Important Facts About Eggs


Parts of an egg
Parts of an Egg Cooking Methods in Food Preparation

  • Shell: needs to be free of cracks or bacteria can get into the egg

  • Albumen: white part of the egg. Rich in protein.

  • Yolk: yellow part of the egg. Contains fat, cholesterol, vitamins A and D.

  • Chalazae: thick strands that hold the albumen in place in the egg. Looks like an umbilical cord.

Nutritional value
Nutritional Value Cooking Methods in Food Preparation

  • They are a nutrient-dense food because

    they contain about 75 calories, but are

    loaded with nutrients such as:

    • Protein

    • Fat and cholesterol

    • Folate

    • Vitamin D and A

  • Do you think that the color of the egg has anything to do with its nutritional value?

Characteristics of fresh high quality eggs
Characteristics of Fresh/High Quality Eggs Cooking Methods in Food Preparation

  • Yolk is high & firm above the white

  • Small yolk diameter

  • Yolk is centered in white

  • High ratio of thick to thin

    white

  • High standing thick white

Purchasing eggs
Purchasing Eggs Cooking Methods in Food Preparation

  • Grading

  • The best-quality eggs are graded USDA

  • Grade AA, followed by USDA Grade A.

    – The grades sold at

    supermarkets.

  • USDA Grade B, the

    lowest grade.

    – Available to food service

    establishments and not sold

    directly to consumers.


Egg sizes

The size of egg that most recipes are based upon is Large.


Egg safety tips
Egg Safety Tips Cooking Methods in Food Preparation

1. Inspect before buying and discard any

broken eggs

2. Refrigerate immediately at or below 40 F

3. Keep in cartons

4. Cook until the whites are coagulated & yolks

begin to thicken to kill the salmonella bacteria

5. Egg dishes should not be kept out >1 hour


Functions of eggs in cooking
Functions of Eggs in Cooking Cooking Methods in Food Preparation

  • Binding: eggs bind (hold together) ingredients in a recipe. Ex. Meatloaf

  • Emulsifying: eggs hold together two ingredients that normally would not stay mixed, like oil and vinegar. Ex. Mayonnaise

  • Providing structure: eggs expand with heat and provide structure to baked goods. Ex. Cooked custard.

Preparation of Eggs


How to beat egg whites into a foam
How to Beat Egg Whites into a Foam Cooking Methods in Food Preparation

  • To successfully beat egg whites to a foam one

    has to follow certain guidelines:

    a. Separate egg whites from egg yolk correctly: no trace of egg yolk can be present in the egg whites, or they will not foam due to the presence of fat in egg yolks.

    b. Only use bowls and utensils made of non-porous material such as metal or glass.

    c. Allow egg whites to stand at room temperature for 30 minutes.

    d. Use cream of tartar to stabilize the egg whites and help them come to a richer foam.


Soft peaks or stiff peaks
Soft Peaks or Stiff Peaks? Cooking Methods in Food Preparation

  • If the recipe calls for egg whites beaten to soft peaks, whip them until the mixture bend over like waves when you lift the mixer’s beaters up

  • If the recipe calls for stiff peaks, whip the eggs until the mixture stands up straight when the beaters are lifted from the mixture.

  • CAUTION: when you add the egg whites foam to the rest of the ingredients, use the “fold” technique or all the air that you incorporated in the foam will go away and your recipe will

    come out flat.


Volume stability factors of egg whites

• Temperature: Cooking Methods in Food Preparation

– room temperature

• Fat:

– decreases foam

formation

• Sugar:

– increases stability

– delays foam formation

– added at foamy or soft

peak stage

• Acid:

– increases stability

– doesn’t delay foam

formation

Cooking Eggs Cooking Methods in Food Preparation

  • Hard Cooked: boil eggs in water. As soon as the water boils remove the pan from the heat source and let stand in the hot water for 12-15 minutes. Pour the hot water out and replace with cold water. Peel and refrigerate immediately. To avoid the egg yolk turning green, do not overcook them.

  • REMEMBER: fresh eggs are harder to peel than older eggs.

  • Poaching: healthy way to cook an egg. Break the egg in simmering water and cook until done. http://www.traileraddict.com/clip/julie-julia/poaching-eggs

  • Frying: break eggs in a greased skillet and fry until the whites are set and the yolk is thick.

  • Scrambled: beat eggs before pouring them into a hot and greased skillet. Cook and stir until they thicken.

  • Baked: called shirred eggs. Break eggs and pour them into a ramekin or shallow baking pan. Bake at 325˚F. for about 15 or until thick.

  • Microwaving: never microwaving eggs in the shell and do not overcook. Pour eggs in a microwave-safe bowl and microwave, stirring often.
