Food products containing partially and/or totally denatured milk proteins

Abstract

The present invention relates to a dietary composition produced by a process involving extruding a milk containing product (e.g., milk, milk concentrate, milk protein concentrate, whey, whey concentrate, whey protein isolate, whey protein concentrate) through an extruder at about 50-about 450 rpm and at a temperature of about 40° to about 120° C. to produce the dietary fiber composition (which contains partially or totally denatured milk containing product). The present invention also concerns a food product containing at least one food ingredient and the dietary composition described herein; for example the dietary composition containing partially denatured proteins may be used to create a fully cooked, totally expanded or puffed ready-to-eat snack food product (or pellets or half products). In addition, the present invention relates to a method of making a food product, involving adding the dietary composition described herein to one or more food ingredients or adding one or more food ingredients to the dietary composition described herein. Furthermore, the present invention concerns a method of increasing fiber in the diet of a mammal, involving feeding to the mammal the fiber enriched food product described herein.

         4 . The dietary composition according to  claim 1 , wherein said protein containing product is selected from the group consisting of whey concentrate, whey protein isolate, whey protein concentrate and mixtures thereof.  
     
     
         5 . The dietary composition according to  claim 1 , wherein said protein containing product is whey protein concentrate.  
     
     
         6 . The dietary composition according to  claim 1 , wherein said temperature is about 90° to about 120° C., wherein said rpm is about 50-about 100 rpm, and wherein said dietary composition contains totally denatured protein containing product.  
     
     
         7 . The dietary composition according to  claim 1 , wherein said temperature is about 40° to about 90° C., wherein said rpm is about 150-about 250 rpm, and wherein said dietary composition contains partially denatured protein containing product.  
     
     
         8 . A food product comprising at least one food ingredient and the dietary composition according to  claim 1 .  
     
     
         9 . The food product according to  claim 8 , wherein said dietary composition contains totally denatured protein containing product and partially denatured protein containing product.  
     
     
         10 . The food product according to  claim 8 , wherein said dietary composition contains totally denatured protein containing product.  
     
     
         11 . The food product according to  claim 8 , wherein said dietary composition contains partially denatured protein containing product.  
     
     
         12 . The food product according to  claim 8 , wherein said food product is a puffed or expanded food product and said dietary composition contains partially denatured milk protein containing product.  
     
     
         13 . The food product according to  claim 12 , wherein said food ingredient is selected from the group consisting of corn, wheat, rice, barley, rye, potato, and mixtures thereof.  
     
     
         14 . A method of making a fiber enriched food product, comprising adding the dietary composition according to  claim 6  to one or more food ingredients or adding one or more food ingredients to the dietary composition according to  claim 6 .  
     
     
         13 . A method of increasing fiber in the diet of a mammal, comprising feeding to said mammal the food product according to  claim 10 .  
     
     
         14 . A method of replacing starch in a food product, said method comprising substituting the dietary composition according to  claim 7  for a portion of the starch.  
     
     
         15 . The method according to  claim 14 , said method comprising substituting the dietary composition according to  claim 7  for >0-about 60% of the starch.  
     
     
         16 . The method according to  claim 14 , wherein said food product is a puffed or expanded food product.  
     
     
         17 . A food product prepared by the method according to  claim 14 .
