The present application relates to the technical field of
infant nutrition, in particular to a liquid
infant formula and a preparation method thereof. The liquid
infant formula provided by the present application mainly comprises
whey protein concentrate, anionic
polysaccharide, mixed
triglyceride,
osmotic pressure regulator, raw
cow milk,
lactose, complex mineral, complex
vitamin, emulsifier and water, wherein the mixed
triglyceride is compounded by medium-chain
triglyceride and long-chain triglyceride. Through the synergistic cooperation of the formula composition and the preparation process, the liquid
infant formula with both freeze-thaw resistance and high-temperature stability, which can still maintain a fluid state with uniform texture and easy
digestion under severe temperature changes, is successfully obtained, the technical problems that the existing
liquid milk is bad after being frozen and stratified after being heated are solved, and the liquid infant formula has extremely high industrial application value and economic value.
