Uses

Magnesium chloride is used to make metal magnesium, disinfectant, fire extinguishing agent, frozen brine, ceramics, and used to fill fabrics, paper, etc.; curing agent; nutrition enhancer; taste agent (with magnesium sulfate, table salt, calcium hydrogen phosphate, calcium sulfate, etc. (Combined use); Japanese rice wine and other auxiliary agents; water removing agent (used in fish cake, dosage 0.05% to 0.1%); tissue improver (combined with polyphosphates, used as an elasticity enhancer for surimi products). Due to the strong bitterness, the commonly used amount is less than 0.1%.
