Abstract

For the packaged fresh meat non-destructive testing, the spectrum characters and spectrum interfering of four kinds of typical packaging films were analyzed. Furthermore, the interfering mechanism of film on the spectrum detection was discussed and verified. The packaging film interference mechanism and cancellation method were proposed and verified by experiments. The results show that the loss of luminous flux of packaging film affects non-destructive testing in the packaged fresh meat. Packaging film spectral correction method eliminates the interference of packaging film on spectral detection. The modified visible spectrum of packaged fresh beef is highly consistent with the visible spectrum of the unpackaged fresh beef. The average relative error between the predicted value and the measured value is less than or equal to 4.41% and the maximum relative error is less than or equal to 5.11%. The interference of packaging film on non-destructive testing of packaged fresh meat is eliminated and the visible spectrum non-destructive testing of packaged fresh meat is also realized. The presented non-destructive detection method provides a promising quality supervising technology of packaged fresh meat during producing and selling.
