  • This study was conducted to evaluate quality characteristics of noodles when different concentrations of chlorella extract powder were added to the wheat flour. The characteristics of noodle including cooking properties, color, mechanical texture properties, and sensory properties were determined. The noodles containing chlorella extract powder exhibited higher values in cooked weight, volume, moisture absorption, and cooking loss. When the amount of chlorella extract powder increased, the Hunter L(lightness) value, a(redness) value of cooked noodles decreased but b(yellowness) value increased. From the textural properties measured by texture analyzer, the noodles with chlorella extract powder were significantly lower in hardness, cohesiveness, springiness, gumminess, and chewiness than those of 100% wheat noodle. The results of sensory evaluation of cooked noodles containing chlorella extract powder indicated that the cooked noodle with 1.5% chlorella extract powder showed the highest value. Based on cooking properties and sensory evaluation, chlorella extract powder up to 1.5% could be substituted for wheat flour to improve the noodle quality.

  • This study compared the texture characteristics and consumer acceptance of cooked wheat noodles produced in four countries, which were Korea, Japan, China, and Italy. Noodle types were selected after FGI (focus group interview). Eleven noodles were studied, and they were categorized into four types: udon, fried udon, oriental noodles of various thickness, and pasta. Color was measured as L (lightness), a (redness), and b (yellowness) values using a colorimeter. Lightness decreased when noodles were cooked, whereas redness and yellowness of cooked noodles were unchanged. Texture properties of wheat noodles in terms of hardness, springiness, cohesiveness, and chewiness were measured using the Rheometer. Italian spaghetti (spgt_IL), Korean fried udon (yk_udng_KR) had highest values for hardness. Korean udon had the highest value for springiness, whereas Chinese medium noodle (mid_CN) had the lowest value (p<0.05). Chinese thick noodle (thick_CN) and fettuccine (fettc_IL) showed lower hardness but higher springiness. Cohesiveness was significantly higher for Japanese udon (udng_JP), Chinese medium noodle (mid_CN), and Chinese thick noodle (thick_CN), whereas values for Korean thin noodle (thin_KR) and Korean fried noodle (yk_udng_KR) were significantly low (p<0.05). Spaghetti (spgt_IL) showed significantly high values for chewiness (p<0.05). For overall acceptability, thick Korean noodle showed the highest score with a level of 'slightly like'. Taste and texture attributes were highest among all noodles, and its high scores for chewiness and smoothness might contribute to its overall acceptance. Korean thick noodle, Korean udon, and Japanese udon were not significantly different from Korean or Japanese thin noodles. Japanese fried noodle (yk_udng_JP) showed the lowest acceptance among noodles in terms of color, flavor, taste, and texture. Chinese thick and medium noodles showed lower scores for overall acceptability, whereas chewiness was not significantly different from other noodles. Spaghetti and fettuccine showed lower scores in terms of overall acceptability, taste, texture, springiness, and chewiness.

  • Wet noodles with different percentages of amaranth powder were prepared and their cooking characteristics were evaluated. The cooking quality, mechanical textural properties, and a sensory evaluation was conducted with the prepared noodles. Cooked noodle properties, weight, and volume decreased as amaranth content of the wheat flour increased, whereas turbidity and water absorption of the soup increased, except for cooked noodles with 30% amaranth. The L-value of the raw and cooked noodles decreased significantly with increasing amaranth powder content. The a- and b-values increased with increasing amounts of added amaranth powder. The L-value of the raw and cooked noodles with amaranth was significantly lower than that of the control, and the a-value was lower than that of the control, whereas the b-value was higher than that of the control for both raw and cooked noodles. A texture profile analysis of the raw noodles showed significantly higher levels of hardness, cohesiveness, gumminess, chewiness, and springiness in the amaranth noodles compared to those in the control; the values for adhesiveness were not significantly different. The hardness, gumminess, springiness, and chewiness of the cooked noodles decreased in proportion to the quantity of added amaranth. The springiness, adhesiveness, and cohesiveness of cooked noodles with amaranth decreased slightly. Overall, the results of a sensory evaluation revealed that the cooked noodles with amaranth had higher values than those of the control, except for overall acceptability. Amaranth added at a concentration of up to 30% increased brown color and the peculiar amaranth odor. In a sensory evaluation, cooked noodles with 20% amaranth powder were preferred more than the other noodles for overall acceptability.

  • Protein characteristics of Korean wheat were evaluated to determine the effects of protein content and quality on processing and textural properties of white salted noodles compared to US wheat flours with various wheat classes and commercial flours for making noodles. Protein quality parameters, which were independent of protein content and included SDS sedimentation volume with constant protein weight, mixograph mixing time and proportion of 50% 1-propanol insoluble protein, of Korean wheat flours with 2.2+12 subunits in high molecular weight glutenin subunit compositions were comparable to those of commercial flours for making noodles. Parameters related to noodle making, including optimum water absorption, thickness and color of noodle dough sheet, correlated with protein content and related parameters, including SDS sedimentation volume with constant flour weight, mixograph water absorption and gluten yield. No significant relationship was found in protein parameters independent of protein content. Hardness of cooked noodles from Korean wheats was lower than that of US wheat flours compared to similar protein content of commercial noodle flours. Adhesiveness, springiness and cohesiveness of cooked noodles from Korean wheats were similar to US wheat flours. Hardness of cooked noodles correlated with protein content and related parameters.

