Usually, it is prepared by the reaction of lactic acid with soluble magnesium salts (such as magnesium sulfate, magnesium chloride, etc.). The finished product is obtained through steps such as dissolution, reaction, precipitation, filtration, washing, and drying.
Uses
Food Field卫健委网站: As a magnesium - rich nutrient fortifier, it can be added to beverages, dairy products, sports nutrition, baby food, etc. to supplement magnesium deficiency and enhance vitality.
Medical Field: It can be used as a medical magnesium supplement to treat magnesium - deficiency diseases. It can also be used as an osmotic laxative. After oral administration, it forms a hypertonic environment in the intestine to promote defecation.
Other Fields: In industry, it can be used as a catalyst to participate in some organic synthesis reactions; in the chemical industry, it can be used as an intermediate for the synthesis of new materials.
Usage Method
It can be directly added to the raw materials and mixed evenly, or it can be dissolved in the aqueous solution of the raw materials first and then added. The daily intake varies for different groups of people. The recommended daily intake for people under 17 years old is 30 - 50 mg, for adults is 50 - 75 mg, for pregnant women is 50 - 90 mg, and for lactating women is 75 - 110 mg. Generally, the addition amount is controlled at 0.05% - 0.2% of the total raw material weight.
Storage and Packaging
It should be stored sealed at room temperature, away from toxic, harmful, odorous substances or strong acids and alkalis. The shelf life is generally 10 months.
The packaging usually adopts a 25 - kg plastic woven bag with a non - toxic polyethylene bag inside.
