The subject of the present invention is to provide a magnesium oxide suitable for use in medicine or for food addition, specifically, a magnesium oxide particle that can reduce the compression problem and the abnormal quality characteristics of the tablet during compression, and a magnesium oxide particle that can reduce the compression problem and the abnormal quality characteristics of the tablet with low mixing of heavy metals and high purity of magnesium oxide.
The present invention provides a magnesium oxide particle for pharmaceutical use or food addition, in which the BET specific surface area is 7 to 50m2/g and CAA80/CAA40 is 2 to 7.
In the production process often see the tablet rupture not forming, sticky punch, sticking, missing, falling powder and other abnormal phenomena, Hebei magnesium biological limited company according to the production characteristics of the product to adjust the production method, combined with market demand, the production of magnesium oxide particles made of tablets, the strength of sufficient not easy to crack, clean and no gray edge, black edge, both can effectively reduce the tablet manufacturing process of pressure, and can improve its production efficiency.
Food grade granular magnesium oxide is used as food additive, color stabilizer, pH regulator as health care products, food magnesium supplement. Used as decolorizer for sugar refining ice cream powder pH regulator etc. As anti-caking agent and anti-acid agent used in wheat flour, milk powder chocolate, cocoa powder, grape powder, sugar powder and other fields, also can be used in the manufacture of ceramics, enamel, glass, dyestuff and other fields.
Pharmaceutical grade granular magnesium oxide can be used as antacid, adsorbent, desulfurizer, de-lead agent, complexing filtering aid, PH regulator in medicine as antacid and light laxative, inhibit and relieve excessive stomach acid, treat gastric ulcer and duodenal ulcer disease. It has strong, slow and long-lasting effect in neutralizing stomach acid and does not produce carbon dioxide.
