It is what inflates the dish, creating the airy architecture. The motion of beating egg whites traps air into the mix. The egg white protein seals around pockets of air, creating bubbles. Egg yolks are separated out because their fat prevents those bubbles from forming.
Why are egg whites used in soufflés?
Egg whites contain a bunch of protein, which is the substance that will allow our soufflé to both rise and to set. The process starts by using the whisk or beaters to coax the tightly coiled protein strands so they relax and expand.
What is egg white foam used for?
Egg white foam is a type of foam (a colloid in which a gas is dispersed or spread throughout a liquid) used in meringues, soufflés, and angel food cake to make them light and porous (airy). To prepare an egg white foam, egg whites are initially beaten (with a wire wisk or electric mixer) until they become frothy.
What is the function of egg in souffle?
They provide volume and structure to soufflés, angel food cake and meringues. Room temperature egg whites create the best foam volume and stability. Adding an acid (e.g. cream of tartar, vinegar, lemon juice) will help to strengthen and stabilize a foam.
Why does whisking the egg whites create a foam?
When you beat an egg white, these proteins uncurl and stretch out. … As you beat the egg whites, you also whip bubbles into the mixture. The water molecules and egg-white proteins bump around, jockeying for position. The water molecules are attracted to each other and to the hydrophilic amino acids on the proteins.
What is the secret for a souffle?
There’s only one serious secret to the perfect soufflé and that is careful whisking of the egg whites so they keep their volume and puff to a maximum in the oven. The whites should be at room temperature and you can reckon at least one and a half per person.

Don’t bake it for too long
Those souffles that collapse when a pin drops are too dry. Souffles become dry when they bake for too long. In order to make sure your souffle is cooked enough, but not too much, jiggle the dish just a bit a few minutes before it’s supposed to be done baking.
How does egg yolk affect egg white foam?
The neutral lipid fraction of egg yolk caused the major detrimental effect on foaming, and phospholipids fraction did not give significant foaming reduction at a concentration as high as 0.1%. … Therefore, yolk contamination of the egg white was the major factor in reducing foaming properties of the white protein.
What is an example of eggs as a foam?
An example of a colloid foam (gas in liquid) used in cooking is egg white which is a gas dispersed or spread throughout a liquid.
What is the role of protein in foam formation?
Intermolecular forces, conformation, and flexibility of proteins play an important role in foam stabilization. An adsorbed protein layer at air/water interfaces imparts interfacial rheology that is necessary to improve the shelf life of foam products.
Why did my souffle not rise?
If the souffle didn’t rise: Perhaps the base was too thick and thus too heavy for the whites to push up against. Another reason could be that the whites were overmixed with the base. Another cause is that the beaten whites, or the uncooked souffle, sat for too long before baking.
Why is my souffle runny?
Watch the cooking time carefully and keep a constant eye on soufflés in the oven. Besides improperly whipping the egg whites, the other most common cause of failed soufflés is under- or over-cooking.

What creates foam?
Foam is an object formed by trapping pockets of gas in a liquid or solid. A bath sponge and the head on a glass of beer are examples of foams. In most foams, the volume of gas is large, with thin films of liquid or solid separating the regions of gas. Soap foams are also known as suds.

Why do you have to be quiet when making a souffle?
The myth about them falling when there is a loud noise or a slight bump is entirely false. Soufflés will inevitably collapse, not because of being bumped, but because the air that is whipped into the egg whites, which has been heated by the oven, cools, so the soufflé falls. That’s why they are best served immediately.
Why is my souffle flat?
If assembled too early, the cheese will settle to the bottom of the baking dish and the fluffly egg white mixture to the top. In the oven, the souffle will form an especially high crown. When removed from the oven, the crown collapses, and underneath it you will find a flat, heavy, eggy layer of cheese.
What does cream of tartar do in souffle?
Cream of tartar, a byproduct of wine and grape juice processing, is an acidic salt that acts as a stabilizer in recipes that require whipped egg whites, such as meringue, angel food cake, and soufflé. … The longer the egg whites are whipped, the more tightly the albumen proteins cluster together.
What happens when you over Beat egg white?
Instead of blending into the batter, over-whipped whites form stubborn, dry clumps. When clumps persist despite your best efforts to fold, you may be tempted to do what you know you shouldn’t do: mix, stir, smear, or mash—whatever it takes to get that dry white foam incorporated into the batter.
Why are my egg whites not whipping?
New, room temperature egg whites will whip up faster than old, cold eggs. Make sure the bowl you whip the egg whites in is free from any greasy residue. Make sure that no egg yolk is in with the egg whites. Egg yolks are very high in fat and will hinder the whipping process.
What happens to the egg white as the chick grows?
As a result, an air cell forms at the large end of the egg. While the embryo is growing, the shell membranes surround and contain the white or albumen of the egg. The albumen provides the liquid medium in which the embryo develops, and it also contains a large amount of the protein necessary for proper development.
What is foaming in food?
In cuisine, foam is a gelling or stabilizing agent in which air is suspended. Foams have been present in many forms over the history of cooking, such as whipped cream, meringue and mousse. In these cases, the incorporation of air or another gas creates a lighter texture and a different mouth feel.

What other factors can affect the egg white foam stability?
The factors influencing the formation and sta- bility of egg white foam are: hen age, egg age, storage conditions, speed and time of whipping, temperature, pasteurisation, pH, dry matter, pres- ence of egg yolk or lipids, salt, sugar, stabilisers and surface active compounds, metal ions, and proteolytic enzymes (Hata …
Which of the following stabilizes an egg white foam?
The right amount of sugar stabilizes the egg foam
Besides adding sweetness, sugar helps stabilize the meringue’s structure. When sugar is beaten into an egg-white foam, it dissolves in the protein film on the surface of the air bubbles.
Is a souffle supposed to be runny in the middle?
Soufflés are best when they’re still slightly runny in the centre. To check if a soufflé is set, gently tap the dish – it should wobble just a little bit. If the centre seems too fluid, cook for a few more minutes.
Why is it called a ramekin?
The term is derived from the French ramequin, a cheese- or meat-based dish baked in a small mould.

This happens if you added too much eggs, OR you didn’t cook the dough long enough, and have too much water in your dough. Whatever you do, NEVER ADD EXTRA FLOUR!
What happens if you whip eggs?
When beaten, the protein structure of the egg white breaks down, and over time, those unfolded proteins will rearrange into a new, expanded form. Whipped egg whites can increase in size up to 8 times larger than its original volume, and this foaming ability makes it an all-star aerator in baked goods.
Is egg white foam safe?
However, many feel it isn’t as luscious and silky as the foam you get from eggs. So unless you’re vegan or nervous, stick to egg whites — you’ll be fine.
What lowers the quality of egg foam?
