Comparison of dead-end ultrafiltration behaviour and filtrate quality of sugar beet juices obtained by conventional and “cold” PEF-assisted diffusion

► PEF-assisted “cold” diffusion results in low concentration of foulants in the diffusion juice. ► This juice yields filtrate with higher purity and lower coloration. ► Membrane MWCO has great impact on the filtrate purity and coloration. ► Formation of polarised layer has minor effect on colorants retention.
