Nanofiltration Membrane Low-Temperature Concentration Technology for Botanical Extract Processing

Traditional plant extract concentration mainly relies on vacuum evaporators, which require long-term high-temperature heating. The thermal processing easily causes oxidation, browning and activity loss of heat-sensitive natural active ingredients, resulting in low product quality and low material utilization rate. In addition, thermal concentration cannot remove micro-soluble impurities, leading to high moisture ash content and poor stability of finished extracts. Nanofiltration membrane separation technology adopts low-pressure physical interception to realize efficient water removal and synchronous purification of botanical extracts at room temperature. It concentrates effective components while removing partial small-molecule impurities, greatly improving product purity, color and yield. With the advantages of energy saving, no thermal damage and stable batch consistency, nanofiltration low-temperature concentration has become an indispensable core process in modern plant deep-proce
