This study provides an eco-friendly dyeing processing for chitosan fiber using Oenothera odorata jacquin as a dye. The effects of chemical mordants (Al, Cu, Fe) and natural mordant (Chestnut shell) on the color change for dyed chitosan fibers were measured by K/S values, L, a*, b*, H, V, C values, color fastness, and antimicrobial activity. The results are as follows. Dyeing conditions of Oenothera odorata jacquin on chitosan fibers were optimized to 70℃, 30 minutes and 200% on weight of fabric (o.w.f.). The premordant concentration of aluminium (Al), copper (Cu) and iron (Fe) of chitosan fibers was optimized to 3% (o.w.f.) and 1% (o.w.f.), respectively. The post-mordant concentration of chemicals, such as Al, Cu and Fe, on chitosan was determined to 1% (o.w.f.). The hue of chitosan fibers by chemical mordants was measured to be reddish & yellow. The pre-mordant concentration of Chestnut shell of chitosan was optimized to 70% (o.w.f.). The post-mordant concentration of Chestnut shell on chitosan was determined to be 50% (o.w.f.). The hue of chitosan fibers by Chestnut shell mordant was measured to be reddish & yellow. The wet cleaning fastness of chitosan fibers was improved by a pre-mordant that used chemical mordants. In the case of the Chestnut shell mordant, the wet cleaning fastness was improved by a postmordant. The dry cleaning fastness of chitosan fibers was excellent regardless of mordants and mordant methods. The antimicrobial activity of the chitosan fiber was shown at 99.9% and its excellent qualities remained after the dyeing and mordant processing.

This study is to optimize the conditions for the treatment of polyamide fabrics using laccase. The pH, temperature, treatment time, and concentration were varied; their effects were evaluated by measuring the number of primary amide groups by the uptake of an acid dye measured by K/S of dyed polyamide fibers. The hydrophilicity of the fabrics was evaluated in terms of moisture regain and wettability. The effects of the mediator, ABTS, on the laccase activity were also evaluated. The optimal treatment conditions were identified as a pH of 4.5, temperature of 30oC, treatment time of 6 hours, and concentration of 10% of the weight of the fabric (o.w.f.). ABTS facilitated the activity of laccase on the polyamide fabrics. Voids and cracks on the surfaces of the laccase-treated polyamide fabrics were responsible for improved wettability. The results proved that laccase treatment improved the hydrophilicity of polyamide fibers without decreasing their strength.

This study examines the effects of Evening primrose on colors, color fastness, and the antimicrobial activity of dyed fabrics. The results are as follows. The dyeing conditions of Evening primrose on cotton and mercerized cotton were optimized at 50℃, 60 minutes, and 200% (o.w.f.). In addition, Evening primrose dyeing on silk was determined at 90℃, 60 minutes and 200% (o.w.f.). The pre-mordant concentration of chemicals of cotton, mercerized cotton and silk was optimized at 1% (o.w.f.). The post-mordant concentration on mercerized cotton, silk and cotton was determined at 1% (o.w.f.) and 3% (o.w.f.), respectively. The mordant methods (such as pre-mordant and post-mordant) were slightly affected on the hue of dye-fabrics. Wet cleaning fastness of cotton was improved by post-mordant; otherwise, the wet cleaning fastness of mercerized cotton and silk was improved by a pre-mordant. The dry cleaning fastness of cotton and silk was excellent regardless of mordant methods. The dry cleaning fastness of mercerized cotton was improved by a post-mordant compared to a pre-mordant. The antimicrobial activity of Evening primrose-dyed fabrics was shown at 99.9%. The excellent antimicrobial activity of dyed fabrics remained after the mordant as well as wet and dry cleaning.

