Abstract: Adopting alginate concentration,skim milk and milk sugar as wall material, a combining method of extrusion and freeze drying was studied to protect Lactobacillus planticola from damaging of stomach and intestines environment.This paper had found out the optimum process of making microcapsule and addtive magnitude of supporters though the orthogonal experiment .The results showed that the optimum conditions for microencapsulation were established as follows:the alginate concentration as 3%, skim milk as 4%, milk sugar as 6%, calcium chloride as 2%，and Lactics' livability reached 7.67×1010CFU/g.
