Synergistic effects of whey protein isolate and amorphous sucrose on improving the viability and stability of powdered Lactobacillus salivarius NRRL B-30514

Amorphous sucrose, as an efficient protectant during dehydration of probiotics, can be prepared by spray drying aqueous solutions with both sucrose and whey protein isolate (WPI). The objective of this study was to characterize the synergistic effect of WPI and sucrose on protecting the survival of powdered Lactobacillus salivarius NRRL B-30514 prepared by directly mixing a cell suspension with spray-dried WPI/sucrose powders (WSP) with...
