Abstract

The present invention pertains to a new type of denatured whey protein compositions having a low content of soluble whey protein and a high content of protein and to a method of producing them. In particular, the present invention pertains to the new type of denatured whey protein compositions having a low content of soluble whey protein, a high content of protein and low content of fat and to a method of producing them. The invention furthermore pertains to products containing the high protein denatured whey protein compositions, particularly high protein, acidified dairy products, and additional uses thereof.

4. The acidified dairy product according to claim 1 , wherein the acidified dairy product is a yoghurt.

5. A method of producing an acidified dairy product, the method comprising the steps of:
a) providing a dairy base comprising at least one dairy component and at least one carbohydrate,
b) pasteurising the dairy base at a temperature in the range of 70-150 degrees C. and subsequently cooling the dairy base,
c) contacting the heat-treated dairy base with an acidifying agent,
d) allowing the acidifying agent to reduce the pH of the dairy base to a pH of at most 5,
e) optionally, subjecting the acidified dairy base to one or more additional processing steps,
f) optionally, packaging the final acidified dairy product in a suitable container,
wherein:
I) the dairy base provided in step a) comprises a total amount of protein of at least 7% (w/w), the solids of a denatured whey protein composition in an amount of at least 2% (w/w), a total amount of CMP of at least 2% (w/w) relative to the total amount of protein, and a total amount of fat of at most 0.3% (w/w), wherein the denatured whey protein composition contains:
a total amount of protein of at least 70% (w/w) on a dry weight basis,
a total amount of fat of at most 2% (w/w) on a dry weight basis,
insoluble whey protein particles having a particle size in the range of 1-10 microns, where the amount of said insoluble whey protein particles is in the range of 50-100% (w/w) relative to the total amount of protein, and
a total amount of CMP of at least 10% (w/w) relative to the total amount of protein; or

II) an ingredient comprising the solids of denatured whey protein composition is added to the dairy base between steps a) and I) in an amount sufficient to form the acidified dairy product containing:
a total amount of protein of at least 7% (w/w),
the solids of the denatured whey protein composition in an amount of at least 2% (w/w), and
a total amount of CMP of at least 2% (w/w) relative to the total amount of protein, and

a total amount of fat of at most 0.3% (w/w), wherein the denatured whey protein composition contains:
a total amount of protein of at least 70% (w/w) on a dry weight basis,
a total amount of fat of at most 2% (w/w) on a dry weight basis,
insoluble whey protein particles having a particle size in the range of 1-10 microns, where the amount of said insoluble whey protein particles is in the range of 50-100% (w/w) relative to the total amount of protein, and
a total amount of CMP of at least 10% (w/w) relative to the total amount of protein.

6. A denatured whey protein composition containing:
