매실주의 숙성 중 에틸카바메이트의 발생을 알아보고자 일반 가정에서 담그는 방식으로 매실주와 복분자주를 담아 저장하면서 발생량을 측정하였다. 매실주는 매실과 ㅅㄹ탕 및 19.5°~35°담금주의 담금비를 달리하여 담아, 15일부터 180일까지 15~30일 간격으로 에틸카바메이트의 함량을 분석한 결과 숙성 90일까지 매실을 설탕만으로 숙성한 경우와 복분자주에서 에틸카바메이트는 발생하지 않았으나 매실의 알코올의 농도가 높을수록 에틸카바메이트의 생성량이 증가하였다. 매실과 담금주의 비율을 달리한 결과, 매실보다는 알코올 함량이 에틸카바메이트 발생에 더 큰 영향을 미치는 것을 확인하였으며 120~150일 숙성기간이 지나면 서 에틸카바메이트 발생량은 점차 감소하는 경향을 보였으나 90일 숙성 후 여과처리 하였을 경우 여과하지 않았을 경우보다 180일까지 2배가량 높은 에틸카바메이트가 발생하였으나 이들 모두 안전한 수준이었다. This study was designed to investigate the formation of ethyl carbamate (EC) during the ripening of Maesil with sugar and Soju (19.5~35%alcoho contents) using a homemade method. Maesil, sugar and Soju were purchased at ordinary market in June of 2012. The preparation of sample for analysis was conducted by method of Henry et al. The analysis of GC/MS was used SIM mode (m/z 89, 74, 62). Quantification was performed in terms of the 62 ion and was based on an intermal standard procedure. Good linearity was obtained with a regression coefficient (r² = 0.993). Low detection limits (LOD) was achieved 4.31 ug/kg and recovery for alcohol was 74.8%. During 90days, fermentation with sugar was not detected EC (under LOQ). 15 days ripened Maesil wine contained EC between non detected~32.7 ug/kg and 90 days ripened Maesil wine was 19.7~87.4 ug/kg. Higher proportion of Maesil and Soju increased EC contents. EC levels were increased 32.7 ug/kg to 87.4 ug/kg in the ratio of Maesil to 35% alcohol-Soju (1:1). In the ratio of Maesil to 35% alcohol-Soju (1:3) was increased non detected to 69.7 ug/kg. After 90 days, Maesil wine was filtered Maesil through a seive and ripened by 180 days to investigate the formation of EC compared with non filtered. Treatment of filtered, EC contents was much higher level compared with non filtered. Therefore, this result showed that alcohol contents contribute to increase EC formation more than Maesil.

본 연구는 LC-MS/MS를 이용해 다소비 채소류 및 서류에 함유된 9종의 chlorogenic acid 이성질체를 분석하기 위하여 시료 추출 후 QuEChERS kit으로 정제하는 전처리법을 확립하였고, Syncronis C18 컬럼을 사용하여 30분 동안 분석하는 이동상 용매 조성과 9종의 이성질체의 정량 및 정성 이온을 선택하여 negative 모드에서 분석하는 기기 분석법을 확립하였다. 확립한 분석법은 AOAC 가이드라인에 따라 특이성, 직선성, 검출한계, 정량한계, 정확성, 정밀성을 확인하여 유효성을 검증하였다. 다소비 채소류 및 서류 43품목(48품종)의 chlorogenic acids 함량을 분석한 결과, 24품목(29품종)에 함유되었음을 확인하였다. 채소류의 경우 39품목(42품종) 중 22품목(25품종)에 chlorogenic acids가 함유되었으며(0.01±0.01~38.31±8.73 ㎎/100 g FW), 취나물, 케일, 미나리, 우엉, 상추, 브로콜리, 콜리플라워, 가지, 치커리, 도라지 순으로 함량이 높게 나타났다. 서류는 고구마(호박고구마, 밤고구마), 감자(로즈밸리, 수미), 마, 토란 등 4품목(6품종)을 분석하였는데, 고구마의 경우 밤고구마(1.31±0.52 ㎎/100 g FW)보다 호박고구마(1.42±0.39 ㎎/100 g FW)에, 감자의 경우 수미(0.09±0.03 ㎎/100 g FW)보다 로즈밸리(0.37±0.07 ㎎/100 g FW)에 chlorogenic acids 함량이 높게 나타났다. 