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.

甜羽扇豆种子作为丰富的蛋白质来源，具有良好的功能和营养特性，多年来一直受到食品工业的关注。然而，迄今为止，这些蛋白质尚未被充分利用其在食品领域的潜力，因为缺乏对蛋白质的彻底表征和功能筛选。Powell May International（PMI）是一家加拿大的配料经纪商，希望将甜羽扇豆种子蛋白添加到其产品组合中。因此，本项目的目标是开发甜羽扇豆种子蛋白的食品级分离程序和蛋白分离物的彻底表征。表征涉及对获得的分离株进行全面的物理化学和功能研究。这个项目是一个可能的商业化的第一步被低估的蛋白质来源，可以在安大略省种植。该项目对加拿大的及时性和重要性可以通过该项目的潜力来说明，该项目（i）将加拿大的PMI置于国际植物蛋白产业的前沿，（ii）提高加拿大/安大略农民可纳入作物轮作计划的作物价值。此外，该项目符合行业和消费者对具有优异营养特性的替代植物蛋白质的更大需求。
