技术领域
本发明涉及食品安全检测技术领域,更具体地说是指一种便携式黄曲霉素检测设备及方法。
背景技术
现代黄曲霉毒素(Aflatoxin)是黄曲霉菌和寄生曲霉菌的一种代谢产物,普遍存在于自然界中。黄曲霉毒素应该是目前世界上最知名和最被深入研究的霉菌毒素之一。
黄曲霉毒素能造成多种疾病,如急性肝功能衰竭,肝坏死,大脑水肿,肺水肿,睾丸萎缩等,同时也是世界各卫生机构公认的高致癌物质,被WHO等国际组织定义为1类致癌物质。黄曲霉毒素进入人体和动物体以后,在肝脏中的存留量是最多的(是其他组织器官的5-15倍),对于肝脏的损害也是最大的。高剂量的黄曲霉毒素的摄入会导致急性肝损伤,如急性肝功能衰竭等。而长期低剂量的黄曲霉毒素的摄入也会对人体特别是肝脏造成不同程度的损害。
黄曲霉毒素在自然界中多来自于谷物(如玉米,大米,小麦,高粱等),坚果(花生,杏仁,葵瓜子仁等)中的霉变成分,同时也存在于用这些作物制备的饲料以及通过饲料饲育的禽畜体内。黄曲霉毒素除了通过谷物和坚果类等作物进入人体以外,也能通过奶中的代谢物进入人体。
由于黄曲霉毒素普通存在我们普通的食物中,为了食物安全需要随身携带方便检测黄曲霉毒素的设备和简易方法。
因此,有必要开发出一种便携式黄曲霉素检测设备及方法。

E.将要检测的待检测物牛奶摇匀,并均匀酒在薄纸上面浸湿表面放置在筛孔板上;
F.在365nm紫外线照射下,牛奶中的待检测物中含有黄曲霉毒素M1和M2物质时,表面发蓝紫色荧光;
G.将含有黄曲霉毒素的待检测物食品颗粒从筛孔板分离取出来,或杀毒处理,清洁干净备下次使用,并将操作过的待检物做无害化处理。
进一步方案为,所述的待采样区设置有筛孔板,对等检测样品进行筛选并抽取放置。
进一步方案为,所述的光源模块从检测设备上可拆卸移动。
进一步方案为,所述的光源模块设置有光源按键。
进一步方案为,所述的光线传感器分析检测待采样区的反射光的光谱,并通过电路分析系统输入信息给数据显示屏。
进一步方案为,所述的功能按键设有电源开关、光线传感器开关、数据显示开关和筛孔板振动开关。
进一步方案为,所述的检测设备设有充电接口,并可以便携移动。
本发明与现有技术相比的有益效果是:采用可移动便携式检测黄曲霉素设备,对待检测食品样品分析黄曲霉素成份显示,减少了传统检测设备庞大的体积和复杂的操作,并且光源模块可拆卸随便发现存在黄曲霉素的食品,再具体对食品进行成份分析筛选,降低了成本,便携式方便检测随时随地存在的食品安全问题。
