The Application of High Pressure Electrostatic in Microcapsule Preparation

Abstract:

High pressure electrostatic (HPE) was applied to prepare microcapsules, and the operation parameters of HPE were investigated in this paper. When ecletrocity voltage is 20 kV and the distance between two electrodes is 5 cm, the diameter of micro-beads can be around 500 μm that is the optimal diameter for dispersing in water. The release rate of BSA was coming up to 45% after 120 min in AGF and even to 89% after 240 min in AIF at 37°C to basically meet the release in full. The amount of bacteria in 2% (w/v) Na-alginate microparticles declined to 4.08 log cfu per ml which is 4 times more than that of free bifidobacteria after 120 min in AGF with incubation time by 5 log cycles.
