This study was aimed to determine the cooking properties of noodles when dfferent concentrations of Aster scaber THUNB(AST) juice were added to the buckwhenat and wheat flours. Also, physicochemical effects of the noodles and compositions of the noodles and compositions of the noodle soup after cooking were determined. Buckwheat flour and AST contained greater amounts of minerals and essential amino acids than wheat flour. The contents of chlorophyll and carotenoids in the buckwheat noodle added AST juice increased as the concentrations of AST juice increased. Hydration capacity of buckwheat flour was higher than that of wheat flour when AST juice was added to flours. The added amounts of AST juice did not affect the volume and the weight of the noodles, but those were increased as cooking time proceeded. The release of proteins and minerals from the buckwheat noodle added AST juice increased as cooking time progressed and also at the added concentrations of AST juice increased. Texture indices showed lower values as the amount of added juice increased. In sensory evaluation, the scores of color, flavor and overall acceptability of the buckwheat noodle added AST juice were higher than those of the control.

The effect of using Korean wheat flour versus Australian wheat flour on noodle quality as a result of differing physical and chemical properties of the flours was investigated. The results provided appropriate technical information for selection of wheat varieties to produce high quality Korean salted noodles. Noodle quality was quantified based on measurement of the appearance and texture of noodles. When consumer preference tests were conducted, a firmer and more elastic texture was preferred for Korean white salted noodles, however, when appearance was included in the consumer tests, noodles made with Australian wheat were favored over Korean wheats. Korean flour was found to produce firmer and more elastic noodles, whereas Australian flour produced brighter, creamier colored noodles. In flour quality tests, Korean flours were found to have a higher setback viscosity and lower swelling power than Australian flour. Additionally, Korean flours had higher water absorption values. Protein content of flour was an important parameter affecting the firmness of Korean noodles, whereas setback viscosity and swelling power were the major determinants of elasticity. Overall, the important parameters for determination of the quality of Korean salted noodles were high setback viscosity, low swelling power, and high protein content.

This Study was conducted to investigate the processing quality of high-amylose content rice(goami) flour for noodle. The potassium and magnesium contents of rice flour were negatively associated with gross score of noodle making mixed with wheat flour. The high-amylose content of rice flour was closed associated with gel consistency negatively and with hardness of rice noodle positively, Setback viscosity of rice flour measured in a rapid visco-analyser(RVA) was significantly affected by amylose content as well as gel consistency. Also the amylose content decreased, the amylogram pasting temperature and the breakdown ratio increased. The low-amylose content rice(Chucheong) flour showed higher values in solubility. Cooking quality and texture were measured, and sensory evaluation was performed with the noodles prepared. Texture measurement showed that the noodles of composite flour containing 40% goami rice flour were superior to those wheat flour alone. Water binding capacity of the composite flour containing 40% goami rice flour was lower than that of 40% chucheong rice flour. In sensory evaluation, chewiness, overall acceptability of noodle with 40% goami ricer was evaluated as the best.

This study was tried to evaluate possibilities for discriminating the mixture degree of wheat flour from buckwheat products. Buckwheat was milled into four grades of powder, i.e. whole grain flour (WGF), inner layer flour(ILF), middle layer flour(MLF) and outer layer flour(OLF)), and these powders were mixed with wheat flour(WF) to make mixed samples. Ash, protein and fat contents of the buckwheat flours were high in the order of OLF=WGF>MLF>ILF. On the other hand, WF showed a similar content to OLF in ash and protein, and to ILF in fats. Potassium and magnesium contents were higher in all the buckwheat powder than in the wheat flour. Flavonoid contents were higher in order of OLF>WGF=MLF> ILF, but it was not in wheat flour. Although the reliable correlation between mix ratio and components, i.e. mag nesium or ash analyzed were found, it did not seem to reflect sufficiently the expected variations of contents of original material components. Also, compositions of commercial buckwheat products were analyzed to evaluate the mixed ratio of buckwheat flour and wheat flour. The results suggest that the components analyzed in this study as putative marker were not good in determining whether or how much buckwheat products contained wheat flour.

