A novel process for simultaneous degumming and deacidification of Soybean, Canola and Sunflower oils by tetrabutylphosphonium phosphate ionic liquid

摘要

In this study simultaneous degumming and deacidification of edible oils were done by tetrabutylphosphonium phosphate IL. Under the optimized extraction conditions of soybean oil (3 mass% IL, 60 degrees C and 20 min), canola oil (2 mass% IL, 60 degrees C and 20 min) and sunflower oil (1.5 mass% IL, 50 degrees C, 15 min), the content of free fatty acid (FFA) and phosphorus reached 0.18% and 3.5 mg/kg; 0.12% and 3.8 mg/kg; and 0.17% and 3.5 mg/kg, respectively. In this work, soap stock and water washing stage were eliminated and no waste water, which pollutes the environment, was produced. (C) 2019 The Korean Society of Industrial and Engineering Chemistry.
