Maltodextrin is a carbohydrate used to provide calories and is a polysaccharide nutrient that is not different in nature from flour and rice flour. The addition of maltodextrin to milk powder increases the solubility of milk powder in water, making the brewed milk more uniform, and also thickens the consistency of milk powder. The addition of maltodextrin to milk powder can provide the calories needed for baby’s growth and development with the energy produced during its decomposition and metabolism. It can also improve the digestive function of the baby’s gastrointestinal tract, as well as help the baby’s teeth to develop healthily and can reduce the occurrence of tooth decay. Maltodextrin has no obvious sweetness and does not affect the baby’s sense of taste. It is beneficial when added in moderation, but too much can affect the absorption of other nutrients.
