Abstract
Egg albumen was modified to improve water retention properties of the coagulated, frozen and thawed product. Albumen was found to contribute more to expressible moisture (%EM) of coagulated whole egg mixture than yolk. For frozen and nonfrozen treatments, albumen (pH gt; 9.5) reduced %EM in both the coagulated albumen and whole egg mixtures made with pH‐adjusted albumen. Succinylated albumen (≤0.2% g anhydridelg albumen) reduced %EM for frozen and nonfrozen treatments. Albumen at pH 10.5 and 11.0 required less time to attain an equivalent cook value than at pH 7.0,8.0,9.0, and 10.0.
