Abstract: The combined effects of ionizing radiations (electron beams of 5.5 MeV) and non-ionizing radiations (microwaves of 2.45 GHz) on the inactivation of total number of germs (TNG) and moulds in depreciated food such as wheat bran, wheat flour and minced beef are presented. The following types of treatments were performed with electron beams (EB) and microwaves (MW): separate EB irradiation, separate MW irradiation, successive irradiation (EB irradiation followed by MW heating) named (EB+MW), successive irradiation (MW heating followed by EB irradiation) named MW+EB and simultaneous irradiation with EB and MW named S(EB+MW). The first interesting experimental result is that the microorganism's survival fraction diminishes exponentially with EB dose for the separate EB irradiation while for the separate MW irradiation the microorganism's survival fraction exhibits an oscillatory decrease versus MW dose: periods of microorganism inhibition are followed by periods of micro!
organism stimulation. The second important result is that all combined irradiation procedures such as S(EB+MW), followed by MW+EB and then by EB+MW, cause greater reduction of NTG and mould survival fractions than separate EB irradiation or separate MW irradiation. The S(EB+MW) treatment type produces the maximum reduction of NTG and moulds. The third important result is that the EB dose level could be reduced by a factor in the range of 1.5-2.5 by combined EB and MW irradiation.
