PROCESS FOR THE PREPARATION OF FERMENTATION MEDIA ALLOWING TO PRODUCE YEAST FOR ANIMAL FEEDING AND MICROSPORES AND / OR TO PRODUCE PROTEINS FROM PLANT WASTE

Номер: FR2384843A2

La présente addition concerne un procédé de préparation de milieux de fermentation permettant de produire de la levure pour l'alimentation animale et des microspores et/ou de produire des protéines à partir de déchets végétaux. Selon ce procédé, à partir de divers déchets végétaux, constituant les principales matières premières, on obtient des hydrolysats partiellement acides permettant de produire de la levure pour l'alimentation animale, et des extraits partiellement alcalins à partir desquels on peut facilement séparer, de préférence par traitement acide, la presque totalité du contenu protéinique des produits bruts végétaux. Application à la production d'aliments pour animaux. The present addition relates to a process for preparing fermentation media making it possible to produce yeast for animal feed and microspores and / or to produce proteins from plant waste. According to this process, from various plant wastes, constituting the main raw materials, partially acid hydrolysates are obtained making it possible to produce yeast for animal feed, and partially alkaline extracts from which can easily be separated, preferably by acid treatment, almost all of the protein content of raw vegetable products. Application to the production of animal feed.
