Why is fish soup white? It's mainly because of fat.
During the heating process, fish meat is often accompanied by the dissolution of some substances, which usually include free water in the meat, a small amount of fat, myoplasma protein, elastin and other myoplasma juice dissolved from muscle fiber cells, as well as the gelatinous matter formed by heat-soluble collagen. The reason why the soup produces milky white is that during the boiling or boiling process, the fat contained in the meat overflows, some water-soluble proteins in the muscle tissue and lecithin in the bone dissolve, the collagen in the meat skin hydrolyzes into gelatin molecules, at the same time, because of heating, the soup will continue to boil in the pot, boiling will make the fat tissue be crushed into small particles, while lecithin , gelatin molecules and some proteins with emulsifying properties play the role of emulsifier. They disperse tiny particles in water stably and evenly, and then form oil in water emulsion, which makes the soup as white as milk. Therefore, the milky white color of fish soup is mainly the optical effect caused by the fat in the soup being wrapped by emulsifier or soluble protein, emulsification and suspension in water.
