Abstract
The present invention relates to whey protein aggregate particles that can be used to stabilize foams, and more particularly edible foams, such as foamed dairy products. The invention provides a process for preparation of such whey protein aggregates, for the use of such particles for stabilizing foam, as well as edible foams or foamed product comprising such whey protein aggregate particles.
Claims14
A process for the preparation of whey protein aggregate particles comprising the steps:
- a. dispersing whey protein in an aqueous medium to form an aqueous solution;
- b. adjusting the pH of the solution obtained in step a) to a pH above 7;
- c. allowing the whey protein to hydrate in the solution obtained in step b);
- d. denaturing and gelling the whey protein by heating the solution of hydrated whey protein obtained in step c);
- e. drying the denatured and gelled whey protein obtained in step d) to form dry whey protein aggregate;
- and
- f. reducing the dried whey protein aggregate to a particle powder.
A method for creating an edible foam or for promoting the creation of an edible foam comprising using whey protein aggregate particles to produce the foam, the particles being produced by the steps:
- a. dispersing whey protein in an aqueous medium to form an aqueous solution;
- b. adjusting the pH of the solution obtained in step a) to a pH above 7;
- c. allowing the whey protein to hydrate in the solution obtained in step b);
- d. denaturing and gelling the whey protein by heating the solution of hydrated whey protein obtained in step c);
- e. drying the denatured and gelled whey protein obtained in step d) to form dry whey protein aggregate;
- and
- f. reducing the dried whey protein aggregate to a particle powder.
Method for stabilizing an edible foam comprising using whey protein aggregate particles to produce the foam, the particles being produced by the steps:
- a. dispersing whey protein in an aqueous medium to form an aqueous solution;
- b. adjusting the pH of the solution obtained in step a) to a pH above 7;
- c. allowing the whey protein to hydrate in the solution obtained in step b);
- d. denaturing and gelling the whey protein by heating the solution of hydrated whey protein obtained in step c);
- e. drying the denatured and gelled whey protein obtained in step d) to form dry whey protein aggregate;
- and
- f. reducing the dried whey protein aggregate to a particle powder.
A method for stabilizing a foam, comprising adding whey protein aggregate particles produced by the steps:
- a. dispersing whey protein in an aqueous medium to form an aqueous solution;
- b. adjusting the pH of the solution obtained in step a) to a pH above 7;
- c. allowing the whey protein to hydrate in the solution obtained in step b);
- d. denaturing and gelling the whey protein by heating the solution of hydrated whey protein obtained in step c);
- e. drying the denatured and gelled whey protein obtained in step d) to form dry whey protein aggregate;
- and
- f. reducing the dried whey protein aggregate to a particle powder to an edible composition intended to be foamed prior to formation of the foam.
11-13. (canceled)
A method for producing a foamed edible product comprising
- adding whey protein aggregate particles produced by the steps:
- a. dispersing whey protein in an aqueous medium to form an aqueous solution;
- b. adjusting the pH of the solution obtained in step a) to a pH above 7;
- c. allowing the whey protein to hydrate in the solution obtained in step b);
- d. denaturing and gelling the whey protein by heating the solution of hydrated whey protein obtained in step c);
- e. drying the denatured and gelled whey protein obtained in step d) to form dry whey protein aggregate;
- and
- f. reducing the dried whey protein aggregate to a particle powder to an edible composition prior to formation of the foam;
- and
- inducing foam formation in the edible composition obtained, so as to form a foamed edible product.
