production method | the methods for producing Magnesium gluconate include chemical synthesis, electrochemical method, photochemical method and biological enzyme method, as a food additive is limited to enzymatic production of products. 10% glucose solution, Disinfection for 20min under 0.1MPa, as the fermentation medium, adding 10% of Aspergillus niger seed liquid, fermentation culture at 31 ℃ on Shaker, magnesium carbonate was added during fermentation; the fermentation broth is filtered and decolorized by activated carbon, transferred to a rotary distiller, distilled under reduced pressure at 60 ° C., concentrated to 55g/109; Then cooled to crystallize, suction filtered, washed, and dried at ° C. To obtain a finished product. |
