A novel approach is reported for the synthesis of dihydrocaffoylated glycerols that consists of two steps: enzymatic synthesis of octyl dihydrocaffeate (as a synthetic intermediate) from octanol and dihydrocaffeic acid, and enzymatic interesterification of triacylglycerols with octyl dihydrocaffeate. Due to the good compatibility of the intermediate with triacylglycerols, an improved volumetric productivity [147 mol h−1(kg Novozym 435)−1] and high enzyme specific activity [up to 9.6 μmol−1 min−1(g Novozym 435)−1] have been obtained.
