Traditional tangerine peel (Chen Pi) raw liquid suffers from turbidity and precipitation caused by colloids, pectin and macromolecular impurities, restricting its industrial application. Membrane separation technology realizes low‑temperature physical clarification for tangerine peel liquid. It removes colloidal impurities while retaining core active substances such as hesperidin and flavonoids. Compared with conventional filtration, this technology delivers high‑clarity golden filtrate, avoids thermal damage to ingredients, cuts consumable costs, and improves product stability and shelf‑life. The processed tangerine peel filtrate can be used for functional beverages, food flavorings, herbal intermediates and cosmetic raw materials. We provide customized membrane separation solutions for plant extract clarification.
