Effect of galacto-oligosaccharides: Maltodextrin matrices on the recovery of Lactobacillus plantarum after spray-drying
In this work maltodextrins were added to commercial galacto-oligosaccharides (GOS) in a 1:1 ratio and their thermophysical characteristics were analyzed. GOS:MD solutions were then used as matrices during spray-drying of Lactobacillus plantarum CIDCA 83114. The obtained powders were equilibrated at...
