The principal objective of this study was to determine the effects of wheat flour ferment cultured with Lactobacillus acidophilus, specifically with regard to the preservation of noodles. The results showed that the addition of ferment to wheat flour during noodle preparation reduced the pH of the noodles, and no significant difference was observed in the L and ${\Delta}E$ values of the noodles adding 5% ferment. Total bacterial levels were decreased in the wet noodles to which more than 10% ferment was added, by a factor of log $10^3$ as compared to the levels seen in the control during storage. Deterioration became apparent at 4 days of storage in regular wet noodles, but did not occur until 6 days in the wet noodles to which 5% ferment was added, and not until 8 days of storage in the noodles to which 10% ferment was added. Cooked noodles deteriorated at 8 days after the beginning of storage, but the addition of 5% and 10% ferment extended that time to 12 days and 14 days, respectively. It was concluded that flour ferment cultured with L. acidophilus exerts favorable preservation effects on noodles and breads.

The influence of organic acid dips on the quality properties, color, cooking quality, textural and sensory properties, and reducing microbial population of LL(Long Life) noodles was studied. The contents of organic acid used were 0.2% based on flour weight and LL noodles were treated by dipping in pH $2.5{\pm}0.1$ for $60{\sim}90sec$. The whiteness of LL noodles treated with dl-malic acid was higher than that of others. The shear extrusion force and hardness of LL noodles treated with dl-malic acid were shown much higher value than those of others except treated with dl-malic acid. acetic acid(=1:1). At cooking quality examination of LL noodles treated with organic acids, weight of cooked LL noodles treated with dl-malic acid was decrease but volume was appeared in vice versa. Extraction amounts of LL noodles treated with dl-malic acid, dl-malic acid : acetic acid(=1:1) during cooking were much smaller than those of others. Total counts of microorganism of LL noodles treated with dl-malic acid,dl-malic acid. acetic acid(=1:1) were disappeared during storage at $30^{\circ}C$ but treated with latic acid, acetic acid were increase during storage. Sensory properties of cooked LL noodles which was treated with dl-malic acid showed quite acceptable.

This study investigated the quality of noodles added with different amounts of freeze-dried fish scale collagen mixture powder (FDCMP). Freeze-dried fish scale collagen mixture was prepared by mixing ingredients (fish scale collagen : herb extracts : dextrin : distilled water=1:0.75:0.25:2), which were freeze-dried. Noodles were prepared by adding 0.5, 1.0, 1.5, and 2.0% (w/w) FDCMP based on flour weight. Cooked noodle weight and volume decreased with increasing amount of FDCMP, whereas turbidity of soups significantly increased. The water-binding capacity of FDCMP was higher than that of flour. Uncooked and cooked noodles showed reduced L values as well as increased a and b values increasing amount of FDCMP in the flour composite. Hardness and chewiness of cooked noodles significantly decreased with increased FDCMP content. Adhesiveness, cohesiveness, and gumminess increased with increased FDCMP content. Springiness and resilience were not significantly different between the control and FDCMP group. Finally, sensory evaluation results indicated that texture, mouthfeel, and overall preference of noodles containing 0.5% FDCMP were higher compared to those of the other samples. Based on cooking properties and sensory evaluation, freeze-dried fish scale collagen mixture powder up to 0.5% could be substituted for wheat flour to improve noodle quality.

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.

End-use properties of six Korean waxy wheat lines and their parental plants were evaluated in this study. Korean waxy wheat lines showed unsuitable characteristics for end products, such as sticky crumb of bread, sticky cooked wet and dry noodles and small cookie diameter. Korean waxy wheat lines produced lower loaf volume and less desirable crumb grain structure of bread, and lower chewiness of cooked wet and dry noodles than their parental plants even though Korean waxy wheats were much higher in protein content and SDS-sedimentation volume than their parental plants. We observed adverse effects of high flour protein content in Korean waxy wheat lines, such as smaller cookie diameter and harder snapping force than those produced from their parental plants.

To investigate the Possibility of making noodle with Job's tears flour(JTV), it was mixed with wheat flour by the ratio of 60oyo. Making characteristics of noodle was studied in terms of cooking quality test, color measurement and sensory evaluation. The cooking quality of noodles with 10~40% JTF was almost same value as control in weight and volume of cooked noodle. Color difference ($\Delta$E) between noodles with JFT and control was revealed appreciable value. Though noodles with 10~30% JFT was not significantly different from control in color, only noodle with 10% JFT was same as control In texture by sensory evaluation test.

