Report: Phospholipase for enzyme-assisted alkaline refining


Published in Inform January 2021, Vol. 32 (1)

Phospholipase C (PLC) products have been on the market for several years already and are well- established in the water degumming of soybean oil to provide additional oil yield (Galhardo and Dayton).

While developing the new PLC Quara® Boost for water degumming, Per Munk Nielsen and his research group discovered that the enzyme could be integrated with the alkaline refining process. The result is a significant increase in oil yield and preservation of the final oil quality from caustic refining (Holm and Nielsen). Recently, the process efficiency has been confirmed in full-scale trials.