또한 취나물, 미나리, 고구마, 감자를 대상으로 조리시간에 따른 chlorogenic acids 함량 변화를 확인한 결과, 취나물과 미나리는 30초 삶았을 때 가장 높은 함량을 나타내었고, 감자는 30분, 고구마는 20분쪘을 때 chlorogenic acids 함량이 높게 나타났다. 본 연구에서는 다소비 채소류 및 서류의 chlorogenic acids 함량과 조리시간에 따른 chlorogenic acids 함량 변화를 확인하여 식품 내 chlorogenic acids 함량에 관한 기초자료로 제공하고자 하였다. In this study, a sample preparation method and simultaneous determination method were developed to determine the chlorogenic acids content of frequently consumed vegetables, root and tuber crops in Korea by liquid chromatography coupled to mass spectrometry. The developed method was validated for its specificity, linearity, limit of detection, limit of quantification, recovery, accuracy, and precision based on the AOAC guidelines. Among the 39 items of vegetables, 22 items (0.01±0.01∼38.31±8.73 ㎎/100 g fresh weight (FW)) were quantified. The chlorogenic acids content of the vegetables was in the following order: chwinamul (38.31±8.73 ㎎/100 g FW), kale (22.93±0.75 ㎎/100 g FW), water dropwort (10.67±4.46 ㎎/100 g FW), burdock root (9.72±2.52 ㎎/100 g FW), red lettuce (leaf) (8.66±5.37 ㎎/100 g FW), broccoli (2.45±0.50 ㎎/100 g FW), and cauliflower (2.35±0.36 ㎎/100 g FW). Among the four items of root and tuber crops, sweet potato (1.42±0.39 ㎎/100 g FW) and potato (0.37±0.07 ㎎/100 g FW) were quantified. In addition, the chlorogenic acids content of chwinamul and water dropwort was highest when boiled for 30 seconds. Sweet potato steamed for 20 minutes and potato steamed for 30 minutes showed high chlorogenic acids contents.

식용유지 중의 산화방지제를 효율적으로 분석하기 위하여 일반적인 용매추출법과 SCD법으로 전처리하여 HPLC법으로 비교 분석하였다. SCD법의 최적조건은 florisil의 활성도와 UNITREX의 온도와 추출시간에 따른 회수율로 분석하였다. 식용유지에 산화방지제를 농도별로 가하여 용매추출법과 SCD법의 회수율을 비교한 결과 용매추출법은 80.4∼102.1%, SCD법은 89.8∼106.4%로 나타났다. Florisil의 활성화에 따르면 2% 수분 첨가시 TBHQ, BHA, BHT는 89.8∼106.4%로 회수율이 가장 높았고, PG는 5% 수분 첨가시 53.9±7.3%의 회수율을 보였다. 회수율은 UNITREX의 210℃에서 20분간 추출하였을 때 가장 높았다. This study was conducted to evaluate the extraction methods for the determination of antioxidants in soybean oil. Recovery rates of various antioxidants in soybean oil showed similar rates as 80.4∼102.1% by solvent/solvent extraction method and 89.8∼106.4% by sweep co-distillation method except 46.6∼61.2% of PG at corresponding spiked concentractions. The maximum recovery rates of antioxidants were obtained when extraction time and extraction temperature used in UNITREX were 20min and 210℃ respectively. In the recovery rates with the activation of florisil, when 2% of water was added to florisil, the highest recovery rates for TBHQ, BHA, BHT were obtained by sweep co-distillation method. Therefore, sweep co-distillation method showed less solvent, simple operation and high recovery rate compared with solvent/solvent extraction method.
