METHODS FOR OBTAINING STERILE MILK AND COMPOSITIONS THEREOF
The disclosure provides a simple and effective methods for sterilization of milk without degradation or loss of biologically active agents in the milk and the products produced by such methods.
1 . A method for promoting growth of a premature infant, comprising administering a concentrated human milk nutritional formulation comprising 24 kcal/ounce to a premature infant,
wherein the concentrated human milk nutritional formulation comprising 24 kcal/ounce is derived from pooled human milk from multiple qualified donors; comprises human milk protein, fat, and carbohydrates; and has reduced bioburden in comparison to raw human milk.
2 . The method of claim 1 , wherein the concentrated human milk nutritional formulation comprises about 20-70 mg/mL human milk protein, about 70-115 mg/mL human milk carbohydrates, and comprises about 35-85 mg/mL human milk fat.
3 . The method of claim 1 , wherein the osmolality of the concentrated human milk nutritional formulation is less than about 400 mOsm/Kg H 2 O.
4 . The method of claim 3 , wherein the osmolality of the concentrated human milk nutritional formulation is from about 310 mOsm/Kg H 2 O to about 380 mOsm/Kg H 2 O.
5 . The method of claim 1 , wherein the improved human milk nutritional formulation does not comprise xenogeneic components.
6 . The method of claim 1 , wherein the concentrated human milk nutritional formulation comprises added minerals selected from the group consisting of calcium, phosphorus, magnesium, zinc, manganese, copper, sodium, potassium, chloride, and iron.
7 . The method of claim 1 , wherein the concentrated human milk nutritional formulation is an ultrafiltered formulation.
8 . A method for making an improved concentrated human milk nutritional formulation comprising:
(i) collecting milk from qualified human milk donors, wherein each of the qualified donors has been qualified by interview and by screening one or more biological samples from each of the donors, wherein the one or more biological samples are screened for viral and bacterial pathogens, wherein the one or more biological samples screened for viral and bacterial pathogens comprises a blood sample, wherein the donors are qualified if (a) the interview indicates the donors are not chronically ill and (b) the one or more samples are negative for viral and bacterial pathogens, wherein the milk collected from the qualified donors is screened for drugs of abuse, wherein milk that tests positive for drugs of abuse is discarded, and wherein the milk collected is matched to a qualified donor by comparing molecular markers in the collected milk with molecular markers obtained from one or more biological samples collected from the qualified donor;
(ii) pooling the milk collected from and matched to the qualified donors to create a pool of qualified milk; and
(iii) processing the pool of qualified milk in order to make the improved concentrated human milk nutritional formulation, wherein the processing comprises concentrating one or more nutrients in the pool of qualified milk and one or more steps to reduce the bioburden of the pool of qualified milk;
thereby making a concentrated human milk formulation comprising human protein, fat, and carbohydrates.
9 . The method of claim 8 , wherein the improved concentrated human milk nutritional formulation comprises about 24 kcal/ounce.
10 . The method of claim 8 , wherein the improved concentrated human milk nutritional formulation comprises about 20 kcal/ounce.
