How would you describe a high quality egg?
How could you rapidly age an egg so that the air cell would increase in size?
Refrigeration keeps the air cell small so you could rapidly age the egg by exposing it to higher temperatures.
1 day at room temperature equals 7 days in the refrigerator
Which egg is higher quality? Why?
The one labeled A is higher quality because the albumen (egg white is more compact) and the height of the yolk and albumen is higher indicating there has been less breakdown of the vitelline (yolk) membrane and albumen.
Can you get avian influenza from eating an egg?
No. The temperatures during pasteurization and cooking eggs and egg products is more than adequate to inactive any virus.
