Preparation of Gastrodia elata BL.extraction microcapsules

To explore new Gastrpdia elata BL.functional food, the preparation was studied and some properties of Gastrpdia elata BL.extraction-calcium alginate microcapsules were investigated.Microcapsules were constructed in CaCl 2 solution with different concentration.Gelling speed was reflected by the change of microcapsules' mass.The diameter was measured by micrometer under microscope.The release property and encapsulating rate were detected too.The result indicated that gelling was soon in the initial 8h and ideal gelling could be gotten with CaCl 2 solution above 0.1mol/L.The diameter was (214±2.1) ～ (235.9±3.3) μm.The encapsulate rate was 47.73% ±0.56% ～49.83% ±0.86% and release added up to 85% within 8h in pH6.8 phosphate buffer.Gastrpdia elata BL.extraction-alginate micro-capsules possess the potential to be used to develop new Gastrpdia elata BL.functional food.
