  • 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.

  • Quality of noodle processed by addition of hot water extract powder from roasted safflower seed (RSHE) was investigated. Proximate compositions of RSHE was 4.70% of moisture, 32.63% of crude Protein, 6.52% of crude fat, 15.62% of crude ash and 40.53% of carbohydrate. There was no significant difference (p<0.05) in hunter's color value between noodles with and without RSHE. The ‘L’vague of noodle processed by addition of powder from roasted safflower seed (RSP) was very low and significantly different (p<0.05) from other products. With the increase of RSHE addition, the volume and weight of cooked noodles increased (R$^2$=0.9688). The breaking force of dry noodle decreased with the increase of RSHE addition. In the mastication test of cooked noodles, max. weight, strength and hardness increased with the increase of RSHE addition. Dry noodle with 0.3% and 0.5% RSHE recorded high rank, but that with RSP recorded the lowest rank in score of appearance and color by sensory evaluation. The noodle processed with 0.3∼0.5% RSHE showed high sensory quality.

  • Laver noodles were prepared with composite flour containing various ratios of laver powder sifted through 100-mesh sieve and their cooking characteristics were evaluated. Farinograph test results with the composite flour showed that water absorption rate increased linearly as the content of laver powder increased from 2% to 8%, while dough stability decreased linearly with the laver content. Dough development time increased 2.65-3.75 times by adding laver powder. DSC endotherms indicated that onset temperature $(T_o)$, peak temperature $(T_p)$, and conclusion tempearture $(T_c)$ of composite flour starch gelatinization shifted to a higher temperatures as the laver powder content increased. Difference in laver species (e.g., Porphyra dentata and Porphyra tenera) did not affect dough characteristics and surface color of doughs and noodles made with composite flours. From the sensory evaluation test for noodles, a laver noodle containing 4% roasted Porphyra dentata was the most preferred among the noodles tested.

  • This study was carried out to find major factors affecting the color of wheat flour and noodles and develop simple analysis method for the breeding of wheat cultivars suitable for producing flour and noodles with bright color which are preferred by consumers. Customers who buy white noodle or flour prefer bright-colored food to dark-colored products. We evaluated grains of 25 Korean wheat cultivars for chemical composition, grain characteristics, and color change of noodle dough sheets during storage. Polyphenol oxidase (PPO) has been connected to discoloration of white salted noodles and other wheat end products. The grain PPO activity was reduced as the 1,000 grain weight, grain ash content, and protein content decreased. The grain PPO activity was positively correlated with the total polyphenol content ($r=0.609^{**}$) and iron content ($r=0.655^{**}$). Lightness, protein, polyphenol and Fe content of flour were positively correlated with PPO activity of grain. Cultivars with higher grain PPO activity showed darker noodles and were more easily discolored during the storage (from 2 hr to 48 hr). Thus, PPO activity can be used as a selection index in a breeding program for wheat cultivars of bright-colored flour.

  • This study was conducted to evaluate quality characteristics of noodles when different concentrations of chlorella extract powder were added to the wheat flour. The characteristics of noodle including cooking properties, color, mechanical texture properties, and sensory properties were determined. The noodles containing chlorella extract powder exhibited higher values in cooked weight, volume, moisture absorption, and cooking loss. When the amount of chlorella extract powder increased, the Hunter L(lightness) value, a(redness) value of cooked noodles decreased but b(yellowness) value increased. From the textural properties measured by texture analyzer, the noodles with chlorella extract powder were significantly lower in hardness, cohesiveness, springiness, gumminess, and chewiness than those of 100% wheat noodle. The results of sensory evaluation of cooked noodles containing chlorella extract powder indicated that the cooked noodle with 1.5% chlorella extract powder showed the highest value. Based on cooking properties and sensory evaluation, chlorella extract powder up to 1.5% could be substituted for wheat flour to improve the noodle quality.

  • Rice noodles are popular worldwide; however, no standard procedure is available for screening the potential for rice flour to make good quality noodles. This study reports two standard laboratory-scale procedures for preparing flat (sheet type) and extruded noodles. Eight rice cultivars were examined and the cooking loss and tensile strength of cooked noodles were determined. It was relatively easy to control the amount of water added to extruded noodles, whereas flat noodles were very sensitive to the amount of water used. Sheet formation was determined based on the amount of moisture content during preparation, and the Chenmaai cultivar was found to be most appropriate for both noodles making procedures and cooking and textural properties. Finally, good noodle making cultivar such as Chenmaai was less likely to be affected by the milling method.

  • Since Goryo was established during the early tenth century, Koreans have believed that Goguryo, which ruled almost all of the Manchurian territory, was one of the Three Kingdoms of their ancestors. This Korean perspective conflicts with the Chinese perspective that Goguryo was a Chinese local government in Manchuria and the northen parts of Korean Peninsula. Modern Chinese people wish, by the measure of Manchurian Project, that the history of China includes the histories of all the ethnic groups in Manchurian territory. Although Chinese people attempt unreasonably to regard Goguryo as an old Chinese local government, it is not from the Korean nationalistic viewpoint but from the scientific historian viewpoint that this Chinese perspective should be criticised and corrected. We should remember that the nationalistic viewpoints in East Asia may hinder the establishment of mutual cooperation and security in the region.
