Survival improver and viability improving method of lactic acid bacteria, and food composition

【Task】 Such as yogurt to improve the viability of lactic acid bacteria strains, such as probiotic bacteria contained. A Survival improver of lactic acid bacteria to improve the viability of lactic acid bacteria comprising a propionic acid bacterium fermentation product. The propionic acid bacterium is a bacterium belonging to Propionibacterium (Propionibacterium) genus. The Propionibacterium (Propionibacterium) bacteria belonging to the genus is Propionibacterium & Freudenberg Reich (Propionibacterium freudenreichii). The Propionibacterium-Freudenberg Reich (Propionibacterium freudenreichii) is a Propionibacterium freudenreichii ET-3 (FERM BP-8115). .BACKGROUND
