A modified microencapsulation method based on emulsion technique was investigated in this study to produce microcapsules with diameters below 100μM. Recent study has indicated that it is possible to control the alginate microspheres size by using high stirring speed 400 rpm for 20 min of emulsion and produce spherical beads in the range of 10-30μM.It was shown that the microencapsulation process yield of alginate beads may be dependent on the surfactant type and concentraion as well as the volume of calcium chloride solution.Tween 80 had better ability than lecithin in alginate bead production and higher volume of CaCl2 solution resulted high microencapsulation process yield.The improved method allowed us to produce micron size beads rather than millimetre sizes which were reported by previous researchers.It gives a smooth texture when the beads are incorporated into products.Future studies are needed to monitor the effect of other surfactants on the microencapsulation process yield as well as studying the effect of various surfactants on the viability of probiotic bacteria.
