In the quest to develop sustainable foods, which can feed the world’s growing population, researchers from the National Food Institute, Technical University of Denmark, together with AU Foulum have developed a method to extract protein from grass, so it can be used as a source of food.###The amino acid composition of grass protein is similar to that of other protein sources such as soy, eggs and whey. ###However, producing grass protein has a considerably smaller impact on the environment and climatebluebonnet calcium magnesium d3.###Extracting grass protein###The first step involved in extracting the protein is to feed the grass through a screw press, which acts as a huge juicer. ###It separates the raw material into a fibrous, dry fraction and a protein-containing liquid fraction. ###A subsequent treatment of the liquid fraction separates out the protein, which is then dried into a powder.###The extracted protein powder can fetch a kilo price, which is approximately 10 ticalcium citrate foodmes higher than if the raw material was sold as feed. ###Furthermore, the dry fraction can still be sold as cow feed, which increases the overall profitability and sustainability of the concept.###Grass must not taste of grass###So far the National Food Institute has managed to produce products such as protein bars that contain up to 10% grass protein without people wrinkling their nosferrous gluconate 250 mg elemental irone at the taste. ###This is done by removing some of the grass taste or adding aromatic ingredientsmagnesium citrate for muscle cramps such as peanut butter, honey, ginger and liquorice, which help to camouflage the grass taste.###The next step is to remove even more flavor and color from the protein powder, and test the protein’s properties in a wide range of food products. ###The work is part of the innovation project BioValue, where DTU, University of Cfumarate supplementopenhagen, Aarhus University and Aalborg University work with a number of businesses to find innovative ways to better utilize the green biomass.###Story by Miriam Meister, DTU
