DOIAbstract
Enzymatic degumming trials were performed on crude extracted soybean (SBO) and rapeseed oils (RSO) with a microbial phospholipase A(1) (Lecitase Ultra (R)). We obtained a degummed oil with a phosphorus content<10mg/kg when applying an enzyme dosage of 30mg/kg and (feedstock dependent) a contact time of 10-120min. While a good degumming efficiency can already be obtained after a relative short reaction time, it was observed that a longer reaction time (1-2h) is required for complete degradation of the phospholipids (PL), which results in a yield increase. We demonstrated that Lecitase Ultra (R) has no specificity for a given PL, but that the rate of conversion depends on the PL composition of the crude oil. After 60min, 80% of phosphatidyl e...
