New method efficiently separates proteins from agrobiomass by-products – particularly brewer's spent grain (BSG)
According to research by VTT Technical Research Centre of Finland, extraction with deep eutectic solvents (DESs) offer an efficient, sustainable and easy method for dissolving proteins from agrobiomass by-products. DESs are mixtures of solids that form a liquid solution at low temperatures when mixed in suitable ratios. The method has been tested on separating protein from BSG, rapeseed press cake and wheat bran, all of which contain significant amounts of protein. These food industry by-products contain significant amounts of fibre, which decreases their suitability as feed for
