  • Quality characteristics of griddled miljeonbyeong containing vegetable juice were assessed by conducting sensory tests and measuring texture and color. When varying amounts of carrot/or spinach juice was added to miljeonbyeong, the sensory preferences of appearance and texture were higher in miljeonbyeong containing a small amount of carrot and spinach vegetable juice, and the preferences of smell and taste were higher in miljeonbyeong containing a large amount of carrot and spinach juice. Overall, preference was highest in miljeonbyeong supplemented with 30 g carrot juice and 10 g spinach juice. Overall preference correlated significantly with appearance (r=0.44) and texture (r=0.47). In miljeonbyeong containing vegetable juice, tensile strength decreased significantly with increasing amounts of carrot juice (34.98~30.82) or spinach juice (40.84~37.07). In all miljeonbyeong samples, tensile strength increased slightly in 1 hour but rapidly increased after 2 hours. Lightness progressively decreased. A-value increased (3.46~9.63) and b-value increased with increasing amounts of vegetable juice added. No difference in the b-value increase was evident between carrot juice (15.19~26.43) and spinach juice(18.19~24.40). Tensile strength was markedly lower in miljeonbyeong amended with carrot juice (34.98~30.82g) or spinach juice (39.05~32.67 g), which contained fat-soluble pigment, as compared with vegetable-free miljeonbyeong (44.81 g), but the addition of beet juice (45.30~44.78 g) containing water-soluble pigment did not lower the tensile strength of miljeonbyeong compared to vegetable juice. In order to improve the texture of miljeonbyeong containing vegetable juice, tensile strength was measured in miljeonbyeong prepared with 30 g carrot juice or 10 g of spinach juice, which produced the highest sensory test scores, and additionally amended with potato starch, corn starch, glutinous rice flour, strong flour or yam powder with a consequent reduction in the content of wheat flour. Improvement was noted in carrot juice-containing samples prepared with 6 g corn starch, 15 g potato starch and 15 g hard wheat flour, and in spinach juice-containing samples prepared with 6 g corn starch, 6 g potato starch, 6 g hard wheat flour and 15 g dried yam powder.

  • Effects of soaking time and particle size on physicochemical properties of nonwaxy rice flour were investigated. Nonwaxy rice grains were soaked at $4^{\circ}C$ for 0, 1, 12, and 24 hr, dried at room temperature, and milled, Resulting flours were passed through 45-mesh ($<355{\mu}m,\;IL45$) and 100-mesh ($<150{\mu}m\;IL100$) sieves and separated into $<40{\mu}m\;and\;40-100{\mu}m$ series. IL45 series showed higher amount of large particles ($40-100{\mu}m$) than IL100 series. As the soaking time increased, protein and ash contents decreased, and amylose content, water-binding capacity, swelling power, and solubity of nonwaxy rice flours increased. Swelling power and solibility of nonwaxy rice flours also increased between $65-85^{\circ}C$. Water-binding capacity, swelling power, and solubility of IL100 series were higher than those of IL45 series. 12 hr-soaked nonwaxy rice flour pastes showed higher peak viscosity and breakdown but lower setback and visicosity at $95\;and\;50^{\circ}C$ than 1 hr-soaked ones. X-Ray diffractograms of nonwaxy rice flours were not affected, whereas surface appearance was affected, by soaking time and particle size.

  • ${\alpha}-amylase$ activities of bean water was not significantly influenced by bean water concentrations but they were remarkably influenced by different temperatures and substrates. ${\alpha}-amylase$ activities of bean water on cooked starch were significantly higher than those on raw starch. ${\beta}-amylase$ and glucoamylase activities in 14% bean water were significantly higher than those in 7% bean water. Yukwa paste is glutinous rice flour paste. Bean water was added to Yukwa paste by 0, 7, 14% and incubated 0, 3, 6, 9, 12 hours at $60^{\circ}C$. The pH of Yukwa paste increased with bean water concentration and decreased with the incubation time. The viscosity decreased with bean water concentration and incubation time. The ruducing sugar content of Yukwa paste increased with bean water concentration and incubation time. The changes of reducing sugar content in cooked Yukwa paste were much higher than those in the raw one. ${\alpha},\;{\beta}-amylase$glucoamylase activities of Yukwa paste also increased with bean water concentration, and their activities were much higher on the cooked glutinous rice flour than those on the raw one. The SEM observation on the freeze-dried flour of Yukwa paste showed breakdown of amylopectin structure by addition of bean water in the paste.

