  • Methods for the development of home meal replacement seafood tailored to consumer needs for the advanced use of Broughton's ribbed ark Scapharca broughtonii (BRA) in Korea are required. In this study, we developed a cheese-topped, semi-dried, and seasoned Broughton's ribbed ark (S-BRA) tailored for the younger generation with an improved texture and fish odor. The optimization of conditions to improve the texture and fish odor was performed using RSM. The design of the model was appropriate because there was no significant difference (P>0.05) between the predicted and actual values of moisture content, hardness, and overall acceptance, and the optimal preparation conditions were a vinegar content of 2.68%, a soaking time of 62 min, a drying temperature of 60℃, and a time of 162 min. The S-BRA manufactured under these optimal conditions exhibited a lower odor intensity compared to the unsoaked and undried control, suggesting that the fish odor of S-BRA has been improved. The moisture content related to the texture of the S-BRA was lower than that of the control, and the hardness was higher. Therefore, the S-BRA developed in this study will appeal to people of all ages, especially the younger generation; their consumption is expected to increase.

  • This study was carried out to investigate the quality of white pan breads as affected by various amounts of Terminalia chebula Retz (TC) powder, in which the breads were prepared with 0, 2, 4, and 6% TC powder. The samples and a control bread were compared in terms of bread quality characteristics, including pH, baking loss rate, loaf volume index, moisture content, TBARS values, texture, color, and sensory qualities in order to determine the optimal amount of TC powder in the formulation. The pH levels of the bread samples containing TC powder ranged from 5.30 to 5.44, while the control bread had a pH of 5.68. The loaf volume index values of the samples prepared with 2~6% TC powder were lower than that of the control. After 7 days storage, the moisture content of the control bread had decreased by 14.4%, while the moisture contents of the breads with added TC powder had decreased by approximately 8~10%. The breads with TC powder had lower TBARS values as compared to the control bread. For texture characteristics, hardness increased with the addition of TC powder, and was especially increased in the sample containing 6% TC powder. Cohesiveness and springiness, however, decreased with the addition of TC powder. For color, lightness of the bread crust and crumb decreased with the addition of TC powder, whereas redness and yellowness increased. In terms of sensory quality, the bread containing 2% TC powder was preferred over the control bread, as estimated by appearance, crust color, taste, and overall quality, while the 6% TC bread had the lowest preference scores. These results suggest that the addition of 2% TC powder to white pan bread had optimal effects for improving shelf-life and enhancing bread quality.

  • Packages of different atmospheres (air (control), 100% CO2, vacuum, and vacuum + O2 absorber) were prepared for 0.4 kg rice cake (ddukgukdduk) using gas-barrier plastic film and stored at 10℃ for 11 days. The stored products were evaluated in their packages atmosphere, total aerobic bacteria, yeast and molds, texture and sensory quality during storage period. In the air package, the O2 concentration decreased from initial 21% to 16% on storage 4 days and the CO2 concentration increased to 23% on storage of 11 days, which resulted from the growth of microorganisms. CO2 concentration decreased from initial 98% to 36% on storage 11 days in the 100% CO2 package. It is reasoned that CO2 was dissolved into the product reducing the volume of the package. Vacuum and vacuum +O2 absorber package maintained shrunk vacuum condition until 11 days of storage. Total aerobic bacteria count increased significantly in the control package (6.41 log (cfu/g) after 11 days) compared to the 100% CO2 package (4.96 log (cfu/g) after 11 days). Yeast and molds were 6.66 in control package, 3.43 in 100% CO2 package, 4.66 in vacuum package, and 3.78 in vacuum + O2 absorber package after 11 days. There was no significant difference between control and the other treatments for the texture of the stored products. Sensory quality was the worst in control package on the storage of 8 days. All treatment groups except control improved the quality preservation, but vacuum and vacuum + O2 absorber packages suffered from cracking of the product. Thus 100% CO2 flushing is suggested as a desired packaging condition.

  • Green tea (Camellia sinensis L.) is consumed as a popular beverage worldwide, particularly in Asia. In this study, the effects of green tea powder addition on the antioxidant activities and texture properties of cooked rice were investigated. Texture analysis was carried out by texture profile analysis. Total polyphenols and total flavonoids were determined using spectrophotometric methods, and antioxidative activities were determined based on DPPH and ABTS radical scavenging activities, reducing power, and lipid peroxidation inhibitory activity. Antioxidant contents and antioxidative activities increased with a higher amount of green tea powder. However, there was no difference in texture properties between cooked rice with green tea powder and the control group. In conclusion, addition of green tea powder to cooked rice would be useful to increase antioxidant contents and antioxidative activities without alteration of texture properties.