건생강 제품의 진위판별을 위한 기초자료를 제공하기 위하여 건조된 생강으로부터 휘발성 향기성분을 추출하여 향기특성을 분석하고, MDGC/MS에 의해 키랄성 휘발성분의 enantiomeric composition을 분석하였다. 건생강에서 총 57종을 동정하였으며 주요 휘발성 향기성분은 zingiberene, β-sesquiphellandrene, β-bisabolene, (E,E)-α-farnesene 및 α-curcumene이었다. 건생강에 함유된 키랄성 향기성분 중에 서 enaniomeric composition을 측정하기 위해 선택된 키랄화합물 중 α-pinene 및 nerolidol은 높은 enantiomeric purity(>96%)로 검출되었으며, β-pinene은 (R)-enantiomer 만이 검출되어 특이적이었다. α-Terpineol은 (R)-enantiomer가 72%로 높게 나타났으며 linalool과 4-terpineol은 두 이성질체가 혼합된 것으로 나타났다. Limonene의 enantiomeric excess(ee, %)는 17.2%로 (S)-enantiomer가 주요 이성질체이었다. 따라서 이러한 키랄성 향기성분의 enantiomeric composition은 건생강의 진위평가를 위한 변수로 사용될 수 있을 것으로 생각된다. The volatile compounds of Zingiber officinale Roscoe were extracted by simultaneous steam distillation and extraction (SDE) method and identified with gas chromatography/mass spectrometer (GC/MS) analysis. Enantiomeric compositions of chiral compounds were determined by multidimensional gas chromatography/ mass spectrometer (MDGC/MS). A total of 57 compounds were identified and quantified, including zingiberene, β-sesquiphellandrene, β-bisabolene, (E,E)-α-farnesene and α-curcumene. Among them, zingiberene (38.41%) was found as the predominantly abundant component. α-Pinene and nerolidol in dried ginger were detected by high enantiomeric purity (>96%) for (S)-form, and β-pinene was detected only (R)-form. The enantiomeric composition of α-terpineol revealed 72.0% for (R)-form, and linalool and 4-terpineol showed mixtures of both enantiomers. (S)-Enantiomer was the major enantiomer of limonene having enatiomeric excess of 17.2%. Hence the enantiomeric composition of these compounds can be used as parameter for authenticity control of Zingiber officinale.

본 연구에서는 후지사과를 이용하여 천연향료를 개발하기 위한 기초자료로 활용하고자 추출방법에 따른 사과의 향기성분 특성을 비교하였다. SDE, 용매추출 및 SPME법으로 확인된 휘발성 향기성분은 각각 총 66, 32 및 54종이었으며, 주요 휘발성 향기성분으로는 (E,E)- α-farnesene, butanol, hexanol, 2-methyl butanol, hexyl hexanoate, hexyl 2-methyl butanoate, hexyl butanoate 등으로 사과의 특징적인 향기성분을 확인하였다. SDE법과 용매추출법에 의해 추출된 향기성분의 주요 화합물은 alcohol류와 hydrocarbon류로 나타났고, SPME법에 의해 추출된 향기성분의 주요화합물은 ester류와 hydrocarbon류로 상이하게 나타났다. 각 방법에 따라 추출된 휘발성 향기성분의 함량은 21.78, 7.48 및 11.67 ㎎/㎏으로 SDE법에 의해 가장 많은 향기성분이 추출되었으나 신선한 사과의 향기특성을 살리기 위해서는 SPME방법과 동일한 향기조성을 나타낼 수 있는 추출방법이 필요할 것으로 생각된다. The characteristics of volatile flavor compounds of Fuji apples were compared by different extraction methods for information leading to a natural fragrance development. The volatile flavor components of Fuji apples were extracted using simultaneous steam distillation and extraction (SDE), solvent extraction (SE), and solid-phase microextraction (SPME) methods and then analyzed by gas chromatograph-mass spectrometer. A total of 66, 32 and 54 components were identified in SDE, SE and SPME extracts, respectively. (E,E)-α-Farnesene, hexanol, butanol, 2-methyl butanol, hexyl hexanoate, hexyl 2-methyl butanoate, hexyl butanoate, and butyl hexanoate were the major flavor components in the extracts by different methods, but the composition of volatiles in the extracts were different. Alcohols and hydrocarbons were the major functional groups in SDE and SE extract whereas esters and hydrocarbons were the major functional groups in SPME extracts. SPME was the most suitable method for analysis of fresh volatiles from Fuji apples.

This study aimed to identify mordant effects of Chestnut hulls. The color of post and pre-mordanted fabrics were measured in terms of H, V, C, L*, a*, b*, and K/S values. In addition, color fastness and antimicrobial activity were evaluated. The pre-mordant concentration of Chestnut hulls for cotton, mercerized cotton and silk was optimized to 50% (o.w.f) and 70% (o.w.f), respectively. Post-mordant concentration of Chestnut hulls of mercerized cotton, silk and cotton was optimized to 50% (o.w.f.) and 90% (o.w.f), respectively. The hue of fabrics was influenced by mordant methods, such as pre-mordant and post-mordant, slightly. Wet cleaning fastness of pre-mordanted cotton and mercerized cotton fabrics was higher than that of post-mordanted fabrics. The wet cleaning fastness of silk fabrics was not affected by the mordant method, and their fastness were proved to be excellent. The dry cleaning fastness of post-mordanted cotton fabrics was higher than that of pre-mordanted cotton fabrics. The dry cleaning fastness of mercerized cotton and silk was proved to be excellent regardless of mordant methods. The antimicrobial activity of Oenothera odorata jacquin dyed fabrics and Chestnut hulls mordanted fabrics was proved to 99.9%, and their excellent antimicrobial activity remained after wet and dry cleaning.
