abstract
Two groups of eggs were stored at 15C for 0, 5 and 10 days. One group was stored, with the shell removed, in sterile WhirlPak bags. A second group was stored as intact whole eggs. Viscosity index, apparent elasticity, and initial penetration force were determined for heatinduced (80C, 80 min) gels of the thick, thin and mixed albumens from each group. The rheological parameters increased with storage time, with the greater increase exhibited by the gels of the albumens that were stored as shell eggs. Solution pH was a major factor controlling these rheological properties of heated egg albumen. Copyright 1982, Wiley Blackwell. All rights reserved
