Abstract

The invention relates to a method of separating components from milk, and the apparatus used therefor. The invention also relates to compositions prepared from the separated components. The present invention relates to nutritional milk compositions and products which are designed to include per serving size a specified percentage range of one or more components separated from milk. The compositions of the present invention can optionally include non-essential but nutritionally functional components. The complete nutritional milk compositions of the present invention can be provided as unflavored milks, flavored milks, ice creams and yogurts.

Claims

exact text as granted — not AI-modified
1 . A method for separating milk components comprising, 
 ultrafiltrating the milk to produce a first liquid permeate and a first retentate;    nanofiltrating the first liquid permeate to produce a second liquid permeate and a second retentate; and,    reverse osmosis of the second liquid permeate to produce a third liquid permeate and a third retentate.    
   
   
       2 . The method of  claim 1  further comprising an optional separation step, wherein said separation step precedes the ultrafiltration step.  
   
   
       3 . The method of  claim 2  further comprising a microfiltration step, wherein said microfiltration step follows the optional separation step and precedes the ultrafiltration step.  
   
   
       4 . The method of  claim 2  further comprising a diafiltration step, wherein said diafiltration step follows the ultrafiltration step and precedes the nanofiltration step.  
   
   
       5 . The method of  claim 1 , wherein the protein content of the first retentate is at least 9 wt % and the lactose content is at least 4 wt %.  
   
   
       6 . The method of  claim 1 , wherein the lactose content of the second retentate is at least 13 wt %.  
   
   
       7 . The method of  claim 1 , wherein the lactose content of the third liquid permeate is no more than 0.05 wt % and the mineral content is no more than 0.05 wt %.  
   
   
       8 . A dairy composition comprising 2 wt % butter fat, 4.5 wt % protein, 0.8 wt % minerals and 2 wt % lactose, wherein said composition is prepared by combining 5.01 v % butter fat, 32.1 v % UF retentate, 15.7 v % RO retentate and 47.19 v % water.  
   
   
       9 . A dairy composition comprising 0.26 wt % butter fat, 8.6 wt % protein, 1.6 wt % minerals and 3 wt % lactose, wherein said composition is prepared by combining 63.6 v % UF retentate and 36.4 v % RO retentate.  
   
   
       10 . A dairy composition prepared by combining one or more milk components selected from the group consisting of butter fat, skim milk, MF permeate, MF retentate, UF permeate, UF retentate, DF permeate, DF retentate, NF retentate, NF permeate, RO permeate and RO retentate.  
   
   
       11 . The composition of  claim 10  wherein said composition is an ice cream, a yogurt, a frozen yogurt or a frozen dessert.  
   
   
       12 . The composition of  claim 11  wherein said yogurt is selected from the group consisting of a set yogurt, a stirred yogurt, a fruit yogurt, a drinkable yogurt and combinations thereof.  
   
   
       13 . The composition of  claim 10  wherein the milk is selected from the group consisting of fat-free milk, low-fat milk, full-fat milk, lactose-free milk, concentrated milk, dry milk, organic milk and combinations thereof.  
   
   
       14 . The composition of  claim 10  wherein said composition is a flavored dairy-product.  
   
   
       15 . The composition of  claim 14  wherein the flavor is selected from the group consisting of chocolate, strawberry, vanilla, banana, raspberry, coffee, mocha and combinations thereof.  
   
   
       16 . The composition of  claim 10 , wherein milk components are derived from plant or animal sources.  
   
   
       17 . The composition of  claim 16 , wherein the animal source of milk is selected from the group consisting of human, cow, sheep, goat, buffalo, camel, llama, mare, deer and combinations thereof.  
   
   
       18 . The composition of  claim 16 , wherein the plant source of milk is soy bean.  
   
   
       19 . The composition of  claim 10 , wherein said milk is fortified with proteins.  
   
   
       20 . The composition of  claim 10  wherein said milk is fortified with dietary fiber.
