This document summarizes a study on how the internal composition of eggs changes as they age and how this affects their culinary functionality. Eggs have both biological and culinary functions. As eggs age, their bacterial contamination is inhibited but their internal composition changes. The study tested the quality of egg yolks, albumen, and whole eggs in mayonnaise, angel cake, and sponge cake as the eggs aged to determine the effects on culinary uses. Previous research found decreasing quality in angel cakes but consistent quality in sponge cakes as eggs aged. The study aims to test methods and recommend a storage time for eggs.
