Abstract
The migration of liquid paraffin (crystol 70, Esso), which was applied to chicken shell eggs, to the shell interior was measured with the help of 3H-labelled liquid paraffin tracer. When the dip-oiling eggs were stored for 1-6 days, most (97.4%) of the radioactivity remained in shell and shell membrane, and 2.6% of the activity were found in albumen and yolk. Less (1.4%) radioactivity was present in albumen and yolk of spray-oiling eggs.
The concentrations of paraffin in the edible part (albumen and yolk) of the dip-oiling eggs and the spray-oiling eggs were 28 and 17ppm, respectively.