The purpose of this study was to investigate the quality characteristics and antioxidant activities of noodles added with red lentil powder (RLP). Noodles were prepared by addition of 0, 15, 30, and 45% powder to flour of the basic formulation. RLP noodles were evaluated for their cooking properties (weight, water absorption, volume, and turbidity), color values, texture characteristics, sensory characteristics, and antioxidant activities. The weight, water absorption, and volume of cooked RLP noodles increased according to RLP content. The turbidity values of cooking water increased according to RLP content. The L value of RLP noodles decreased with increasing amounts of RLP, whereas a and b values increased with increasing amounts of RLP. The texture characteristics of RLP noodles decreased compared to those of control noodles except for adhesiveness. Antioxidative activities of RLP noodles significantly increased with increasing RLP content (P<0.05). The sensory preference test revealed that RLP 30% noodles showed the highest scores for smell, taste, chewiness, and overall preferences. It is suggested that RLP 30% noodles could be substituted for wheat flour to improve noodle quality.

This study was conducted to investigate the effects of substituting whole barley flours on quality characteristics of noodles. Noodles were made with composite flour containing 20% whole barley flour of various hullless barley cultivars and the quality characteristics, ${\beta}$-glucan content and antioxidant characteristics were investigated. In amylogram characteristics, the initial pasting temperature and peak viscosity were increased, and setback was decreased in complex flour. Noodles containing barley flour had low lightness, yellowness and high redness compare to wheat noodle. Water absorption of cooked noodles was lower than wheat noodle. The value of swelling index was high in noodles containing non-waxy barley flour and low in noodles containing waxy barley flour. Hardness and gumminess of noodles were lower than wheat noodle. Noodles containing non-waxy barley had higher hardness, cohesiveness and gumminess than noodles containing waxy barley flour. Dahan, non-waxy barley cultivar showed similar characteristics with the wheat noodle. ${\beta}$-Glucan content and antioxidant activity were increased with adding barley flour. Cooked noodle had slightly high ${\beta}$-glucan content, low starch content and low antioxidant activity compared to value of uncooked noodle.

The effects of Ge-Geol radish powder on the physical and sensory properties of wet noodles were investigated by adding 4-16% Ge-Geol radish powder based on the flour source. The Ge-Geol radish powder additions significantly increased the redness of the uncooked and cooked noodles. For the texture profile analysis (TPA) of the wet noodles with added Ge-Geol radish powder, hardness, adhesiveness and resilience decreased, whereas chewiness increased. Changes in the volume and weight of the cooked noodles were not significantly different according to Ge-Geol radish powder concentration, but the turbidities of the soup increased. In sensory test, overall acceptability was significantly higher for the noodles with added Ge-Geol radish powder of concentrations between 4-8%. These samples had similar sensory texture properties as the control and had peculiar hot and cool tastes of the radish. Therefore, adding Ge-Geol radish powder at concentrations below 8% was good for making noodles that maintained a natural texture, and also gave an characteristic radish-like flavor to the noodles.

The principal objective of this study was to evaluate the quality characteristics of dried noodles when different concentrations of Boehmeria nivea powder were added to wheat flour. Cooking quality, mechanical textural properties, and viscosity were measured, and sensory evaluation was conducted with the prepared noodles. The gelatinization points of the composite Boehmeria nivea powder-wheat flours increased. The viscosity at $95^{\circ}C$, viscosity at $95^{\circ}C$ after 15 minutes, and maximum viscosity values of the samples decreased, as the Boehmeria nivea powder content increased as measured via amylography. The L and b values decreased and a value increased with increasing amounts of Boehmeria nivea powder. Further, the color values, weight and volume of the cooked noodles increased, along with the turbidity of the soup with increasing amounts of Boehmeria nivea powder. Regarding textural characteristics, Boehmeria nivea powder additive increased hardness and reduced adhesiveness, cohesiveness, and springiness. Overall, noodles prepared with 15% Boehmeria nivea powder were preferred compared to other noodles, according to the results of our sensory evaluation.
