This study evaluated the quality characteristics of wet noodles added with sword bean powder(0, 5, 10, 15%) to determine the most preferred noodle recipe for consumer’s desire. The proximate composition of the sword bean powder was as follows: Moisture contents were 13.4±0.08%, protein 30.2±0.12%, fat 0.3±0.09%, protein 1.0±0.11% and carbohydrates 55.1±0.12%, respectively. Total amino acid content of sword bean powder was measured 23,054.266 mg/ 100 g, especially in the order of histidine, glutamic acid and aspartic acid. The flavonoid content of sword bean powder was 17.9750 mg%. Water-binding capacity increased as the level of sword bean powder increased. When viscosity of wheat flours containing sword bean powder was measured by amylograph, the gelatinization point increased significantly as the level of sword bean powder increased, but peak viscosity decreased. As the level of sword bean powder increased, L value decreased, whereas a and b values increased. Weight, water absorption and volume of cooked noodles prepared with wheat flours containing sword bean powder decreased, whereas turbidity of soup increased. For textural properties, addition of sword bean powder increased hardness, springiness, chewiness of cooked noodles, whereas adhesiveness decreased. According to sensory evaluation such as appearance, color, flavor, taste, texture, overall preference, it was revealed noodles with 10% sword bean powder was the most preferred. According to the results, the addition of sword bean powder positively affects the overall sensory evaluation of wet noodle, and 10% is the optimal level for addition.

The objectives of this study was to investigate the properties and stability of the wet noodles added to nanoemulsion as a industrial model system, and in so doing, survey practical applicability in the food industry. In order to test out these objectives, the characteristics and stability of the wet noodles added to nanoemulsion were investigated and their cooking characteristics and capsaicinoids loss were examined. As a result, the test results showed that the findings indicated that the post-cooking loss of capsaicinoids in the wet noodles added to double-layer nanoemulsion covered with chitosan was less than the losses in the wet noodles added to any other noodles. More especially, this demonstrates that the noodle added to double-layer nanoemulsion covered with chitosan scored significantly higher than the others with reference to their cooking properties, color, texture, stability for storage stability, and sensory evaluation. These results show that the findings of this study demonstrated that the noodles added to nanoemulsions could be produced as a food-grade merchandise because they could provide enhanced encapsulation capacity of capsaicinoids and higher acceptability.

A study was conducted for optimization of the process for the manufacture of raw noodle added with leaf powderof Cirsium setidens Nakai, which is rich in various minerals and dietary fibers along with intrinsic antioxidativeproperties. The level of leaf powder, water content, and kneading time of the dough were selected as three majorfactors affecting quality of the product. Quality parameters of the product such as color, texture, water absorptionratio, volume, turbidity of cooking water, and sensory evaluation result were analyzed as dependent variables. D-optimum design of the complete RSM analyses was adopted for designing the optimum noodle manufacturing pro-cedure. Ranges of the independent variables as determined through preliminary experimental work were level of leafpowder, 2-9% (w/w, wheat flour); moisture content, 40-50%; and kneading time, 7-20 min. Within the given rangesof these independent variables, 18 experimental points included in four repetitive runs were obtained for the anal-yses. The optimum conditions that together satisfy the quality parameters of the raw noodle, as based on the numer-ical and graphical statistical analyses, were amount of leaf powder, 5.76%; water content, 42.52%; and kneadingtime 13.86 min. The complete RSM analysis for manufacture of the high quality raw noodle with an added ingre-dient is suitable for similar application to other products in the industry.

This study was conducted to investigate the properties of wet noodle when different concentrations of Prunus mume juice were added to the wheat flour. The characteristics of wet noodle including cooking properties, color, mechanical texture properties, and sensory quality were determined. The compositions of Prunus mume were 88.19% moisture, 0.45% crude ash, 4.04% citric acid and 0.41% total sugars. The pH of Prunus mume was 2.76. The moisture absorption rate, weight, volume and turbidity of cooked noodles added with Prunus mume juice were lower than reference sample. When the amount of Prunus mume juice increased, the Hunter L(brightness) value, a(redness) value of cooked noodles decreased but b(yellowness) value increased. Instrumental rheological characteristics of wet noodle containing Prunus mume juice were measured with a texture analyzer. The hardness, adhesiveness, cohesiveness, springiness and gumminess of wet noodle with 20% Prunus mume juice were higher than others. However, the hardness of cooked noodle decreased with the increase in the amount of Prunus mume juice into noodle. The adhesiveness, cohesiveness, springiness and gumminess of cooked noodles added with Prunus mume juice were higher than reference sample. The results of sensory evaluation of cooked noodles containing Prunus mume juice indicated that the appearance, color, taste and chewiness of the cooked noodle with 10% Prunus mume juice showed the higher preference than others. Based on cooking properties, rheological and sensory evaluation, addition of 10% Prunus mume juice suggested to be acceptable for processing wet noodle.

The effect of addition with maesil(Prunus mume) juice for extending the shelf-life of wet noodle was investigated by measuring quality changes such as total microbial count and pH. The Prunus mume juice showed antimicrobial activities against Salmonella enteritidis, Staphylococcus aureus, Bacillus cereus, Listeria monocytogenes, and Escherichia coli. When the wet noodles containing Prunus mume juice were kept at 4℃ for 20 days, it was showed that the drop of pH was not significantly occurred during the storage. Total microbial counts for control exceeded the initial putrefactive criterion level of 1.0×106 cfu/g at 16 days of storage at 4℃. However, total microbial count of wet noodles with the addition of 10%, 20% and 30% Prunus mume juice were 3.0×102 cfu/g, 3.0×102 cfu/g, and 1.5×102 cfu/g, respectively, and these bacterial counts were still less than the criterion level ever at 20 days of storage. The addition of Prunus mume juice extended the shelf-life of wet noodle appreciably.
