The viscoelastic behavior of traditional Korean noodles was examined by using a tensile tester built in the laboratory. The creep test of cooked noodle strand showed that a linear viscoelastic response could be expected for a short time of creep, i.e. 120 sec for wheat flour noodle and 60 sec for wheat-sweet potato starch noodle, with the stress range between $4{\times}10^4\;and\;14{\times}10^4\;dyn\;cm^{-2}$. The elastic modulus was estimated to be $7.0{\times}10^5\;dyn\;cm^{-2}$ for wheat flour noodle and $3.9{\times}10^5\;dyn\;cm^{-2}$ for wheat-sweet potato starch noodle. A peculiar increase in viscosity with increasing stress, i.e. stress-hardening, was observed in the noodles studied.

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.

The objectives of this study were to reduce the characteristic dark color of Korean wheat flour noodles. Several additives were tested to reduce dark color of wheat flour dough and 2% ascorbic acid and 0.05% cysteine were selected as additives to Korean wheat flour noodle. Comparative study was performed between commercial imported wheat flour noodle and Korean wheat noodle with two additives to investigate the color, mechanical and sensory properties of noodles. Addition of 2% ascorbic acid increased the brightness of raw and dried Korean wheat flour noodles and 0.05% cysteine was the most effective in improving the brightness for cooked wheat flour noodles. Mechanical properties of cooked Korean wheat flour noodles with 2% ascorbic acid and 0.05% cysteine were similar to that of the imported wheat flour noodles. However, sensory evaluation test showed Korean wheat flour noodles with 2% ascorbic acid had the darkest yellowish-red color, the strongest aftertaste and the lowest overall quality. Therefore, the addition of cysteine was the most effective in mechanical and sensory attributes as well as discoloration of cooked wheat flour noodles.

The changes in the mechanical model parameters during cooking and subsequent storage, were related to the sensory quality of the noodles. The sensory hardness and chewiness were tested by Milestone method and the overall preference was evaluated by hedonic scale test. Hardness was affected primarily by increasing cooking time and in lesser degree by storage time after cooking. Chewiness was diminished by increasing cooking time and subsequent storage. The preference of wheat flour noodle was not significantly affected by cooking time, while that of wheat·sweet potato starch noodle decreased significantly by excess cooking time. Instantaneous elasticity represented the softness of noodle. The elastic components and viscosity components had significant relationship with the sensory quality of wheat noodle. On the other hand the retardation time was important for the sensory quality of wheat-sweet potato starch noodle.

The principal objective of this study was to assess the quality properties of noodles to which browned oak mushroom (Lentinus edodes) paste was added at concentrations of 10%, 20%, and 30% to wheat flour, respectively. With regard to the cooking properties of the noodles, the weight and water absorption of the cooked noodles increased with increasing paste contents, but the turbidity of the noodle soups decreased (p<0.05). The hardness and gumminess of the uncooked and cooked noodles decreased significantly in proportion to the quantity of added paste, except in the case of the cooked noodles with 30% paste. The springiness and cohesiveness of both noodles with Lentinus edodes paste were significantly higher than in the controls. The lightness of the uncooked and cooked noodles decreased in accordance with the amount of added paste. However, the yellowness of both noodles was significantly increased. Moreover, the results of our sensory evaluation showed that the cooked noodles with 20% and 30% added Lentinus edodes paste had higher values. Thus, Lentinus edodes paste added to a concentration of up to 30% was shown to effectively improve the quality of noodles.

This study investigated the quality characteristics of instant rice noodles manufactured with broken rice flour as an application of rice-processed products. We examined the physicochemical characteristics of common rice flour (CRF), broken rice flour (BRF), and CRF mixed with BRF (CBRF). Futhermore, instant rice noodles were manufactured with these three types of rice flour, and their quality and sensory characteristics were also investigated. Damaged starch content and water-binding capacity of rice flour were highest in BRF. Particle size of rice flour was significantly different among the three types. RVA pasting viscosities of BRF and CBRF were higher than that of CRF. Volume after cooking of instant rice noodles increased in rice noodles made with broken rice flour (BRN). Turbidity and cooking loss of BRN were higher than those of common rice noodles (CON). For texture properties, CON displayed the highest hardness, adhesiveness, and chewiness. In the sensory evaluation, springiness and overall acceptability values of CON were significantly higher than those of other rice noodle types (BRN and CBRN). In conclusion, BRN showed increased cooking loss and turbidity with reduced texture and overall acceptability values. The results of this study suggest that added amount of CRF may significantly increase the overall quality of instant rice noodles prepared with BRF.