  • This study was to investigate the quality characteristics of noodles prepared with germinated brown rice and rice bran, and to determine the changes in GABA content and antioxidant activity of the noodles. These noodles were evaluated for cooking properties (cooking loss, swelling index, water holding capacity), total polyphenols, antioxidant activities (radical scavenging of ABTS and DPPH), and GABA contents. The addition of germinated rice bran in the range of 5, 10, and 15% showed a significant influence on cooking loss, although no effect on swelling index was observed. The raw and cooked noodles containing germinated brown rice and rice bran contained more GABA contents (2751.6~4176.7 and 5522.0~9617.8 nmol/20 g of fresh noodle, respectively) than those of non-germinated brown rice and rice bran. Noodles made with germinated brown rice and rice bran had similar total polyphenolics contents and antioxidant activities compared to noodles made with non-germinated brown rice and rice bran. Overall, the germinated brown rice could be used as a good ingredient to increase the nutritional value and antioxidant properties of wheat flour noodle without affecting the cooking properties.

  • The purpose of this study was to investigate the quality characteristics and antioxidant activities of noodles added with red lentil powder (RLP). Noodles were prepared by addition of 0, 15, 30, and 45% powder to flour of the basic formulation. RLP noodles were evaluated for their cooking properties (weight, water absorption, volume, and turbidity), color values, texture characteristics, sensory characteristics, and antioxidant activities. The weight, water absorption, and volume of cooked RLP noodles increased according to RLP content. The turbidity values of cooking water increased according to RLP content. The L value of RLP noodles decreased with increasing amounts of RLP, whereas a and b values increased with increasing amounts of RLP. The texture characteristics of RLP noodles decreased compared to those of control noodles except for adhesiveness. Antioxidative activities of RLP noodles significantly increased with increasing RLP content (P<0.05). The sensory preference test revealed that RLP 30% noodles showed the highest scores for smell, taste, chewiness, and overall preferences. It is suggested that RLP 30% noodles could be substituted for wheat flour to improve noodle quality.

  • This study was performed to provide basic data that will predict the usefulness of buckwheat sprout as food materials. The quality characteristics of noodles prepared with buckwheat sprout powder were investigated The buckwheat sprout powder was added to the noodles in 0, 2, 4, 6, and $8\%$ in proportion to the weight of wheat flour, respectively. The added amounts of buckwheat sprout powder did not affect the volume of the noodles. The weight of noodles was decreased, whereas tumidity of the soup after cooking the noodles was increased with the increment of the amount of added buckwheat sprout powder. The color of powder mixture, wet noodles, and cooked noodles was changed by the addition of buckwheat sprout powder. Lightness(L) was decreased, whereas yellowness(b) and redness(a) increased as the amount of buckwheat sprout powder increased. In the texture analysis, hardness and chewiness of wet noodles were increased significantly by the addition of buckwheat sprout powder. Hardness, chewiness, and gumminess increased significantly in the cooked noodles with more than $6\%$ substitution of buckwheat sprout powder. Other textural properties did not show any significant changes. The results of sensory evaluation revealed that the overall preference of noodles with 2 to $4\%$ substitution of buckwheat sprout powder was better than other sample groups. Therefore, the appropriate amount of addition for the buckwheat sprout noodles was 2 to $4\%$ buckwheat sprout powder in proportion to the weight of wheat flour.

  • 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.

  • Cysteine, a thiol group-containing reducing agent which is known to relax the strain and increase the viscosity of dough, was added to Korean and imported wheat flour noodles to investigate the effect on the properties of raw, dried, and cooked noodles and to determine the optimum cooking time and amount to improve the color of noodles. Addition of cysteine up to 1% of flour (8.25 mmole/100 g flour) was not effective in increasing the brightness of raw and dried noodles and in changing the water activity of dried noodle. However, cysteine improved the brightness of cooked noodle made of both Korean and imported wheat flours. Also, there were notable differences in cooking and sensory properties of cysteine-added cooked noodles such as less firm and stickier texture due to the extraction of organic compounds into broth. When the noodles were cooked for their optimum cooking time, no difference was noticed in the texture and overall preference regardless of the addition of cysteine. Overall, the addition of 1 % cysteine increased the brightness of cooked noodles and reduced the cooking time.

  • In this study, the antioxidant activities and quality characteristics of noodles amended with spirulina were evaluated. Wheat flour noodles were prepared using three levels of spirulina (0, 0.63, 1.25 and 2.5%). The moisture content of the noodles that contained spirulina was higher before and after cooking. and these increases occurred in a concentration dependant manner. Furthermore the Hunter L (lightness), a (redness) and b (yellowness) values of noodles that contained spirulina were higher before and after cooking. and these values increased as the concentration of spirulina increased. Moreover the textural properties, which included, hardness, cohesiveness, springiness, gumminess, and chewiness, were significantly higher in noodles that contained than in the controls. Additionally, the antioxidant activity of noodles that contained spirulina increased in a concentration dependent manner. Specifically, the: $IC_{50}$ values of the DPPH radical scavenging activity for raw noodle was 726.00 mg/g, whereas that of raw noodles that contained 1.25 and 2.5% spirulina was 449.96 mg/g and 439.44 mg/g, respectively. Finally, a sensory preference test revealed that cooked noodles that contained 1.25% spirulina had the highest color, odor, taste and overall preference scores. Taken together, these findings suggest that up to 1.25% of the wheat flour could be substituted with spirulina to improve the quality of the noodles.
