INTESTINAL IMMUNE SYSTEM ENHANCER CONTAINING CELL WALL COMPONENT OF LACTIC ACID BACTERIA

摘要

PROBLEM TO BE SOLVED: To provide an intestinal immune system enhancer which contains a component derived from lactic acid bacteria having a high intestinal immune enhancing effect as an active ingredient.SOLUTION: The intestinal immune system enhancer contains the cell wall component of lactic acid bacteria which has an IgA antibody production improving action as an active ingredient. The cell wall component is the cell wall of lactic acid bacteria, or a soluble component or an insoluble residue obtained by solvent extraction of the cell wall of the lactic acid bacteria, and the lactic acid bacteria are preferably lactic acid bacteria belonging to Lactobacillus plantarum, particularly preferably a Lactobacillus plantarum AYA (Accession number FERM P-21106).
