Abstract: The invention relates to using substantially insoluble vegetable fibres embodied in the form of microparticles at least 90% in weight of which has a size less than 700 ?m as ingredients for preparing a nutritional composition for reducing a mycotoxin bioavailability in a human being or an animal during ingestion of a food contaminated by said mycotoxins.

Abstract: The ivention concerns a biological method for decontaminating mycotoxins present in a liquid food product by adsorbing them onto insoluble vegetable fibers, and a brewing method comprising at least one decontamination step according to said method, as well as food products at least partly detoxified obtained by implementing said method.

Abstract: The present invention relates to methods for altering the fatty acid composition in milk or tissue fat directly derived from a milk producing ruminant The methods consist of administering to said milk producing ruminant a suitable amount of a chemical compound selected from the vitamin E family, or a structurally or functionally related compound or derivative thereof. At high doses, vitamin E influences ruminal biohydrogenation and allows the production of milk or tissue fat with a highly desirable fatty acid profile: high trans-11 C18:1, high cis-9, trans-11 C18:02 (CLA), low trans-10 C18:1. Methods are disclosed to obtain said desirable fatty acid profile, thereby improving the nutritional benefits to human health associated with CLA. Milk and tissue fat obtained by said methods are also disclosed.
