Evaluation of surfactant-aided degumming of vegetable oils by membrane technology

摘要: The first step in the process of vegetable oil refining is degumming, which phospholipids and mucilaginous gums are removed that otherwise result a low-grade oil. A membrane remarkably simple yet potentially offers many advantages degumming. Studies were conducted on surfactant-aided degumming with soybean rapeseed oils magnetically stirred flat batch cell different types microfiltration membranes. reduction was range 85.8–92.8% during process. phosphorus content permeates 20–58 mg/kg. Crude contained higher amount nonhydratable hence resulted lower phospholipids, 66.4–83.2%. Addition hydratable could improve efficiency without using any electrolyte, resulting improvement quality as well quantity phospholipids.
