The solidification of an egg after boiling is primarily due to the denaturation and coagulation of proteins. Here's a detailed explanation: 1. Egg Composition Eggs are rich in proteins, particularly ovalbumin in the egg white and yolk proteins in the yolk. In their raw state, these proteins are in a native, folded structure, which is soluble in water. 2. Heat and Protein Denaturation Denaturation is the process where proteins lose their natural structure due to external stress, such as heat. When an egg is heated: The heat disrupts the hydrogen bonds, ionic bonds, and hydrophobic interactions that maintain the protein's native structure. The proteins unfold into long, loose chains. 3. Protein Coagulation After denaturation, these unfolded protein chains begin to interact with one another. Cross-linking occurs through the formation of new bonds: Disulfide bridges between sulfur-containing amino acids (like cysteine). Hydrogen bonding and hydrophobic interactions between different protein chains. This cross-linking forms a three-dimensional network, turning the liquid into a gel-like, semi-solid structure. 4. Role of Water The proteins trap water molecules within the network during coagulation. This results in the characteristic texture of boiled egg whites (firm but moist) and yolks (crumbly and dense if overcooked). 5. Temperature and Timing The degree of solidification depends on temperature and duration of cooking: Egg whites coagulate at 60–65°C (140–149°F) and become fully solid at 80°C (176°F). Egg yolks coagulate at a slightly higher temperature, starting around 65–70°C (149–158°F). 6. Irreversibility of the Process Denaturation and coagulation are irreversible processes. Once the proteins have unfolded and formed a new network, they cannot return to their native state.
