Starch hydrolysates are in the form of glucose syrups obtained after hydrolysis and with a brownish/yellowish colour caused during processing and preservation. Activated carbon (AC) adsorption is the most used method for decolourising glucose syrups. It is responsible for high costs leading to significant AC consumption and a waste product that needs to be appropriately disposed of and treated. This work evaluated the decolourisation of starch hydrolysates, using AC in combination with Ultrafiltration (UF) to develop a cost and resource-effective downstream process in the future.
