This study was conducted to optimize processing of functional seasoning sauce for instant noodles (SSIN) using response surface methodology (RSM), and to compare the functional properties of commercial SSIN. Central composite designs were adopted in the SSIN processing for ingredient formula optimization. Concentrations of sea tangle ($X_1$), traditional soy sauce ($X_2$), yeast extract ($X_3$) and Ecklonia cava extract (ECE) ($X_4$) were chosen as independent variables. The dependent variables were glutamic acid content ($Y_1$), score of sensory evaluation ($Y_2$), and antioxidative activity ($Y_3$). We found the optimal conditions to be $X_1$=3.91%, $X_2$=20.57%, $X_3$=3.04% and $X_4$=3.78%. The predicted values of the multiple response optimal conditions were $Y_1$=124.0 mg/100 g, $Y_2$=7.6 and $Y_3$=1.95. The antioxidative activity (PF, PF=oil induction period with sauce/oil induction period with distilled water) and ACE inhibitory activity of ECE-added SSIN were 1.98 and 29.0%, respectively, which were significantly higher than those of commercial SSIN (1.09 and 4.4%, respectively).

Sweet pumpkin is a squash fruit that contains low total solids but is rich in carotene, pectin, mineral salts, vitamins, and other substances beneficial to health. An attempt was made to develop a value-added food product; sweet pumpkin powders (SPP) were incorporated into a model system of noodles as a healthy food ingredient, and selected physicochemical properties and consumer preferences were determined. Elevated SPP concentration was associated with increased pH, soluble solids, and turbidity; however, moisture absorption decreased (P<0.05). Increasing amounts of SPP significantly reduced both raw and cooked noodle brightness (L*); however, yellowness (b*) appeared to increase. In addition, 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity increased significantly (P<0.05). The consumer acceptance test indicated that incorporation of 10% SPP to the formulation is recommended to take advantage of the health benefits of SPP without major sacrificing the quality acceptance of consumers.

The effects of barnyard millet (Echinochloa spp.) content (10~30%) on wheat flour dough and noodle properties were investigated. As the amount of barnyard millet increased, the particle size and ash content of mixed flour increased, while lightness tended to decrease. The gelatinization characteristics of millet flour showed higher peak viscosity, holding strength, final viscosity, and setback compared with wheat flour. There was significant positive correlation between protein content and sedimentation volume, as well as between protein content and water absorption. As the amount of barnyard millet increased, hardness, springiness and cohesiveness of wet noodles tended to decrease. From the results of sensory evaluation, composite flours (addition up to 20% barnyard millet) were rated with a quality score for taste and overall acceptance which was comparable with the control flour.

In order to manufacture the high-quality products as well as to promote their consumption, dry noodles were prepared with Korean wheat flour and brown glutinous rice flour with and without aroma and quality characteristics of dry noodles were investigated. The average particle size distributions of aromatic brown glutinous rice flour and brown glutinous rice flour ranged from 12.38 to $15.59\;{\mu}m$, which was different from that of control. As a result of farinograph study, water absorption of dough increased and decreased with increasing amounts of brown glutinous rice flour with and without aroma, respectively. Stability, developing time and elasticity of dough showed a decreasing tendency. When compared with the control, aromatic brown glutinous rice samples produced noodles with a greater degree of lightness and a less intensity of yellowing. Replacement of up to 20% of Korean wheat flour by aromatic brown glutinous rice flour and brown glutinous rice flour in noodle had similar cooked properties such as weight gain, volume and water absorption as compared with the control. From the result of sensory evaluation, composite flours(addition up to 30% aromatic brown glutinous rice flour and up to 20% brown glutinous rice flour) and control were rated with a relatively high quality score for appearance, taste and overall eating quality.

Small black beans (SBB) were germinated up to 72 h at 23$^{\circ}C$, and 48 h germinated SBBs having the highest isoflavone content were chosen for noodle preparation. Some of the germinated SBB were treated by 20 min boiling (B) but some were not boiled (NB). For noodles, the germinated SBB flour replaced 15% or 20% of wheat flour, so five kinds of noodles were prepared and tested: control, 15B, 15NB, 20B, and 20NB. Higher amount of bean flour resulted in significant decrease of $L^*$ and increase of $b^*$ values in noodle. After 20 min cooking, the noodles containing germinated SBB flour showed less soluble sugar content in cooked water than control, and the lowest value was observed in 15B. For textural properties, the addition of SBB flour lowered hardness and adhesiveness of noodle, but increased chewiness than control. In sensory tests, the most acceptable sample was 15B because of developed texture and better appearance which seem to be good for health.

This study evaluated the quality characteristics of dried noodles made of wheat flour supplemented with different concentrations of skate powder. Cooking quality, mechanical texture properties, gelatinization temperature and viscosity were measured, after which sensory evaluation was performed with prepared noodles. Water binding capacity, solubility and swelling power of the composite skate powder and wheat flours were higher than those of pure wheat flour. Gelatinization temperature of the composite skate powder and wheat flours increased, while initial, interim, and maximum-viscosity at $95^{\circ}C$, decreased, with increasing skate powder content. In relation to color values, increasing skate flour content led to decrease in L and b values and increase in a value. For the textural characteristics, the addition of skate powder increased hardness, springiness, chewiness and adhesiveness. Overall, noodles made with 3% skate powder were preferred compared to other samples.

