Study Notes
About Eggs
- Eggs are an essential ingredient in many recipes and cuisines.
- They are versatile and can be consumed on their own or used in various dishes.
- Chicken eggs are the most consumed, but eggs from ducks, geese, turkeys, and wild birds are also used.
Components of an Egg
- An egg is a compact and almost complete food, providing 70 calories of energy.
- It contains essential carbohydrates, fats, proteins, minerals, salts, vitamins, and water.
- The average egg is composed of 10% shell, 30% yolk, 60% white, and 73% water.
Storing Eggs
- Eggs must be stored away from contaminating odors due to the porous shell.
- Leaving eggs in their original cardboard container helps keep them fresh.
- Eggs should be stored in a cool, dry place between 2°C and 5°C.
Testing an Egg for Freshness
- To test an egg's freshness, gently drop it into a basin of cold water.
- A very fresh egg will sink to the bottom and remain there.
- An egg that dips but floats at an angle or stands on end is slightly older (1-2 weeks old) but still safe to eat.
- An egg that floats is too old and should be discarded.
Cooking Eggs
- The basic principle of cooking eggs involves the coagulation of proteins in the yolk and white when heated.
- The coagulation temperature depends on the intensity of heat, cooking period, and presence of other ingredients like water, milk, sugar, and salt.
- Overcooking eggs can make them tough.
Cracking Eggs
- The most common technique for cracking eggs is to break them on the rim of a bowl or pan.
- Problems encountered when cracking eggs include the yolk breaking or shell fragments entering the dish.
- Cracking eggs on a flat countertop can minimize these problems.

- The average egg is composed of 10% shell, 30% yolk, and 60% white, with 73% of its constituents being water.
Storing Eggs
- Eggshells are very porous, so they must be stored away from contaminating odors.
- It's recommended to store eggs in their original cardboard container to keep them fresh.
- Eggs should be stored in a cool, dry place at a temperature between 2°C and 5°C.
Testing an Egg for Freshness
- To test an egg's freshness, gently drop it into a dish of cold water.
- If the egg sinks to the bottom, turns over, and remains there, it's very fresh.
- If it dips but floats at an angle or stands on end, it's slightly older (1-2 weeks) but still safe to eat.
- If it floats, it's too old and should be thrown away.
Cooking Eggs
- The basic principle of cooking eggs is the coagulation of proteins in the yolk and white when heated.
- The coagulation temperature depends on the intensity of heat, cooking period, and presence of other ingredients like water, milk, sugar, and salt.
- Sugar increases the temperature at which coagulation takes place, while acid and salt speed up the process.
- Overcooking eggs can make them tough.
Cracking Eggs
- The most common technique for cracking eggs is to break them on the rim of a bowl or pan.
- Cracking eggs on a flat countertop instead of a bowl rim can help prevent yolk breaks and shell fragments.
