Comparative study was performed on noodle characteristics among three domestic wheat varieties (Geurumil, Eunpamil and Alchanmil) and imported one (ASW: Australian Standard White). For the noodle-related characteristics, crude protein, ash and gluten contents were measured, and rheological properties of dough, flour color difference, particle size distribution, cooking properties and sensory properties were evaluated. Crude protein content of Geurumil, Eunpamil and Alchanmil flour were 12.8%, 14.2% and 11.2%, respectively, whereas that of ASW flours was 9.1%. Ash content was the highest in Geurumil (0.56%). The yield of patent flour was the highest in Eunpamil (53.4%) among all the varieties. Higher dough stability with farinogram and maximum viscosity with amylogram were shown in Eunpamil and Alchanmil than those of ASW. The cutting force of cooked noodle from ASW was the lowest maximum, that was measured by texture analyzer. Fairly good color and sensory scores were obtained in cooked noodle of Alchanmil. Studies of noodle-related characteristics indicated that domestic Eunpamil was higher in protein content and flour yield, and Alchanmil was higher dough stability and color, when compared to those of imported ASW. Alchanmil and ASW had good scores in sensory evaluation, especially appearance and color.

Effects of sangwhang mushroom (Phellinus linteus) powder and extract on quality of wet noodle were investigated by adding sangwhang mushroom powder at 2% (w/w: II) of wheat flour and extract at 17 (v/w: III) and 34% (v/w: IV) based on flour source, respectively. Significant decreases were found in L values of dough and noodle, while a and b values increased in proportion to addition of sangwhang mushroom. Addition of sangwhang mushroom decreased volume of cooked noodles, but increased turbidity of soup. Tensions of cooked noodle samples of II, III, IV, and control were 12.17, 17.61, 17.57, and 14.90g, respectively. Sensory properties, including color, flavor, taste, and texture, of noodles added with sangwhang mushroom extracts (III, IV) were significantly superior to control (I) and noodle added with powder (II). These results suggest addition of sangwhang mushroom extract is more suitable than powder for noodle processing.

Quality of noodle processed by addition of hot water extract powder from roasted safflower seed (RSHE) was investigated. Proximate compositions of RSHE was 4.70% of moisture, 32.63% of crude Protein, 6.52% of crude fat, 15.62% of crude ash and 40.53% of carbohydrate. There was no significant difference (p<0.05) in hunter's color value between noodles with and without RSHE. The ‘L’vague of noodle processed by addition of powder from roasted safflower seed (RSP) was very low and significantly different (p<0.05) from other products. With the increase of RSHE addition, the volume and weight of cooked noodles increased (R$^2$=0.9688). The breaking force of dry noodle decreased with the increase of RSHE addition. In the mastication test of cooked noodles, max. weight, strength and hardness increased with the increase of RSHE addition. Dry noodle with 0.3% and 0.5% RSHE recorded high rank, but that with RSP recorded the lowest rank in score of appearance and color by sensory evaluation. The noodle processed with 0.3∼0.5% RSHE showed high sensory quality.

This study was investigated the effects of condensed phosphates (pyrophosphate, metaphosphate and polyphosphate) on the quality and self-life of wet noodle. The initial pasting temperatures were increased by the addition of pyrophosphate and metaphosphate, respectively, whereas those of propylene glycol and polyphosphate were decreased. Pyrophosphate showed the highest final viscosity, whereas metaphosphate showed the lowest. Setback of PG, polyphosphate, pyrophosphate and metaphosphate were all lower than the control. The water absorption ratios of PG and polyphosphate were increased compared to the control, whereas those of pyrophosphate and metaphosphate were decreased. The volume expansion ratios of PG and polyphosphate were slightly increased. Turbidities of PG and polyphosphate were lower than those of the control, whereas those of pyrophosphate and metaphosphate were increased in cooked noodles. The bacterial counts of wet noodles made with PG, polyphosphate, metaphosphate and pyrophosphate were all lower than those of the control after storage at 5$^{\circ}C$.

