Abstract: Electrical impedance refers to the ability of media to impede current in circuit. When the texture structure of muscle has been changed, the capability to impede current will also change. The quality of meat can be fast and accurately controlled on the basis of the relationship between electronic impendence parameters and meat quality parameters. In this paper, the basic principle of electrical impedance technology is introduced. The applications of electronic impedance technology in detecting pH change in bovine, pork carcass rigor mortis and aging process, controlling the aging process and evaluating intramuscular fat are also discussed. Meanwhile, the future development trend of electronic impedance technology is proposed, which will provide a reference for the quality control of meat by electronic impedance technology.

Key words: electrical impedance technology, rapid detection, aging control, meat quality
