    A Factors influencing shape of sodium alginate microcapsules

  • Original language description

    Methods for obtaining microcapsules based on polymers of animal and vegetable origin are rapidly developing branch of biotechnology. One of these methods is electrospray or formation of microcapsules under influence of an electrostatic potential. The mainadvantage of this method is the possibility of obtaining microspheres of uniform size in a wide range from 50 µm to 1 mm. Shape of the obtained microcarriers can be affected by such parameters of electrospray as applied voltage, the distance between the contacts, and the polymer dosing rate. The purpose was to study the influence of electrospray-operating parameters on shape of alginate microcapsules. An analysis of the differential distribution curves by equivalent circle diameter of microcapsules depending on voltage has shown that up to 5000+-158 V there is one pronounced peak in the region of 90+-4.9 µm. Voltage above 5000+-158 V during the production of microcapsules by electrospray leads to significant changes in distribution of microcapsules by equivalent circle. Diameter and Wadell sphericity coefficient. Increasing the dosing rate of the sodium alginate leads to a significant increase in equivalent circle diameter, but does not affect the distribution of microcapsules by ellipticity coefficient and Wadell sphericity coefficient.
