Acetylation of STLs from chicory root 10 mM of Lc (2.76 mg), DHLc (2.78 mg), Lp (4.10 mg) or DHLP (4.12 mg) and 100 mM of vinyl acetate (8.60 mg, 9.22 µL) were dissolved in the solvent mixture in the presence of 3 Å molecular sieves. 1 mL of the resulting solution was introduced into a 2 mL vial containing 20 mg of Novozym 435 and 3 particles of 5 Å molecular sieves. The vials were placed in an orbital carousel rotating shaker (Thermo Scientific Tube Revolver) at 35 rpm in an oven at 37 °C for 48 h. The reaction mixtures were then filtered on 0.2 µm PFTE filter into 2 mL Eppendorf tubes and concentrated under 8 mbar at 35 °C in a Thermo Scientific SpeedVac system for 2 h until dry.
