Abstract

The present disclosure relates to methods for treating at least one source of proteins, treated protein material obtainable by said method of treatment, and food compositions for animals, preferably for pets, including said treated protein material.

First claim

1 . A method for treating at least one source of proteins comprising the steps of:
(a) heating at least one source of proteins; (b) separating the material obtained in step (a) into a solid component (i) and a liquid component (ii); (c) drying the solid component (i); and (d) physical grinding of the material obtained in step (c); characterized in that step (c) is performed on the solid component (i) without reintroducing the liquid component (ii).

2 . The method of claim 1 , wherein the source of proteins is selected from bones, carcasses, internal organs, necks or heads, or a combination thereof, and/or the animal source is chicken.

3 . (canceled)

4 . The method of claim 1 , wherein the liquid component (ii) is then treated to supply a solid fraction (iii) and a liquid fraction (iv), and in which the solid fraction (iii) is then combined with solid component (i) before step (c) or step (d).

5 . The method of claim 1 , wherein step (a) comprises heating the at least one source of proteins to a temperature at which the fat contained in the source of proteins are molten.

6 . The method of claim 1 , wherein step (b) is performed using a screw press, a Tricanter, a decanter or any other suitable equipment, preferably a screw press, and preferably a double-screw press.

7 . The method of claim 1 , wherein step (c) is performed in a dryer, at a temperature between 65° C. and 145° C.

8 . (canceled)

9 . A method for obtaining a treated protein material comprising:
(a) heating at least one source of proteins; (b) separating the material obtained in step (a) into a solid component (i) and a liquid component (ii); (c) drying the solid component (i) with at least on source of amino acids and/or at least one source of sugar; and (d) reintroducing the liquid component (ii) in the second vessel to the solid component (i); and, (e) grinding of the dried mixture obtained in step (d) thereby obtaining a treated protein material.

10 . The method of claim 9 , wherein the source of animal proteins is selected from bones, carcasses, internal organs, necks or heads, or a combination thereof.

11 - 13 . (canceled)

14 . The method of claim 9 , wherein the amino acids in step (c) are selected from lysine, cysteine, glycine, methionine or a combination thereof.

15 . The method of claim 9 , wherein the sugar in step (c) is selected from xylose, dextrose or a combination thereof.

16 . The method of claim 9 , wherein the amino acids and/or sugars are added in step (c) in an amount ranging from about 0.01% to about 1% by weight on a dry matter basis.

17 - 18 . (canceled)

19 . The method of claim 9 , wherein step (d) is performed at a pH from about 6 to about 8.

20 . The method of claim 9 , wherein the mixture has a moisture content ranging from about 30% to about 60% by weight of the mixture.

21 . The method of claim 9 , in which step (d) is performed at a temperature of about 100° C. to about 200° C.

22 - 23 . (canceled)

24 . A method for obtaining a treated protein material comprising:
(a) heating at least one source of animal proteins to a source of liver in a first vessel, thereby obtaining a pre-heated material; (b) separating the pre-heated material obtained in step (a) into a solid component (i) and a liquid component (ii); (c) drying the solid component (i); and (d) reintroducing the liquid component (ii) in the second vessel to the solid component (i); and (e) grinding of the dried mixture obtained in step (d) thereby obtaining a treated protein material.

25 . The method of claim 24 , wherein the source of animal proteins is selected from bones, carcasses, internal organs, necks or heads, or a combination thereof.

26 . The method of claim 24 , wherein the source of liver is selected from lamb liver, poultry liver, beef liver, pork liver, or a mix thereof.

27 . The method of claim 24 , wherein, at step (a), the animal liver is in an amount of about 5% by weight on a dry matter basis.

28 - 33 . (canceled)

34 . The method of claim 1 , wherein the method further comprises manufacturing a food composition for animal consumption comprising the following steps:
(I). mixing the protein material obtained according to the method with at least one ingredient suitable for preparing a food composition for animal consumption; and (II). treating the mixture obtained in step (I) to supply a food composition for animals.

35 . The method of claim 34 , wherein the at least one ingredient is selected from moisture, a source of fats, a source of ashes, a source of fibers, a source of carbohydrates, a source of EPA/DHA, a source of starch or a combination thereof.

36 . (canceled)
