Molecular gastronomy is the scientific approach of cuisine from primarily the perspective of chemistry. The composition (molecular structure), properties (mass, viscosity, etc) and transformations (chemical reactions, reactant products) of an ingredient are addressed and utilized in the preparation and appreciation of the ingested products.
Egg white. A raw egg with the round orange yolk (containing the visible white chalaza) in the center surrounded by the transparent yellow egg white. Egg white is the clear liquid (also called the albumen or the glair / glaire) contained within an egg. In chickens, it is formed from the layers of secretions of the anterior section of the hen's ...
In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiation, or heat.

Starch gelatinization. Starch gelatinization is a process of breaking down of intermolecular bonds of starch molecules in the presence of water and heat, allowing the hydrogen bonding sites (the hydroxyl hydrogen and oxygen) to engage more water. This irreversibly dissolves the starch granule in water. Water acts as a plasticizer.
The friction from beating the eggs adds heat to the process, which causes the proteins to increase in elasticity. As the proteins are being stretched during the denaturation process they are also coagulating together forming a protein network. After the denaturation process the egg whites will become six to eight times their original size.
Curing: Cure eggs in a mixture of salt and sugar, which preserves them. Storing in oil: Submerge hard-boiled eggs in oil, such as olive oil, in a sealed jar. This can prevent oxidation and ...
Equilibrium unfolding. In biochemistry, equilibrium unfolding is the process of unfolding a protein or RNA molecule by gradually changing its environment, such as by changing the temperature or pressure, pH, adding chemical denaturants, or applying force as with an atomic force microscope tip. [1][2] If the equilibrium was maintained at all ...
To tell if a hard-boiled egg is bad, peel the egg and check for discoloration or unpleasant odor, suggests Clark. “A fresh hard-boiled egg should have a yellow yolk and a firm white,” she says ...
