Abstract: According to the survival rate, acid-produced capacity, configuration, growth curve and leakage rate of β-D- galactosidase (GAL), the protective effects of trehalose, lactose, sucrose, hyaluronic acid (HA), the combination of trehalose and HA and skim milk powder on Bifidobacterium longum (B.longum) were investigated. The protective effects on B. longum was conferred by all the protectants with different degrees during lyophilization and high-temperature storage, among which the combination of trehalose and HA was the most effective.
