Fuente: WIPO "milk" A lactose-containing food compositions for infants for improving the stool color of infants closer to that of breast-fed infants, which contains the lactose-containing foods for infants of which the only protein source is substantially cow's milk protein and/or a processed product of cow's milk protein modified to be administered to infants, and raffinose added into the foods for infants at a ratio of at least 0.05% (by weight) in a ready-to-use state. This food composition provides foods for infants more suitable for infant growth (infant formula, protein hydrolyzed formula, formula for low-birth-weight infants, follow-up formula, etc.) without causing a green stool which is observed when administering a conventional food for sucking infants, of which the only protein source is substantially cow's milk protein and/or a processed product of cow's milk protein.
