Abstract

The present invention relates to the method of producing an antimicrobial composition characterized in that it comprises the steps of: a) splitting an lauric oil treated with activated carbon; and b) recovering a composition comprising 90% or more, by weight of free fatty acids. The invention further relates to antimicrobial compositions obtained by said process, to feed, food or beverage comprising said composition and to their uses.

First claim

1 .- 14 . (canceled)

15 . A feed, food or beverage composition comprising in an amount of 0.05-10% by weight an antimicrobial composition, wherein the antimicrobial composition comprises 90% or more, by weight, free fatty acids (FFAs), the FFAs comprising, by weight, 0-5% C6 fatty acids; 1-15% C8 fatty acids; 1-15% C10 fatty acids, and 35-70% C12 fatty acids; having a level of 20 parts per billion (ppb) benzo(a)pyrene (B([a]P) or less, and devoid of burnt, taste and smell.

16 . The feed composition according to claim 15 , suitable for use with calves, porcine animals, rabbits, poultry, domestic animals, and aquatic animals.

17 . The feed composition according to claim 15 , suitable to enhance feed efficiency in animals.

18 . The feed composition according to claim 15 , suitable to enhance growth in animals.

19 . The feed composition according to claim 15 , suitable to reduce mortality in animals.

20 . The feed composition according to claim 15 , wherein the antimicrobial composition has a 2,3,7,8-tetrahloro-dibenzodioxin (TCDD) content no greater than 1.5 ppb.

21 . The feed composition according to claim 15 , wherein the antimicrobial composition comprises 95% or more FFAs by weight.

22 . The feed composition according to claim 15 , wherein the antimicrobial composition has a level of 10 ppb B[a]P or less.

23 . The feed composition according to claim 15 , wherein the antimicrobial composition has a level of 4 ppb B[a]P or less.

24 . The feed composition according to claim 15 , wherein the antimicrobial composition has a level of I ppb B[a]P or less.

25 . The feed composition according to claim 15 , wherein the antimicrobial composition has a total polycyclic aromatic hydrocarbon (PAH) level of 3 ppb or less.

26 . The feed composition according to claim 15 , wherein the antimicrobial composition has a total PAH level of 0.3 ppb or less.

27 . The feed composition according to claim 15 , wherein the antimicrobial composition has a toxicity equivalence (TEQ) B[a]P of 20 or less,

28 . The feed composition according to claim 15 , wherein the antimicrobial composition has a TEQ B[a]P of 10 or less.

29 . The feed composition according to claim 15 , wherein the antimicrobial composition has a TEQ B[a]P of 1.5 or less.
