What is the curd-like substance found in canned salmon?
A white or creamy coloured substance resembling coagulated egg white is sometimes found on the surface of canned salmon. This substance is commonly mistaken for congealed fat. In fact, it is a protein-like material present in the natural juices of raw salmon flesh that gets separated out and coagulates during the cooking process. The coagulation of these proteins is similar to the coagulation of albumen protein in raw egg white when boiled.
