Magnesium Chloride is a food-grade highly soluble magnesium salt used as a coagulant (tofu/nigari), firming agent, magnesium supplement and de-icing agent in food and industrial applications.We supply bulk Magnesium Chloride sourced from leading China manufacturers, available in powder and flake forms for food and beverage manufacturers worldwide. Our Magnesium Chloride is widely used in tofu coagulant, canned vegetables, magnesium fortification source, de-icing and fire retardant.
Magnesium Chloride (MgCl₂) is sourced from seawater, brine lakes or mineral deposits. In food, it is best known as nigari — the traditional coagulant for making tofu (soy curd).
It also serves as a firming agent, magnesium fortification source, flavour enhancer and colour stabiliser. Food-grade MgCl₂ is available as anhydrous powder, hexahydrate crystals or liquid brine.
