False • Egg color is determined by the breed of the hen laying the egg, all contain the same nutritional value
A red spot found in an egg means it is an unfertilized egg, true or false
Also called “meat spots” red spots are occasionally found on an egg yolk. They are caused by a rupture of a blood vessel on the yolks surface during the formation of the egg. • Red spots are harmless and dissipate into the albumen (egg white)
No, Egg producers actually check egg quality by candling a process in which eggs are placed over lightThe eggs are graded based on consistency of shell, size of yolk and appearance
Eggs are only good until the freshness date is up on the side of the package, true or false?
Eggs actually last 4 to 5 weeks beyond the freshness date if kept in the refrigerator in the original carton
Organic or free range chicken eggs are more nutritious, true or false
False • Free- range eggs are those produced by hens raised outdoors or those who have daily access to the outdoors. The nutrient content is not affected whether hens are raised free-range or in floors or cages. Organic refers to those hens fed food grown without pesticides or commercial fertilizers
Grading refers to the size and position of yolk as well as thickness of albumen, they all taste the same and have same nutrients AA A B
However • If you want the best choice for appearance when cooked choose grade AA
When purchasing eggs most people buy: • A. Size large eggs • B. Size medium eggs • C. Size small eggs • D. Size jumbo eggs
Because most recipes are written for this sized egg most shoppers choose • Grade AA – Large Eggs • Medium eggs can be used in most recipes, • Small eggs are used commercially • Extra Large or Jumbo eggs are used for individual egg cookery
Double-yolked eggs are produced by very young hens or old hens. • It is rarer to find an egg with no yolk at all
False, Salmonella survives in the reproductive tract of the hen. Odds are 1 in 20,000 eggs may have this bacterium inside the shell of the egg white. • The white discourages growth and bacteria grow when mixed with egg yolk which happens when egg is very old
To prevent contamination of Salmonellae • Keep eggs cool in refrigerator 45oF • Use eggs within four weeks of freshness date • Cook to a temperature of 160o • Wash and sanitize containers that have held raw eggs • Do not use cracked eggs
Hen trivia: • A hen requires 24 to 26 hours to produce an egg. • To tell if an egg is raw or hard- cooked, spin it • Eggs age more in one day at room temperature than in a refrigerator in one week
