  • 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 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.

  • This study was performed to find out the quality characteristics of rice noodles by addition of red ginseng(0, 2, 6, 10%). The quality characteristics of the sample were estimated in terms of general composition, growth of microorganism and sensory evaluation. The results from this study were as follows. The protein, lipid and ash contents did not show significant difference in any of the groups. In dry rice noodles, moisture content significantly decreased in red ginseng groups but, in half-cooked rice noodles, moisture content significantly increased in 6 % and 10% red ginseng added groups(p<0.05). The microbial count showed less growth in red ginseng added groups after 3 months(p<0.05). According to sensory evaluation, surface color proved very good in the 10% red ginseng added group among the training panel while very good in the 2% red ginseng added group among consumers. Flavor was good in red ginseng added groups(p<0.05). Taste was very good in the 3% red ginseng added group. Appearance and overall quality were highest in the 2% and 6% red ginseng added groups(p<0.05). Therefore, rice noodles containing 2% or 6% red ginseng were most preferable and safe during 5 months and 6 days in dry and half-cooked noodles respectively.

  • A study was conducted to investigate the effects of rice bran dietary fiber on wheat flour rheology and wet noodle quality. More than 99% of rice bran dietary fiber contained smaller particle size than $250\;{\mu}m$. The initial pasting temperature, peak and final viscosities in amylograph, and the water absorption and dough stability in farinograph increased with the increase of rice bran dietary fiber concentration. The lightness values decreased with the increase of rice bran dietary fiber concentration in raw noodles as well as cooked noodles. The addition of rice bran dietary fiber was not effective on the cooked weight and volume of cooked noodles. However, the cooking loss of cooked noodles was the highest in control, and increased with the increase of rice bran dietary fiber concentration. Most of texture parameters (hardness, adhesiveness, gumminess and chewiness) of cooked noodles increased, but the cohesiveness decreased with the increase of rice bran dietary fiber concentration. There were no significant differences in appearance, taste and acceptability of cooked noodles between control and noodles containing 3% and 6% rice bran dietary fiber.

  • Rice noodles are popular worldwide; however, no standard procedure is available for screening the potential for rice flour to make good quality noodles. This study reports two standard laboratory-scale procedures for preparing flat (sheet type) and extruded noodles. Eight rice cultivars were examined and the cooking loss and tensile strength of cooked noodles were determined. It was relatively easy to control the amount of water added to extruded noodles, whereas flat noodles were very sensitive to the amount of water used. Sheet formation was determined based on the amount of moisture content during preparation, and the Chenmaai cultivar was found to be most appropriate for both noodles making procedures and cooking and textural properties. Finally, good noodle making cultivar such as Chenmaai was less likely to be affected by the milling method.

  • The influence of heat-moisture treatment (HMT) and substitution of rice flour containing different amylose contents on the quality characteristics of rice noodles was investigated. HMT was applied to rice flours with 21% moisture content at 100 and 105$^{\circ}C$ for 30 min. Three rice cultivars were used, including high amylose of Goami (GM) and intermediate amylose of Choochung (CC) as domestic rice flours and imported rice of Taeguk (TG) as a control. HMT and substitution of rice flour with different amylose contents affected the cooking and texture quality of rice noodles. When rice noodles were made of intermediate amylose rice flour with HMT, cooking properties improved with decreased cooking loss and cooking water turbidity and thus were closer to those of control. Especially, the hardness, adhesiveness, tensile strength, and darkness of rice noodles notably increased when HMT rice flour was used. Based on the results of quantitative descriptive analysis for selected rice noodles, the noodles made of HMT CC at 105$^{\circ}C$ (CC105) had high scores for resilience and adhesiveness and low scores for hardness compared with imported commercial rice noodles and other experimental noodles such as TG, HMT GM100, TG+CC, and TG+CC105. In conclusion, rice noodles were made of composite flours containing high amylose and intermediate amylose contents or HMT intermediate amylose content rice flour.
