Selection of surfactant-modified lipases for interesterification of triglyceride and fatty acid

Interesterification of tripalmitin and stearic acid in n-hexane was investigated with surfactant-modified lipases. Various kinds of lipases and surfactants were screened for high interesterification activity of the modified lipases. The modified-lipase activity was influenced by both the lipases and the hydrophile-lipophile balance value and fatty acid group of the surfactants. The modified lipase obtained from Rhizopus japonicus with sorbitan monostearate as surfactant had the highest activity in the n-hexane system. The interesterification activity of the selected modified lipase in molten substrates at 75°C without solvents was the same as that in the n-hexane system at 40°C.
