Potential of Goniothalamus velutinus wood for agri-food industry

Abstract

Goniothalamus velutinus is from the family of annonaceae and it is native to Borneo. It is also known as “kayu tas” or “kayu hujan panas”. This type of wood is rarely encountered and also hard to find in the forest. It grows in the shady primary rainforest of tropical Asia, and approximately 160 species of this genus have been discovered. This plant is also known to have anti-cancer, anti-tumour and many other bioactivities. In this study, the Goniothalamus velutinus wood’s potentials were explored for the agri-food industry. The objectives of this study are to determine chemical composition of Goniothalamus velutinus and the functional group of two samples which are male tas (MT) and female tas (FT). The chemical compositions were determined by the Technical Association of the Pulp and Paper Industry (TAPPI) method, and the functional group analysis were determined by Fourier Transform Infra-red Spectroscopy (FT-IR). The results shows that male tas (MT) showed a higher chemical composition compared to the female tas (FT) such as for extractive; 4.73% and 2.21%, Holocellulose; 92.19% and 88.96%, Cellulose; 57.02% and 55.88%, Hemicellulose; 35.16% and 33.08%, Lignin; 27.48% and 34.46%, respectively. These chemical compositions have good potential for the food sector. For FT-IR analysis, the results revealed five different functional groups related to which chemical composition in the sample, especially cellulose.
