Dielectric properties of supersaturated alpha-D-glucose aqueous solutions at 2450 MHz.

Dielectric properties of supersaturated alpha-D-glucose aqueous solutions (45-56% w/w) at 2.45 GHz were investigated at temperatures ranging from 25 degrees C to 85 degrees C. Penetration depth was calculated as well. At each temperature tested, there exists a concentration range at which the dielectric constants or loss factors for supersaturated glucose solutions are independent of concentration. These results will be helpful in studies of the Maillard reaction as it occurs in a microwave field.
