  • 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.

  • The rheological properties of hard red winter, western white and Australian standard white wheat flours and of HRW-WW and HRW-ASW wheat flour blends having the same protein content were studied. Cooking properties of dry noodles prepared from HRW-WW and HRW-ASW wheat flour blends were also investigated. The noodles were prepared with salt and alkaline reagent. The salt and alkaline concentrations used were 1.7% and 0.17%. respectively, based on the weight of wheat flour. The alkaline reagent was an equal mixture of sodium carbonate and potassium carbonate. The HRW-ASW wheat flour blend had higher farinograph absorption and slightly stronger curve than HRW-WW wheat flour blend. Salt decreased the absorption of wheat flours by 2 and of wheat flour blends by 1%. However, alkaline reagent essentially had no effort on farinograph absorption. Salt and alkaline reagent strengthened the dough of wheat floors and wheat flour blends, with the former being more effective. No significant differences in pasting properties between HRW-WW and HRW-ASW wheat flour blends by amylograph were observed. There were no significant differences in rate of increase of weight or volume between noodles prepared from HRW-WW and HRW-ASW wheat flour blends. Alkaline reagent did not affect the weight gain of noodles hut lowered the volume gain. Breaking force of dry noodles and cutting force of cooked noodles were similar between the two noodles. Alkaline reagent increased both the breaking and cutting forces of noodles. Sensory evaluation revealed that the noodles prepared from HRW-WW and HRW-ASW wheat flour blends were slightly different. but not different from each other by preference test.

  • The purpose of this study was to determine the characteristics of noodles with added Polygonati odoratum powder. Noodles' water binding capacity increased with increasing amounts of Polygonati odoratum powder. Solubility and swelling power increased with the temperature increasing proportionally to the amounts of added Polygonati odoratum powder. The gelatinization time decreased with increasing of Polygonati odoratum powder. The rate of weight increase and water absorption of cooking noodles decreased with increasing Polygonati odoratum powder. But the turbidity of the soup increased. With increasing Polygonati odoratum powder, L-values were shown to decrease and a and b value were increased. The results of sensory evaluation were that noodles containing under 5% Polygonati odoratum powder were rated as high-quality noodles.

  • We conducted this study to investigate the amount of RS and cooking characteristics of the commercial extrusion-cooked noodles. Ten kinds of noodles were selected and grouped according to the storage conditions; dry noodles (3), refrigerated noodles (2), freeze noodles (4), and dry noodle made from wheat flour as a control (not extrusion-cooked). The total starch of commercial noodles ranged from 62.50% to 84.13%, Refrigerated Naengmyeon and dry Dangmyun had high proportions of total starch (respectively 84.13% and 80.13%, respectively). The amounts of apparent amylose ranged from 25.01% to 42.93% and RS ranged from 0.61% to 5.99%. A high proportion of the total starch was rendered digestible by extrusion cooking, and a small amount of RS remained in the samples. Dry Dangmyun had the highest percentages of RS (5.99%), followed by refrigerated Naengmyeon C (2.41%) and dry Jjolmyeon (1.94%), and those of the other noodles were lower than that of the control (1.86%). Cooking properties and texture measurements were evaluated. Cooking loss and turbidity of cooking water were highest in dry Jjolmyeon and dry Naengmyeon. There was little cooking loss in dry Dangmyun and freeze rice noodles. In particular, dry Dangmyun and refrigerated Naengmyeon C containing high amounts of RS and amylose had relatively high measurements of hardness and tensile strength.

  • The objectives of this study was to investigate the properties and stability of the wet noodles added to nanoemulsion as a industrial model system, and in so doing, survey practical applicability in the food industry. In order to test out these objectives, the characteristics and stability of the wet noodles added to nanoemulsion were investigated and their cooking characteristics and capsaicinoids loss were examined. As a result, the test results showed that the findings indicated that the post-cooking loss of capsaicinoids in the wet noodles added to double-layer nanoemulsion covered with chitosan was less than the losses in the wet noodles added to any other noodles. More especially, this demonstrates that the noodle added to double-layer nanoemulsion covered with chitosan scored significantly higher than the others with reference to their cooking properties, color, texture, stability for storage stability, and sensory evaluation. These results show that the findings of this study demonstrated that the noodles added to nanoemulsions could be produced as a food-grade merchandise because they could provide enhanced encapsulation capacity of capsaicinoids and higher acceptability.

  • 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.

  • Quality characteristics of conventional and whey noodles were investigated by studying the textural properties. cooking properties, and sensory characteristics. The whey noodles were prepared by mixing whey powder with the wheat flour before noodle production, with the mixture ratio ranging between 1 and 7% in volume. The results are summarized as follows : the addition of whey powder noticeably improved the textural characteristics of the cooked noodles, i.e. hardness, gumminess, and chewiness. The best results were obtained using the following percentage of whey in the mixture: the hardness with 1% added, the gumminess and chewiness with 3% added, and the elasticity with a 7% addiction. The tension force also increased with addition of whey powder, The highest tension force was obtained when 3% of the whey was mixed. While the cooking water of the general noodles displayed a light reddish tint, the cooking water of the whey noodles had a yellow-greenish tint. The cooking water of the whey noodles was more turbid than that of the conventional noodles. The whey noodles increased in volume more than the conventional noodles. after cooking. There was no difference in weight increase and water absorption rates between both types of noodles. More favorable results were shown for appearance, color, texture, and sensory acceptability in the whey noodle than in the conventional noodles.

  • We examined the chemical properties of leek and dropwort and prepared the noodles with the dried powder of them, to develope functional processing floods which contain biological active compounds. The groups were divided by the drying methods as follows: hot air drying at 50$\^{C}$ (A), hot air drying after blanching for 30 sec (B), hot air drying after steaming for 2 min (C) and freeze drying (D). We had analyzed the content of vitamin C, total chlorophyll, and phenolic compounds and measured the hunter color values of dried powders individually. The contents of evaluated compounds were higher in A and D than in B and C groups and also the electron donating activity of A and D was stronger than B and C. The cooking properties of noodles prepared with leek and dropwort powder were examined. After cooking, the weight and volume of noodles prepared with powder were lower than those of control The turbidity of noodle soup were increased as the adding ratio was increased. The cutting strength of cooked leek noodles with A and B powder was similar to that of control, in case of dropwort, cooked noodles with D showed similar to that of control. The cutting strength of cooked noodles were decreased as the adding ratio were increased. The electron donating activity of noodles with vegetable powders showed high than that of control The sensory evaluation showed that significant difference between noodles with 2.5 ?/e addition groups and control was not recognized but was recognized between noodles with 5% addition groups and the control.

  • 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.

  • We investigated how the addition of polypeptides to instant fried noodle dough affects the dough properties, starch gelatinization, and textural properties of cup-type instant fried noodles. After comparing farinograph results of 100% wheat flour with 1% wheat flour substituted with gluten, there was a small difference in the mechanical dough properties. However, in the case of 1% wheat flour substituted with gluten peptides, the dough development time increased, dough stability decreased, and weakness increased. On the other hand, when gluten or gluten peptides were added, starch gelatinization did not change significantly. At the steaming stage, substitution with gluten peptides or soybean peptides markedly changed the molecular weight distributions of extractable polypeptides. Especially in the case of wheat flour substituted with 1% gluten peptides, the relative portion of low Mw extractable polypeptides (2.5-50 kDa) decreased more compared to a control. Also, the hardness and chewiness decreased in cooked cup-type instant fried noodles containing gluten peptides. This suggests that the addition of gluten peptides can reduce the rehydration time of cup-type instant fried noodles.
