  • The present study investigated the influence of different volumes of red hot pepper juice on the quality characteristics of fresh Pasta noodle. Supplementation with 0% (control), 2.5%, 5%, 7.5%, or 10% red hot pepper juice produced similar gelatinization characteristics of peak viscosity, temperature at peak viscosity, hot paste viscosity and numerical value of breakdown. However, increasing concentrations of red hot pepper juice produced progressively and significantly low cold paste viscosity and setback. The chromaticity of wet and cooked noodles was significantly lower in L value and significantly higher in +a and +b values with increasing volumes of red hot pepper juice. The texture of fresh noodles displayed no significant differences in hardness, adhesiveness and chewiness. The springiness and cohesiveness were lower and higher with the increase of added red hot pepper juice, respectively, but the differences just attained significance. For cooked noodles, adhesiveness, springiness, cohesiveness and chewiness tended to be higher with increasing volumes of red hot pepper juice, but again the differences just attained significance. Cooking characteristics of weight, volume, moisture absorptive power and turbidity decreased with increasing volumes of red hot pepper juice. Sensory characteristics of acceptability including appearance, color, flavor, taste, texture and overall-acceptability improved with increasing red hot pepper juice volume, in particular with 5% and 7.5%. Amylograph characteristics for initial paste temperature positively correlated with the texture characteristics for chewiness (p<0.05). Negatively correlated amylograph parameters included texture for springiness with for peak viscosity (p<0.01), texture for adhesiveness with hot paste viscosity (p<0.01) and breakdown with texture for adhesiveness, cohesiveness and chewiness (p<0.05).

  • Statement of problem: The clinical criteria of soft lining materials are resilience over an extended period, capability of forming a strong bond with denture base materials, dimensional stability, adequate tear strength, and color stability. Many researches and reports dealt with food colorants or denture cleanser, but not with fermented foods. Purpose : This study was designed to assess what fermented foods, such as soy sauce and red pepper paste that many Koreans have eaten, influence on the color stability of soft denture liners. Material and methods: The color differences (${\Delta}E^*$) were measured by spectrophotometer with different immersion time. For the procedure, thirty disk-shape specimens per 4 soft denture linears(Molloplast-$B^{(R)}$, Ufi Gel $SC^{(R)}$, Dura $Base^{(R)}$, Sofreliner $MS^{(R)}$) were fabricated with a thickness of 2mm and 16mm in diameter. Each 10 specimen were immersed into the beakers of fermented foods distilled water, and $L^*$, $a^*$, $b^*$ values were measured for the color difference(${\Delta}E^*$), on the 1st, 7th, and 28th day with spectrophotometer. Result and conclusion : 1. There were significant differences between samples(soy sauces, red pepper pastes, and distilled water) in Sofreliner $MS^{(R)}$ of 1st day after immersion(p<0.05). There were significant differences between samples in Sofieliner $MS^{(R)}$ and Ufi Gel $SC^{(R)}$ of 7th days after immersion(p<0.05). There were significant differences between samples in Molloplast-$B^{(R)}$ of 28th day after immers ion(p<0.05). 2. In red pepper pastes, ${\Delta}E^*$ values of Molloplast-$B^{(R)}$, Ufi Gel $SC^{(R)}$, Sofrelinev $MS^{(R)}$ weve higher than 3.3. Those values were not clinically acceptable. In soy sauces, ${\Delta}E^*$ values of all denture liners were lower than 3.3. ${\Delta}E^*$values of Ufi Gel $SC^{(R)}$ were higher than those of other denture liners 3. Based on the above results , red pepper paste causes more discoloration than soy sauce.

