The invention relates to a mixture of human milk oligosaccharides that consists essentially of: a)a component A which is 3-FL or DFL, a component B which is LNT, LNnT, LNFP-I or 2'-FL, a component C, which is -LNFP-II when component B is LNT, or -LNFP-III when component B is LNnT, or -LNDFH-I when component B is LNFP-I, or -DFL when component B is 2'-FL, and a component D, which is -lactose when component A is 3-FL, or -2'-FL when component A is DFL, with the proviso that if component B is 2'-FL,then component A is 3-FL； or consists essentially of: b)3-FL, a component Ewhich is LNT, LNnT or LNFP-I, and a component F, which is -LNFP-II when component E is LNT, or -LNFP-III when component Eis LNnT, or -LNDFH-I when component E is LNFP-I, and to processes for producing them and their uses.
