This invention provides a synbiotic for regulating
protein allergy, an infant
amino acid formula
powder, and its preparation method, belonging to the field of milk
powder technology. A synbiotic for regulating
protein allergy comprises the following components in parts by weight: 10-30 parts of galactooligosaccharides, 1-3 parts of fructooligosaccharides, 5-15 parts of 2'-fucosylated
lactose, 1-3 parts of
lactose-N-neotetrasaccharide, 1-2 parts of
sodium 3'-sialotyl-
lactose, and 0.1-5 parts of
Bifidobacterium longum subsp. infantis M-63. The synbiotic components work synergistically to deeply mimic the mechanisms of action of
breast milk in building intestinal
microecology, regulating immune function, and promoting digestive comfort. Combined with amino acids, nucleotides, and other nutrients, this formula is formulated into an infant
amino acid formula
powder, which can effectively reduce
allergy symptoms and reactions, providing a scientific nutritional solution that closely approximates the physiological benefits of
breast milk for allergic infants who cannot be breastfed.
