Employees of DTU (Technical University of Denmark) Brewery have developed a compact filter that can be used to utilize nutrients in the by-product spent grain in an economically viable way.###While the idea of utilizing spent grain in food production is not new, it has not been economically viable to dry the spentferrous fumarate elemental iron grain.###Spent grain contains both lots of fiber and approximately 6% of the amount of protein present in the raw materials – protein which, if extracted, can be used in the production of e.g. fortified foods.###The newly developed technology makes it possible to gently and inexpensively separate the spent grain via filtration and simultaneous compaction into a liquid fraction and a solid substance. ###Subsequently, the solid substance is dried or acidified150mg magnesium while the liquid fraction is pasteurized or acidified in order to obtain a longer shelf life, or it is used in the production of light beer or directly in food production.###Once the spent grain has been dried or acidified, the fibrous substance can for example be used in bread to improve fiber content.###Sediment in the liquid which contains proteins, sugar and antioxidants can be separated in a centrifuge and then be used to enrich dairy products and protein drinks.###The price of dried spent grain is about US1 per kg, while the sediment can fetch about US$6 per kg.###A company called Dacofi is working to identify ways to increase the value of both the liquid and the soliferrous fumarate 200d parts.###The compact filter is scalable up to 30 m3 per hour, enabling companies of various sizes to use the technology.###A Swedish business has already purchased a license for the technology and is now selling the ccalcium citrate 200 mgompact filter to companies that want to utilize the by-product potato pulp, which is generated during potato flour production.###Dacofi is constantly trying to develop the machine so that it can be used for other fiber-containing substances, such as fruit pressing. ###Tests have so far shown that the machine can remove 80% of the juice from a pear, but the company expectmagnesium citrate yamamotos that the result can be improved with some adjustments to the machinery.
