摘要:

研究了热释光(TL)法用于辐照食品检测的可行性。先分离出食品中的硅酸盐类矿物质,然后在加热条件下测量硅酸盐类矿物质中由辐照而蓄积的并以光子形式释放的能量,从而判断食品是否经过辐照。实验以黑胡椒、辣椒面、桂皮、干香菇、茶叶、脱水小葱等为例进行了研究,研究结果说明,辐照食品的硅酸盐矿物质分离方法和热释光(TL)检测方法具有较高的可靠性。

Abstract:

This study investigated the feasibility of thermoluminescence (TL) method in the detection of irradiated food. Firstly, the silicate minerals were isolated from irradiated foods, then the energy in the silicate minerals, which is accumulated due to irradiation and released in the form of photon under heating condition, was detected to judge whether the foods were irradiated or not. Ten samples of black pepper, dehydrated capsicum, Chinese cinnamon bark, dehydrated mushroom, tea, dehydrated shallot, etc were analyzed. The results showed that the combination of silicate mineral isolation with TL method has a high reliability in the detection of irradiated foods.

Key words: irradiated food, thermoluminescence (TL) analysis, detection
