Granular product of dried microorganism cells and manufacturing method therefor

摘要

A grandular product is prepared by fluidizing core material such as saccharide in a granulating chamber, spraying melted binding material such as fat to the fluidized core material and concurrently feeding dried viable microorganism cells such as bifidobacterium towards the fluidized core material to form a granular product having stratified structure by adhering microorganism cells on the periphery of the core material. Since the product is prevented from permeation of atmospheric oxygen and environmental moisture, the cell survival rate of the product is higher than that of the conventional product during prolonged storage periods.
