Example 15
2001.6 grams of crude soybean oil containing 641.6 ppm of phosphorus was heated to 70° C. under normal agitation utilizing an overhead mixer. 2.0 grams of 50% w/w solution of citric acid was added and sheared for 1 minute. The oil underwent normal agitation for 1 hour with an overhead mixer. The oil was allowed to cool with agitation at normal speed until the oil temperature was 45° C., then 3.31 milliliters of 4 molar sodium hydroxide solution was added to the oil and mixed. 0.10 grams of Novozymes' Lecitase® Ultra (PLA1 lipase lot number LYN05015) was added followed by a total of 60 grams of de-ionized water and the entire mixture was shear mixed for 60 seconds. The oil mixture was agitated at normal speed for 240 minutes at a temperature of 45° C. The enzyme treated oil was then centrifuged; and the separated oil and wet gums were collected. The residual phosphorus in the PLA1 at a pH of 6.5 treated oil produced a degummed oil with a residual phosphorus of 3.4 ppm. The FFA was 0.51% and DAG was 0.33%. The collected wet gums weighed 88.7 grams.
