Abstract

See full text

The invention discloses a method for rapidly predicting freezer storage time of frozen pork based on reflectance ratio of two near-infrared bands. Firstly, the near-infrared spectra information of the frozen pork is obtained by a near-infrared spectrometer, and the near-infrared spectra are analyzed to obtain center values of bands centered on 1500 nm, 1350 nm and 1890 nm characteristic peaks. The ratio thereof is treated as a eigenvector, which is substituted into the characteristic exponential function based on the eigenvector and freezer storage time to calculate the freezer storage time of frozen pork. By near-infrared spectroscopy technology, the invention directly detects the freezer storage time of pork in a frozen state, significantly reduces the time required by the conventional method, and has the advantages of being fast and non-destructive.
