摘　　要：基于近红外检测技术,设计了近红外猪肉新鲜度检测仪。该仪器以近红外发光二极管为光源,硅光电二极管作为检测器,由近红外发射、信号变换及电源电路等3个模块组成。相比近红外光谱仪,该仪器具有结构简单、体积小、成本低和使用方便等特点。用该仪器对不同存放时间的猪肉样品进行检测实验,结果表明:输出信号有较好的区分度,可对猪肉的新鲜度进行无损检测。Detection instrument of pork freshness is designed based on near infrared technique,with LED as light source and Silicon Photodiode as detector.This instrument is composed of three parts： near infrared emission;signal transformation;and power circuit.Compared with near infrared spectrometer,this instrument has many advantages,such as simple structure,convenient use,small in size and low in cost.Results of detecting pork sample with different storing time showed clear difference in output signal.Thus,nondestructive detection can be used to detect pork freshness with this instrument.
