Studies of the effects of cooking and other methods of processing report no significant alterations in the protein value of meat. However, cooking at too high a temperature for long periods of time can slightly decrease the biological value of meat proteins.
What happens to proteins when cooked?
During cooking the applied heat causes proteins to vibrate. This destroys the weak bonds holding proteins in their complex shape (though this does not happen to the stronger peptide bonds). The unraveled protein strands then stick together, forming an aggregate (or network).
