  • Four kinds of natural dying solutions (natural colorant extracts)were obtained by extraction from sappan wood, black tea, peony, and clove using water as extracting solvent at $90^{\circ}C$ for 90 min with liquor ratio (solid natural colorant material/solvent water, weight ratio) of 1/10. The dyeing, colour fastness and deodorizing properties of fabrics (cotton, silk, and wool fabrics) dyed with natural colorant extracts were compared. It was found that these properties were significantly dependent on the concentration of extracts, the structure of colorant, and the kind of fabrics. The K/S value of dyed cotton fabric increased in the order of peony < sappan wood < clove < black tea, however, the values of dyed silk and wool fabrics were in the order of peony < sappan wood < black tea < clove. Colour fastness (light, water, and perspiration fastness) was in the range of 3 - 5 grade except for sappan wood. The deodorizing performance of fabrics dyed with various natural colorants extracts was in the range of 56 - 99%. The deodorizing performance increased in the order of peony < black tea < sappan wood < clove. Especially, the deodorizing performance of all fabrics dyed with clove was found to be the highest at 98-99%.

  • We carried out separation and guantitation of flavor components by GC about essential oils extracted from deodorized corn oil at the different deodorizing temperature. Flavor components were detected total 16 kinds included aldehydes of 8 kinds, major components were propane, pentane, hexanal etc. These major components content was about 70~75% of the total flavor components. According to rise of deodorizing temperature, both ethane and aldehydes of 8 kinds content were in proportion to increase, but propane, pentane, hexane, octan, pentyl furan content were decreased by contraries, respectively. On the other hand, total flavor component content was appeared the lowest level at 245$^{\circ}C$ treating group, aldehydes content was in proportion to increase according to rise of deodorizing temperature. These phenomenons consider that the undesirable reactions such as partial auto-oxidation, degradation, polymerization and hydrolysis etc. by effecting factors of stripping steam and vacuum degree. Conclusively, deodorizing temperature under high temperature was undesirable for the minimization of off-flavor materials.

  • The enzyme-like catalytic functions of metal complex phthalocyanine derivatives those containing carboxylic acid groups could be applied as odor-removing systems and antibacterial systems. Pyromellitic dianhydride and 4-nitrophthalimide were used as starting material for synthesizing dinitro-tetracarboxylic acid iron phthalocyanine(compound 1). Then diamino-tetracarboxylic phthalocyanine(compound 2) was obtained by reduction of compound 1. For the formation of covalent bond with cellulose fiber, cyanuric chloride was introduced to the amino group of compound 2 by condensation reaction compound 3. The exhaustion method was employed for adsorbing compound 3 on cotton fiber. K/S values of each fabrics were measured by a CCM system and deodorizing rates were tested by a detector tube method for ammonia gas. K/S values of treated cotton fiber with compound 3 were arranged from 2.1 to 4.2 at $90^{\circ}C$ of exhaustion temperature. Deodorizing rates provided result of 81%, 84%, 88%, 91%, by passing time of 30 min, 60 min, 90 min, 120 min, respectively.

  • Soybean oil (SBO) was carried out deodorization at 4 factors as controlled maximum deodorizing temperature (DT), vacuum degree (VD), cycle time (CT) and treating amount of stripping steam (TASS). The results were as follows, acid value (AV), peroxide value (PV) and trans fatty acid content (TFAC) in produced deodorized SBO. Obtained deodorized SBO at high DT had the lower AV, PV, but TFAC was increased relatively. A suitable level of VD and TASS was 4.0 torr and 2.0%(w/w), than the longer CT was appeared a superior quality level. As a result, the best deodorizing conditions in SBO for lower TFAC were maximum DT; $235^{\circ}C$, VD;4.0torr, CT; $14{\sim}15min$ and TASS; 2.0% (w/w). Deodorizing conditions for lower TFAC in deodorizing of SBO was the major factor, more than lower DT was difficult because of the others quality factors.

  • A study was conducted to investigate the effects of deodorizing temperature on physicochemical characteristics, fatty acid and triglyceride (TG) composition, and to estabilish the optimal deodorizing conditions in corn oil. Acid value (AV) of $240^{\circ}C$ treating group was showed 0.065 as the lowest level, the AV range was $0.08{\sim}0.09$ at $250{\sim}270^{\circ}C$. Lovibond total color was 24 as the lowest level, peroxide values (POV) were zero at $240{\sim}270^{\circ}C$ range. But POV was showed 0.42 meg/kg oil at $235^{\circ}C$, according to the optimal deodorizing temperature for the complete removal of peroxides was required more than $240^{\circ}C$. On the other hand, inclose of deodorizing temperature was conducted to the increase of saturated fatty acid content as myristic, palmitic, stearic and arachidic acid etc. Change of TG composition at treated group more than $250^{\circ}C$ was reliable, $S_3$ type TG was appeared. As a result, high temperature deodorizing was induced the undesirable influence at the physicochemical properties in deodorized corn oil.

