Purpose: This study was conducted to optimize the conditions of manufacturing the wet noodle added with Aloe powder. Methods: The I-optimal design of response surface methodology (RSM) was used for the optimization of added amount of Aloe powder, water content, and kneading time as the independent variables. The quality characteristics (color, texture, water absorption ratio, volume, turbidity) and sensory characteristics (color, flavor, taste, mouth feel, overall acceptance) were analyzed as dependent variables. Results: The lightness, redness, and yellowness of the Aloe noodle were all lowered with the addition of Aloe powder. All texture characteristics such as hardness, elasticity and chewiness of Aloe noodle showed the tendency to increase with increasing amount of Aloe added and kneading time. The water uptake and the volume expansion tended to increase with increasing aloe addition and water addition. As the kneading time increased, the dissolution of solids decreased and the turbidity tended to decrease. Aloe powder content influenced the color, flavor and taste of the noodles most among independent variables, and the mouthfeel of the noodle influenced by the water addition and the kneading time. Conclusion: Aloe noodle showed the best desirability with 3.03% of Aloe powder, 43.56% of water content and 13.06 min of kneading time by RSM analysis. Aloe noodles prepared under these optimized conditions are expected to be able to manufacture and utilize functional Aloe noodles by meeting the content of isobarbaloin, which helps the intestinal functional activity.

Instant noodle is one of the most popular foods in Korea. The objective of this study was to examine the association of instant noodle consumption and food and nutrient intake among children and teenagers in Korea. We used dietary data from 24-h recall of 1,748 subjects aged 7-19 years who participated in the 2005 Korea National Health and Nutrition Examination Survey. Those who consumed instant noodle once or more during the survey period were categorized as "instant noodle consumer (INC)" and were compared for food and nutrient intakes with the others (non-INC). The average age of the INC was 13.4 and that of the non-INC was 12.4; girls consumed more instant noodles than boys (p < 0.05). There was no significant difference in BMI between the two groups. With the exception of grains, as compared to the non-INC, the INC consumed significantly less amounts of potatoes, vegetables, mush-rooms, fruits, spices, seafood, and milk and dairy products. With respect to nutrient intakes, the INC-group showed significantly higher nutrient intakes of energy, fat, carbohydrate, sodium, thiamine, and riboflavin; however, as compared to the non-INC-group, the INC-group showed significantly less intakes of calcium, niacin, and vitamin C. The overall result suggests that consuming instant noodles may lead to excessive intake of fat and sodium, but it may cause an increased intake of thiamine and riboflavin. Therefore, nutrition education that helps children and teenagers choose a balanced meal while consuming instant noodle should be carried out. In addition, manufactures of instant noodles should consider nutritional aspects in product development processes.

The purpose of this study was to understand the influence of instant noodle's selection attribution on satisfaction and to empirically analyze whether or not grade (elementary schoolchildren, middle school students, high school students) plays a moderating role in the relationship between selection attribution and satisfaction. Further, this study examined the differences in demographic characteristics among two groups of subjects divided by instant noodle's selection attribution. Based on a total of 1021 samples, this study verified a total of 3 hypotheses using the SPSS program. Data were analyzed by frequency analysis, chi-square, t-test, factor analysis, reliability analysis, cluster analysis, discriminant analysis, and hierarchical regression analysis. Results of the study were as follows. There were three different instant noodle's selection attributions among the children and adolescents investigated: internal element, external element, and company reliability. The multiple regression results show that internal element (=.391), external element (=.239), and company reliability (=.063) among customers' selection attributions had significant positive effects on satisfaction. In addition, the effect of selection attribution upon satisfaction was partially moderated according to grade. Further, cluster analysis divided subjects into two groups according to instant noodle's selection attribution: high-selection group vs. low-selection group. The wo groups of subjects classified by instant noodle's selection attribution were also different from each other in demographic characteristics. Limitations and future research directions are also discussed.

The noodle making characteristics were investigated for both eleven varities of Korean wheat, such as Chokwangmil, Geurumil, Eunpamil, Tnpdongmil, Woorimil, Oigeurmil, Alchanmil, Cobunmil, Geumgangmil, Seodunmil and Suwon 265, and two varieties of imported wheat, DNS(Dark Northern Spring Wheat) and ASW(Australian Standard White). After cooking of dry-noodle, the elasticities were 0.59-0.79 in the native wheat and 0.55-0.57 in the imported wheat. Among the varieties showing the highest value in the various texture properties of cooked dry-noodle, Alchanmil was highest in gumminess, Geungangmil in cohesiveness, Olgeurumil in adhesiveness, Geurumil in fimmess, Chokwang in chewiness, Tapdongmil in tensile strength Gobunmil in breaking strength. After cooking the wet-noodle, Tapdongmil in elasticity, Geurumil in adhesiveness, Geumgangmil in gumminess, cohesiveness, firmness and chewiness, and Suwon 265 in tensile strength showed the highest values in the respective textural properties. From the sensory evaluation of the cooked dry-noodle, the significant differences (p<0.05) among wheat varieties were observed in color, texture and overall quality. As a result, ASW was excellent in our all qualities of cooked dry-noodle followed by Tapdongmil, Alchanmil and Geumgangmil. The cooked wet-noodle also showed the high sensory scores (p<0.01) were showing the best in Tapdongmil, followed by Eunpamil, Geumgangmil and Woorimil.

