Abstract

The present invention is in the field of protein compositions, in particular protein compositions for infant milk formula. The protein compositions according to the invention comprise whey protein, casein and high isoelectric point proteins, such as those having an isoelectric point of at least 6.0. The present invention further relates to the uses of the protein compositions.

First claim

The invention claimed is:

1. A composition comprising casein, whey protein and at least one high isoelectric protein from a non-dairy source, said high isoelectric protein having an isoelectric point of between 6.0 and 11, wherein the weight ratio of the sum of casein and whey protein to the high-isoelectric protein in the composition is between 95:5 and 75:25, wherein the composition is an infant formula comprising 0.8-3.0 g/100 ml protein when in liquid form.

2. The composition according to claim 1 , wherein the casein and whey protein are present in a weight ratio between 30:70 and 70:30.

3. The composition according to claim 1 , wherein the casein comprises β-caseins in an amount of between 35 and 60 wt. % of total casein content; and/or wherein the casein comprises α-caseins in an amount of between 20 and 60 wt. % of total casein content; and/or wherein the casein comprises k-caseins in an amount of between 15 and 30 wt. % of total casein content.

4. The composition according to claim 1 , wherein the whey protein comprises α-lactalbumin in an amount of between 20 and 80 wt. % of total whey protein content; and/or wherein the whey protein comprises β-lactoglobulin in an amount of between 20 and 70 wt. % of total whey protein content.

5. The composition according to claim 1 , wherein the high isoelectric protein is one or more proteins selected from the group consisting of lysozyme, ovotransferrin, canola protein, rapeseed protein, or mixtures thereof.

6. The composition to according to claim 1 , wherein the at least one high isoelectric protein is in intact form.

7. The composition according to claim 1 , wherein only one high isoelectric protein having an isoelectric point between 9.0 and 11 is present.

8. The composition according to claim 1 , wherein the composition comprises two high isoelectric proteins from a non-dairy source having an isoelectric point between 6.0 and 11, wherein one of the isoelectric proteins has an isoelectric point between 9.0 and 11.

9. The composition according to claim 1 , consisting of casein, whey protein and at least one high isoelectric protein, including one high isoelectric protein from a non-dairy source.

10. A composition comprising casein, whey protein and at least one high isoelectric protein from a non-dairy source, said high isoelectric protein having an isoelectric point of between 6.0 and 11, wherein the weight ratio of the sum of casein and whey protein to the high-isoelectric protein in the composition is between 95:5 and 75:25, wherein the composition is an infant formula, wherein the infant formula comprises lipid, protein and digestible carbohydrates, with 5 to 20 energy % protein, based on total calories provided by the composition, and wherein the infant formula comprises 50 to 90 kcal/100 ml when in liquid form.

11. The composition according to claim 10 , wherein the infant formula comprises 60 to 70 kcal/100 ml when in liquid form.

12. A composition comprising casein, whey protein and at least one high isoelectric protein from a non-dairy source, said high isoelectric protein having an isoelectric point of between 6.0 and 11, wherein the weight ratio of the sum of casein and whey protein to the high-isoelectric protein in the composition is between 95:5 and 75:25, wherein the composition is an infant formula in liquid form, comprising 0.8-3.0 g/100 ml protein.

13. A composition comprising casein, whey protein and at least one high isoelectric protein from a non-dairy source, said high isoelectric protein having an isoelectric point of between 6.0 and 11, wherein the weight ratio of the sum of casein and whey protein to the high-isoelectric protein in the composition is between 95:5 and 75:25, wherein the composition is an infant formula in liquid form, wherein the infant formula comprises lipid, protein and digestible carbohydrates, with 5 to 20 energy % protein, based on total calories provided by the composition, and wherein the infant formula comprises 50 to 90 kcal/100 ml when in liquid form.

14. The composition according to claim 13 , wherein the infant formula comprises 60 to 70 kcal/100 ml liquid.
