degumming of vegetable oil by a new microbial lipase

Abstract

Lecitase® Ultra lipase is an acidic lipase which exhibits maximal activity at pH=5.0. It takes part in the activity towards both phospholipid and triglyceride structures. When the temperature is over 40 °C, the phospholipase activity predominates, and the lipase activity is partly suppressed. It could be applied for the degumming of vegetable oil, and the phosphatides in the oil were easily converted by enzymatic catalyzed hydrolysis to less than 10 mg/kg within 5 h at 50 °C.
