METHOD TO ALTER THE ISOMERIC PROFILE OF TRANS FATTY ACIDS IN RUMINANT MEAT AND MILK AND TO INCREASE THE CONCENTRATION OF CIS-9, TRANS-11 CONJUGATED LINOLEIC ACID
METHOD TO ALTER THE ISOMERIC PROFILE OF TRANS FATTY ACIDS IN RUMINANT MEAT AND MILK AND TO INCREASE THE CONCENTRATION OF CIS-9, TRANS-11 CONJUGATED LINOLEIC ACID
The present invention relates to methods for altering the fatty acidcomposition in milk or tissue fat directly derived from a milk producingruminant. The methods consist of administering to said milk producing ruminanta suitable amount of a chemical compound selected from the vitamin E family,or a structurally or functionally related compound or derivative thereof. Athigh doses, vitamin E influences ruminal biohydrogenation and allows theproduction of milk or tissue fat with a highly desirable fatty acid profile:high trans-11 C~18:1, high cis-9, trans-11 C~18:2 (CLA), low trans-10 C~18:1.Methods are disclosed to obtain said desirable fatty acid profile, therebyimproving the nutritional benefits to human health associated with CLA. Milkand tissue fat obtained by said methods are also disclosed. Dietary intakes ofcis-9, trans-11 C~18:2 CLA and trans-11 C~18:1 fatty acids in milk or meat, orproducts thereof, produced in accordance with the present invention inruminant animals, can be effective in preventing cancer in different sites,reduce risk of coronary heart disease and to enhance immune function.
