Starch & Protein Sidestreams

When extracting proteins from vegetable-based raw materials, several different components are produced (such as protein isolates/concentrates, starch and fibers). The resulting effluent or runoff water is often considered to be a waste stream. Yet, it could actually be a valuable source of additional products with considerable nutritional value. GEA can work with you to expand the potential of your sidestreams and recycle that so-called wastewater.
