Gamma irradiation at a dose of 4 kGy effectively prolonged
microbiological spoilage from 3 d to 90 d at ambient temperature
and successfully achieved decontamination of A.flavus. The shelf life
of irradiated chiffon cake was, however, shortened to 75 d when
rancidity was concerned. Thus, gamma irradiation could be
employed instead of using chemical preservatives. Shelf-stable
chiffon cake was successfully developed without necessarily
modifying product qualities (aw and pH) and storage conditions.
