This study evaluated the quality characteristics of semi-dried noodles prepared with various dry rice flours (0, 25, 50, 75, and 100%) in order to develop the most preferred noodle recipe and to increase rice consumption. Amylography measured the viscosity of composite dry rice flour-wheat flour and indicated that the gelatinization point and maximum viscosity decreased as the level of dry rice flour increased. Both L and a values for cooked noodle significantly increased as the dry rice flour increased; however the L value decreased for uncooked of noodles. Weight, volume and water absorption of cooked semi-dried noodles significantly decreased as the dry rice flour increased; however the turbidity of soup increased. Texture properties such as hardness, springiness, cohesiveness, and adhesiveness decreased as the level of dry rice flour increased. As the amount of rice flour added increased, large particles of gluten were reduced while smaller particles of starch increased by scanning electron microscopy (SEM). The color, taste, and overall preference of 75% noodles were the highest in the sensory characteristics. The results, showed that the addition of dry rice flour positively affects the overall sensory characteristics of semi-dried noodle with 75% representing the optimal level for addition.

To promote the consumption of race, comparative study was performed on characteristics of wheat flour noodle mixed with brown rice flour and colored rice flour. Protein content of colored rice was higher than that of the brown rice, but lipid and ash contents were similar to those of brown rice. Colored rice flour had significantly lower peak viscosity, holding viscosity, breakdown viscosity, final viscosity and setback viscosity than those of wheat flour, while brown rice had significantly higher peak viscosity, breakdown viscosity and setback viscosity than those of colored rice flour and wheat flour. Colored rice and brown rice had 5.3~6.4% total dietary fiber, and the proportions of soluble fiber in total dietary fiber were quite low, ranging from 9.4% to 18.8%. L(brightness), a(redness) and b(yellowness) of raw noodles were measured using a colorimeter. L(brightness) and b(yellowness) values of Asian raw noodles made from colored rice and brown rice significantly decreased. Addition of colored rice flour and brown rice flour to Asian noodle reduces cutting forces of dry and cooked noodles. The cooked noodle with 10% chalheukmi waxy rice flour was the highest in the cutting force of cooked noodle. Addition of 20% chalheukini waxy rice flour and 20% brown rice flour to wheat flour was got to a relatively high score for appearance, color, texture, taste and overall eating quality from sensory evaluation of cooked noodles.

To address the limitations of manufacturing noodle products using rice, brown rice noodles were created by the fermentation of brown rice containing several nutrients and the quality of these noodles were evaluated. White rice noodles, fermented white rice noodles, brown rice noodles, and fermented brown rice noodles were developed using white rice and brown rice, respectively. We found that the content of crude proteins present in the noodles during the fermentation process increased and the content of crude fat and carbohydrates in the noodles was reduced. In addition, the water content of brown rice noodles was twofold higher than that of white rice, although under fermentation conditions, the water content of brown rice noodles decreased slightly. A slight change of chromaticity was observed during the fermentation process. In cooking, the weight and volume of the noodles increased, with the change being lowest in noodles based on white rice. White rice-based noodles exhibited significantly higher turbidity in the cooked noodle soup, while other noodle products showed relatively constant turbidity. Most of the products showed a decreased texture, becoming soft with cooking; however, the elasticity of the cooked products increased. Our results suggest that the disadvantages of producing rice noodles can be overcome by the development of fermented brown rice noodles containing a variety of nutritional components. This would potentially develop a market for rice-based manufactured foods that appeal to modern preferences.

The effect of treatments with alcohol, chitosan, or with both alcohol and chitosan for extending the shelf-life of Korean white rice cake and wet noodle was investigated by measuring quality changes such as total microbial count, pH, and sensory qualities. Total microbial counts for control, alcohol-treated, and 1% lactic acid-treated white rice cakes exceeded the initial putrefactive criterion level of $1{\times}10^{6}\;CFU/g$ at 6, 27 and 20 days of storage, respectively. However, total microbial count of the white rice cake treated with chitosan was still less than the criterion level even at 76 days of storage. In the case of wet noodle, total microbial counts of control and alcohol-treated groups exceeded the criterion level within 7 days of storage, while that of chitosan-treated group was far less than the criterion level even at the end of storage of 82 days. Chitosan treatment extended the shelf-lives of both white rice cake and wet noodle appreciably.

