FIELD: chemistry.SUBSTANCE: oligosaccharide ingredient, which is intended to increase content of sialic acid in baby formula, contains glycosylated amino acids and peptides of general formula RSac, where R is an amino acid residue, Sac is a monosaccharide selected from a group comprising N-acetyl-neuraminic acid, N-acetyl galactosamine and galactose n has a value from 1 to 10, under the condition that if n=1, then R is a threonine residue or a serine residue and if n has a value between (2) and (10) the peptide contains at least one threonine or serine residue, m has a value from 2 to 4 and at least 20 mol % of the ingredient is N-acetyl-neuraminic acid, where the oligosaccharide component contains 10-25 mol % N-acetyl galactosamine, 10-25 mol % galactose, 20-50 mol % N-acetyl-neuraminic acid and 15-50 mol % threonine or serine or mixture thereof.EFFECT: obtaining an oligosaccharide ingredient intended for increasing content of sialic acid in baby formula.6 cl, 2 ex |
