One kind of royal jelly preparation of microcapsules

The present invention discloses a method for preparing microcapsules royal jelly: Preparation of 0.015 ~ 0.025g / mL of sodium alginate containing, aqueous 0.15g / mL royal jelly solution as a raw material inactive; formulation containing 5 ~ 15mg / mL of CaCl2,2.5 ~ 7.5mg / mL chitosan, 0.15g / mL royal jelly mixture, pH value of 4.5 to 6.0, supernatant after centrifugation as a coagulation bath; the positive electrode material was conveyed to the nozzle by a peristaltic pump, the head an intermediate holes disposed vertically below the top of the gel bath is stainless steel wafer as a negative electrode, a raw material liquid spray nozzle into a bath gel, calcium alginate gel beads is formed in the coagulation bath, it was filtered off with suction, washed with water, freeze-drying the jelly to obtain microcapsules. The preparation method of low temperature, short time, royal jelly lyophilized powder microcapsules reduced hygroscopicity and odorous decreased, microcapsules can withstand the gastric environment and release in the small intestine.
