1. a doping meat paste method for qualitative and quantitative detection based on Two-Dimensional Correlation IR Spectroscopy, it is specialLevy and be, comprise the following steps:

  • 1) prepare multiple bright flesh gruel sample and the mixed meat sample of multiple doped level meat, and gatherBright flesh gruel sample and the middle infrared spectrum of each mixed meat sample;

    2) described mid-infrared spectral dynamic spectrum is calculated;

    3) dynamic spectrum of each sample is carried out Two-dimensional Correlation Analysis, it is thus achieved that corresponding synchronization two-dimensional phaseClose spectrum and asynchronous two-dimensional correlation spectra;

    4) calculate the Euclidean distance between each bright flesh gruel sample two-dimensional correlation spectra, be designated as group inner distance;

    5) the meat paste sample of each known doped level is calculated between bright flesh gruel sample two-dimensional correlation spectraEuclidean distance, is designated as group distance;

    6) significance of difference of described group inner distance and group distance is tested, retain difference and showWrite sample data;

    7) choose testing sample, and calculate testing sample and described bright flesh gruel sample two-dimensional correlation spectraBetween Euclidean distance, be designated as unknown distance;

    8) unknown distance is carried out significance test of difference with group inner distance and all group distances, logicalSignificance of difference level between observation unknown distance and group inner distance of crossing judges to take whether testing sample adulterates,And judge to take testing sample by observing significance of difference level between unknown distance and all group distancesBelong to that doped level.
