Enumeration of Heat-Treated Probiotics in Functional Beverages

Key Points

• This research aims to evaluate the recovery of heat-stressed probiotics in functional beverages under specific conditions.
• Incubation of L. rhamnosus GG cells with catalase
• Assessment of culturability under anaerobic conditions
• Enumeration of colony-forming units (CFU)
• Comparison of CFU counts to AFU-equivalent levels
• L. rhamnosus GG cells recovered culturability after treatment
• Catalase facilitated true resuscitation of the cells
• CFU counts returned to levels equivalent to AFU
