ECOLOGICAL METHOD FOR IMPROVING THE AVAILABILITY OF ACTIVE SUBSTANCES FROM PLANT MATERIALS, USE IN ANIMAL FEED AND FOOD COMPOSITION

摘要

The present invention relates to a process for improving the availability of an active substance contained in a plant raw material comprising the following steps:(a) have at least one vegetable raw material;b) performing an impregnation step by contacting said raw material with a polar solvent for a period ranging from 1 hour to 2 days at a temperature ranging from 5 ° C to the boiling point of the polar solvent;c) proceeding with the partial evaporation until obtaining a product comprising from 5 to 50% by weight of solvent,said method being such that the step of evaporating the solvent is carried out directly on the entire mixture. It also relates to the product obtainable by this process, a composition containing said product and the use of said product in animal feed.
