Green biomass offers a huge and not yet explored potential for the production of protein for feeds and foods. With a view to examining the possibilities of utilizing this potential, Aarhus University has established a research platform focusing on the extraction of protein from clover, lucerne/alfalfa and grasses. The platform includes laboratory facilities for the extraction and analyses of fractionations of protein and other high-value components. In addition, a pilot plant for large scale extraction has been built. This plant includes equipment for all processes ranging from pressing fresh biomass, e.g. grass, to the final products such as pulp and juice.
The pulp consists of fibres and fibre-bound protein, which is very suitable as ruminant feed. The juice has a high content of soluble protein to be utilized by pigs and poultry. In connection with an optimization of extraction procedures, feeding and digestibility experiments with both ruminants and monogastrics will be performed.
