Food products containing proteins from plants, fungi or algae are becoming increasingly popular. Researchers at the Fraunhofer Center for Chemical-Biotechnological Processes CBP in Leuna, Germany, have now shown that previously rarely used rapeseed proteins are also a valuable source of protein alternatives: using the EthaNa process, they extract not only high-quality rapeseed oil from rapeseed but also a protein-rich rapeseed kernel concentrate, which can be processed for instance into burger patties and pasta or used as a nutritious feed in poultry fattening.
