Rapeseed protein fractions. III. The nutritive value of a detoxified protein concentrate prepared from rapeseed (Brassica napus L.) by hydraulic processing

• A method is described for the hydraulic pressing of dehusked rapeseeds, resulting in a meal with comparatively low oil and crude fibre contents. This process was followed by repeated washings with water in order to remove the thioglucosides. The weight gain and the protein efficiency ratio in the rat was equal to that obtained with a reference diet based on methionine-enriched casein. The value of using hydraulic processing in order to prepare a protein concentrate from oilseeds for human consumption is discussed.
