Purpose: This study was to investigate the quality characteristics of wet noodle added with radish juice containing with pulp. Methods: Wet noodles were prepared with different amounts of radish juice (0%, 20%, 40%, 60%, 80%, 100%, w/w) instead of water. Results: As the amount of radish juice was increased, water absorption, volume increasing rate, and turbidity of soup were decreased. Lightness (L) values of uncooked wet noodles and cooked noodles were decreased with the addition of radish juice, while redness (a) and yellowness (b) values had no tendency of increasing or decreasing, regardless of the amount of radish juice. Moreover, lightness, redness, and yellowness values of uncooked noodles were higher than those of cooked noodles. The texture of cooked noodles showed significant differences in hardness and chewiness. It was increased as the amount of radish juice was increased. Their adhesiveness and springiness were lower than those of the control. Appearance, texture, and overall acceptability of sensory evaluation revealed that the noodle added with 80% of radish juice had the highest scores, although there were no differences among noodles added with different amounts of radish juice. Conclusion: In summary, the most desirable blending ratio of radish juice and water for the kneading of wet noodles was 80:20.

For the improvement of the nutritive value of extruded noodles, soybean flour(SF) was mixed with wheat flour. The effects of the addition of SF on the viscosity of wheat flour and the quality of cooked noodles were evaluated. As the proportion of SF addition was increased, the viscosity of composite flour was decreased, And so were the texture and cooking quality of noodles. To improve noodle-making characteristics of extruded noodles with 10% SF, Na-alginate, Na-car-boxymethyl cellulose, guar gum, crude gluten and xanthan gum were added. Then, the noodlemaking characteristics were examined. The viscosity increased with the increase in the concentration of additives and xanthan gum was the most effective. The texture of noodles supplemented by Na-alginate 2.0%, Na-carboxymeihyl cellulose 2.0%, guar gum 2.0%, xanthan gum 1.0% was similar to that of wheat flour noodles. The results of sensory test(color and texture) was coincidal with the results of instrumental tests.

This is a basic study of Cheong-song mineral water, which has high contents of Ca and Mg for making noodles as well as for general cooking. The test results of the noodles manufactured and cooked with mineral water were compared to those manufactured and cooked with distilled water and tap water. Noodles manufactured with mineral water showed higher values than others in the cooked weight, volume, water absorption ability, turbidity, lightness (L) and redness (a) on the minus scale. This means that we can manufacture cooked noodles that have high weight, high volume, high water absorption ability and high lightness (L) along with a slight green color with Cheong-song mineral water. Cooked noodles manufactured with mineral water showed significant differences in the cooked weight and volume compared to those manufactured with distilled water. Also, cooked noodles manufactured with mineral water showed significant differences in moisture absorption, turbidity, lightness (L), redness (a) and yellowness (b) compared to those manufactured with distilled water and tap water. Commercial noodles cooked in mineral water showed significant differences in the cooked weight and redness (a) compared to those cooked in distilled water and tap water. Further, commercial noodles cooked in mineral water showed significant differences in weight, volume and brightness (L) compared to those cooked in distilled water.

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.

In this study, the quality characteristics of noodles containing different amounts of germinated black quinoa were investigated. The powder of black quinoa with the highest antioxidative activation was selected; and composite flour was prepared with 0%, 5%, 10%, 15%, and 20% of germinated black quinoa powder to produce the noodles. We evaluated the quality and sensory characteristics of the noodles, including pH, salinity, water absorption rate, volumetric expansion rate, turbidity, chromaticity, extensibility, and texture. With regards to the quality characteristics of noodles with added germinated black quinoa, the pH and salinity decreased with increasing percentage of added germinated black quinoa (p<0.001). Increasing the percentage of added germinated black quinoa resulted in decreased water absorption (p<0.01) and volumetric expansion rates and increased turbidity of the cooked noodles (p<0.001). In terms of the chromaticity, L and b values decreased and a value increased with the increasing percentage of added germinated black quinoa (p<0.001). For the texture, hardness (p<0.001), adhesiveness (p<0.01), springiness (p<0.01), chewiness (p<0.001), gumminess (p<0.001), and cohesiveness (p<0.05) decreased as the percentage of added germinated black quinoa increased; while extensibility (p<0.001) increased. Consumer testing results indicated that the noodles with 15% of added germinated black quinoa showed the best results. Collectively, the evaluation of quality characteristics and consumer acceptability indicated that adding 15% of germinated black quinoa to produce noodles is optimal.

This study uses turbidity and rheological measurements to examine the effects of the molecular weight (MW), substitution type and substitution degree of cellulose ether and water content on the cooking characteristics of rice noodles, the turbidity of the cooking solution, and the compression strength of the cooked noodles. When increasing the MW of cellulose ether and water content, the turbidity decreased, thereby improving the morphological stability of the rice noodles during cooking. Thus, when controlling the above factors effectively, the rice noodle cooking solution had a lower turbidity than with wheat noodles. Measuring the compression strength of the rice noodles using a rheometer was also effective for examining the pasting characteristics of the rice noodles and texture changes during cooking. As a result, the water content and MW of cellulose ether were found to affect the pasting characteristics and texture of the rice noodles more than the other factors examined.

This study was conducted to improve the antioxidative activity of instant noodles containing enzymatic extracts from Ecklonia cava (EEC). EEC has relatively better antioxidative activity than extracts from other indigenous plants in Jeju Island. The EEC (2.5 mg/mL) had 82.5% for the hydroxy radical, 78.4% for the DPPH radical, and 64.9% for the superoxide anion radical scavenging activities, and 65.2% for the cell viability (100 ${\mu}g/mL$). According to the texture of the dough, the DPPH free radical scavenging of uncooked instant noodles, sensory evaluation of cooked instant noodles, and turbidity of the cooking drip, the optimal EEC concentration was 1.8% for the instant noodles. The major amino acids in the instant noodles with EEC were glutamic acid (24.2%), proline (10.2%), valine (10.0%), and isoleucine (12.3%). The zinc and iron in the instant noodles were enhanced by adding 1.5-1.8% EEC. The antioxidant activity of instant noodles with EEC was 75.4% for the hydroxy radical, 74.1% for the DPPH radical, and 51.2 % for the superoxide anion radical scavenging activities.

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.

Several rheological terms were introduced to estimate the properties of cooked noodles with different starch content using tensile tests. Ring-shaped specimens were prepared by connecting both ends of the noodle strip before cooking. Hencky strain and rate, as well as true stress were applied in constant deformation tests. The elastic region on the curves of strain vs. stress was not clearly identified. Strain hardening in the subsequent plastic region was more prominent in low-starch noodles. Elongational viscosities at lower strain rates were used to differentiate noodles with different starch content, representing the dominant effect of protein content in the range of lower strain rates. In stress relaxation tests, the reciprocal of Peleg's constant $K_1$ (initial decay rate) and $K_2$ (asymptotic level) increased and decreased respectively, with an increase in starch content. This indicated that addition of starch contributed to the noodles becoming viscous liquid rather than elastic solid.
