  • Organic acids-eggshell calcium salts were prepared to recycle calcium component from discarded egg shells, and the effects of addition of the salts on dough characteristics of raw noodle and physical properties of cooked noodle were also investigated. Based on Farinograms, calcium malate (CM) affected absorption, stability time, and development time more considerably than calcium citrate (CC). Maximum concentrations of both CM and CC with little influence on dough characteristics were found to be 0.1% and 0.4%, respectively. Addition of calcium salts led to reduce the volume expansion rate of cooked noodle and this was more clearly shown in a sample fortified with CM than CC. As for CC, addition of more than 0.6% resulted in rapid increase in springiness which was in a good agreement with sensory evaluation results. Calcium ion concentration of cooked noodle fortified with 0.4% CC was 48 ppm, equivalent to 86 mg of calcium obtained from 200 g of cooked noodle.

  • Three rice varieties of Akibare (japonica), Milyang 30 (indica) and Taebaeg (indica) were investigated for their changes in sensory and physical qualities of cooked rices during storage at the temperature range of $4^{\circ}C$ and $70^{\circ}C$ for 25 hours, The qualities studied were sensory attributes of texture which were evaluated by multiple comparison method and physical characteristics of texture measured using with rheometer. Physical Properties of hardness, adhesiveness and elasticity of cooked rices were found to be different among the rice varieties and were affected by storage conditions. Higher values in hardness and elasticity and lower values in adhesiveness were measured for cooked rices of Akibare immidiately after cooking. Those physical values were changed by a steady decrease in hardness and elasticity and increase in adhesiveness during storage for 25 hours. Correlations between sensory and physical characteristics of texture was found a significant relationships between gumminess and hardness (r=0.696), gumminess and adhesiveness (r=-0.800) and gumminess and elasticity (r=0.806).

  • This study was carried out to investigate the quality of cooked rice prepared by-an electric pressure cooker (EPC) and an electric cooker (EC) during storage at different temperatures. Four rice cultivars were used (Ilpoom, Saechucheong, Sindongjin, and Sura). The cooked rice samples were stored at room and warm temperatures for 48 hr, and at refrigerator temperatures for 10 days. Immediately after cooking, the moisture content of the EPC rice was lower than that of the EC rice; yet pH was higher for the EPC rice. The L-value of the EPC rice was reduced due to an increasing b-value. The overall acceptability of the EPC rice was high; in particular, it scored high for a roasted nutty flavor and texture. During storage, moisture content and pH decreased regardless of the cooking method. L-, a- and b-values were similar at room and refrigerator temperatures over the entire period, whereas the a-value (greenness) of the EC rice stored at warm temperature slightly decreased and the b-value (yellowness) increased after 24 hr, resulting in a decreasing L- value. Also, sensory characteristics were not significantly different for the samples stored at room temperature for 48 hr; however, at warm and refrigerator temperatures, the sensory characteristics were significantly different after 24 hr and 3 days, respectively. In conclusion, the quality of the cooked rice was effectively preserved during storage at room temperature, and qualify deterioration oaf dependent on using warming equipment as well as the rice cultivar.

  • Rice (brown rice: milled rice=50:50) was cooked using different concentrations of hyaluronic acid (HA) solution (0.1, 0.3, 0.5, and 0.7%, respectively) as the cooking water, and the properties of the cooked rice were compared. As the HA content increased, the moisture content of the cooked rice significantly increased, and the textural properties, including hardness, cohesiveness, and adhesiveness, except springiness, significantly decreased. For color, as the HA amount increased, the L* value decreased, whereas the b* values increased. The free radical scavenging effect and total polyphenol content also increased significantly as the amount of HA increased. In the sensory test, the hardness of the samples containing HA was higher than that of the control; however, there was no significant difference in the overall acceptability. Based on the above results, much softer cooked brown rice could be produced using HA solution (up to 0.7%) as the cooking water, and additional beneficial characteristics, such as antioxidant effect, can be obtained.