This study was to examine the possibility of making use of the edible portion on the inner layer of chestnut, which is produced as wastes in the chestnut processing, into chestnut-noodle. To conduct this study, the chestnut powder, which is separated and collected from the inner layer, was used to examine the possibility of making chestnut-noodle. The structure of chestnut-noodle was observed by Scanning Electron Microscope (SEM) and the sensory quality was conducted to examine usability of the chestnut-noodle as compared to wheat flour noodle by Quantitative Descriptive Analysis (QDA). The ten sensory qualities : appearance, color, flavor, hardness, elasticity, cohesiveness, adhesiveness, chewiness, gumminess, and acceptability, were evaluated by 10 point Likert type scale with 10-50% of different ratio of chestnut powder. The chestnut-noodle made by 50% of the chestnut powder got higher points than 10 % of chestnut powder mix in color. However, the chestnut-noodle made by 50% of the chestnut powder got lower points than wheat flour noodle in flavor. Finally, there was no significant difference in hardness, elasticity, cohesiveness, adhesiveness, chewiness and gumminess between the chestnut-noodle made by 30% of the chestnut powder and wheat flour noodle.

This study was performed to investigate the quality characteristics of noodles made from four different potato varieties: Atlantic, Go-un, Sae-bong, Jin-sun, and wheat flour. Quality characteristics of five noodles were analyzed by general components analysis, cooking quality (rate of water absorption, cooking loss, and volume increase), and mechanical textural properties. Some variations existed in wheat- or potato-based noodles for the general components analysis, but no clear trend was observed. Higher values in the rates of water absorption, cooking loss, and volume increase were observed for the wheat flour noodle, while some variations were observed for potato noodles depending on the variety. The wheat flour noodles exhibited higher values of textural characteristics obtained from the texture profile analysis, except for adhesiveness. Higher gluten contents as well as lower ash contents in the wheat flour noodles compared to the potato noodles are thought to be the two key factors contributing to this finding.

보리가루-밀가루(중력분) 복합분에 있어서 보리가루 30%수준까지는 면대형성 및 절출등의 제면성이 양호하였고 겉보리가루보다는 쌀보리가루가 약간 우수한 제면성을 보였다. 이때 xanthan gum의 첨가는 이들복합분의 제면성을 향상시켰다. 그리고 쌀보리가루-탈지콩가루 복합분에서는 NSI(Nitrogen Solubility Index)가 높은 탈지콩가루만이 건면을 만들 수 있었으나 대체로 불량한 제면성을 보였다. 쌀보리가루-밀가루 복합분으로 만든 건면의 조리특성은 겉보리가루-밀가루의 그것보다 우수한 경향을 보였으며, xanthan gum의 첨가는 조리중 수분흡수 및 부피의 팽창을 촉진시켰다. 보리가루-밀가루 복합분으로 만든 건면의 조리후견고성 및 gumminess는 보리가루 혼합수준이 60%이상에서만이 밀가루 단독의 경우보다 저하되었으며, 쌀보리가루-탈지콩가루 복합분으로 만든 건면의 조리후 견고성은 특이하게 높은 현상을 보였다.

한국 재래식 국수류인 밀국수와 냉면국수의 점탄성을 연구하기 위하여 실험실에서 tensile시험기계를 만들고 이것을 이용하여 국수발에 대한 creep test를 실시하였다. 밀국수 및 냉면국수 모두 최초 단시간의 creep에서는 선형점탄성(linear viscoelastic)을 나타내었으나 creep시간이 경과함에 따라 비선형 점탄성을 나타내었다. 변형력 범위가 $4{\times}10^4-14{\times}10^4\;dyn\;cm^{-2}$일때 밀국수는 120초간, 냉면국수는 60초간 선형 점탄성을 나타내었다. 2000초 동안의 creep시험에서 추산된 밀국수의 탄성계수(elastic modulus)는 $7.0{\times}10^5\;dyn\;cm^{-2}$이었으며 냉면국수는 $3.9{\times}10^5\;dyn\;cm^{-2}$이었다. 변형력의 증가에 따른 점성변화를 평가한 결과 밀가루 반죽에서 보고된 결과와는 정반대 현상인 stress-hardening 성질을 나타내었다.