  • The effects of agents in padding liquor on the fixation of vinylsulfonyl reactive dye of ground color and on the resist-dischargeability in resist-discharge printing of cotton fabrics with reactive/reactive dyes were investigated. Alkalis, such as sodium bicarbonate, sodium carbonate, sodium acetate and trichloro sodium acetate, were used to fix the dye for ground color on cotton fabrics. Sodium bicarbonate and sodium carbonate showed a good fixation of the dye for ground color, but they were ineffective to the white and the colored resistdsichargeabilities, which were caused by the fast fixation of the dye for ground color before its reaction with resist agent in printing paste. Therefore these are not suitable for the agent to fix the dyes for ground color because they deteriorate the resist-dischargeability. In case of sodium acetate, as the fixation yield of the dye for ground color was remarkably low. and the white resistdischargeability was not good, it had better not be used for the agent to fix the dye for ground color. However, the addition of sodium trichloroacetate to padding liquor gave a very good fixation yield of ground color, and showed an excellent resist-dischargeability. The effects of acetic acid in padding liquor on the fixation of the dye for ground color and on the resist-dischargeability were studied in case of immediate printing of resist-discharge pastes after padding and drying and in cases of printing after 1∼3 day-storage of padded goods. By the addition of 2% of 48% acetic acid aqueous solution to padding liquor, the white and the colored resist-dischargeabilities were improved and the fixation of the dye for ground color was good without any troubles. Especially, when the padded goods were stored for 2 or 3 days and printed with resist-discharge printing pastes, its addition was very effective on the resist-dischargeability.

  • For the production of pumpkin paste with respect to heating conditions, we steamed the pumpkin for roughly 15 min, heated it with high pressure treatment for 0 min (A), 10 min (B), 20 min (C), 40 min (D), and subsequently investigated the quality characteristics. Generally a significant difference was observed between the pumpkin paste treated with and without high-pressure heat. The values of water content, crude protein and crude fiber of the high-pressure heat-treated groups B, C, D were decreased compared with untreated group A. The soluble fiber in experimental group B sweet-pumpkin paste treated with high-pressure heat for 20 min was higher than the control, and the highest value at 2.02. Experimental group D sweet-pumpkin paste treated with high-pressure heat for 40 min was found to have a decreased soluble fiber content relative to the control. The L value for the color of the group A untreated control sweet-pumpkin paste (no high-pressure heating) decreased as the time increased from 10 min to 40 min, with L values of 50.33, 49.46, and 48.06, respectively. The b value for the color of the sweet-pumpkin paste also decreased, showing a significant difference. Taking into account all the results, we chose experimental group B in order to prepare sweet-pumpkin latte. We used 0.2% gum (xanthan gum, locust bean gum, guar gum) as a stabilizer. Sweet-pumpkin latte with xanthan and locust bean gum has a suspension stability effect that lasts 90 min. The L and b values of sweet-pumpkin latte with gums increase and a value decrease compared with the control. In terms of the overall acceptance of the sweet-pumpkin latte, the experimental group with xanthan gum scored the best.

  • This study was performed to aid promotion of fish paste containing Lycii fructus powder as a food. The tested concentrations of Lycii fructus powder were 0, 1, 3, 5, and 7%. All the fish paste samples had 37% water content. The L values of the samples decreased as the concentration of Lycii fructus powder increased(p<0.001), and the a- and b-value increased(p<0.001). All samples with 3 mm of thickness had good flexibility and did not break even after four times of folding. In texture meter tests, the cohesiveness increased, but gumminess and brittleness decreased according to increasing concentration of Lycii fructus' powder. In the sensory evaluation, scores for color, flavor, pleasant taste, hardness and adhesiveness increased with increasing powder concentration; however oily taste was decreased. The 3% Lycii fructus powder sample had the highest acceptance scores in terms of appearance, flavor, taste, texture and overall acceptability. The results suggest that Lycii fructus powder can be applied to fish paste for both quality and functionality.

  • This study evaluated the quality characteristic of red pepper powders of Hanbando and Cheongyang cultivars by particle size. Two types of powder samples for pepper paste and Kimchi were prepared, and capsaicinoid contents, Hunter Lab color values, and ASTA values by particle size distribution were investigated. Particle size distribution was normal in the pepper paste powder; however, an abnormal distribution was shown for the Kimchi powder. In addition, the greatest particle sizes were $300{\sim}425\;{\mu}m$ in the pepper paste powder. In accordance with smaller particle size, redness (a-value), ASTA values, and capsaicinoid contents increased. Redness (a-value) by particle size was in the range of 15.13~31.34, and ASTA values were in the range of 53.35~96.87. Capsaicinoid contents by particle size were in the range of 1.90~6.05 mg/100 g for Hanbando and 156.65~235.10 mg/100 g for Cheongyang.