  • This study compared aroma compositions and sensory aroma attributes of raw and cooked Tenebrio molitor larvae (mealworms). Main sensory aroma attributes of raw mealworms were strong wet-soil-like, and less-intense oily, shrimp-like and sweet-corn-like. Quantitatively, the major aroma components of raw mealworms were hydrocarbons and aldehydes. As cooking proceeded, sweet-corn-like, roasted, and fried-oil-like sensory attributes were increasingly perceived with steaming, roasting, and frying, respectively. Some pyrazines, pyrrolidines, and carbonyls increased or appeared in roasted and fried mealworms. Partial least squares regression also showed differences in raw and cooked mealworms based on aroma components and their sensory attributes. Unlike raw mealworms, steamed mealworms had a relatively strong sweet-corn-like aroma attribute, which was related to 2,4,6-trimethyl-heptane, 2,4-dimethyl-dodecane, and 3,5-dihydroxy-6-methyl-2,3-dihydropyran-4-one. In comparison, roasted and fried mealworms exhibited roasted, shrimp-like, and fried-oil-like aroma attributes, which were associated with intermediates of the Maillard reaction and lipid oxidation, such as pyrazines, alcohols, and aldehydes. This result during thermal reactions was very similar to those of meat and/or seafood. The use of mealworms as a savory-type flavor enhancer can be expected.

  • In this study, we investigated the quality characteristics of noodles supplemented with lyophilized leg-meat powder from the red snow crab, Chionoecetes japonicus (CP). The noodles were prepared by adding 0, 2, 4, 6, 8, 10% of CP on a wheat-flour basis. The ash, crude protein and crude lipid contents of noodles increased with increasing CP content. The cooked weight, volume and water absorption values of noodles decreased, whereas the turbidity increased, with increasing CP content. The L values of the noodles decreased with increasing CP content, whereas the a and b color values increased. The hardness, gumminess and chewiness values increased with increasing CP content increased, while springiness and cohesiveness showed no significant differences among the groups. In the sensory evaluation, cooked noodles with 4-6% CP had greater overall acceptability than the noodles with other CP levels.

  • This study was performed to find out the quality characteristics of rice noodles by addition of red ginseng(0, 2, 6, 10%). The quality characteristics of the sample were estimated in terms of general composition, growth of microorganism and sensory evaluation. The results from this study were as follows. The protein, lipid and ash contents did not show significant difference in any of the groups. In dry rice noodles, moisture content significantly decreased in red ginseng groups but, in half-cooked rice noodles, moisture content significantly increased in 6 % and 10% red ginseng added groups(p<0.05). The microbial count showed less growth in red ginseng added groups after 3 months(p<0.05). According to sensory evaluation, surface color proved very good in the 10% red ginseng added group among the training panel while very good in the 2% red ginseng added group among consumers. Flavor was good in red ginseng added groups(p<0.05). Taste was very good in the 3% red ginseng added group. Appearance and overall quality were highest in the 2% and 6% red ginseng added groups(p<0.05). Therefore, rice noodles containing 2% or 6% red ginseng were most preferable and safe during 5 months and 6 days in dry and half-cooked noodles respectively.

  • This study investigated the quality characteristics of $Jajang$ noodles with added spinach (20%, 30% and 50% based on water). Significant increases ($p$<0.05) were found in cooked weight, water absorption of cooked noodles, turbidity of soup, while soup volume did not changed in proportion to the addition of spinach. Decrease of L and a values and an increase of b values were shown with the increase of spinach concentration. For textural properties, hardness was the lowest in 50% spinach noodles and the highest in 20% spinach noodles. The cohesiveness and springiness values of 20% and 30% spinach noodles were superior to those of the control, but a rise in spinach concentration (50%) lead to a reduction these values. In a sensory evaluation, the most acceptable sample was the 30% spinach noodle sample. These results suggest an addition of 30% spinach is suitable for spinach $Jajang$ noodle processing.

  • This study investigated the quality of noodles containing different amounts of Ligularia fischeri powder (LFP). Noodles were prepared at ratios of 0, 1, 3, 5, and 7% LFP based on flour weight. Cooking quality, mechanical texture properties, and viscosity were measured, and a sensory evaluation was performed with the prepared noodles. Gelatinization points of the composite LFP-wheat flours increased. As measured via amylography, viscosity at $95^{\circ}C$, viscosity at $95^{\circ}C$ after 15 minutes, and maximum viscosity values of samples decreased, as the LFP content increased. As increasing amounts of LFP were added, the L, a, and b values decreased while color values, weight, and volume of cooked noodles increased, as did the turbidity of the soup. With regard to textural characteristics, LFP additive increased hardness, cohesiveness, and springiness, while decreasing adhesiveness. Sensory evaluation showed that high quality cooked noodles could be produced by inclusion of 3% LFP.
