Development of a Synbiotic Beverage Enriched with Bifidobacteria Strains and Fortified with Whey Proteins
نویسندگان
چکیده
The objective of this study was to develop a new synbiotic beverage evaluating the ability of some bifidobacteria strains to grow in this beverage which was fortified with whey proteins up to 20 g L-1, and enriched with 10 g L-1 of prebiotic inulin or resistant starch. The ability of Bifidobacterium strains to survive for 30 days at 4°C was evaluated in two synbiotic whey protein fortified beverages formulated with 2% of whey proteins and 1% of inulin or resistant starch. Microbial growth was significantly affected by the whey protein amount as well as by the kind of prebiotic fiber. Resistant starch promoted the growth of the Bifidobacterium pseudocatenulatum strain and its viability under cold storage, also conferring higher sensory scores. The development of this new functional beverage will allow to carry out in vivo trials in order to validate its pre- and probiotic effects.

Mechanistic research suggests a unique evolutionary relationship between complex milk oligosaccharides and cognate bifidobacteria enriched in breast-fed infants. Bovine milk oligosaccharides (BMO) were recently identified as structurally and functionally similar to human milk oligosaccharides. The present single-blind three-way crossover study is the first to determine the safety and tolerabili...

The faecal flora of a baby receiving a modern infant formula is substantially different from that of a breast fed baby. This difference is a little less when whey based formulas are used. The addition of bovine lactoferrin has no effect and there is some evidence that the presence of added iron in a formula moved the faecal flora further away from that of a breast fed baby. the iron content of ...
