A method to obtain a protein-rich lupin flour, a protein-rich lupin flour and its uses thereof

Abstract

The invention relates to a process for producing a protein-rich lupin flour, said process comprising the successive steps of a) washing a lupin flour by mixing it with an acidic aqueous liquid, and adjusting the pH of the mixture to a pH ranging from 3.5 to 5.3, to obtain a aqueous-washed lupin flour; and b) washing said aqueous-washed lupin flour by mixing it with an alcohol at least one time, to obtain an alcohol-washed lupin flour. The invention further to a protein-rich lupin flour, wherein said protein-rich lupin flour comprises at least 45% DM w/w of proteins and at least 20% DM w/w of total fibres and may have a white or off white colour determined in the colour space CIELAB (1976) by a b* value of less than 18, preferably less than 17.4, preferably less than 15.0 and more preferably less than 12.0.
