Differences Between Food Grade Magnesium Chloride and Industrial Grade Magnesium Chloride

I. Main Functions of Food Grade Magnesium Chloride

As its name implies, food grade magnesium chloride is safe for human consumption.It is commonly used in the production of pig blood curd, duck blood curd, brined tofu, soybean jelly and other protein-rich products.Food grade magnesium chloride acts as a flocculant and coagulant, thus improving the texture and taste of food.

II. What is Industrial Grade Magnesium Chloride?

1. In the chemical industry, industrial magnesium chloride is an important inorganic raw material. It is used to produce magnesium products such as magnesium carbonate and magnesium oxide, and also serves as a raw material for antifreeze.

2. In the metallurgical industry, it is used to produce metallic magnesium (obtained by molten electrolysis), liquid chlorine, high-purity magnesia, etc.

3. In the building materials industry, industrial magnesium chloride is a key raw material for manufacturing lightweight building materials for high-rise buildings, such as fiberglass tiles, decorative panels, sanitary ware, ceilings, floor tiles, magnesium oxychloride cement, ventilation ducts, anti-theft manhole covers, fire doors and windows, fireproof boards, partition boards and artificial marble.In magnesite products, it can be used to produce high-quality magnesium tiles, high-grade fireproof boards, magnesium packaging boxes, magnesium decoration panels, lightweight wall panels, abrasive tools, stoves, fireworks binders, etc.

4. In other fields, industrial magnesium chloride can be used as a food additive, protein coagulant, snow-melting agent, refrigerant, dust suppressant, refractory material, etc.Tofu coagulated with brine (aqueous magnesium chloride solution) is more tender and delicious than tofu coagulated with gypsum.

5. In the metallurgical industry: It is used to manufacture refractory materials and binders for furnace linings, and is also a raw material for producing No. 2 flux and smelting metallic magnesium.

6. In the machinery industry: Magnesia cement can be made into mechanical packaging boxes, triangular edge protectors, furniture, etc., which is a good material for “replacing synthetic materials with mineral materials”.

III. Differences Between Industrial Grade and Food Grade Magnesium Chloride

The differences are mainly in the following aspects:

1. Different production processesFood grade magnesium chloride is produced by further refining industrial grade magnesium chloride.

2. Different product quality standardsThe limits of several core indicators are significantly different:

· Sulfate content: Food grade ≤ 0.4%; Industrial grade ≤ 1%–2.8%

· Lead content: Food grade ≤ 1 mg/kg; Industrial grade: no requirement

· Arsenic content: Food grade ≤ 0.5 mg/kg; Industrial grade: no requirement

· Ammonium content: Food grade ≤ 50 mg/kg; Industrial grade: no requirement

3. Different applications

Food grade magnesium chloride can be used as a food additive in the production of soybean products.

Industrial grade magnesium chloride can only be used in industrial fields, such as the production of other chemical products, floor tiles, sanitary ware, snow-melting agents, etc.

Conclusion

It is obvious that there are great differences between food grade and industrial grade magnesium chloride.Accordingly, the price of food grade magnesium chloride is much higher than that of industrial grade.Some small merchants may not understand these differences and mistakenly use industrial magnesium chloride as food grade, which may cause adverse reactions such as nausea and vomiting after consumption.
