Gamma irradiation combined with mild preservative was applied to extend the shelf life of chiffon cake stored at ambient temperature. Reduction of specific volume, hardness, springiness, chewiness and crumb yellowness was noticed after irradiation at 2e10 kGy, whereas crust yellowness and peroxide values increased. Panelists could detect a decline in chiffon cake qualities, especially odor and texture.
Although overall acceptability scores significantly decreased (p < 0.05) at doses above 4 kGy, the scores did not differ significantly (p 0.05) between 2 kGy and 4 kGy
