A kind of preparation method of magnesium l-threonate

Abstract

The invention provides an industrial preparation method of magnesium L-threonate. According to the method, vitamin C is taken as a raw material, dissolved in a water solution and reacted with magnesium peroxide as an oxidizing agent, then peroxidase is added to a reaction system, residual oxidizing agent is removed, an ethanol water solution is used for crystallization, and magnesium L-threonate is prepared through normal-temperature crystal separation. The preparation method is screened out through process optimization, can be applied to industrial production, adopts a simple process and mild conditions, and is easy to operate and master, high in yield, environment-friendly and lower in cost.

Description

technical field

[0001] The invention relates to a preparation method of magnesium L-threonate, which belongs to the field of chemical industry. Background technique

[0002] Magnesium L-threonate is a food additive, which belongs to four-carbon polyhydroxy compounds, and is an efficient and safe magnesium nutritional supplement. Magnesium threonate is easier to metabolize and absorb in the human body than inorganic magnesium. Since L-threonate is a metabolite of L-ascorbic acid, it is safer when applied to the human body. Magnesium L-threonate can participate in the mediation of neuron activity, maintain the normal operation of cardiovascular, neuromuscular and nervous systems, and effectively improve magnesium deficiency and a series of related symptoms. Due to its high-efficiency biological activity and high safety, its research is more active and its application is more extensive.

[0003] The synthesis of L-magnesium threonate has been reported in Chinese patent 991238...
