Immobilisation of lecitase® ultra for production of diacylglycerols by glycerolysis of soybean oil

► Lecitase® ultra was immobilised as a catalyst for glycerolysis of soybean oil. ► The immobilised lecitase® ultra (IM-LU) had a high activity in production of DAG. ► IM-LU performed a good performance of reusability when being recycled 28 times. ► IM-LU possessed sn-1, 3-specificity to triacylglycerols in glycerolysis reaction.
