Research Progress on Freeze-drying Protectants for Probiotics
Probiotics have been widely applied in food,health products,and other industries.Freeze-drying is a common method for preparing probiotic products,but the lyophilization process often causes damage to the strains.By optimizing freeze-drying parameters and adding exogenous protectants,the survival rate of the strains during freeze-drying can be improved.However,protectants exhibit strain-specific differences.Therefore,the choice of appropriate protectants has been a hot topic in research.This article reviews probiotics,freeze-drying technology,protectants,and their research strategies,and aims to provide protective strategies for the freeze-drying of strains,thereby maximizing the freeze-drying protective effect of strains.
