Embodiment 1
[0192] Table 1 below gives an example of the composition of an infant formula comprising an oligosaccharide mixture according to the invention. The oligosaccharide mixture may, for example, comprise 0.1 to 4.0% by weight of N-acetylated oligosaccharides, 92.0 to 99.5% by weight of galacto-oligosaccharides and 0.2 to 4.0% by weight of sialylated oligosaccharides.

Embodiment 2
[0197] research description
[0198] Five-week-old female BALB / cByJ CRL mice from Charles River were divided into groups and fed during 6 weeks based on the following schedule:
[0199] - Week 1: all groups: low fiber diet (see Table 2 for composition)
[0200] - Week 2 to Week 6:
[0201] Control group (group A): low fiber diet (same as week 1)
[0202] · Test groups (groups B to D): low fiber diet supplemented with 5% by weight of test fiber (replacing 5% of the total low fiber diet with 5% of test fiber) (same as week 1)

[0206] The following fibers were tested:
[0207] Test BMO = milk oligosaccharides: oligosaccharide mixture comprising 99.3% GOS, 0.2% N-acetylated oligosaccharides and 0.5% sialylated oligosaccharides
[0208] PDX = polydextrose

[0225] research description
[0226] Cell Lines and Culture Conditions
[0227] Human NCI-H716 cells were obtained from the American Type Culture Collection. These cells are human endocrine cells capable of secreting GLP-1.
[0228] For the maintenance of proliferation, these cells were supplemented with 10% FBS (fetal bovine serum), 2mm l-glutamine, 100IU / mL penicillin and 100μg / mL streptomycin Grow in suspension in RPMI 1640. Initiation was initiated by growing cells on Matrigel (high glucose DMEM (Dulbecco's Modified Eagle's Medium), 10% FBS, 2 mm l-glutamine, 100 IU / mL penicillin and 100 μg / mL streptomycin) coated dishes. Cell attachment and endocrine differentiation.
[0229] Secretion studies
[0230] Two days before the experiment, 1×10 6 NCI-H716 cells were seeded in Matrigel-coated 12-well culture plates. On the day of the experiment, replace the supernatant with KRB buffer (Krebs-Ringer bicarbonate buffer) with or without test reagents:
[0231] KRB b...
