Abstract： This paper mainly describes the efficacy and microencapsulation of Lactobacillus plantarum， the selection of microcapsule wall materials and the composite technology of wall materials， and the main embedding technology of probiotic microcapsules. The purpose is to explore the feasibility of preparing Lactobacillus plantarum microcapsules by extrusion method with modified konjac gum， sodium alginate and whey protein as the composite embedding wall materials， so as to provide a new idea for the development of microcapsule wall materials.

Keywords： konjac gum modification; Lactobacillus plantarum; microcapsule
