OSTI ID:4349485
From international colloquium: the identification of irradiated foodstuffs; Karlsruhe, Germany (24 Oct 1973). Carotenoids, myoglobin, and chlorophylls are three widespread pigment groups of food. The influence of gamma radiation on those pigments is summarized. The influence of radurization on the carotenoids in Belgian shrimp and salmon species is discussed. The stability of those pigments in vivo is compared to the stability of BETA -carotene and canthaxanthin in modcl systems. The radioinduced alterations in myoglobins are also dealt with. Results on the influence of the presence of oxygen and/or phosphates on the forniation of MetMb are reported. It was concluded that radiopasteurization of meat may be employed without significant changes in the meat color characteristics, in contrast to heat pasteurization. The influence of gamma radiation on chlorophylls in peas is also considered. Chlorophyll b proved to be more stable than chlorophyll a. (GE)
