  • Processed meatball products were packaged in a passive package without oxygen scavenger as 1 control and 3 active packages of which have PP-based oxygen scavenger master batch materials (OSMB) of 40, 80, and 100%(w/w) in the middle layer and stored at 23 and $30^{\circ}C$ up to 9 months. Quality changes of packaged products were evaluated by measuring the oxygen concentration of the headspace in containers, thiobarbituric acid (TBA), color, and flavor. The oxygen concentration of the package having 100% OSMB was lower than those of 40 and 80%. The color changes and TBA values of the meat ball in the package containing 100% OSMB were the least among the treatments. Using principal component analysis (PCA), the control showed more flavor change than the packages containing oxygen scavenger. As a result, all active packages could extend the shelf life of the meatball products compared with that of the passive package.

  • Electronic-nose system was used to discriminate commercial sesame oils (A-F) extracted from imported seeds. Response (delta $R_{gas}/R_{air}$) of sensors gained from electronic nose was analyzed by principal component analysis (PCA). Flavor pattern of sesame oil A was similar to those of sesame oils B, C, and D. Sesame oils blended with corn oil at the ratio of 95:5, 90:10 and 80:20% (sesame oil/corn oil, w/w) could be discriminated from ouch genuine sesame oil.

  • This study was performed to suggest concentration methods leading to the production ofhoney with an excellent flavor by examining the effects of the concentration temperature and method on changes in 5-hydroxymethyl-2-furaldehyde (5-HMF) levels and the flavor components of honey. The 5-HMF contents of honey samples concentrated in a tray concentrator at 45, 50, 60, and 70℃ were 2.1, 2.3, 2.5, and 3.1 mg·kg-1, respectively, demonstrating that the 5-HMF contents increased as the concentration temperatures were increased. The honey vacuum-concentrated at 70℃ showed a higher 5-HMF content than that at 60℃, similar to the tray-concentrated honey at different temperatures. The main and other minor flavor components of the honey were volatilized and significantly reduced after vacuum concentration. In the tray concentration, all of the honey samples concentrated at 40, 50, 60, and 70℃ showed flavor component patterns similar to each other, and most of the main and other minor flavor components in the honey were volatilized and significantly reduced after tray concentration. As such, most of the main and other minor flavor components of the honey were mostly removed at 70℃ after both the vacuum concentration and tray concentration processes. The effects of the concentration method and temperature on the viscosity, 5-HMF level, and flavor components of the honey were found to be significant in this study. Given that the components of honey were shown to undergo significant physicochemical changes depending on the concentration method used and temperature during laboratory-scale production, the concentration methods devised in this study can be applied industrially.

  • The changes of the color, texture and volatile flavor compounds of Yu-gwa were investigated that affected by the oxidation during storage to characteristic Yu-gwa quality. Among the proximate compositions, carbohydrate was the most abundant component, and followed by lipid and moisture. Although the change of the color showed different pattern by the packaging materials during the storage period, the value of yellowness(b) increased but that of lightness(L) decreased dramatically after 3 month storage. In the textural properties reported closely related with the moisture content, hardness was fairly affected on the period of the storage rather than the type of packaging materials. The flavor compounds of Yu-gwa were analyzed to evaluate the change of distinct volatile compounds during storage. Of the twenty one separated volatile compounds, major volatiles were aldehydes, alcohols and alkenes. The results also showed that polyethylene(PE) contained less volatiles than polypropylene(PP) by the oxidation process during storage.2,4-Decadienal was gradually increased with the period of the storage, whereas octane and furan were decreased. The results provided that the change of the flavor distribution during the storage, and also the possibility of the volatiles such as hexanal, nonanal and 2,4-decadienal as the indicator for the oxidation process.

  • 대파를 부위별로 분획하여 대파 전체, 잎, 줄기, 뿌리를 동량 처리하여 각각 autoclaving법에 의하여 대두유를 기질로 WOSO를 제조하였다. 이들 4종 WOSO의 이화학적 특성은 큰 차이가 없었으며, 대파 잎향미유의 경우 Lovibond 색상에서 고유의 청색을 상대적으로 강하게 나타내는 특성을 나타내었다. 휘발성 향기성분은 총 35종이 검출되었으며, 주요 향기성분은 methyl propenyl trisulfide와 propenyl propyl trisulfide이었으며, 각각 대파 뿌리향미유에서 가장 높은 26.94 ppm, 26.26 ppm으로 나타났다. 이와 함께 propenyl propyl disulfide 등이 WOSO의 향미특성에 큰 영향을 미치는 성분인 것으로 판단된다. 또한, carbonyl 화합물 함량은 각각 79.46 ${\mu}g$, 77.17 ${\mu}g$, 76.32 ${\mu}g$, 73. 62 ${\mu}g$이었다. 결론적으로 WOSO에서 고유의 구수한 향미를 나타내는 부위는 잎이나 줄기가 아니라 뿌리 부분임을 확인할 수 있었다.

