Abstract

In this study, the physicochemical properties of irradiated (gamma-ray and electron-beam) soybeans with different processing (dry and powder) and origins (Korea, China, and USA) were investigated and compared. The results of photostimulated luminescence (PSL) screening indicated that all non-irradiated soybeans showed photon counts (PCs) ${\leq}700$, while all irradiated soybeans showed positive values-gamma-ray 5,815-39,591 count/min; electron beam 5,791-60,055 count/min. The results of thermoluminescence (TL) analysis of all irradiated soybeans indicated that the $TL_1$ glow curves exhibited maximum peaks at 150-250. TL ratio of irradiated samples was ${\geq}0.1$; therefore, the clear identification of irradiated samples was guaranteed by analysis of the $TL_1$ curve shape and TL ratios. The results of electron spin resonance (ESR) signal of 3 irradiated and dried soybeans showed two side peaks mutually spaced at 6.0 mT (cellulose radical). Non-specific signal was detected for all irradiated soybean powders; hence, ESR analysis could not be performed.

식품의 다양한 가공특성별 조사처리 식품의 분석법 적용성을 검토하기 위하여 감마선과 전자선 조사처리 대두의 가공특성(건조, 분쇄) 및 원산지(국산, 중국산, 미국산)별 물리적 확인시험법을 이용한 판별 특성을 확인하였다. 광자극발광(PSL) 분석 결과 비조사시료는 266-395 count/min으로 $700^{\circ}C$ 이하의 값을 나타내어 음성(negative) 값으로 나타나 조사처리 되지 않은 시료로 확인되었다. 감마선과 전자선을 조사처리한 대두는 감마선의 경우 5,815-39,591 count/min, 전자선의 경우 5,791-60,055 count/min의 결과로 모두 5,000 count/min 이상인 양성(positive)값을 나타내어 대두는 가공특성, 선종, 선량에 관계없이 조사처리 판별이 가능한 것으로 나타났다. 열발광분석(TL)을 통한 조사처리 확인에서는 비조사 시료는 $300^{\circ}C$ 이상에서 자연방사선에 의한 발광곡선을 나타내었고 감마선과 전자선 조사처리 대두에서는 $150-250^{\circ}C$에서 조사처리에 의한 최대곡선을 나타내어 조사처리 판별이 가능하였다. 전자스핀공명 분석 결과는 건조대두의 껍질에서 조사 처리에 의한 cellulose radical이 확인되었으며 분쇄한 대두의 경우에는 비조사시료와 조사처리에 의한 뚜렷한 차이를 보이지 않아 조사처리 판별이 어려운 것으로 확인되었다.
