Embodiment 1
[0036] Infant formula milk powder of the present invention and preparation method comprise the steps:
[0037] First prepare the milk mineral salts:
[0038] (1) Using non-fermented fresh milk as raw material, macromolecular substances such as fat and casein are removed by microfiltration, and the whey liquid obtained by separation is intercepted by ultrafiltration to remove whey protein, and a permeable milk containing lactose and minerals is obtained. For liquid filtration, the molecular weight cut-off of the ultrafiltration membrane is 10000, the filtration pressure is 0.3-0.8MPa, and the filtration temperature is 10-15°C;
[0039] (2) The lactose and mineral solution are then subjected to nanofiltration to obtain a mineral solution. The molecular weight cut-off of the nanofiltration membrane is 350, the filtration pressure is 1.5-3.0 MPa, and the filtration temperature is 10-15°C;
[0040] (3) The mineral solution is pasteurized at a temperature of 95°C for 5 seconds; the...
