Effects of autoclaving-cooling cycled waxy rice(Hwasunchalbyeo) starch(ACW) on textural and sensory properties of Injulmi were investigated. The protein, ash and lipid contents of waxy rice flour were higher than those of waxy rice starch and ACW. The RS level of ACW was 8.21%. By increasing ACW content added to Injulmi, hardness and adhesiveness of Injulmi decreased, Hunter color L and a values increased and b values decreased. The sensory test showed that the hardness of Injulmi decreased, but springiness and adhesiveness increased by increasing ACW content to Injulmi. Overall Qualities of injulmi added with ACW up to 20% were similar to the non-added Injulmi.

Functional porperties such as CL, VP and EM did not affected by the addition of chitosans, however, level and MW of chitosans affected textural properties of LFSs, resulting in harder and springer texture of LFSs containing 0.3% MME chitosan as compared to others, Approximately 9 flavor compounds were different between RFC and LFS, and the addition of chitosans did not affected volatile compounds in the LFSs.

For the purpose of improving quality of defrosted-frozen chicken leg, beef and yellow corvina, the effects of height(0mm : H0, 5mm : H5, 10mm : H10, 15mm ; H15) for microwave defrosting on their physicochemical properties were investigated. In frozen chicken leg, color values were not significant different between each treatment while H10 and H15 had the highest score on appearance. Hardness of defrosted chicken leg was increased as height increased. In frozen beef, temperature of beef after defrosting increased as hight increase and H10 had the highest appearance score. In frozen yellow corvina, H10 had the highest hardness and appearance scores. Physicochemical properties of color, texture and appearance of microwave-defrosted frozen food were changed by height within microwave oven.

Effect of addition of oil , sucrose, dextrin and oil-sucrose (1 : 1 w/w) mixture on SPI tofu was investigated. The characteristics measured were yield , water holding capacity , textural and organoleptic properties. THe SPI tofufwas prepared by coagulation of soyprotein isolate (SP) suspensino by CaCl$_2$ , CaSo$_4$ an dGDL , followed by compression . Addition of oil to SPI increased the tofu yield and water holding capacity, particulary for those tofu coagulated by CaCl$_2$. Eventhough dextrin addition decreased the yield, it showed the most improving effect on water holding capacity. The tofu prepared by CaSO$_4$coagulant resulted highest in yield and water holding capacity. Hardness was found to be decreased as the oil, sucrose and dextrin added more and adhesiveness, cohesiveness and guminess were also affected. The sensory evaluation showed the SPI tofu prepared by CaSO$_4$ and 10% addition of oil and sucrose mixture to be realtively high in hardness , elasticity and uniformity of the texture.

This study was conducted to investigate the quality and antioxidant properties of white breads enhanced with broccoli powder (BP) (0%, 2.5%, 5.0%, 7.5% and 10.0%). L-value significantly decreased with increasing levels of BP, but a- and b-values increased (p<0.05). Baking loss rate, bread volume, and specific volume were reduced with the addition of BP, whereas the pH of the dough and bread weight increased. The hardness, gumminess and brittleness of breads with BP were higher than those of control breads (p<0.05). Upon sensory evaluation, the 2.5% and 5.0% BP breads showed no significant differences in color, flavor, taste, texture, or overall acceptability compared with controls (p<0.05). The 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity of bread significantly increased with increasing BP content (p<0.05). Accordingly, bread quality can be improved by the substitution of 5% BP in place of flour.

Solution-based MOD-TFA deposition technology of YBCO layers offers a route to low-cost YBCO coated conductors. Since the structures and properties of grown thin film by MOD process are strongly influenced by chemistry of precursor solution, the chemical modification of precursor solution for MOD process are important for improvement of the electrical properties of YBCO films. In this study, the precursor solution for MOD process are modified by chemical additives and solvents. The microstructure and texture of YBCO films grown by chemically modified precursor solution were characterized with SEM/EDS, XRD.

The objective of this study was to evaluate Toranbyung, according as the ingredients of Toranbyung were changed in various phases : firstly, mixing of taro with either rice flour or glutinous rice flour, and secondly, the amount of taro to be mixed with either rice flour or glutinous rice flour, The results were as follows; According to the sensory evaluation, Toranbyung made from glutinous rice flour and 4% taro ingredients met with the most favorable responses except flavor. In the case of Toranbyung made from rice flour, those made with 50% taro ingredients were most favored in taste, flavor, moisture, color, consistency and texture, With respect to the rheological properties of Toranbyung hardness, gumminess and springiness of Toraangyung made from glutinous rice flour were better. As the amount of taro increased, Toranbyung made from glutinous rice flour decreased in springiness, hardness, gumminess, and chewiness. As a result, Toranbyung made from glutinous rice flour and 40% taro ingredients and Toranbyung made from rice flour and 50% taro ingredients received the most favorable sensory evaluation.

Recently, the use of structure compound waterproof agent (hereinafter referred to as 'SCWA') that is used when manufacturing concrete for concrete structures, increases in quantity. However, while it is expected that the SCWA that is mixed in the concrete inside can significantly affect the change of physical properties that lift the internal force of a structure. This study has been conducted through an experiment for the effects of cement hardener on the formation of microscopic texture, and newly generated hydrates from that result were not confirmed in the. present experiment. It was found that at the hydrate reaction it has the property that can be hardened within the limit of pore diameterar a specific size rather than there is the internal gap filling capacity due to generating other hydrates.

Effects of compositions and sintering conditions on glaze properties are shown in the diagram constructed by using the unity molecular formula (UMF) method in this study. Glossy characteristics of glaze were clearly differentiated by compositional area in the diagram and sintering process. As alumina and silica contents were increased, texture of the glaze became rough and opaque, akin to having been devitrified or underfired. The correlation between glossiness and surface roughness was found to be non-linear and inversely proportionate. Crystalline phases formed in the glaze were also influenced by the compositional area. Due to the high concentration of CaO, anorthite and wollastonite were formed depending on the compositions. Hardness was increased with an increase of alumina and silica concentrations in the glaze.

In this paper we have extensively studied what and how processing parameters for quasi-carbonization influence the breaking strength and modulus of resulting quasi-carbon fabrics that are prepared from stabilized PAN fabrics with a spun yarn texture. Seven processing parameters have been considered as follows: applied tension, final heat-treatment temperature, heating rate, heating step, holding time, cooling rate, and purging gas purity. The results indicate that optimal uses of applied tension, final heat-treatment temperature, heating rate, and heating step during quasi-carbonization process are primarily important to increase the tensile properties of quasi-carbon fabrics and holding time, cooling rate, and purging gas purity are less importantly contributed.