Freeze-dried Kimchi powder has to be first produced to make Kimchi noodle. Two days, ten days, fifteen days and twenty-five days fermented Kimchi were analyzed respectively to obtain adequate material for freeze-dried Kimchi. Fourteen days' fermented Kimchi with pH 4.0∼4.7 and 0.5∼0.8% acidity was chosen for material for freeze-dried Kimchi, Fourteen days fermented Kimchi was first freeze-dried and powdered. Sensory evaluation was done to decide that 4% addition of the powdered material was optimal. The mixture of Kimchi noodle was analyzed into two perspectives; noodle and Kimchi. The analyzed factors of the mixture was a texture of noodle, color level, Kimchi flavor and its spiciness. The texture of noodle are nutty taste, softness, viscidity and oil flavor. Heavy oil flavor and nutty tasty decreased against the increase of Kimchi powder. Six percent addition of material showed a definite change to the mixture. More than six percent addition destroyed the texture of noodle into near crumbles. Four percent addition of material showed almost same as ordinary noodle texture. Therefore four percent addition of freeze-dried Kimchi was chosen optimal through sensory evaluation.

In an attempt to evaluate the effect of six starch sources-potato starch acetate, corn starch acetate, waxy corn starch, corn starch, potato starch, and wheat starch on properties of frozen noodle, amylograph characteristics of starch-wheat flour composites, cooking quality, maximum cutting force and sensory properties of cooked frozen noodles were examined. Compared with 100% wheat flour as control, potato starch acetate and potato starch-wheat flour composites had slightly lower initial pasting temperature and wheat flour composites with acetylated starches, waxy corn starch and potato starch had slightly higher maximum peak viscosity. At cooking quality examination of noodles made from wheat flour-starch composites, volume and weight of cooked noodles were increased and cook loss was decreased with the addition of acetylated starches and waxy corn starch. Maximum cutting forces of cooked frozen noodles containing more than 15% of potato starch acetate and only 15% of corn starch acetate were higher than that of control. Other starches except potato starch improved sensory properties of cooked frozen noodles and the greatest positive effect was acetated potato starch.

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.

Korean dried noodles were prepared from 6 different types of Australian wheats and tested for their cooking property and sensory quality. The flours from different wheat types were characterized by the fractionation of starch and gluten. The flow property of fractionated starch and flour suspensions were determined. The protein content of flour influenced many aspects of dried noodle quality. The Cooking rate decreased as the protein content increased. The higher protein content resulted in the higher of shear extrusion force, and lower grade of appearence of cooked noodle. The flours containing about 10% protein, i.e. Australian standard White flours, were appeared to be most adequate to make Korean dried noodle.

The in vitro digestive properties of 6 domestic noodle products (spaghetti, somyeon, ramyeon, dangmyeon, naengmyeon, and jjolmyeon) were compared after cooking under the manufacture's recommended cooking conditions. The kinetic constant (k), representing the rate of hydrolysis at the initial digestion stage, was highest in the somyeon noodles (0.1151), followed by naengmyeon (0.0954), and was lowest in the spaghetti (0.0421). However, the concentration of starch ($C_{\infty}$) hydrolyzed over 2 hr was not different between the spaghetti (96.22) and the somyeon (96.40), indicating that different digestion behaviors occurred in each type of noodle, even though the amounts of digested starch were similar. The ramyeon, dangmyeon, and naengmyeon noodles showed relatively lower $C_{\infty}$ values than the spaghetti and the somyeon noodles. The spaghetti had the highest amount of slowly digestible starch (SDS, 43%) and the lowest glycemic index (GI, 87.8), whereas the somyeon had the lowest SDS value (9.6%) and the highest or (93.0). The digestibility differences among the noodles were attributed to differences in their flour compositions and manufacturing processes.

The principal objective of this study was to evaluate quality characteristics of dried noodles when different concentrations of lotus leaf powder (LLP) were added to the wheat flour, thereby determining which noodle recipe was preferred. The cooking quality, mechanical texture properties, and viscosity were measured, and then a sensory evaluation was conducted with the prepared noodles. The gelatinization points of the composite LLP-wheat flours were shown to have an increased, viscosity at $95^{\circ}C$ after 15 minutes. As measured via amylograph, the maximum viscosity values of those samples were decreased as the LLP content was increased. As well, when increased amounts of LLP were added, both the L and a values were reduced, whereas the b value was increased. The color values, weight and volume of the cooked noodle increased, as did the turbidity of the soup. With regard to the textural characteristics, the LLP additive increased hardness and cohesiveness, and reduced adhesiveness and springiness. Overall, according to the results of our sensory evaluation, the noodles prepared with 5% LLP were preferred over the other noodles.
