Abstract

This study was aimed at investigating the levels of the natural preservatives of benzoic, sorbic and propionic acids in cereal grains, nuts and seeds. Benzoic and sorbic acid were analyzed by high-performance liquid chromatography with a diode-array detector (HPLC-DAD) and further confirmed by liquid chromatography-tandem mass spectrometry (LC-MS/MS), whereas propionic acid was analyzed using a gas chromatography-flame ionization detector (GC-FID) and further confirmed by gas chromatography-mass spectrometry (GC-MS). Benzoic, sorbic and propionic acids were found in 44, 22, and 550 samples out of 702 samples, respectively. From the total of 702 samples. The concentrations of benzoic, sorbic and propionic acid were ranged from not detected (ND) to 23.74 mg/L, from ND to 7.90 mg/L, and from ND to 37.39 mg/L in cereal grains, nuts and seeds, respectively. The concentration ranges determined in this study could be used as standard criteria in the process of inspecting cereal grains, nuts and seeds for preservatives as well as to address consumer complaints or trade disputes.

본 연구에서는 곡류 및 견과 종실류 중 천연유래 보존료의 함유량을 조사하기 위하여 안식향산, 소브산 및 프로피온산의 함유량을 분석하였다. 곡류 및 견과 종실류 중 보존료 분석을 위하여 분석법을 확립하였다. 보존료 분석을 위하여 안식향산 및 소브산은 HPLC-DAD를 이용하여 정성 및 정량 분석 하였고 LC-MS/MS를 이용해 확인 분석하였다. 프로피온산은 GC-FID를 이용하여 정성 및 정량 분석 하였고 GC-MS를 이용해 확인 분석하였다. 보존료 분석법의 유효성을 검증하기 위해서 직선성, 회수율, LOD, LOQ를 검토한 결과, 모든 항목에서 양호한 결과를 나타내었다. 대상 시료는 곡류(백미, 보리, 밀 등) 275건, 견과 종실류(땅콩, 참깨, 커피원두 등) 427건을 수거하여 총 702건이었다. 함유량 조사 결과 안식향산은 대상시료 702건 중 44건의 시료에서 검출되었으며, 검출범위는 ND-23.74 mg/kg의 범위로 검출되었다. 소브산은 대상시료 702건 중 22건의 시료에서 검출되었고, 검출범위는 ND-7.90 mg/kg의 범위로 검출되었다. 프로피온산은 대상시료 702건 중 550건의 시료에서 검출되었으며, 검출범위는 ND-37.39 mg/kg의 범위로 검출되었다. 안식향산, 소브산, 프로피온산이 가장 높게 검출된 품목은 각각 참깨(23.74 mg/kg), 해바라기씨(7.90 mg/kg), 커피원두(37.39 mg/kg)이었다. 본 연구의 결과를 통해 곡류 및 견과 종실류 중 안식향산, 소브산, 프로피온산 분석법을 확립하였고 함유량조사 결과는 향후 식품 검사 시 보존료 사용기준 위반 판정으로 인한 민원제기나 국가 간 무역마찰 시 기초자료로 활용될 수 있을 것이다.
