The present invention relates to the selective extraction of proteins over oil from oil seed meal, preferably from cold pressed oilseed meal, for the purpose of producing protein isolates composed of native proteins. More specifically, the invention describes a method for producing from oil seed meal an intermediate aqueous protein solution having a fat to protein ratio of at least 1:12 comprising subjecting oil seed meal to aqueous extraction under minimal shear conditions and optionally collecting the resulting intermediate aqueous protein solution.
