Chemical and Organoleptic Properties of Irradiated Dried Whole Egg and Egg Yolk.

The influence of Co gamma radiation on the chemical and organoleptic properties of solid whole egg and solid egg yolk has been studied to provide a basis for assessing the feasibility of the radicidation of Salmonella in egg powder. Irradiation up to 10 kGy did not produce measurable changes in acidity, vitamins B or B. Radiolytic changes in the fatty component included the decomposition of triglycerides, the formation of hydroperoxides, and the degradation of carotenoids.
