Abstract

Sugar-beet pulp was found to contain dehydrodimers of ferulic acid, which were characterized and quantified by GC and GC-mass spectrometry. These compounds arise from 8-5', 5-5', 8-8' and 8-O-4' coupling, the 8-5' form being preponderant; no 4-O-5' dimer was detected. Total dehydrodimers represented 0.14% (w/w) of the pulp. Their release was attempted by treatment of the pulp with a commercial pectinase. However, diferulates were resistant to this enzymic hydrolysis; free diferulic acids were not released and remained esterified to residual structures of the sugar-beet pectins.
