抄録

The feasibility of using FT-Raman spectroscopy for rapid non-destructive determination of various pulp properties was examined using two Eucalyptus species, including samples of various ages and colors, which are of importance as a plantation source. Pulp properties, namely pulp yield, sheet density, burst factor, breaking length, tear factor, unbleached brightness and Kappa number were measured. The application of 2nd derivatives transformation of Raman spectroscopic data revealed highly significant correlations between measured and Raman predicted values for all traits with correlation coefficient (r) > 0.998 in the calibration (for known samples) and r > 0.882 in the prediction (for unknown samples), respectively. Consequently, this non-destructive method has proved its validity for analyzing Eucalyptus native wood meal samples, regardless of their age and color, to determine pulp properties. Use of this method will reduce the costs of tree improvement programs and reduce our reliance on natural forests; furthermore, the minimal sample size needed will allow trees to be non-destructively sampled.