  • Alaska Pollack (Theragramma), Mackerel (Socomber japonicus), yellow corvenia (Pseudosc iance manchurica) were dressed, and then meat was separated from the other parts through a fish meat separator. After dehydration, the meat was ground with a silent cutter, packaged in polyethylene bags, and stored at -15。C for days. Samples were taken at regular intervals throughout the storage period and investigated for changes in puality characteristics such as the amounts of nitrogenous compounds, degree of lipid oxidation, fatty acid composition, and organoleptic factors. The resrlts obtained in this study were as follows; 1. The volatile basic nitrogen[VBN] contents of Alaska pollack, and yellow corvenia meat pastes increased from 14.4, 11.2 and 10.8mg% to 41.6, 38.3 and 40.6mg%, respectively during a 120 day storage period, whereas the trimethylamine oxide nitrogen [TMAO-N] contents decreased from 117.2, 12.8 and 17.2mg% to 40.3, 2.6 and 7.1mg% during the same period. 2. The TBA value of the mackerel meat paste showed a maximum peak after 60 days, and then decreased gradually, whereas the TBAvalues of the alaska pollack and yellow corvenia meat pastes increased steadily during the same period. The acid values of the meat pastes increased during the storage period, while the iodine values decreased. 3. The fatty acid composition of the total lipid of the meat pastes changed considerably during ghe 120 days storage period : saturated fatty acids in the total lipid such as myristic, palmitic, and stearic acid increased, while unsaturated fatty acids such as linoleic, gadoleic, eicosapentaenoic, erucic and docosahexaenoic acid decreased steadily. The initial percentage contents of the unsaturated fatty acids in the total lipid of the Alaska pollack, mackerel, and yellow corvenia meat pastes were 87.2%, 63.9%, and 75.9% respectively. However, the contents decreased to 46.0%, 42.5% and 51.3% after the 120day storage period. 4. The color of the meat pastes changde gradually into dark brown. L values of the meat paste measured with a thistimulus colorimeter decreased steadily during the storage period, while a and b values increased during same period. 5. Judging from the results of organoleptic evaluation on the fish odor, color and overall acceptability, significant difference were found between the odor and color of the mackerel and those of the yellow corvenia meat pastes. Overall acceptability score of yellow corvenia was higher than that of Alaska pollack or mackerel meat pastes.

  • Four volumes of the script of the Avatamska Sutra written with golden paste on dark blue papers manufactured in Koryo Dynasty which are collected or deposited in every museum of Japan show specific features on their cover paintings. In general 3 or 4 lotus flowers are wound by arabesque patterns in zigzag on the cover paintings of Koryo scripts, whereas 10 lotus flowers painted with golden paste on the 4 volumes of these scripts are same in their style. Though there is no prayer sentences in 4 volumes of the script, it is possible to know that they should belong to a set of 80 Avatamska Sutra by the results of above studies. In this study the contents of Byunsangwha of the script of 4 volumes of the Avatamska Sutra were discussed at first and their manufactured era should be postulated by the results of style analysis of cover paintings and Byunsangwha. First thing that saint hair of Buddha was painted with cobalt color is same as that of Byunsangwha of Munsuchoisangsungmusenggebueob prayed in Tejeong 3rd year, king Chungsuk 13th year(AD 1326). Second thing that the beads in topknot of saint hair and lips were painted completely with pink color, and ears, face outline as well as bosom outline disclosed through monk's cloth were also painted with pink color, furthermore the last thing is that Buddha's face was coated with golden paste. All of these things are same as shown in the characteristics of Byunsangwha of the scripts of Kanezawa Daishoji, Matsue Tenrinji and Haga Tera collection in Japan. However, since the cloud pattern style of Byunsangwha of the script is similar to that of the Byunsangwha manufactured in reinstatement era of king Chungsuk, it is possible to say that these 4 volumes of script should be manufactured in the reinstatement era of king Chungsuk.

