  • Does top degumming reduce phosphorus in rapeseed oil?
  • Zufarov et al., (2008) studied the effect of water, acid, and Totaal Ontslijmings Process (TOP) in rapeseed and sunflower oil. They reported that acid and TOP degumming reduced the phosphorous content to the desired level, but more neutralized oil loss was lost in the gum. ...
  • Does enzymatic degumming reduce phospholipids in crude sunflower oil?
  • The phospholipids content of crude sunflower oil was strongly reduced by the enzymatic degumming process being 95.05% and 94.28% with PLA1 and PLA2 respectively. This should be due to the hydrolysed capacity of the enzymes. The water degumming process also achieved a significant reduction in the phospholipids content.
  • What is the difference between water degummed and crude oil?
  • Crude oil, either water degummed or not, is treated by an acid, usually phosphoric acid, citric acid or malic acid in the presence of water. For oils containing relatively low amounts of NHP (e.g. sunflower oil) this process can lead to degummed oil with a lower residual phosphorus content (5 to 30 ppm) than water degumming.
  • Does water degumming reduce the iron content of crude sunflower oil?
  • As well, the iron content of crude sunflower oil was reduced to 4.15 mg/kg after degumming using the PLA2 enzyme. The results obtained also indicated that water degumming process reduced the content of this metal. This may indicate that a significant iron concentration was complexed with phospholipids ( Brevedan et al., 2000 ).
  • Does pH affect rapeseed oil degumming performance?
  • An enzymatic degumming plant trial was performed on a 400 tons/d oil production line. pH was found to play an important role in degumming performance. When the pH was 4.6–5.1, the corresponding phosphorus content of degummed rapeseed oil could be reduced to less than 10 mg/kg, which met the demands of the physical refining process.
  • Which degumming process is not suitable for oil refining?
  • Traditional degumming that include water, super, total, acid degumming and ultrafiltration processes cannot guarantee the low phosphorus levels that are required for physical refining ( Jiang et al., 2015 ). These techniques are not suitable for oils with high levels of non-hydratable phospholipids ( Zufarov et al., 2008 ).
