Food and pharmaceutical grade magnesium carbonate granules are a mineral magnesium supplement with diverse applications, offering broad prospects and market value. Strict control over product quality and safety is essential during production, while appropriate dosage and addition methods should be selected based on specific needs and processing conditions during application.
I. Properties
Appearance: Food and pharmaceutical grade magnesium carbonate granules are generally white or almost white granular or powdery substances.
Purity: The content of magnesium carbonate (MgCO₃) is usually above 98%, with the content of other impurities (such as calcium and silica) below 1%. Simultaneously, the content of heavy metals (such as lead, mercury, chromium, and copper) should comply with national health standards to ensure product safety.
Hygroscopicity: Magnesium carbonate has good hygroscopicity, which can effectively prevent the agglomeration and caking of granular or powdered materials, maintaining their loose or free-flowing state.
Solubility: Magnesium carbonate is sparingly soluble in water, making it convenient for use in various applications requiring dissolution or dispersion.
II. Applications
Pharmaceutical Industry:
Laxatives: Pharmaceutical grade magnesium carbonate is one of the most commonly used laxatives, which can be used to treat constipation and prevent intestinal diseases.
Pharmaceutical Excipients: It can increase the stability and efficacy of drugs, improving their quality.
Food Processing Industry:
Food Additives: Food grade magnesium carbonate can be added to flour, milk powder, baked goods, etc., as an anti-caking agent, leavening agent, and acidity regulator to improve the taste and quality of food.
Dietary Supplements: It can also be used as a dietary supplement to help people replenish the minerals their bodies need and meet the requirements of a healthy diet.
III. Production Process
Raw Material Preparation: High-quality natural minerals such as magnesite are selected as raw materials and undergo fine screening and purification to ensure their purity and safety meet food grade or pharmaceutical grade standards.
Chemical Reaction Synthesis: Natural minerals are converted into magnesium carbonate through chemical reactions. This process requires strict control of reaction conditions such as temperature, pressure, and reaction time to ensure product quality and purity.
Product Purification and Testing: After the reaction is completed, the obtained magnesium carbonate product is purified and tested. The purification process usually includes steps such as filtration, washing, and drying to remove impurities and moisture. The testing process involves various analytical methods, such as chemical analysis and physical performance testing, to ensure that the product meets relevant standards.
Packaging and Storage: Qualified food and pharmaceutical grade magnesium carbonate granules need to be packaged and stored. Packaging materials need to be non-toxic, harmless, and well-sealed to prevent the product from being contaminated or damaged during transportation and storage. At the same time, the storage environment needs to be controlled, such as maintaining dry, ventilated, and light-protected conditions, to prevent the product from moisture absorption, caking, or deterioration.