  • Whitefish(Coregonus clupeaformis) and Burbot(Lota iota) muscle was filleted, treated with dipotassium phosphate(pH 8.0) by means of high pressure injection method, and finally stored at $-l2^{\circ}C$ for 3 months. Factors, the pH, moisture content, and total amount of collagen were analyzed on the samples before and after the frozen storage. The pH of the sample showed substantially higher values in the phosphate treated muscles than the controls and decreased after 3 months storage in all of the whitefish and burbot samples, there was no significant differences in the moisture content between the control and treated but some reduction occurred during frozen storage. The amount of total collagen in the tail sections of burbot was significantly high comparing with head sections and hardness of the tail section also showed high values which indicated that total collagen might be related to the texture of fish muscle. However, in the case of whitefish the effect was not apparent. The effects of these factors on the hardness determined by Instron texturometer were analyzed through standardized multiple regression. A specific factor was not apparent to the texture of white fish while pH showed the highest correlation to the hardness of the burbot muscle.

  • To improve the shelf-life of mushrooms, Lentinula edodes GNA01 mushrooms were treated with gel packs containing slow-released chlorine dioxide ($ClO_2$) gas at 5~10 ppm for 5 days at $20^{\circ}C$ and the weight loss rate as well as the changes in pH, color and texture properties of the treated samples were investigated. The weight of the control and $ClO_2$ gas treated samples were decreased slightly, and there were no differences during the storage period. However, the weight of the control changed faster than those of the $ClO_2$ gas treated samples during storage period. The pH in the control and in the $ClO_2$ gas treated samples were decreased during storage period, but the samples treated with 5 and 7 ppm $ClO_2$ gas were the least changed. On the other hand, the samples treated with 10 ppm $ClO_2$ gas showed no difference from the other treatments during 4 days, but the pH was lower than that of the control on the fifth day. The lightness of inside and outside in mushroom were decreased whereas redness and yellowness were increased during storage period. However, color changes in the $ClO_2$ gas treated samples were lower than those of the control. Especially, the samples treated with 5 and 7 ppm $ClO_2$ gas were the least changed. The texture of the mushroom were decreased consistently during storage period. The texture of the control changed faster than those of the $ClO_2$ gas treatments during 5 days. Especially, the samples treated 5 ppm $ClO_2$ gas were the least changed.

  • Press ham were manufactured to investigate the effects of ginseng powder on quality characteristics of press ham. Each treatments added pork loin basis with ginseng powder(0, 0.5, 1.0, 1.5 and $2.0\%$) were stored until 28 days at $4^{\circ}C$. The changes in physico-chemical properties, texture and chemical composition of each treatments were measured during 1, 7, 14, 21 and 28 days at $4^{\circ}C$. There was a not significantly difference in chemical composition between control and ginseng treatment groups. pH value of ginseng treatment groups were decreased significantly than those of control(p<0.05). pH of control and ginseng treatments were increased significantly as the storage period passed(p<0.05). Meat color(CIE $L^{\ast},\;b^{\ast}$) of ginseng treatment groups were increased significantly than that of control(p<0.05). Meat color(CIE $a^{\ast}$) of ginseng treatment groups were decreased significantly than those of control(p<0.05). It was not clearly changed by the passage of storage time. There was a not significantly difference in texture between control and ginseng treatment groups. It was not clearly changed by the passage of storage time. Summing up the a forementioned result, press ham manufacturing with ginseng powder was not affected in physico-chemical properties and texture characteristics. Also, it may be assumed that the high quality press ham can be manufactured with saponin accumulation.

  • An important signal processing problem in PVDF sensor is the restoration of surface information from electric sensing signals. The objectives of this research are to design a new texture sensing system and to develop a new signal processing algorithm for signals from the sensor to be tangibly displayed by tangible interface systems. The texture sensing system is designed to get surface information with high resolution and dynamic range. First, a PVDF sensor is made of piezoelectric polymer (polyvinylidene fluoride) strips molded in a silicon rubber and attached in a rigid cylinder body. The sensor is mounted to a scanning system for dynamic sensing. Secondly, a new signal processing algorithm is developed to restore surface information. The algorithm consists of the two-dimensional modeling of the sensor using an identification method and inverse filtering from sensing signals into estimated surface information. Finally the two-dimensional surface information can be experimentally reconstructed from sensing signals using the developed signal processing algorithm.

  • This study investigated the quality characteristics of jelly using sericultural products which were manufactured with various addition levels(0.5, 1, 1.5, 2%) of mulberry leaf powder. To establish the additional amount of mulberry leaf powder, physicochemical, sensory, and texture results were analyzed. The moisture and crude protein content of Pongnipjelly were higher than that of the control(p<0.05). The mineral content was increased with increasing addition levels of mulberry leaf powder. The color of Pongnipjelly darkened with increasing addition levels of mulberry leaf powder. As for the texture analyser, the hardness, gumminess, and chewiness increased with increasing addition of mulberry leaf powder(p<0.05), whereas the springiness decreased. Therefore, the optimal added amount of powder for the manufacture of Pongnipjelly was determined to be 1.5% of the total weight.

  • This paper deals with animation of snowy scenery using texture mapping and particle system. Two different OpenGL programs were prepared and compared for implementation and evaluation of their performance. One used glPointSize(), and the other used glut SoildSphere(). Result of implementation revealed that the first was faster than the second. So the first is considered to be more useful for the slow PC. In relation to the first method, I found that control of shape of snow flake conflicts with that of color. Fortunately, I found out an esoteric method which handles the back ground image for scene that is used in texture mapping, I present that method.
