness than other castellas. A sensory panel perceived that the external and internal color of castella darkened with Chungkukjang substitution. When Chungkukjang was added at or above 20%, castella had a weaker sweet flavor, a stronger roasted flavor, and less lightness and softness than other castellas as perceived by the sensory panels. Up to 30% of the wheat flour could be replaced by Chungkukjang without diminishing acceptability.

  • Sun-cuisine is a traditional Korean side dish. This study examined the methods used to prepare Sun-cuisine in 11 Korean recipe books published over the last 100 years. The main ingredients of Sun-cuisine were typically vegetables, fins, fur, feathers, meat, legumes and mushrooms dipped in wheat flour or mung bean starch powder and stuffed with various minor ingredients known as "so". These dishes are highly seasoned and boiled in meat stock or steamed in a double boiler, after which they were sprinkled with toppings. Various materials are used as the main ingredients. When vegetables were used as the main ingredients, they were sprinkled with salt, sliced and stuffed with beef or mushrooms. Meat stock was then poured on top of the vegetables and they were steamed. A total of 38 food materials were used as the minor ingredients, while 25 materials were used as seasonings and six foods were used as toppings. Pine nuts were widely used as a minor ingredient, seasoning and topping. Sun-cuisine is generally made using various powders such as starch or wheat flour. Sun-cuisine was a kind of royal court food in the past that was served as a side dish. Recently, Sun-cuisine is eaten less often because its cooking process is too delicate and complicated. Therefore, additional studies to enable the modernization of the Sun-cuisine cooking process should be conducted with the goal of revitalizing the beauty and taste of this traditional food.

  • The aim of this study was to use arrowroot powder to develop a recipe for a nutritional cookie having the optimal composition of ingredients and texture to elict a strong preference response in all age groups. Wheat flour was partially substituted with arrowroot powder to reduce the wheat flour content of the cookie. Measurements were made and analyzed according to the Response Surface Methodology technique, which showed 16 experimental points including 2 replicates for arrowroot powder, yellow sugar and butter. The compositional and functional properties of the test were measured, and the values obtained were applied to a mathematical model. A canonical form and perturbation plot showed the influence of each ingredient on the final mixture product. The result of sensory evaluation showed very significant values for color (p<0.01), appearance (p<0.001), texture (p<0.05), overall quality (p<0.05), and flavor (p<0.05). Instrumental analysis showed significant values for lightness (p<0.001), redness (p<0.01), yellowness (p<0.01) and spread ratio (p<0.001). The optimal sensory ratios were determined to be 15g for the arrowroot powder, 70 g for sugar and 80 g for butter.

  • Effects of Takju(Korean turbid rice wine) lees on noodle investigated by substituting Takju lees water extract powder for each 2% and 4% wheat flour in sample II and III, respectively. The lightness(L) of uncooked noodles was decreased, whereas that of cooked noodles was increased with increasing amount of extract added. Redness(a) and difference of total color(${\Delta}$E) were significantly increased according to the amount of extract added in uncooked and cooked noodles. Yellowness(b) of the noodles containing 2% Takju lees water extract powder was exhibited lowest values in uncooked and cooked noodles. In cooking property of noodles, turbidity of soup decreased in proportion to amount of extract added, 2% and 4% in sample II and III, respectively whereas the weight and volume of noodles were not significant than those of control. Tension of cooked noodle was highest in sample II and lowest in sample III. Texture profile analysis of cooked noodle showed an significant increase of hardness in addition of Takju lees water extract powder but not significant different in springiness, chewiness, adhesiveness. Cohesiveness was significantly lowest in sample II. The sensory evaluation showed that significant difference between noodles with 2% addition groups and control was not recognized but was recognized 4%. Therefore, based on cooking properties and sensory evaluation, Takiu lees water extract powder up to 4% could be substituted for wheat flour.

  • Husked barley contained 17.2% dietary fiber and naked barley contained 14.9% dietary fiber. The barley was ground in a Udy cyclotec mill having a 0.5 mm screen and sieved with a 400-mesh screen (38 m openings). Coarse material of naked barley retained by the screen, with a weight yield of 54.1%, contained 7.0% soluble dietary fiber, 13.9% insoluble dietary filer and 20.9% total dietray fiber. As the naked barley flour level increased in bread baking, the water absorption, mixing time, and loaf weight increased, but the loaf volume decreased. Barley flour was added to wheat flour at a replacement level of 10% without a large adverse effect on bread quality, and the dietary fiber content of bread was increased from 3.0% to 5.0%. The soluble dietary fiber content was not changed, but the insoluble dietary fiber content was increased during the baking process.
