Membrane Separation for Resveratrol Purification

Resveratrol is a heat-sensitive polyphenol antioxidant widely sourced from botanical raw materials. Traditional thermal concentration tends to destroy its active structure and lower product yield. Membrane separation technology provides an effective low-temperature purification route for resveratrol production. Combined tubular ultrafiltration and nanofiltration processes remove macromolecular impurities and concentrate target components without phase change. Tubular membrane equipment features strong anti-fouling performance, suitable for viscous plant extracts. Small and mid-pilot membrane systems enable parameter testing and process optimization. This technology reduces energy consumption, improves resveratrol recovery and purity, and supports clean manufacturing for nutraceutical and cosmetic raw material production.