To evaluate a possible effects of instant buckwheat noodle on hepatic and serum lipids profiles, apparent digestibilities and growth rate, male young rats were fed diets containing sucrose as a control group, instant 100% wheat flour noodle, or instant wheat noodle fortified with either 10% or 30% buckwheat flour as experimental groups for 4 weeks. Weight gain and feed intake in the two buckwheat noodle fed groups were similar to those of the wheat flour fed groups. In addition, no significant differences were found in the apparent digestibilities among the groups experimented. There were no differences in the hepatic and serum cholesterol levels due to the diets. However, Buckwheat noodle group showed a trend to decrease the liver and serum concentration of triacylglycerol, compared to the sucrose and 100% wheat flour groups. The addition of buckwheat flour to wheat flour up to 30% seemed to be effective in lowering the hepatic triacylglycerol level. After 10hr fasting, the serum glucose level of the buckwheat noodle group was similar to the levels of the other groups. The presented results indicate that instant noodle containing buckwheat at the level of 30% has a mild hypotriglyceridemic effects, and no adverse effects on the digestion of macronutrients in rats.

In an attempt to make dried noodles with composite flours utilizing rice and wheat flours, noodle-making characteristics were improved by the addition of popped rice and wheat flours to rice flour. Their quality was studied in terms of physical properties, noodle-making characteristics, cooking quality test and sensory evaluation. Dried noodle of the composite flour was produced by the conventional method. The results are summerized as follows; 1. In comparing the composite flours, the rice flour containing 30% popped rice flour had a lower maximum viscosity than that with 40% popped rice flour by method of amylograph. The composite flour(20% rice+30% popped rice+50% wheat flour) with added 2% xanthan gum showed the viscosity characteristics which was similar to that of wheat flour. 2. Addition of $1.5{\sim}2.0%$ xanthan gum and $40{\sim}50%$ wheat flour to rice and popped rice flour mixture helped to improve the noodle making properties and the cooking quality, and the noodle making properties and the cooking quality of the mixed flour were almost the same as those of wheat flour alone. 3. The composite flour (rice+popped rice+wheat flour) with xanthan gum showed a higher score in sensory evaluation than that without xanthan gum. The general acceptability scores obtained with the noodle products made of the composite flours with 30% popped rice flour was not significantly different from that of noodle products made of wheat flour alone. However, the noodle products made of the composite flours showed rather higher scores in odor and palatability than the products made of wheat flour alone.

We investigated noodles supplemented with functional ingredients for their antioxidant properties, including total phenol, flavonoid contents, electron donating, nitrite scavenging abilities and ferrous ion chelating effect. The total polyphenol contents of functional noodles arranged in order of decreasing concentration were kudzu (7.98%) > green tea (4.99%) > pumpkin (5.03%) > mulberry leaves (4.99%) > mugwort (4.23%) > cactus (3.57%) > kelp (3.33). The total flavonoid contents in green tea noodles were the highest as 4.35%. The electron donating ability in mugwort noodle was the highest as 12.27% at 1,000 ppm. This amount was 4.85 times than that of wheat flour noodle (2.53%). The nitrite scavenging ability of functional noodles at pH 1.2 arranged in order of decreasing concentration were green tea (66.52%) > cactus (55.12%) > kudzu (52.67%) > pumpkin (50.50%) > mulberry leaves (43.58%) > kelp (41.41%) > mugwort (37.66). The nitrite-scavenging ability of green tea noodle was lower than ascorbic acid (natural antioxidant) 77.83%, while that of green tea noodle was similar with BHT (artificial antioxidant) 69.45%. The ferrous ion chelating effect of noodles containing kelp were the highest as 27.02%. All of the experimental results showed good antioxidant property. Thus, noodles supplemented with mulberry leaves, cactus, mugwort, green tea, pumpkin, kelp or kudzu, demonstrated to have good functional effects for human health.

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.

This study was conducted to determine the usefulness of bamboo leaf powder as a functional ingredient for buckwheat cold noodles. The anti oxidative and fibrinolytic activities of bamboo leaf powder were very high, and were further maintained or improved after strong heat treatment. We prepared buckwheat cold noodles using 0%, 3% or 5% of bamboo leaf powder. Only the cohesiveness of the noodle having 5% bamboo leaf powder was lower than that of the noodles contained 0% and 3% bamboo leaf powder. The L-, a- and b-values were significantly different between noodles which contained bamboo leaf powder and those which did not. Nevertheless, the amount of bamboo leaf powder didn't affect the color parameters of buckwheat cold noodles. According to sensory evaluation, the addition of bamboo leaf powder improved the score of color and texture of buckwheat cold noodles, but overall acceptance was not significantly affected. Cooked volume, cooking loss and turbidity of buckwheat cold noodle containing 5% bamboo leaf powder were lower than the others, indicating that adding 5% bamboo leaf powder prevented the softening of the noodles with moist heat. We concluded that the application of bamboo leaf for the production of buckwheat cold noodle will be a good way to intake the biologically active ingredients for good health.
