Abstract:

Lipase is a kind of enzyme that can catalyze interesterification in a non-aqueous system. Stability of lipase is important in practical applications because of its effection of the production cost and efficiency. To understand the influence of different factors on catalytic stability of lipase, the effects of temperature, time, solvents and acyl donor on stability of lipase interesterification are studied. The results show that the effects of temperature and solvent polarity on catalytic stability of lipase are significant. But the effects of time and acyl donor are not obvious.

Key words: interesterification, stability, lipase
