The industrial Magnesium Chloride is one kind of Magnesium Chloride. It is specially for industrial Magnesium Chloride, commonly know as industrial Magnesium Chloride, normally contains six molecules of water of crystallization,the chemical formula of it is MgCl2 · 6H2O, easy to be deliquescent, will lose crystal water when put in dry air. It is a kind of monoclinic crystal with salty, and has certain corrosion resistance. It is widely used for the manufacture of metal magnesium, disinfectants, frozen brine, ceramics and used to fill the fabric, paper and so on. Its solution mixed with magnesium oxide, can become hard and wear resistance of magnesia cement.
“The standards of using food additives” has defined food-grade Magnesium Chloride as a stabilizer or coagulants can be used in soy products. But, at present, there are some unscrupulous traders with industrial grade Magnesium Chloride instead of food grade Magnesium Chloride, and for use in food. For example: Some of them use industrial Magnesium Chloride for instead of edible Magnesium Chloride in the production of soy products, to achieve the purpose of reducing costs. The others use industrial Magnesium Chloride for soaking Exidia auricula Judaes, after soaking, the Exidia auricula Judae flower become very big, bacterial leaves hypertrophy, sensory is very good, and the weight can increase 2~3 times.
The food grade Magnesium Chloride is on the basis of industrial Magnesium Chloride in addition to some heavy metal irons and microorganisms. Therefore, moderate consumption of food additive Magnesium Chloride will not cause and harm to the human body. Because of the industrial Magnesium Chloride are impurities and containing sulfates and various heavy metals and other harmful substances. Therefore, long term consumption can cause acute poisoning and chronic hazards, may cause uremia, gallstones, kidney stones and other diseases.
Therefore, we should be careful in the selection process of soy and Exidia auricula Judaes, while the business in the selection of Magnesium Chloride as a food additive should also attach importance to its authenticity and quality!
