Abstract

The present invention relates to bovine milk fat comprising, based on total fatty acid content, 8.9-29.0 wt % linoleic acid (C18:2 cis, 9,12), 0.9-2.4 wt % alpha-linolenic acid (C18:3 cis 9,12,15), and 3-5 wt % butyric acid (C4:0). The present invention further relates to a bovine milk comprising said milk fat and to a method for producing said milk by feeding a lactating bovine mammal with a rumen-protected linoleic acid source and a rumen-protected alpha-linolenic acid source, followed by milking the lactating bovine animal.

First claim

The invention claimed is:

1. Bovine milk fat comprising, based on a total fatty acid weight;
a. 8.9-29.0 wt % linoleic acid (C18:2 cis, 9,12),
b. 0.9-2.4 wt % alpha-linolenic acid (C18:3 cis 9,12,15), and
c. 3-5 wt % butyric acid (C4:0),
wherein a weight ratio of linoleic acid to alpha-linolenic acid is in a range of 4:1-10:1.

2. Bovine milk fat according to claim 1 , wherein the weight ratio of linoleic acid to alpha-linolenic acid is in a range of 5:1-10:1.

3. Bovine milk fat according to claim 1 , comprising 11-20 wt % linoleic acid, and preferably 12-18 wt % linoleic acid, based on total fatty acids.

4. Bovine milk fat according to claim 1 , comprising 15-40 wt % palmitic acid (C16:0).

5. Bovine milk fat according to claim 4 , wherein at least 30% of the palmitic acid is bound to glyceride at the sn-2 position.

6. Bovine milk fat according to claim 1 , comprising 8-18 wt % stearic acid (C18:0).

7. Bovine milk fat according to claim 1 , having an oleic acid content (C18:1 cis) in the range of 15-35 wt %.

8. Bovine milk fat according to claim 1 , wherein the fat comprises at most 3.0 wt %, preferably 0.5-3.0 wt %, and most preferably 0.5-2.5 wt % fatty acids with one or more non-conjugated carbon-carbon double bonds in the trans position.

9. Bovine milk fat according to claim 1 , having a soap forming potential defined as the molar percentage of the sum of C12:0, C14:0, C16:0, and C18:0 in the sn-1 or sn-3 position, based on total fatty acids of 55 mol % or less, preferably in the range of 30-52 mol %, in particular in the range of 40-50 mol %.

10. Bovine milk wherein the fat phase consists of the bovine milk fat according to claim 1 .

11. Bovine milk according to claim 10 wherein at least 50 wt %, preferably 90-100 wt. % of the bovine milk fat is globular milk fat.

12. Formula milk comprising a fat phase, wherein the fat phase consists of at least 50 wt. %, preferably at least 60 wt %, more preferably at least 70 wt %, even more preferably at least 90 wt %, and most preferably 100 wt % of the bovine milk fat according to claim 1 .

13. The formula milk of claim 12 , wherein the formula milk is an infant formula, a follow-up formula, or a growing-up formula.
