Abstract
The photoacoustic (PA) spectroscopy in UV and visible was demonstrated a suitable tool for measuring the effect of gamma radiation (0 to 20 kGy) on egg powders (egg yolk, egg white and whole egg). The spectra o btained indicate that the effect of gamma rays in egg white powder is weaker than that observed from whole egg and egg yolk powders. Irradia ted egg powders exhibit two peaks: one centered near 275 nm is associa ted with the content of aromatic amino acids in the sample, while anot her peak (at 480 nm) is related to the presence of carotenoids.
