  • This study aims effective use of soymilk residue, by-product of soymilk production, and making noodles by mixing soymilk residue with wheat flour. The results of viscosity property, cooking test of dry noodles, texture test of cooked noodles, and sensory test of cooked noodles were as follows. The color of cooked noodles were slightly shifted to yellowness according to the mixing of soymilk residue. The mixing of soymilk residue resulted in the decrease of texture and the loss of solids due to the decrease of visccelasity. Na-alginate, Na-C.M.C., guar gum, and crude gluten were added to improve the texture of noodles mixed with soymilk residue. As the results, either Na-alginate or guar gum was very effective in increasing the viscosity of composite flour and either guar gum or crude gluten was very effective in improving cooking quality. The texture of noodles supplemented by Na-alginate 1.0%, Na-C.M.C. 2.0%, guar gum 0.5%, or crude gluten 2.0% was similar to that of wheat flour noodles. Complex additives mixed with two different additives were very effective in improving noodle-making characteristics. Especially, the properties of the soymilk residue mixed noodles supplemented by crude gluten 1.0% and Na-C.M.C. 1.0% or crude gluten 1.0% and gum 0.5% were nearly the same in the texture organoleptic properties compared with those of wheat flour noodles.

  • Texture properties of a Korean rice cake (Karedduk) added with carbohydrate materials after 0, 2, 6, 24 and 30 hrs of storage at $5^{\circ}C$ were investigated using textural characteristics and sensory descriptive analysis. Carbohydrate materials such as powdered sugar, trehalose, fructooligosaccharide (95%), isomalto, healtholigo, and galactooligosaccharide (50%) were added in 0, 1, 5 and 10% levels to dry rice flour. The texture profile analysis by Texture Analyzer revealed that adhesiveness and cohesiveness of the Korean rice cake (Karedduk) added with carbohydrate materials were similar to those of the control in trends, while hardness was low compared to the control except for fructooligosaccharide (95%) 5% and healtholigo 1% addition. The hardness and sweetness by sensory characteristics were significantly different compared to the control. Instrumental hardness was correlated with sensory hardness. Lastly, the Korean rice cake (Karedduk) added with carbohydrate materials except fructooligosaccharide (95%) 5% and healtholigo 1% addition was effective in delaying retrogradation.
