Abstract

The FT-IR ATR spectra of the alkaline and enzymatically treated hemp fibres (1%, 2%, 3% o.w.f. enzyme,
15, 35, 55 minute enzyme action time) were recorded aiming to evaluate the pectin elimination. The relative absorbance
values of the 1732 cm-1 band which might be attributed to the presence of the carboxylic groups (C=O) in pectin were
evaluated. The results showed a diminishing of the pectin amount with increasing concentration (% o.w.f.) and action
time (minutes) of the enzyme mixture. So that, the absorbance recorded at 1732 cm-1 with FT-IR ATR spectroscopy can
quantify removed pectin from the material, thus enabling characterization of proposed biotechnology and monitoring the
process.
