 We start our journey in a blooming rapeseed field in Poland. Rapeseed fields can be seen growing in countryside throughout the world. Rapeseed, also known as canola, is a raw material that has mainly been used for oil processing and animal feed. But did you also know rapeseed can also be a source of protein? After harvesting, rapeseed is pressed to make oil which is commonly used in our kitchens. Rapeseed cake is a byproduct of the pressing of oil, and well, it isn't your traditional cake that comes out of the oven. The natural-based process for turning rapeseed into protein involves several steps, including extraction, mechanical separation, filtration, and finally drying. The technique can be used by oil seed producers that currently process rapeseed for oil in rapeseed cake. Currently, the process is in the scale-up phase and will later be usable for large-scale production. Rapeseed cake is a sustainable source of protein. For those sensitive to allergies, rapeseed protein could be a valuable protein alternative. The startup company Napaferrin has been using bio-circular technology to make the most of rapeseed cake, transforming it into two types of powder, one which is protein and the other containing fiber. By using food tech, rapeseed can be a sustainable plant-based food protein source. It also has the benefits of having no smell or flavor, making it a practical ingredient for various food products like granola, protein bars, bread, or meat substitutes. Moreover, it can be used as a plant-based protein substitute for egg whites and meringues, or in the mayonnaise that you put on your sandwich. Would you give rapeseed protein a try?
