This paper presents an economical system for measuring the bioimpedance of meat. The measurement is based on the electrical Fricke model and the inverting configuration of operational amplifiers (op-amp). The system can generate testing signals with frequency ranged from 10Hz to 1MHz and adjustable amplitude up to 1.08Vpp. The sweeping input and output of the op-amp are captured by an oscilloscope that is connected to and controlled by a computer before being processed by MATLAB. The system allows performing automatic customizable sweep routines. Generally, the measurement on a resistor and a RC meat-modeling circuit and a meat sample provided favorable results. In the future, system will be used for measurement and assessment meat quality in order to create a new methods for assessment of food quality.
