【摘要】：为实现食品中毒素的现场快速检测,设计了一种基于移动终端的麻痹性贝类毒素现场高通量快速检测系统。采用PSP试剂盒对毒素进行显色反应,实现了一定浓度范围内的毒素检测;采用暗室结构,配合面光源透射,提供了稳定的检测环境;采用具有较高像素摄像头的移动终端对反应结果进行采集和处理,实现了检测结果的精确分析和高效交互。以实际样品作为对象进行了系统的功能测试,并与商用酶标仪的结果进行了对比,证明该系统能够较为准确地测得样品中麻痹性毒素的浓度,且检测速度较快,灵敏度较高。结果表明,本系统操作简单,且具有较高的灵敏度、检测速度和通量,能在现场实现麻痹性贝类毒素的快速检测,为食品安全评估提供了一种高效的初筛手段。
[Abstract]:In order to realize the rapid detection of toxins in food, a high throughput fast detection system for paralytic shellfish toxins based on mobile terminal was designed. The PSP kit was used to react with the toxin to detect the toxin in a certain concentration range, and a stable detection environment was provided by using the darkroom structure and the transmission of the surface light source. A mobile terminal with a high pixel camera is used to collect and process the response results, which realizes the accurate analysis and efficient interaction of the detection results. The function of the system was tested with the actual sample as the object, and compared with the result of the commercial enzyme marker. It was proved that the system could accurately measure the concentration of paralytic toxin in the sample, and the detection speed was faster and the sensitivity was higher. The results show that the system is easy to operate and has high sensitivity, detection speed and flux. It can quickly detect paralytic shellfish toxins in the field, and provides an efficient method for food safety evaluation.
