Human milk fortifier

A process of manufacturing a human milk fortifier composition that comprises:

• a protein component in an amount ranging from 6 wt/wt % to 35 wt/wt % on a solids basis;
• a fat component in an amount ranging from 0.1 wt/wt % to 36 wt/wt % on solids basis;
• and
• a carbohydrate selected from the group of Lactose and Oligosaccharides present in the milk fortifier composition in an amount from 25 wt/wt % to 75 wt/wt % on solids basis,
• the method comprising:
• a. pooling human donor milk;
• b. separating fat from the pooled human donor milk to produce a skim milk;
• c. optionally microfiltrating the skimmed milk
• d. pasteurizing the skimmed milk;
• e. ultrafiltrating the skim milk resulting into a retentate consisting of concentrate protein and a permeate;
• diafiltrating the milk to further concentrate protein;
• f. concentrating the permeate using vacuum evaporation followed by cooling of the permeate to crystalize the lactose;
• g. washing of lactose crystals from permeate resulting into recovering of the essential nutrients with low molecular weight;
• h. following the step f and g above repeatedly on the filtrate thus recovered from permeate to remove lactose;
• i. mixing back the filtrate with the retentate recovering essential nutrients in retentate and creating a blend;
• and
• j. optionally adding cream, lactose and other minerals and nutrients to the blend to achieve a specific desired final composition.
