Chemical characteristics and utilization of oil palm trunks.
1992
Tomimura Y.
Chemical characteristics of oil palm trunks were investigated to find out the best utilization way. Oil palm trunk tissue consists mainly of vascular bundles and parenchyma cells, which are separated easily and discriminately from each other by mechanical crush. Starch content was remarkably high in parenchyma cells. Xylose and glucose were the main sugar components in both tissue, indicating that the polysaccharide consists of xylan, starch, and cellulose. Lignin content was less than 20% in both fractions. The lignin of oil palm contained p-hydroxybenzoic acid as an ester group which could easily be removed by alkaline treatment. Oil palm trunks have a high potential for food and cattle feed production due to the high contents of xylan and starch in addition to cellulose and lignin. The p-hydroxybenzoic acid could be used as a raw material for engineering plastics. Oil palm trunks have a great potential for its utilization in the course of processing for cattle feed production.