  • 품종에 따른 포도를 이용하여 3일 동안 $4^{\circ}C$와 실온에 각각 저장함에 따라 변화하는 전체적인 향의 패턴을 전자코를 통하여 분석하였고 SPME-GC/MS 분석 결과를 통하여 휘발성분을 분리 동정하였다. 대표적인 포도의 주요 휘발 성분은 alcohols, esters, acids, terpenes 등으로 GC/MS 분석 결과 butanoic acid/ethyl ester와 1-hexanol, hexanoic acid/ethyl ester, phenylethyl alcohol 등이 주요 성분으로 동정되었다. 캠벨은 다른 품종에 비해 다양한 휘발 성분이 동정되었고 레드글로브와 머루 품종에서는 1-hexanol, 2-decene, 8-methyl-(z)/1-dodecanol 등을 제외한 나머지 휘발 성분은 거의 나타나지 않았다. 또한 전자코를 이용하여 휘발성 향기성분 패턴 분석결과 $4^{\circ}C$와 실온 저장한 시료의 제 1주성분 값의 기여율은 각각 99.30, 99.36%로 품종에 따라 구분이 가능하였다. $4^{\circ}C$ 저장 시 저장 기간에 따른 제 1주성분 값의 변화 범위는 실온에서 저장한 것에 비해 적었음을 확인할 수 있었다.

  • This study evaluated the sensory characteristics of sauerkraut prepared by adding 0.5, 1.0, 1.5, 2.0, and 2.5% (w/w) sea salt to cabbage. The quantitative descriptive analysis (QDA) and acceptance test of sauerkraut were determined for each salt concentration, and the principal component analysis (PCA) and partial least square regression (PLSR) analysis were performed to confirm the correlation between each factor. Results of the QDA determined 14 descriptive terms; furthermore, brightness and yellowness of appearance and the sour, salty, and bitter flavors differed significantly according to the salt concentration. Results from the PCA explained 22.56% PC1 and 65.34% PC2 of the total variation obtained. Sauerkraut prepared using 0.5, 1.0, and 1.5% sea salt had high brightness, moistness, sour odor, green odor, sour flavor, carbonation, hardness, chewiness, and crispness, whereas sauerkraut prepared with 2.0 and 2.5% sea salt had high yellowness, glossiness, salty flavor, sweet flavor, and bitter flavor. Hierarchical cluster analysis classified the products into two clusters: sauerkraut of 0.5, 1.0, and 1.5%, and sauerkraut of 2.0 and 2.5%. Results of PLSR determined that sauerkraut of 1.0 and 1.5% were the closest to texture, taste, and overall acceptance. We, therefore, conclude that sauerkrauts prepared using 1.0 and 1.5% sea salt have excellent characteristics in appearance, taste, and texture.

  • The volatile flavor components of Zanthoxylum pipperitum A.P. DC. produced in Korea and China were isolated using a Clevenger-type apparatus by steam distillation extraction, and analyzed by gas chromatography-mass spectrometry (GC/MS). The yields of oils from Korean and Chinese Z. pipperitum A.P. DC. were 2.0 and 1.2% (w/w), respectively. From the two Z. pipperitum A.P. DC. oils, sixty and fifty-four volatile flavor compounds were tentatively identified, and they constituted 94.78 and 87.34% of the total peak area, respectively. Piperitone(p-menth-1-en-3-one) (13.48%) was the most abundant compound in the Chinese Zanthoxylum pipperitum A.P. DC. oil, followed by $\beta$-phellandrene, sabinene, terpinen-4-ol and linalool (each >5%). Whereas, the most abundant compound in the Korean Zanthoxylum pipperitum A.P. DC. oil was limonene (18.04%), followed by geranyl acetate, cryptone, citronellal, cuminal and phellandral (each >5%).
