OPO refers to the addition of OPO structural lipids, which can make milk powder closer to breast milk level. The formula containing OPO structural lipids is based on cow’s milk and formulated according to the pattern and characteristics of human milk composition. The OPO structural lipids simulate the molecular structure of breast milk lipids through enzyme lipid exchange technology, which makes the nutrient types and contents of milk powder closer to breast milk, which is more suitable for the physiological characteristics and nutritional needs of infants and young children, and is beneficial for infants and young children’s absorption and reduces gastrointestinal discomforts. The formula with OPO structural lipids is suitable for infants and young children to drink, but parents should also reasonably control the amount of infants and young children each time they drink, so as to achieve scientific feeding, to avoid causing discomfort to infants and young children.