  • This study shows the colorfastness, antibacterial activity, and deodorizing effect about cotton and silk fabrics dyed with Lithospermi Radix Extract. In the case of colorfastness, the light colorfastness showed the lowest grade, the other colorfastness was relatively good. However there are some differences according to fabrics and mordants. In the case of antibacterial activity to Staphylococcus aureus, the cotton fabrics had the most antibacterial effect at the dyed fabrics that had been mordanted SnC1$_2$ㆍ2$H_2O$, and the silk fabrics had the most antibacterial effect at the dyed fabrics that had been mordanted A1($CH_3$COO)$_3$. In the case of deodorizing effect, the cotton fabrics showed the most deodorizing effect at the dyed fabrics that had been mordanted SnC1$_2$ㆍ2$H_2O$, and the silk fabrics showed the comparatively high antibacterial effect at the dyed fabrics that had been mordanted both SnCl$_2$ㆍ2$H_2O$ and Al($CH_3$COO)$_3$.

  • It was determined to effects on cold test(CT) and smoke point (SP) of deodorizing temperature(DT) in corn oil. Increase of DT was induced to decrease of CT in deodorized oil, which was against the winterized oil inleted. Especially, the decrease of CT in deodorized oil was sharply at more than 26$0^{\circ}C$, this phenomenon was supposed to according the increase of total saturation degree as well as SU2, S2U, and S3 type triglyceride content. On the other hand, SP was showed the highest value as 242$^{\circ}C$ at DT as 24$0^{\circ}C$, the value was decreased to 235~238$^{\circ}C$ at DT as 245~27$0^{\circ}C$. This phenomenon was appeared in inverse proportion to the acid value of sample oils. Accordingly, high temperature deodorizing proved to be a very undesirable effect between general physicochemical characteristics, fatty acid composition and CT, SP etc.

  • Objectives: The aim of this study was to investigate deodorizing effectsof medicinal herbs (Mume Fructus, Eriobotryae Folium, Acanthopanacis Cortex, Angelicae Dahuricae Radix) for development of a gargle solution. Methods: 1. The antimicrobial effects of medicinal herbs were evaluated with the minimal bactericidal concentration (MBC) and the change of the number of viable cells in the herb extracts(1%) for 48 hrs against P. gingivalis 2561 and Pr. intermedia ATCC 25611. 2. Deodorizing activity of each herb and Garglin $Mint^{(R)}$gainst methyl mercaptan were analyzed by gas chromatography (GC). 3. We used the malodor modeling of the salivary sediment system with a Halimeter. 4. In the preliminary clinical study, the baseline concentration of VSC in the oral cavity of each subject was measured by Halimeter. Subjects would gargle for 30 seconds with cysteine. After 4 minutes subjects would gargle for 30 seconds with Garglin and herb extracts (2%). Subsequently, concentration of VSC were measured at 0, 4, 8, 12 and 20 minutes. Results: 1. MBC of Mume Fructusfor P. gingivalis 2561 was determined to be <1% and MBCs of Eriobotryae Folium for P. gingivalis 2561 and Pr. intermedia ATCC 25611 were determined to be <2% and <1%, respectively. Mume Fructus (1%) completely suppressed the P. gingivalis cell viability from 5 hrs and Eriobotryae Folium (1%) completely suppressed the Pr. intermedia cell viability from 48 hrs. 2. In GC analysis, deodorizing activities were 91.54% with Mume Fructus, 87.97% with Eriobotryae Folium, 100% with Acanthopanacis Cortex, 72.36% with Angelicae Dahuricae Radix and 40.54% with Garglin $Mint^{(R)}$. 3. In malodor modeling of the salivary sediment system, each of the medicinal herbs had significantly inhibitory effect on malodor formation (p<0.05). 4. In the preliminary clinical study, the concentration of VSC of the herb groups was significantly lower than of the control group, but not in Garglin $Mint^{(R)}$. Conclusions: Mume Fructus, Eriobotryae Folium, Acanthopanacis Cortex and Angelicae Dahuricae Radixhave deodorizing activities and potential as an effective mouthwash against oral malodor.
