Phytic Acid Purification & Concentration by Membrane Separation Technology
Phytic acid is mainly extracted from rice bran and grain by‑products. Conventional processes such as plate‑and‑frame filtration and thermal evaporation suffer from incomplete impurity removal, thermal degradation of active components, high energy consumption and unstable product purity. Membrane separation works at ambient temperature via physical sieving. Ultrafiltration removes colloids and protein impurities, while nanofiltration realizes concentration and desalination simultaneously. It improves clarity, purity and recovery rate, becoming a preferred solution for food‑grade and pharmaceutical‑grade phytic acid production.

Nanofiltration Membrane Technology for Chinese Herbal Extract Refining and Purification
Traditional Chinese medicine extraction liquid contains complex impurities such as plant pectin, macromolecular protein, tannin, residual starch and inorganic salts after water and alcohol extraction. Traditional purification methods including alcohol precipitation, resin adsorption and vacuum concentration have the disadvantages of high reagent consumption, long process cycle, serious active ingredient loss and high energy consumption, which cannot meet the production standards of high-purity and high-stability herbal finished products. Cross-flow nanofiltration membrane technology realizes physical impurity removal, desalination, decolorization and low-temperature concentration through precise molecular screening. It effectively removes invalid macromolecular impurities and small-molecule heterologous substances while fully retaining heat-sensitive active ingredients. This green and efficient separation process has become the core refining technology for modern Chinese medicine deep-
