The purpose of neutralizing is to remove free fatty acid, phospholipids, gums or solids in edible oil by using caustic soda. We offer solutions featuring higher oil yield and lower energy consumption. Bleaching process removes coloured matters, residual pesticides, metal ions by mixing bleaching earth with edible oil.
How is edible oil processed?