  • We investigated the physical characteristics and changes in the functional components of red pepper paste, or gochujang, during fermentation at $20^{\circ}C$ for 90 days with different amounts of sweet persimmon powder. The viscosity of the paste decreased a little with increasing fermentation time. There was no significant difference (p<0.05) in all the treatments during fermentation. The L value, a value, and b value showed a tendency to gradually decrease with increasing fermentation time. And the samples with sweet persimmon powder showed a lower values compared to the control during fermentation. The phenolic compound content of the paste with sweet persimmon powder ranged from 13.72 mg% to 16.13 mg% at an early stage of fermentation, showing a significantly higher value (p<0.05) when increasing the amount of the powder. The content was in the range of 13.72~16.09 mg% on the 90th day in the final stage of fermentation, showing no significant difference (p<0.05) compared to those content at an initial stage of fermentation. The carotenoid content showed significantly higher values (p<0.05) when increasing the amount of sweet persimmon powder. In conclusion, sweet persimmon powder in the red pepper paste would gives a more functional effect which could be from bioactive components, such as phenolic compounds and carotenoids. But, it did not positively affect the color of the red pepper paste.

  • In this research, we manufactured the paste opaque porcelains using Propylene Glycol (PG) and Buthylene Glycol (BG) as a solvent, and compared the composition of solvents, the coefficient of thermal expansion, the particle size distribution, the viscosity and bonding strength to metal, and the tone with those of the commercial products(Duceram Plus, Duceram GmbH; VMK 95, Vita Co.; Noritake EX-3, Noritake Co.)used in the clinical field. The results of the research were as follows: 1. The result of solvent analysis indicated that the solvents included in the paste opaque porcelains of the control group were mainly composed of Glycols. 2. From the Coefficient of thermal expansion measurement, we drew out the following results; testing group: $14.0\times10^{-6}/^{\circ}C$, Duceram Plus: $13.9\times10^{-6}/^{\circ}C$, VMK 95: $14.3\times10^{-6}/^{\circ}C$, and Noritake EX-3: $13.3\times10^{-6}/^{\circ}C$. 3. Seen from the result of particle size distribution measurement, the experimental group was similar to the control group in 1$\mu m$ below, but the experimental group marked the highest distribution of 61% in the case of between 1$\mu m$ and 5$\mu m$. Between 5$\mu m$ and 10$\mu m$, they showed relatively similar distribution, and Noritake EX-3 was turned out the highest distribution of 29% in 10$\mu m$ above. 4. From the result of viscosity measurement, Duceram plus showed the highest viscosity throughout all the measurements followed by Noritake Ex-3, experimental group and VMK 95 in decreasing order. 5. The result of bonding strength measurement was EX 35.53 $\beta\acute{A}$, DU 40.88 $\beta\acute{A}$, VM 39.43 $\beta\acute{A}$, and NO 35.39 $\beta\acute{A}$, and no significant difference was found between the experimental group and the control groups(P>0.05). 6. The measurement of the tone indicated that the $L^*$ value of the experimental group was 86.89 0.63 in average, which is higher than the control group in its brightness. In the case of the $a^*$ value, Duceram Plus, VMK 95 and EX-3 showed positive value, whereas the testing group was turned out negative value. In $b^*$ value, Duceram Plus proved the highest. From the results of this research, the paste opaque porcelains using Propylene Glycol (PG) and Buthylene Glycol (BG) as a solvent did not make differences from the commercial products that are actually used in the clinical fields. Therefore, it is possible to utilize Propylene Glycol (PG) and Buthylene Glycol (BG) for the paste opaque porcelains of P.F.M crown. It is also recommended that further researches concerning the compositions and forms of powder, the types of organic solvent components and the ratio of mixture proceeded in order to improve the level of productivity in the future.
