Magnesium Chloride FCC Food Grade
MgCl2·6H2O Formula weight 203.30

Magnesium Chloride occurs as colorless flakes or crystals. It contains six molecules of water of hydration. It is hygroscopic, very soluble in water, and freely soluble in alcohol.

Identification: A 1:10 aqueous solution gives positive tests for Magnesium and for Chloride.
Assay: Not less than 99.0% and not more than 105.0% of MgCl2·6H2O.
Ammonium: Not more than 0.005%.
Lead: Not more than 4 mg/kg.
Sulfate: Not more than 0.03%.

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.

A jackal woke up early in the morning and went in to the plains. He looked at his long shadow in the rising morning sun and said to himself, "I must have a camel for my meal today".

He kept moving around till noon and it was getting hot and the jackal was tired. He was also hungry and thirsty. He looked at his small shadow in the mid-day sun. He murmered, "I was only joking about the camel, a mouse will do".
