Abstract
Abstract A hypoallergenic milk which has the flavor and smell of natural whole mammalian milk is disclosed herein. The hypoallergenic milk is preferably made from the ultrafiltrated permeate of cow's milk, which is substantially free of cow's milk protein and fat. The permeate is supplemented with, among other things, hypoallergenic protein and fat to meet the minimum daily nutritional requirements for milk.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
85 words
A hypoallergenic milk which has the flavor and smell of natural whole milk comprising: a permeate of milk, said permeate being substantially free of milk protein and fat, said permeate having been prepared by filtration of whole or skim milk through a filtration membrane without pretreating said milk to denature or hydrolyze the protein contained therein before filtration, which filtration membrane will only allow molecules with a molecular weight less than or equal to about 5 kDa to pass therethrough; hypoallergenic protein; and hypoallergenic fat.
Claim 2
Dependent Claim
85 words
A hypoallergenic milk which has the flavor and smell of natural whole milk comprising: a permeate of milk, said permeate being substantially free of milk protein and fat, said permeate having been prepared by filtration of whole or skim milk through a filtration membrane without pretreating said milk to denature or hydrolyze the protein contained therein before filtration, which filtration membrane will only allow molecules with a molecular weight less than or equal to about 5 kDa to pass therethrough; hypoallergenic protein; and hypoallergenic fat.
Claim 3
Dependent Claim
24 words
The hypoallergenic milk according to claim 1 formed from a permeate of cow's milk, said permeate being free of cow's milk protein and fat.
Claim 4
Dependent Claim
23 words
The hypoallergenic milk according to claim 2 wherein said permeate is free of molecules having a molecular weight greater than about 5 kDa.
Claim 5
Dependent Claim
23 words
The hypoallergenic milk according to claim 3 wherein said permeate is free of molecules having a molecular weight greater than about 3.5 kDa.
Claim 6
Dependent Claim
23 words
The hypoallergenic milk according to claim 4 wherein said permeate is free of molecules having a molecular weight greater than about 2 kDa.
Claim 7
Dependent Claim
23 words
The hypoallergenic milk according to claim 5 wherein said permeate is free of molecules having a molecular weight greater than about 1 kDa.
Claim 8
Dependent Claim
28 words
The hypoallergenic milk according to claim 2 wherein said permeate contains materials selected from the group consisting of riboflavin, lactose, salt or ash containing calcium and combinations thereof.
Claim 9
Dependent Claim
27 words
The hypoallergenic milk according to claim 2 wherein said hypoallergenic protein is selected from the group consisting of cereal protein sources, vegetable protein sources and combinations thereof.
Claim 10
Dependent Claim
29 words
The hypoallergenic milk according to claim 8 wherein said hypoallergenic protein comprises cereal protein selected from the group consisting of oat cereal, rice cereal, barley cereal and combinations thereof.
Claim 11
Dependent Claim
25 words
The hypoallergenic milk according to claim 2 wherein said hypoallergenic protein comprises vegetable protein sources selected from the group consisting of potato and soy isolate.
Claim 12
Dependent Claim
25 words
The hypoallergenic milk according to claim 2 wherein said hypoallergenic fat is selected from the group consisting of deproteinized butter, vegetable oil and combinations thereof.
Claim 13
Dependent Claim
29 words
The hypoallergenic milk according to claim 11 wherein said hypoallergenic fat comprises vegetable oil selected from the group consisting of milk-free margarine, sesame oil, safflower oil and combinations thereof.
Claim 14
Dependent Claim
12 words
The hypoallergenic milk according to claim 2 further comprising vitamins and minerals.
Claim 15
Dependent Claim
76 words
A process of making hypoallergenic milk comprising the steps of: providing whole or skim milk; filtering the milk through a filtration membrane without pretreating the milk to denature or hydrolyze the protein contained therein, which membrane will only allow molecules with a molecular weight less than or equal to about 5 kDa to pass therethrough; collecting the permeate from the filtering step; supplementing the permeate with hypoallergenic protein and hypoallergenic fat; and homogenizing the supplemented permeate.
Claim 16
Dependent Claim
76 words
A process of making hypoallergenic milk comprising the steps of: providing whole or skim milk; filtering the milk through a filtration membrane without pretreating the milk to denature or hydrolyze the protein contained therein, which membrane will only allow molecules with a molecular weight less than or equal to about 5 kDa to pass therethrough; collecting the permeate from the filtering step; supplementing the permeate with hypoallergenic protein and hypoallergenic fat; and homogenizing the supplemented permeate.
Claim 17
Dependent Claim
30 words
A process according to claim 14 wherein the filtration membrane will only allow molecules with a molecular weight of less than or equal to about 3.5 kDa to pass therethrough.
Claim 18
Dependent Claim
30 words
A process according to claim 15 wherein the filtration membrane will only allow molecules with a molecular weight of less than or equal to about 2 kDa to pass therethrough.
Claim 19
Dependent Claim
30 words
A process according to claim 16 wherein the filtration membrane will only allow molecules with a molecular weight of less than or equal to about 1 kDa to pass therethrough.
Claim 20
Dependent Claim
27 words
The process according to claim 14 further comprising the step of: heating the whole milk to a temperature within the range of 40° F. to 150° F.
Claim 21
Dependent Claim
23 words
The process according to claim 18 further comprising: controlling the pH of the whole milk to within the range of 2 to 11.
Claim 22
Dependent Claim
17 words
The process according to claim 14 further comprising the step of: blending the supplemented permeate before homogenizing.
Claim 23
Dependent Claim
15 words
The process according to claim 20 further comprising the step of: sterilizing the homogenized permeate.
Claim 24
Dependent Claim
15 words
The process according to claim 21 further comprising the step of: packaging the homogenized product
Claim 25
Dependent Claim
25 words
The process according to claim 14 further comprising the step of: homogenizing the supplemented permeate at a pressure between about 2000 and about 4000 P.S.I.
Claim 26
Dependent Claim
22 words
The process according to claim 14 further comprising the step of: providing a pressure gradient across the membrane of about 5 P.S.I.
Claim 27
Dependent Claim
12 words
The process according to claim 14 wherein the filtering is by dialysis.
