The probiotic culture was made by forming in biomass and suspension, encapsulating then was dried by spray drying method. microcapsule were in the range 7.4%-9.3%. Total yeast content in microcapsule were about 1.2-1.9 log cfu/ g. Screening result by Scanning Electron Microscope showed that in general has rounded form with unsmooth surfaces and some time had deep wrinkled at the surfaces. Microcapsule had various size, they were about 5-12 µm. Keywords: encapsulation, skim milk, arabic gu