  • To develop health functional gluten-free rice madeleines added with pine needle, rice flours were prepared by adding different contents (0.6, 1.2, and 1.8% on rice flour basis) of freeze-dried pine needle powder (PP) and extract (PE, by pressing pine needles). The preparation, textural and sensory properties, and antioxidative activities of rice madeleines were investigated. The antioxidative activities of rice madeleines added with PP and PE were higher than those of the control and were significantly different from each other. The specific volume of rice madeleines added with PE was higher than that added with PP. Lightness and yellowness decreased with increasing PP or PE content, whereas redness showed the reverse trend. Textural properties were also significantly different according to pine needle type and content. Hardness values of rice madeleines added with 1.2 and 1.8% PP or 1.2% PE were reduced compared to that of control. Hardness values increased while other textural properties decreased during storage. In the sensory test, color, flavor, and taste scores increased with increasing PP or PE contents, whereas flavor and overall quality scores were highest in rice madeleine added with 1.2% PP. Based on these results, pine needle powder addition improved antioxidative activities and overall quality.

  • This study is performed to investigate the quality characteristics of sulgidduk added with cheonnyuncho fruit powder. Sulgidduk was prepared with freeze-dried cheonnyuncho, rice flour, sugar syrup and salt. The sulgidduk was made with various amounts (0, 3, 6, 9, 12%) of added cheonnyuncho fruit powder. The proximate composition, pH, Hunter's color value, texture profile analysis, sensory characteristics and SEM of cheonnyuncho sulgidduk were being examined. The addition of cheonnyuncho fruit powder has a tendency to decrease the moisture contents of sulgidduk while the crude ash, crude lipid and crude protein increased. The pH of sulgidduk decreased when the amounts of cheonnyuncho fruit powder increased. As the amount of cheonnyuncho fruit powder increased, the lightness (L) decreased, while the redness (a) and yellowness (b) increased. In texture profile analysis, the hardness decreased with increasing cheonnyuncho fruit powder contents, whereas cohesiveness, springiness, gumminess and brittleness increased. The results of sensory evaluation showed that the sulgidduk with 3%, 6% of cheonnyuncho fruit powder got the highest scores on the color, taste, springiness and acceptability. The air cells of sulgidduk observed by SEM were big and uniform with the amount of cheonnyuncho fruit powder increased. In conclusion, these results show that the quality and preference increased when 3%, 6% of cheonnyuncho fruit powder was added to the sulgidduk.

  • The purpose of this study is to understand the Chinese noodles(mian tiao). Wheat seems to have been cultivated 3-4,000 years before according to the archaeological evidences from the neolithic sites. The five grains(rice, millet, beans, barley, barnyard millet) already appeared in the period prior to Chin dynasty and were used as whole grain, but it was not until Chun Chu Zhan Guo period that the introduction of the flouring method stimulated the cultivation of wheat. In Chin-Han period, when water power and animal force were put into usage to facilitate the mass production of wheat flour, 'Bing', a designation for all the food made of wheat first appeared in the literature, and it was this 'Bing' that had later developed into noodles. In Wei Chin Nan Bei Chao period, roasted 'Bing', namely 'Kao-Bing' made its first appearance, and in Tang period, various noodles were created with the increase of restaurants specialized in noodles. In Song dynasty, 'La-Mian', the noodles stretched and beat from noodle dough, was first introduced, and in Yuan period, invention of drying method made the appearance of dried noodles, 'Gua-Mian', possible, which was good for easy and long preservation. Qing dynasty developed the noodles with a variety of assorted ingredients. The Chinese noodles are classified by various standards such as main ingredients, cooking methods, kinds of sauce, secondary ingredients, shape, eating method, flavor, and look.