This study was evaluated mass production processes for flour noodles containing perilla leaf (FNPL) and to examine the antioxidant properties of FNPL. The processes for perilla leaf preparation before dough making were the main focus. The sensory evaluation was used as a tool to determine the optimal conditions for each step in the process. The appearance, taste, flavor, texture and overall acceptability were evaluated using a 9 point scale sensory evaluation. Eight minutes blanching of perilla leaf in boiling water (1:30, w/v) was found to be a suitable time to remove the unpleasant leaf flavor remaining in the final noodle product when fresh perilla leaf was used. The appearance, taste, texture and overall acceptability of FNPL were significantly different from FNPLs prepared with other blanching times. The appearance of FNPL containing 40% (w/v) perilla leaf homogenates was the best. In the dough making process, additional water was not required when 6 portions of 40% perilla leaf homogenate were added to 10 portions of flour, suggesting that the water adding step in the dough preparation process can be skipped. The antioxidant activity of FNPL was expressed as the radical scavenging activity. The DPPH ($IC_{50}$; 0.56 mg/mL), super oxide radical ($IC_{50}$; 9.53 mg/mL) and hydroxy radical scavenging activities ($IC_{50}$; 169.2 ${\mu}g$/mL) of FNPL were increased 19.6 (p<0.001), 1.4 (p<0.01) and 17.8 fold, respectively, compared to those for flour noodle (p<0.001). In conclusion, perilla leaf added to noodles at a final concentration of 19% (w/w) can increase the sensory and antioxidant properties of flour noodles.

The physicochemical properties of coarse semolina (CS), medium semolina (MS) and fine semolina (FS) were investigated to research method applied in noodles processing of Korean wheat semolina. Large particle (>250 ${\mu}m$) was over 75% in all semolinas, except for FS, and the particle distribution of MS and durum semolina (DS) was similar. Crude protein and crude ash were the highest in DS followed by CS>MS>FS. Crude lipid of DS was the lowest among samples and CS, MS and FS were not significantly different. L value was high in semolina with small particle distribution and starch damage was the lowest in DS followed by FS>MS. Amylose content was high in DS (29.80%) and FS (29.08%) with small particle distribution. Water binding capacity was the highest in DS, and FS showed the highest water binding capacity among Korean wheat samples. Solubility and swelling power were noticeably high in FS with low starch damage and small particle distribution. In scanning electron microscope (SEM), FS and MS showed distribution of separated fine particles of flours. From these results, the physicochemical properties of semolina showed many differences by grinding methods. FS should be applied in noodles processing through additional examination about characteristic of noodle making.

In this study, buckwheat four was classified by the order of extraction from the inmost layer to the outmost layer, and was designated as $B_1,\;B_2,\;B_3,$ and the mixed flour of $B_1,\;B_2,\;B_3$ (1:1:1) was named $B_0$. To improve the dried noodle-making properties, various levels of strong wheat flour and additives such as sodium alginate (SA) and xanthan gum(XG) were added to buckwheat. 1) The buckwheat $B_2$ and $B_3$ flours contained much higher amounts of crude ash, protein and fat than the $B_1$ flour. 2) Buckwheat $B_3$ flour demonstrated lower maxium viscosity value by amylograph than the $B_1$ flour, but it demonstrated 2 times higher maximum viscosity value than wheat flour. Buckwheat $B_1$ flour demonstrated 4-5 times higher maximum viscosity value than wheat flour. Addition of SA and XG increased the viscosity of the flour mixtures. 3) It was possible to make dried noodles from the composite flour of (buckwheat 40 %+wheat 60 %). The lesser the quantity of buckwheat flour was, the better the kneading property of mixed flour was. 4) SA and XG, which were added at the level of 1.0-1.5%, significantly improved dough making properties and the cooking quality of the noodles.

Quality characteristics and functional properties of Korean wheat noodle with brassica oleracea L. powder were investigated to develop health promoting and high quality product. Brassica oleracea L. powder was extracted with water and $70\%$ ethanol, and the extracts were tested its electron donating ability (EDA) and nitrite scavenging ability (NSA). Quality characteristics of the noodle were evaluated by its color, flavor, moisture, softness, texture and taste evaluation. Microbiological Quality was also tested counting total viable cells. EDA was highest at 1000 ppm of both water extract ($64\%$ of EDA) and ethanol extract ($76\%$ of EDA). NSA was highest pH 1.2 of both water extract ($42\%$ of NSA) and ethanol extract ($46\%$ of NSA). In antimicrobial activity test, Korean wheat noodle with $3\%$ pine pollen powder displayed $0.5{\~}1$ log cycle of total viable cell counts lower than that of control at 5 days of storage. Sensory evaluation of Korean wheat dried and cooked noodles with $3\%$ Brassica oleracea L. powder showed significantly higher scores in overall.
