Application of Membrane Separation Technology in Zanthoxylum Bungeanum Oil Refining: Resolving Turbidity and Precipitation While Preserving Natural Numbing Aroma

Membrane separation overcomes bottlenecks of conventional prickly‑ash oil refining. It completes impurity removal, degumming and clarification under ambient temperature. The technology solves quality issues including turbidity and precipitation, preserves authentic fresh‑numbing aroma, raises oil yield and reduces solid waste and wastewater. It provides an efficient and modern process for deep processing of Zanthoxylum bungeanum oil.
