Description
Aslı Arslan Kulcan examines, in a 2026 study, whether membrane filtration can split red beetroot juice into a health-rich concentrate and a sugar stream. Beetroot is prized for betalain pigments and phenolic compounds, yet its natural sugars limit some uses, so separating the two fractions has commercial appeal.
Ultrafiltration through two pore sizes came first; the tighter membrane held back more phenolics and betalains. Washing the retained fraction with added water — diafiltration — then flushed out small sugar molecules. At the best wash volume, recoveries reached about sixty-nine percent for phenolics and seventy-three percent for betalains, while under a fifth of the sugar stayed behind. The author presents the combined process as a route to enriched beetroot ingredients.
