英文摘要:

      Objective To design a rapid and non-destructive control system of putrid pork detection. Methods Through the study of visible and near-infrared spectral technology, according to the characteristics of the use in the application process and combining with actual situation needs, the overall scheme of the de-tection system was designed. Results Detection system included object, testing index, structure, function and working process of the control system. Conclusion When the distance between optical fiber probe and sample height was 10 cm, a single sample detection time control was 5 s, digital signal processing (DSP) was used as core control, it could be used for the rapid and non-destructive detection of putrid pork.
