- (3) being soluble in water and forming a milk-white solution; and
- (4) said micelles are associated together in a solution having a pH in the acid range of 3 to 6 to form insoluble aggregates.
- 2. Micellar whey protein as claimed in claim 1 wherein the limited hydrolysis by a proteolytic enzyme is carried out to such an extent that the degree of proteolysis is in the range of 0.01 to 50%.
- 3. Micellar whey protein as claimed in claim 1 wherein the heat treatment is carried out at a temperature of 60.degree. to 150.degree. C.
- 4. A micellar whey protein solution comprising a micellar whey protein dissolved in water, said micellar whey protein comprising the following properties:
- (1) being obtained by heat treatment of whey protein solution, wherein the whey protein is thermally undenatured, the pH of the solution is in the range of 6 to 10, and the ash content of the solution is not greater than 0.5% by weight, having undergone limited hydrolysis by a proteolytic enzyme;
- (2) having molecules in the form of a plurality of micelles of irregular shape with a molecular weight of not less than 1,000,000 and a molecular size of 30 to 500 nm;
- (3) being soluble in water and forming a milk-white solution; and
- (4) said micelles are associated together in a solution having a pH in the acid range of 3 to 6 to form insoluble aggregates.
- 5. A purified micellar whey protein solution obtained by purifying the micellar whey protein solution of claim 4 by means of a membrane having a fractionating molecular weight of not less than 5,000 Da.
- 6. A micellar whey protein powder obtained by drying the micellar whey protein solution of claim 4.
- 7. A micellar whey protein powder obtained by drying the purified micellar whey protein solution of claim 5.
- 8. A heat-sterilized whey-protein-containing liquid drink composition based on the micellar whey protein solution of claim 4 or the purified micellar whey protein solution of claim 5.
- 9. A whey-protein-containing powdered drink composition based on the micellar whey protein powder of claim 6 or 7.
- 10. A dairy product based on a whey protein coagulum obtained by adjusting the micellar whey protein solution of claim 4, the purified micellar whey protein solution of claim 5, or a reconstituted solution of the micellar whey protein powder of claim 6 or 7 to pH 3 to 6.
- 11. A dairy product based on a coagulum of whey protein obtained by adding a neutral salt to the micellar whey protein solution of claim 4, the purified micellar whey protein solution of claim 5, or a reconstituted solution of the micellar whey protein powder of claim 6 or 7.
- 12. A heated-processed or non-heat-processed food containing the micellar whey protein solution of claim 4, the purified micellar whey protein solution of claim 5, the micellar whey protein powder of claim 6 or 7, or a reconstituted solution of the micellar whey protein powder of claim 6 or 7, as a binder, extender, water dissociation-preventing agent, emulsion stabilizer or coagulant.
- 13. A micellar whey protein product comprising the following properties:
- (1) being obtained by heat treatment of whey protein solution, wherein the whey protein is thermally undenatured, the pH of the solution is in the range of 6 to 10, and the ash content of the solution is not greater than 0.5% by weight, having undergone limited hydrolysis by a proteolytic enzyme to such an extent that the degree of proteolysis is in the range of 0.01 to 50%;
- (2) having molecules in the form of a plurality of micelles of irregular shape with a molecular weight of not less than 1,000,000 and a molecular size of 30 to 500 nm;
- (3) being soluble in water and forming a milk-white solution; and
- (4) said micelles are associated together in a solution having a pH in the acid range of 3 to 6 to form insoluble aggregates.
