摘要：
A method and system for evaluating food safety of a food product (P). An electric signal (Se) is used for generating an oscillating electric field (E) in a radio wave frequency range permeating at least part of the food product (P) and measuring a response of the permeated part of the food product (P) to the electric field (E) to determine a test value (e2) indicative of a permittivity (µ) of the food product (P) at one or more frequencies (É) in the radio wave frequency range. The test value (e2) is compared with a reference value (e1) indicative of the permittivity (µ) at the at the same one or more frequencies (É) of a reference food product (P') in a known coagulation state (U). An evaluation parameter can be generated for rejecting (R) or accepting (A) the food product (P) based on the comparison.
