Optimized protein extraction and purification
In order to optimize the extraction of proteins, researchers at Fraunhofer IGB digest fungi and microalgae using pressure change technology. Thus, by utilizing various methods, they separate solid and liquid fractions into their individual components, which can either be processed into protein products or be returned to cultivation processes.
Closed-loop agriculture enables cost-effective recycling of by-products
The FutureProteins project is implementing a closed-loop of material and energy flows in all cultivation systems. At the IGB, process water is treated for reuse, and nutrients are recovered for new cultivation cycles. This means that any by-products of the cultivation process will be put to valuable use, e.g. as a substrate for cultivating insects, fungi or algae.
Product manufacturing: high-quality foods from alternative protein sources
Each of these alternative protein sources display different sensory and functional properties. Researchers are seeking for specific extraction and modification processes in order to optimize protein properties. Another important research task is to develop recipes for appetizing foods that will have high consumer acceptance.
Sustainability assessment and maximization of closed-loop recycling
In addition, the closed-loop agricultural systems and protein extraction methods developed for this project will be assessed to determine whether they make better use of resources and are more sustainable than conventional methods. A further aspect of this cross-institute project will be to ensure maximal closed-loop recycling of the materials and energy used in such systems.
