Claims
1.           A heat sterilized spoonable nutritional composition comprising:
a protein source in an amount of 12 to 20% by weight of the composition, the protein source consisting of whey protein, containing whey protein micelles, and a source of casein,
wherein the spoonable nutritional composition is a liquid or semi-liquid composi tion having a viscosity of between 400 and 4000 mPa.s at 20°C measured at a shear rate of 100 s1 .
2.           The nutritional composition according to claim 1, wherein the heat sterilized nutri tional composition contains cysteine in an amount of 1.2 to 2.4 % by weight of the protein source.
3.           The nutritional composition according to any of claims 1 or 2, wherein whey pro tein is present in an amount of 4.5 to 9 % by weight of the composition.
4.           The nutritional composition according to any of claims 1 to 3, wherein casein is present in an amount of 3.5 to 13 % by weight of the composition.
5.           The nutritional composition according to any of claims 1 to 4, having a protein concentration of up to 20 g/ 100 g of the composition.
6.           The nutritional composition according to any one of claims 1 to 5, which is a nutri tional composition, a nutritional supplement, an infant formula, a follow-up for mula, a baby food formula, an infant cereal formula or a growing-up milk, an in fant or child's food supplement, a children formula, an adult nutritional composi tion, maternal nutritional supplement, bariatric formula, elderly nutritional com position or health care formula.
7.           The nutritional composition according to any one of claims 1 to 6, for use in providing nutrition to a person in need thereof, wherein the person is preferably an elderly person, a person that is in a disease state, a person that is recovering from a disease state, a person that is malnourished, or a healthy person such as a sportsman or sportswoman or an active elderly.
8.           The use of a protein source comprising whey protein containing whey protein mi celles and a source of casein, for preparing a spoonable nutritional composition comprising 12 to 20 weight % total protein, wherein the obtained spoonable nutri tional composition is a liquid or semi-liquid composition having a viscosity of be tween 400 and 4000 mPa.s at 20°C measured at a shear rate of 100 s-1.
9.           The use according to claim 8, wherein the composition contains cysteine in an amount of 1.2 to 2.4 % by weight of the protein source,
10.         The use of whey protein micelles in combination with a source of casein for con trolling the viscosity of a liquid or semi-liquid spoonable nutritional composition comprising 12 to 20 weight % total protein, the composition preferably having a pH of 6 to 8, wherein the obtained spoonable nutritional composition is a liquid or semi-liquid composition having a viscosity of between 400 and 4000 mPa.s at 20°C measured at a shear rate of 100 s-1.
11.         The use according to claim 10, wherein the composition contains cysteine in an amount of 1.2 to 2.4 % by weight of the protein source,
12.         A process for preparing a heat sterilized spoonable nutritional composition com prising a protein source in an amount of 12 to 20% by weight based on the weight of the composition, said protein source comprising whey protein containing whey protein micelles and casein, the process comprising the steps of:
(i) Providing an aqueous solution of a protein source comprising whey protein containing whey protein micelles and
(ii) Adding a protein source containing casein;
(iii) Optionally performing a homogenization treatment step;
(iv) Performing an indirect UHT heat treatment step;
(v) Optionally performing a homogenization treatment step;
wherein following steps (i) to (v) a heat sterilized spoonable nutritional composi tion which is a liquid or semi-liquid composition is obtained having a viscosity of between 400 and 4000 mPa.s at 20°C measured at a shear rate of 100 s-1.
13.         The process according to claim 12 wherein whey protein is present in an amount of 4.5 to 9% by weight of the composition.
14.         The process according to any one of claims 12 or 13 wherein casein is present in an amount of 3.5 to 13 % by weight of the composition.
15.         The process according to any of claims 12 to 14 wherein in step (iv) the indirect heat treatment step is performed using an indirect UHT treatment using a coiled tubular heat exchanger.
16.         The process according to any of claims 12 to 15 wherein following steps (i) to (v) the heat sterilized nutritional composition is dried to form a powder, preferably by spray drying.
17.         The process according to any of claims 12 to 16, wherein following steps (i) to (v) the obtained heat sterilized nutritional composition contains cysteine in an amount of 1.2 to 2.4 % by weight of the protein source.
18.         A  nutritional     composition      obtainable     by  the   process   of  any   of  claims   12  to  17.
