Noodle texture parameters of Korean style wet and dry noodles and relationships between noodle quality and flour characteristics were evaluated for two years, 1997 and 1998, and at two locations, Suwon and Deokso, using Korean winter wheat cultivars and lines. No significant difference for chewiness was found between cultivars over locations. Noodles made from flours from 1997 showed significantly higher chewiness than those from 1998. Chewiness of cooked noodles showed positively significant correlations with protein content and SDS sedimentation volume and negatively significant correlations with starch peak viscosity and flour swelling volume. Korean winter wheat cultivars, except for Gobunmil, Keumkangmil Tapdongmil, Suwon 265 and Suwon 280, showed chewiness of cooked noodles similar to commercial flours used for noodle making in Korea and Japan.

This study was carried out to investigate the quality characteristics and storage of wet noodle with added Cheonnyuncho powder. Wet noodles were prepared at concentration of 1, 3, and 5%(w/w) of the fruit based on flour weight. Moisture content of the noodles with or without Cheonnyuncho powder was 34~36%. Ca, K, Mg, Fe, Mn and Zn contents of Cheonnyuncho noodle were increased at increasing concentrations of Cheonnyuncho powder. Cooked weight, volume, and water absorption decreased with increased fruit powder, whereas turbidity increased. For hunter's color values of noodles, L(lightness) and b(yellowness) values decreased with increasing concentration of Cheonnyuncho powder, whereas a(redness) value increased. For mechanical characteristics of the noodles, adhesiveness, cohesiveness, chewiness, elasticity, and brittleness of cooked noodle with Cheonnyuncho powder were lower than those of control. The pH of Cheonnyuncho noodle was lower than that of control during storage. Bacterial counts of wet noodle with 1% and 3% fruit powders were lower than those of the control and 5% fruit powder on the 8th day of storage at $5^{\circ}C$. From the sensory evaluation, texture, taste, and overall preference were not significantly different between the control and fruit group, but the color of 5% Cheonnyuncho noodle was significantly higher than that of control (p<0.05). In conclusion, the results of this study suggest that the addition of 1% and 3% Cheonnyuncho powder in combination with flour tended to improve antimicrobial effects during storage when compared to control.

To determine the cause of wet noodle spoilage, microorganisms isolated from wet noodles were identified and characterized. In addition, the growth inhibitory effects of organic acid mixture (OA: lactic acid 27.8%, acetic acid 12.0%, succinic acid 1.0%) and sodium dehydroacetate (SD) on the isolated strain were estimated in nutrient broth medium. The isolated strain was Gram-positive, rod shaped, motile, and spore forming. Based on physiological characteristics and the API 50 CHB-kit test results for the assimilation of 49 carbohydrates, the isolated strain was identified as Bacillus amyloliquefaciens (92.6%), which is able to degrade starch. Decimal reduction times (D-values) at 100, 105, and $110^{\circ}C$ for spores of B. amyloliquefaciens were 8.5, 5.1, and 2.5 min, respectively, and the z-value was $12.8^{\circ}C$. We estimated that B. amylo-liquefaciens isolated from spoiled wet noodles was a thermophilic species having high heat-resistance. Viable cell numbers in wet noodles and broth medium inoculated with B. amyloliquefaciens were decreased by 2-4 log cycles by combined treatment with 0.03 or 0.05% OA and 0.3% SD. These results revealed that OA combined with SD could be used as a potential agent to inhibit B. amyloliquefaciens in wet noodles.

This study was conducted to investigate the properties of wet noodle when different concentrations of Prunus mume juice were added to the wheat flour. The characteristics of wet noodle including cooking properties, color, mechanical texture properties, and sensory quality were determined. The compositions of Prunus mume were 88.19% moisture, 0.45% crude ash, 4.04% citric acid and 0.41% total sugars. The pH of Prunus mume was 2.76. The moisture absorption rate, weight, volume and turbidity of cooked noodles added with Prunus mume juice were lower than reference sample. When the amount of Prunus mume juice increased, the Hunter L(brightness) value, a(redness) value of cooked noodles decreased but b(yellowness) value increased. Instrumental rheological characteristics of wet noodle containing Prunus mume juice were measured with a texture analyzer. The hardness, adhesiveness, cohesiveness, springiness and gumminess of wet noodle with 20% Prunus mume juice were higher than others. However, the hardness of cooked noodle decreased with the increase in the amount of Prunus mume juice into noodle. The adhesiveness, cohesiveness, springiness and gumminess of cooked noodles added with Prunus mume juice were higher than reference sample. The results of sensory evaluation of cooked noodles containing Prunus mume juice indicated that the appearance, color, taste and chewiness of the cooked noodle with 10% Prunus mume juice showed the higher preference than others. Based on cooking properties, rheological and sensory evaluation, addition of 10% Prunus mume juice suggested to be acceptable for processing wet noodle.

This study evaluated the quality characteristics of semi-dried noodles prepared with different water contents (wet noodles; 32, 24, 22, 20%, dry noodles; 12%). The drying process was carried out in a drying chamber at $13{\sim}18^{\circ}C$ temperature and 75~95% humidity. The proximate composition of Korean wheat flour was as follows: water $22.1{\pm}3.64%$, protein $8.6{\pm}0.13%$, fat $1.3{\pm}0.10%$, ash $0.7{\pm}0.02%$, carbohydrates $67.3{\pm}0.10%$. As water contents decreased, both L and b values significantly decreased before cooking of noodles, whereas L, a, and b values were not significantly different after cooking of noodles. Weight, water absorption, and volume of cooked noodles significantly increased as water content decreased, whereas turbidity of soup was not significantly different. Cutting hardness before cooking of noodles significantly increased as water content decreased. Sections of noodles after cooking by SEM (scanning electron microscopy) showed roughness and fewer round starch particles as water content decreased. For overall preferences according to the sensory evaluation, noodles prepared with different water contents were not significantly different. According to the results, semidried noodles have development potential to complement the disadvantages of both wet noodles and dry noodles.

본 연구는 생면의 저장성을 연장시키기 위하여 주정처리와 AC 처리 및 주정과 AC의 병용처리를 하여 $10^{\circ}C$에서 저장기간에 따른 품질의 변화를 조사하였다. AC를 처리한 생면은 대조구와 주정을 처리한 생면보다 pH가 높게 나타났고, 저장기간이 늘어남에 따라 생면의 pH는 약간 감소하였다. AC와 주정을 첨가하여 제조한 생면을 조리한 후 경도, 부착성, 탄성, 응집성, 검성, 씹힘성을 측정하였을 때 첨가제에 관계없이 유의적으로 달랐으나 그 차이는 미비하게 나타났다. 생면의 저장기간 동안 일반세균수는 대조구는 7일, 주정처리는 14일에 일반세균수의 기준치인 6.00 log CFU/g을 넘어섰다. 그러나 AC 0.2%와 주정을 함께 첨가 시 미생물의 생육이 억제되어 생면의 저장성이 크게 증가하는 것으로 나타났으며 AC만 0.2% 첨가 또는 AC 0.1% 및 주정 첨가도 일반세균 증식을 효과적으로 억제함으로써 저장기간이 연장되는 결과를 보였다. 조리된 생면의 관능검사에 있어서 저장기간 동안에 AC를 처리한 생면은 관능적 특성을 더 오래 유지하였으나 AC의 첨가율에 따른 유의적인 차이는 보이지 않았다. 본 연구 결과 전반적으로 생면 제조 시 AC를 첨가하였을 때 $10^{\circ}C$에서 저장기간을 연장시킬 수 있을 것으로 사료된다.

This study was performed to provide basic data that will predict the usefulness of buckwheat sprout as food materials. The quality characteristics of noodles prepared with buckwheat sprout powder were investigated The buckwheat sprout powder was added to the noodles in 0, 2, 4, 6, and $8\%$ in proportion to the weight of wheat flour, respectively. The added amounts of buckwheat sprout powder did not affect the volume of the noodles. The weight of noodles was decreased, whereas tumidity of the soup after cooking the noodles was increased with the increment of the amount of added buckwheat sprout powder. The color of powder mixture, wet noodles, and cooked noodles was changed by the addition of buckwheat sprout powder. Lightness(L) was decreased, whereas yellowness(b) and redness(a) increased as the amount of buckwheat sprout powder increased. In the texture analysis, hardness and chewiness of wet noodles were increased significantly by the addition of buckwheat sprout powder. Hardness, chewiness, and gumminess increased significantly in the cooked noodles with more than $6\%$ substitution of buckwheat sprout powder. Other textural properties did not show any significant changes. The results of sensory evaluation revealed that the overall preference of noodles with 2 to $4\%$ substitution of buckwheat sprout powder was better than other sample groups. Therefore, the appropriate amount of addition for the buckwheat sprout noodles was 2 to $4\%$ buckwheat sprout powder in proportion to the weight of wheat flour.

This study evaluated the quality characteristics of wet noodles added with sword bean powder(0, 5, 10, 15%) to determine the most preferred noodle recipe for consumer's desire. The proximate composition of the sword bean powder was as follows: Moisture contents were $13.4{\pm}0.08%$, protein $30.2{\pm}0.12%$, fat $0.3{\pm}0.09%$, protein $1.0{\pm}0.11%$ and carbohydrates $55.1{\pm}0.12%$, respectively. Total amino acid content of sword bean powder was measured 23,054.266 mg/100 g, especially in the order of histidine, glutamic acid and aspartic acid. The flavonoid content of sword bean powder was 17.9750 mg%. Water-binding capacity increased as the level of sword bean powder increased. When viscosity of wheat flours containing sword bean powder was measured by amylograph, the gelatinization point increased significantly as the level of sword bean powder increased, but peak viscosity decreased. As the level of sword bean powder increased, L value decreased, whereas a and b values increased. Weight, water absorption and volume of cooked noodles prepared with wheat flours containing sword bean powder decreased, whereas turbidity of soup increased. For textural properties, addition of sword bean powder increased hardness, springiness, chewiness of cooked noodles, whereas adhesiveness decreased. According to sensory evaluation such as appearance, color, flavor, taste, texture, overall preference, it was revealed noodles with 10% sword bean powder was the most preferred. According to the results, the addition of sword bean powder positively affects the overall sensory evaluation of wet noodle, and 10% is the optimal level for addition.
