Physical, Chemical and Cooking Qualities of Eggs as Affected by Five Methods of Home Preservation

THE work described in this paper was undertaken in an attempt to obtain further information on comparative physical, chemical and cooking qualities of eggs stored by five different methods of preservation that could be easily duplicated in the home. Methods chosen for study were waterglass, freezing, application of a commercial creamy emulsion, oiling, and coating with a plastic. The eggs were tested at the end of three and six months’ storage. EXPERIMENTAL METHODS Clean, grade AA eggs from New Hampshire hens were delivered daily from the college poultry farm to the laboratory during a three-week period. All eggs except those to be frozen were dated, numbered, weighed and marked with their individual fresh weights. The eggs treated by means of commercial creamy emulsion, oiling and plastic coating were packed, small end down, in paper egg cartons. All eggs were stored in the dark at 50 to 60°F. and at a . . .
