Fractionation of sweet lupin protein and study of physicochemical and functional properties of obtained isolates in food systems

Sweet lupin seeds as rich source of protein with promising functional and nutritional properties have triggeredthe interest of the food industry for a number of years now. However, to date, these proteins have not yet beenexploited to their full potential in the food sector as a thorough characterization and functionality screening ofthe protein is lacking. Powell May International (PMI) is a Canada-based ingredient broker which would like toadd sweet lupin seed protein to its product portfolio. The objective of this project is, hence, to develop afood-grade isolation procedure for the sweet lupin seed proteins and a thorough characterization of the proteinisolate. The characterization involves a full physicochemical and functional study of the obtained isolates. Thisproject is a first step towards possible commercialization of an undervalued protein source that can be grown inOntario. The timeliness and importance of this project for Canada can be illustrated by the potential this projecthas in terms of (i) putting Canada-based PMI at the forefront of the international plant-based protein industryand (ii) higher valuation of a crop that can be incorporated in a crop rotation plan by farmers inCanada/Ontario. Furthermore, this project coincides with the greater demand of both industry as well asconsumers for alternative plant-based proteins with excellent nutritional properties.
