Synbiotics

Products containing both prebiotic and probiotic ingredients are termed "synbiotics" due to the obvious potential for synergy between these ingredients. Although the prebiotic may not necessarily be utilized by the included probiotic bacteria in a synbiotic food, attempts have been made to maximize potential synergies by using complementary prebiotics that may aid the colonization and in situ functionality of the included probiotic strains. In a study in pigs, Brown et al. (160) showed that the inclusion of resistant starch or oligosaccharides in a synbiotic combination with a probiotic Bifidobacterium resulted in significantly higher numbers of bifidobacteria in the intestinal tract than with feeding of the probiotic alone. Continuing prebiotic feeding after the cessation of probiotic feeding also significantly extended the intestinal persistence of the probiotic.

In terms of potential health benefits, synbiotic combinations have shown enhanced impact over feeding solely probiotics or prebiotics in rodent models investigating anticancer effects (161-164) and colonization resistance (165). To increase the specificity of synbiotics for the added probiotic strains, bifidobacteria have themselves been exploited as a source of enzymes to synthesize NDOs (166-168) including synthesis of galacto-oligosaccharides in yoghurt during fermentation (166).
