A computer is adopted to calculatethe storage time value t of the chicken thigh by utilizing the chicken thigh freshness predication model; the non-conformity or conformity judgment of freshness of the chicken thigh sample is made. The detection method has the characteristics of accurate, objective and fast detection, excellent economical efficiency, and capability of supplying reliable data support to manufacturing food by using the chicken thigh with the qualified freshness. |
