Egg white in the context of "Victoria sponge cake"

Separating eggs is a process, generally used in cooking, in which the egg yolk is removed from the egg white. This allows one part of the egg to be used without the other part, or each part to be treated in different ways. Recipes for custard call for egg yolks, for example.

The most common reason for separating eggs is so the whites can be whipped. Also, because cholesterol is only found in the yolk, using only egg whites in a recipe will drastically reduce its cholesterol content.

Ketchup or catsup is a table condiment with a sweet and sour flavor. "Ketchup" now typically refers to tomato ketchup, although early recipes for different varieties contained mushrooms, oysters, mussels, egg whites, grapes, or walnuts, among other ingredients.

Tomato ketchup is made from tomatoes, sugar, and vinegar, with seasonings and spices. The spices and flavors vary but commonly include onions, allspice, coriander, cloves, cumin, garlic, mustard and sometimes include celery, cinnamon, or ginger. Tomato ketchup is often used as a condiment for dishes that are usually served hot, and are fried or greasy: e.g., french fries and other potato dishes, hamburgers, hot dogs, chicken tenders, hot sandwiches, meat pies, cooked eggs, and grilled or fried meat.

In art, in particular drawings in pastels, charcoal, chalk, and other dry media, a fixative is a kind of preserving agent applied over the top of the drawing to prevent crumbling, smudging, fading, and discolouring.In times gone by, natural substances such as diluted egg white were painted on, but today synthetic sprays are usually used. However some artists, such as the Aboriginal Australian artists at Warmun, Western Australia, use traditional substances, in this case gum gathered from local bloodwood trees.

Fixative is similar to varnish, but there are some key differences. Varnish is often used to protect paintings from atmospheric moisture, sunlight and dust; it helps to protect from being scratched, and makes the colours brighter. Fixatives prevents smearing.

Meringue (/məˈræŋ/ mə-RANG, French: [məʁɛ̃ɡ] ) is a type of dessert or candy, of French origin, traditionally made from whipped eggwhites and sugar, and occasionally an acidic ingredient such as lemon, vinegar, or cream of tartar. A binding agent such as salt, flour, or gelatin may also be added to the eggs. The key to the formation of a good meringue is the formation of stiff peaks by denaturing the protein ovalbumin (a protein in the egg whites) via mechanical shear.

They are light, airy, and sweet confections. Homemade meringues are often chewy and soft with a crisp exterior, while many commercial meringues are crisp throughout. A uniform crisp texture may be achieved at home by baking at a low temperature (80–90 °C or 176–194 °F) for an extended period of up to two hours.

Scrambled eggs is a culinary dish made from eggs (usually chicken eggs), where the whites and yolks have been stirred, whipped, or beaten together (typically with the addition of other ingredients), then heated so that the proteins denature and coagulate, and they form into "curds".

Lysis (/ˈlaɪsɪs/ LY-sis; from Greek λῠ́σῐς lýsis 'loosening') is the breaking down of the membrane of a cell, often by viral, enzymic, or osmotic (that is, "lytic" /ˈlɪtɪk/ LIT-ik) mechanisms that compromise its integrity. A fluid containing the contents of lysed cells is called a lysate. In molecular biology, biochemistry, and cell biology laboratories, cell cultures may be subjected to lysis in the process of purifying their components, as in protein purification, DNA extraction, RNA extraction, or in purifying organelles.

Many species of bacteria are subject to lysis by the enzyme lysozyme, found in animal saliva, egg white, and other secretions. Phage lytic enzymes (lysins) produced during bacteriophage infection are responsible for the ability of these viruses to lyse bacterial cells. Penicillin and related β-lactam antibiotics cause the death of bacteria through enzyme-mediated lysis that occurs after the drug causes the bacterium to form a defective cell wall. If the cell wall is completely lost and the penicillin was used on gram-positive bacteria, then the bacterium is referred to as a protoplast, but if penicillin was used on gram-negative bacteria, then it is called a spheroplast.

Boilies are a type of artificial fishing bait made from boiled paste that usually consists of fishmeals, milk proteins, bird foods, semolina and soya flour, which are mixed with egg white as a binding agent. The mixture is then boiled to form hard, round balls that diffuse evenly and slowly in water, and additional flavourings and aromatic attractants are usually included in the mixture to enhance the olfactory appeal to the fish. The spherical shape also allows the baits to be catapulted accurately when fishing at distant waters.

Though boilies are typically made and sold by large commercial suppliers, many anglers opt to make their own unique homemade boilies.

Icing, or frosting, is a sweet, often creamy glaze, made of sugar with a liquid, such as water or milk, that is often enriched with ingredients like butter, eggwhites, cream cheese, or flavorings. It is used to coat or decorate baked goods, such as cakes, donuts, or honey buns. When it is used between layers of cake, it is known as a filling in some foods.

Icing can be formed into shapes such as flowers and leaves using a pastry bag. Such decorations are commonplace on birthday and wedding cakes. Edible dyes can be added to icing mixtures to achieve a desired hue. Sprinkles, edible inks or other decorations are often used on top of icing.