The purpose of this study was to investigate the effects of the addition of various amounts (0, 1, 3, 5%) of Mokdanpi(P. suffruticosa) powder on the shelf life and the physicochemical, sensory characteristics of rice cakes and noodles to examine the possibility of using Mokdanpi as a natural food preservative for food products. The decrease in the moisture content of rice cake and noodle samples during storage was much less in Mokdanpi-added groups than the control group. The color L value increased and a and b values decreased in the rice cake samples, and color L value, b value decreased and a value increased in the noodle samples during storage. The microbial growth was less in Mokdanpi-added groups than the control group. In sensory evaluation, there were no significant differences among the control and 1, 3%-added groups in terms of color, flavor, taste, moistness, cohesiveness and overall quality; however, 5%-added groups received significantly less score than others (p＜0.05). As the storage time increased, the sensory scores decreased significantly in the control and 1 %-added groups of both rice cakes and noodles (p＜0.05), but no changes were observed in 3, 5%-added samples. The results suggested that Mokdanpi is effective in increasing the shelf life and inhibiting the staling of rice cakes and noodles.

Objectives: With the increasing number of single households and so-called Honbab-jok, those who eat alone, people tend to enjoy convenient and simple meals, such as single dish meals. This study was performed to provide data on the energy and nutrient content, and nutritional adequacy of single-dish meal. Methods: From the literature reviews, 61 types of single-dish meals were selected, and divided into 4 groups (steamed rice, noodle, porridge, and sandwich burger), and a further 11 sub-groups (bibimbab, fried rice, topped rice, rolled rice/ warm noodle, cold noodle, seasoned noodle, dukgook/ porridge/, and sandwich, burger). In addition, 382 junior high school students from Gyeonggi, Sejong, Jeonbuk, and Chungnam areas were recruited for the survey. The survey questionnaires were composed of the characteristics, preference, and intake frequency of single-dish meals. The representative energy content (arithmetic mean) of single-dish meals were calculated, and compared with the energy contents of preference and intake frequency-weighted values adjusted. The representative nutrient contents, energy contribution ratio, and INQ (index of nutritional quality) of a single-dish meal were calculated for a nutritional adequacy evaluation. Results: The study subjects considered a single-dish meal as tasty, simple and fast to prepare, inexpensive, nutritious, and no low calorie food. The preference scores of all but 1 sub-group of singledish meals were ${\geq}5.00$ (5.00~5.97), and 1 sub-group (porridge) was 4.67 on a 7-point scale. The intake frequency of 11 sub-groups were 0.31~1.71/week, porridge was the lowest at 0.31 and warm noodles was the highest at 1.71. Fried rice, rolled rice, and warm noodle' intake frequency were ${\geq}1/week$. The representative energy of steamed rice, noodle, sandwich burger were 443, 429, and 428 kcal, respectively, and that of porridge was 264 kcal. Less than 5% differences in the representative energy of 4 groups were observed when adjusted for the preference or intake frequency-weighted values. The energy contribution ratio of macro-nutrients calculations showed that porridge was a high carbohydrate and low fat food, whereas sandwich burger were high fat and low carbohydrate foods. The INQ of calcium and vitamin C were less than 1.0 in all 4 food groups, but the INQ of protein and thiamin were > 1.0 in all 4 single-dish food groups. Conclusions: The representative energy in the 4 groups of single-dish meal was 264~450 kcal, which is a rather low calorie meal, and the energy contribution ratio of macro-nutrients were inadequate. The protein and thiamin levels were sufficient but the calcium and vitamin C levels were insufficient in all 4 groups of a single-dish meal judged by the INQ. The additional intake of fruits and milk dairy products between meals with a single-dish meal, supply of calcium and vitamin C may increase, which will result in an improved nutritional balance.

We investigated the quality characteristics of rice noodles supplemented with turmeric, purple sweet potato, or seaweed (Hizikia fusiforme). RVA (Rapid Visco Analyser), color, water activity, texture, and cooking properties were tested. Initial gelatinization temperature of noodles containing turmeric were the highest. Peak viscosity, holding strength, break down, final viscosity, and set back of noodles containing purple sweet potato were highest, indicating that the gelatinization state was more unstable and retrogradation would occur faster. The L value of the seaweed noodle was the lowest, while the a and b value of the turmeric noodles were $7.3{\pm}0.3$ and $40.2{\pm}1.3$ respectively, higher values than turmeric and seaweed noodles. Water activity of the seaweed noodle was 0.665, higher than turmeric and purple sweet potato noodles. Cooking properties (including weight, volume, and water absorption) and turbidity of seaweed noodles showed the highest growth rate. In terms of texture, the hardness was highest in purple sweet potato noodles, and the cohesiveness and gumminess was highest in seaweed noodles. The quality characteristics of rice noodles supplemented with turmeric, purple sweet potato, or seaweed showed that seaweed noodles were stable in gelatinization and cooking properties.
