In Europe, more than 60% of the starch production is based on com as raw material. Corn has a comparatively high protein content of approx.12%.The processing technologies in the corn starch production industry has undergone an intensive development in the last decades. Protein is now extracted from production waste streams in several factories in Europe. The currently used method is acidic heat coagulation at pH 4,5 and 110°C, which has a very high-energy consumption per kg of produced protein. The aim of this project is the development of a competitive process for the extraction of protein suitable lord human consumption from corn based on an innovative combination of micro-milling and membrane separation technology. The research approach in this project is to improve and extent the integrated processing chains in the cornstarch industries, with a special focus on reduction of energy and fresh water in protein extraction.
