Magnesium carbonate
Food grade magnesium carbonate white monoclinic crystalline or amorphous powder. Non-toxic, tasteless and stable. Relative density 2.16. Food grade magnesium carbonate is slightly soluble in water, the aqueous solution is weakly alkaline, and the solubility in water is 0.02 (15 ℃). Soluble in acid and ammonium salt solution. It is easy to decompose into magnesium oxide and carbon dioxide when calcined. When it comes to dilute acid, it decomposes and releases carbon dioxide. Food grade magnesium carbonate is generally slightly soluble in water. When heated, it is easy to react with water (when hard water softens) to form magnesium hydroxide (because magnesium hydroxide is more insoluble than magnesium carbonate).

Food grade magnesium carbonate use: food grade magnesium carbonateIn food as additives, magnesium compensation agent; can also be used as flour improver, bread leavening agent.
food grade magnesium carbonate packaging:25kg plastic woven bag, 25kg kraft paper bag, or customized according to customer specific requirements.
Food Grade Magnesium Carbonate Storage: Food Grade Magnesium CarbonateStore in a dry, sealed, low temperature place, and pay attention to avoid light.
Food grade magnesium carbonate can be used in the production of flour improvers. In the formulation of flour improver, food grade magnesium carbonate is a very important raw material component, which can play a very large auxiliary role, greatly improve the fluidity and dispersion of flour improver, and act as an anti-caking loose agent. In general, the content of food grade magnesium carbonate in the range of 10%-15% can be, must ensure that it has good fluidity. The content of magnesium oxide in food grade magnesium carbonate is between 40% and 43%, the apparent specific volume is between 1.4 and 2.5 ml/g, and the water content is less than 1%. In addition, food grade magnesium carbonate in cosmetics, medicine, food and other industries also have a great role.
Food grade magnesium carbonate can also act as an alkaline agent, desiccant, color fixative, carrier, anti-caking agent, free flow agent, nutritional supplement, pH regulator, processing aid, release agent. As one of the components of defoaming agent, magnesium carbonate can be used in wheat flour and protein solid drinks. At the same time, magnesium carbonate also has the role of food additives in sports drinks.
