摘要： A method for flocculation of root or tuber juice is described having the advantage that dissolved protein remains unaffected and that clear potato juice with an OD620 below 0.8 is obtained. This is important for applications in which soluble protein is to be extracted from root or tuber juice, because it increases lifetime of the used equipment. The method involves a) use of a coagulant comprising a cationic coagulant and a flocculant comprising an anionic polyacrylamide with a specific viscosity of 4-6 mPa·s and a charge density between 45 and 75%; or b) use of a coagulant comprising a polymeric silicate of formula SiO32− and a flocculant comprising a cationic polyacrylamide with a specific viscosity of 3-5 mPa·s and a charge density of at most 30%; or c) use of a coagulant comprising a cationic or neutral coagulant and a flocculant comprising carrageenan. The invention further provides valuable root- or tuber derived materials, such as the floc material, a potato lipid isolate or an amino acid material.
