Benefits of technology

[0008] The present invention relates to a dietary composition produced by a process involving extruding a milk protein 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 composition (which contains partially or totally denatured milk protein containing product). The present invention also concerns a food product containing at least one food ingredient and the dietary composition described herein. 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.

Problems solved by technology

Fortifying snacks with whey proteins could provide a particularly attractive outlet for surplus whey proteins; however, this practice has been limited due to known adverse textural effects when the whey protein concentrate supplementation is greater than 10% of the main starch component (Kim, C. H., and J. A. Maga, Lebensmittel-Wissenchaft und-Technologie, 20: 311-318 (1987)).

Materials And Methods:

[0023] Whey protein concentrate (ALACEN 834) and lactalbumin (ALATAL 825) were purchased from New Zealand Milk Products, Inc. (Santa Rosa, Calif.). Whey Protein Isolate (PROVON 190) was purchased from Glanbia Ingredients. The compositions were as follows: WPC80 (whey protein concentrate, 80% protein), moisture 2.8%, protein 83.6%, fat 0.8, ash 3.3%, carbohydrate by difference; WLAC (whey lactalbumin), moisture 5.5%, protein 89.9%, fat 3.8, ash 0.5%, carbohydrate by difference; Whey Protein Isolate (WPI), moisture 2.8%, protein 89.6%, fat 25, ash 3.3%, carbohydrate by difference.

[0024] A ZSK-30 twin screw extruder (Krupp Werner Pfleiderer Co., Ramsey, N.J.) with a smooth barrel was used. The extruder had nine zones, and the effective cooking zones 6, 7, 8, and 9 were set to the same temperature for each test. To achieve different melt temperatures the cooking zones were set to the same barrel temperature of 35, 50, 75, or 100° C. respectively. Zones 1 to 3 we...

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.
