Abstract

The present invention relates in general to a shelf-stable liquid enteral composition for providing nutrition, either as a supplement, or as a complete nutrition, with a high protein content of a non-hydrolyzed globular protein, in particular a whey protein.

First claim

The invention claimed is:

1. A sterilized or pasteurized liquid enteral nutritional composition having a pH of about 2 to 8 and comprising 10 to 20 g of non-hydrolysed globular protein per 100 ml of the composition, wherein the globular protein is selected from the group consisting of whey protein, pea protein, soy protein, and any mixture thereof.

2. The liquid enteral nutritional composition according to claim 1 , further comprising dietary fibre.

3. The liquid enteral nutritional composition according to claim 2 , wherein the dietary fiber comprises fructo-oligosaccharides and galacto-oligosaccharides with DP 2-10.

4. The liquid enteral nutritional composition according to claim 1 , comprising carrageenans, xanthans, pectins, galactomannans and other high molecular weight (DP>50) indigestible polysaccharides in an amount less than 20% of the weight of the dietary fibre fraction, or less than 1 g/100 ml.

5. The liquid enteral nutritional composition according to claim 1 , wherein the composition is an acidic yoghurt or juice with a pH of about 4.

6. The liquid enteral nutritional composition according to claim 1 , having a pH≧4 and ≦8.

7. The liquid enteral nutritional composition according to claim 6 , wherein the pH is in the range of 4 to 7.

8. The liquid enteral nutritional composition according to claim 1 , comprising 11 to 20 g non-hydrolyzed globular proteins per 100 ml of the composition.

9. The liquid enteral nutritional composition according to claim 8 , comprising 12-20 g non-hydrolyzed globular proteins per 100 ml of the composition.

10. The liquid enteral nutritional composition according to claim 1 , wherein the globular protein comprises whey protein concentrate (WPC), whey protein isolate (WPI), or a mixture thereof.

11. The liquid enteral nutritional composition according to claim 1 , obtainable by heat-treatment comprising the consecutive steps of:
a) adjusting the pH of an aqueous composition comprising non-hydrolysed globular proteins to a value of between about 2 and 8;
b) converting the composition of non-hydrolysed globular proteins obtained in step a) into an aerosol;
c) subjecting the aerosol obtained in step b) to a temperature of 100 to 190° C. during a time of about 30 to 300 milliseconds;
d) flash-cooling the heat-treated aerosol obtained in step c) to a temperature below 85° C. to obtain an aqueous solution comprising heat-treated globular proteins.

12. The liquid enteral nutritional composition according to claim 1 , having an energy density of at least 1.5 kcal/ml.

13. The liquid enteral nutritional composition according to claim 1 , wherein the non-hydrolysed globular proteins are in an amount at least 85 weight % of the total protein.

14. The liquid enteral nutritional composition according to claim 1 , further comprising a non-globular protein selected from the group of casein, caseinate, micellar casein isolate, and mixtures thereof.

15. The liquid enteral nutritional composition according to claim 1 , further comprising fat, the fat providing between 20 to 40% of the total energy content of the composition, and/or the composition further comprising carbohydrate, the carbohydrate providing between 30 to 60% of the total energy content of the composition.

16. The liquid enteral nutritional composition according to claim 1 , having a viscosity lower than 500 mPa·s, measured at 20° C. at a shear rate of 100 s −1 .

17. The liquid enteral nutritional composition according to claim 1 , the composition being packaged.

18. A method of providing nutrition to a person in need thereof, comprising administering to the person the nutritional composition according to claim 1 .

19. The method according to claim 18 , wherein the person is 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, a sportsman, or an active elderly.

20. A method for the heat-treatment of non-hydrolysed globular proteins, comprising the consecutive steps of:
a) adjusting the pH of an aqueous composition comprising non-hydrolysed globular proteins to a value of between about 2 and 8;
b) converting the composition of non-hydrolysed globular proteins obtained in step a) into an aerosol having a particles size that is less than about 30 μm;
c) subjecting the aerosol obtained in step b) to a temperature of 100 to 190° C. during a time of about 30 to 300 milliseconds;
d) flash-cooling the heat-treated aerosol obtained in step c) to a temperature below 85° C. to obtain an aqueous solution comprising heat-treated globular proteins,

wherein preferably at least 85 weight % of the non-hydrolysed globular proteins is whey protein.

21. The method according to claim 20 , wherein the pH in step a) is adjusted to a value between 4 and 8.
