Glyceryl ferulate was synthesized by the condensation of ferulic acid with glycerol using Pectinase PL "Amano" from Aspergillus niger, which contained ferulic acid esterase, to improve the water-solubility of ferulic acid. The optimum reaction medium was glycerol/0.1 M acetate buffer, pH 4.0, (98:2 v/v). The enzyme immobilized onto Chitopearl BCW3003 exhibited the highest activity among the those immobilized onto various kinds of Chitopearl BCW resins. The optimum temperature for the immobilized enzyme was 50°C, and it could be reused at least five times without a significant loss in activity for the synthesis of glyceryl ferulate in batch reaction. Storage of the reaction mixture at 25°C improved the molar fraction of glyceryl ferulate relative to the dissolved ferulic residues.
