Magnesium chloride (E511 is an important coagulant used in the preparation of cheese and tofu. In Japan it is sold as nigari (derived from the Japanese word for "bitter"), In China, it is called lushui. Nigari or lushui consists mostly of magnesium chloride, with some magnesium sulfate and other trace elements. It is also an ingredient in baby formula milk.
