Need for "alternative" proteins
Proteins are essential for human and animal nutrition. Climate change and environmental pollution pose new challenges for protein production. Protein sources from plants, algae, insects and fungi offer an alternative to animal-based foods. In the FutureProteins lighthouse project, Fraunhofer is therefore pursuing the goal of developing pioneering technologies for agriculture and the food industry.
Fermentative production of proteins
Proteins of non-animal origin are becoming increasingly important due to growing consumer demand for vegan foods. Milk proteins and other proteins of high nutritional value can also be produced by fermentation, for example. Please contact us if you are interested!
High-quality rapeseed proteins for nutrition
The mild process conditions of the EthaNa process, for which a pilot plant was built at Fraunhofer CBP (see below: Oilseed biorefinery), produce a rapeseed concentrate rich in high-quality, non-denatured proteins during the extraction of rapeseed.
The EthaNa rapeseed concentrate is free from hulls and secondary plant substances and contains only very small amounts of undesirable tannins and bitter substances. The high protein content of currently 42-43 percent corresponds approximately to that of cold-pressed, partially dehulled rapeseed cake from decentralized oil mills. The non-denatured proteins are easily soluble in water and can therefore be extracted and used as an alternative vegetable protein source in meat substitute products, for example. The EU project Like-a-Pro is researching how rapeseed concentrate can be used as a source of protein for the production of foodstuffs.
Rapeseed concentrate can also be used as a high-quality animal feed: it is low in glucosinolates and contains only a small amount of fiber.
