Abstract

Compositions and methods for providing infant nutrition with partially hydrolysed proteins and non-digestible oligosaccharides for use in induction of oral tolerance against native dietary proteins.

First claim

What is claimed is:

1. A method for inducing oral immune tolerance against dietary protein, said method comprising administering to a subject identified as having, or at risk of having, dietary protein allergy an enteral composition comprising at least one non-digestible oligosaccharide selected from the group consisting of fructo-oligosaccharide, non-digestible dextrin, galacto-oligosaccharide, xylo-oligosaccharide, arabino-oligosaccharide, arabinogalacto-oligosaccharide, gluco-oligosaccharide, glucomanno-oligosaccharide, galactomanno-oligosaccharide, mannan-oligosaccharide, chito-oligosaccharide, uronic acid oligosaccharide, sialyloligosaccharide and fuco-oligosaccharide and at least one partial protein hydrolysate, the partial protein hydrolysate comprising at least 3 wt. % of peptides with a size of 5 kDa or above and at least 50 wt. % of peptides with a size below 5 kDa and wherein the partial protein hydrolysate is partial mammalian milk protein hydrolysate, partial whey protein hydrolysate or partial beta-lactoglobulin hydrolysate, wherein the hydrolysate has not been subjected to fermentation, such that oral immune tolerance against dietary proteins is induced in said subject.

2. The method according to claim 1 , wherein the composition comprises at least one beta-lactoglobulin peptide comprising a sequence selected from the group consisting of SEQ ID NO 1, SEQ ID NO 2, SEQ ID NO 3 and SEQ ID NO 4, and wherein the at least one beta-lactoglobulin peptide has a molecular weight below 5 kDa.

3. The method according to claim 1 , wherein the size distribution of the peptides in the partial protein hydrolysate is 60 to 90%<1 kDa, 5 to 20% 1 to <2 kDa, 2 to 16% 2 to <5 kDa, 0.6 to 3% 5 to <10 kDa, 0.5 to 2% 10 to 20 kDa and 1 to 3% >20 kDa, based on dry weight of peptides present in partial protein hydrolysate.

4. The method according to claim 1 , wherein the partial protein hydrolysate comprises a ratio of the relative amount (wt %) of peptides with a size from 2 to <5 kDa to the relative amount (wt %) of peptides with a size of at least 5 kDa is (5 to 1):1.

5. The method according to claim 1 , wherein the non-digestible oligosaccharide is selected from the group consisting of fructo-oligosaccharide, galacto-oligosaccharide and uronic acid oligosaccharide.

6. The method according to claim 1 , wherein the enteral composition comprises a protein component, a lipid component and digestible carbohydrates and wherein the protein component is present in an amount of 5 to 25% based on total calories of the composition.

7. The method according to claim 1 , wherein the enteral composition comprises 0.05 to 20 wt. % non-digestible oligosaccharide based on dry weight of the composition.

8. The method according to claim 4 wherein, in the enteral composition, the ratio of the relative amount (wt %) of peptides with a size from 2 to <5 kDa to the relative amount (wt %) of peptides with a size of at least 5 kDa is (4 to 1):1.

9. The method according to claim 1 , wherein the enteral composition is an infant formula or follow-on-formula.

10. A method for preventing inflammatory bowel disease, said method comprising administering to a subject identified as requiring prevention of inflammatory bowel disease an enteral composition comprising at least one non-digestible oligosaccharide selected from the group consisting of fructo-oligosaccharide, non-digestible dextrin, galacto-oligosaccharide, xylo-oligosaccharide, arabino-oligosaccharide, arabinogalacto-oligosaccharide, gluco-oligosaccharide, glucomanno-oligosaccharide, galactomanno-oligosaccharide, mannan-oligosaccharide, chito-oligosaccharide, uronic acid oligosaccharide, sialyloligosaccharide and fuco-oligosaccharide and at least one partial protein hydrolysate, the partial protein hydrolysate comprising at least 3 wt. % of peptides with a size of 5 kDa or above and at least 50 wt. % of peptides with a size below 5 kDa and wherein the partial protein hydrolysate is partial mammalian milk protein hydrolysate, partial whey protein hydrolysate or partial beta-lactoglobulin hydrolysate, wherein the hydrolysate has not been subjected to fermentation, such that inflammatory bowel disease is prevented in said subject.

11. The method according to claim 10 , wherein the composition comprises at least one beta-lactoglobulin peptide comprising a sequence selected from the group consisting of SEQ ID NO 1, SEQ ID NO 2, SEQ ID NO 3 and SEQ ID NO 4, and wherein the at least one beta-lactoglobulin peptide has a molecular weight below 5 kDa.

12. The method according to claim 10 , wherein the size distribution of the peptides in the partial protein hydrolysate is 60 to 90% <1 kDa, 5 to 20% 1 to <2 kDa, 2 to 16% 2 to <5 kDa, 0.6 to 3% 5 to <10 kDa, 0.5 to 2% 10 to 20 kDa and 1 to 3% >20 kDa, based on dry weight of peptides present in partial protein hydrolysate.

13. The method according to claim 10 , wherein the partial protein hydrolysate comprises a ratio of the relative amount (wt %) of peptides with a size from 2 to <5 kDa to the relative amount (wt %) of peptides with a size of at least 5 kDa is (5 to 1):1.

14. The method according to claim 10 , wherein the non-digestible oligosaccharide is selected from the group consisting of fructo-oligosaccharide, galacto-oligosaccharide and uronic acid oligosaccharide.

15. The method according to claim 10 , wherein the enteral composition comprises a protein component, a lipid component and digestible carbohydrates and wherein the protein component is present in an amount of 5 to 25% based on total calories of the composition.

16. The method according to claim 10 , wherein the enteral composition comprises 0.05 to 20 wt. % non-digestible oligosaccharide based on dry weight of the composition.

17. The method according to claim 13 , wherein, in the enteral composition, the ratio of the relative amount (wt %) of peptides with a size from 2 to <5 kDa to the relative amount (wt %) of peptides with a size of at least 5 kDa is (4 to 1):1.

18. The method according to claim 10 , wherein the enteral composition is an infant formula or follow-on-formula.

19. A method for inducing oral immune tolerance against cow's milk protein, said method comprising administering to a subject identified as having, or at risk of having, cow's milk protein allergy an enteral composition comprising at least one non-digestible oligosaccharide selected from the group consisting of fructo-oligosaccharide, non-digestible dextrin, galacto-oligosaccharide, xylo-oligosaccharide, arabino-oligosaccharide, arabinogalacto-oligosaccharide, gluco-oligosaccharide, glucomanno-oligosaccharide, galactomanno-oligosaccharide, mannan-oligosaccharide, chito-oligosaccharide, uronic acid oligosaccharide, sialyloligosaccharide and fuco-oligosaccharide and at least one partial protein hydrolysate, the partial protein hydrolysate comprising at least 3 wt. % of peptides with a size of 5 kDa or above and at least 50 wt. % of peptides with a size below 5 kDa and wherein the partial protein hydrolysate is partial mammalian milk protein hydrolysate, partial whey protein hydrolysate or partial beta-lactoglobulin hydrolysate, wherein the hydrolysate has not been subjected to fermentation, such that oral immune tolerance against cow's milk protein is induced in said subject.
