Abstract: The coaxial line transmission and reflection method was applied to set up the dielectric measuring system.The permittivity and conductivity of commercial dairy products including butter.cheese.yogurt and milk had been measured at 25±0.5℃ at microwave frequencies of 2,2.45,3GHz.The results might provide the available bank of dielectric data on dairy products.

Key words: Dairy products Permittivity Conductivity Microwave
