Value Addition of Wild Madan Tree (Garcinia fusca Pierre) in Sisaket, Thailand

摘要

Wild madan tree is a native fruit tree commonly found along the river banks in Sisaket, Thailand. The wooden stick from tree stem has been traditionally used as a chicken skewer since over 50 years. The community earns about 1.5 million baht per yearfrom the madan skewer production. This enterprise generates a lot of peeled wild madan bark as a by-product. The present investigation was aimed at assessing whether natural dyes can be extracted from wild madan tree (used traditionally as chicken skewer) bark. Employing four mordants to intensify the colour of the extract, it was concluded that dyeing three times with dye from fresh bark resulted in highest percentage (68) of satisfaction. Thus, using wild madan tree bark for dyeing cotton cloth wouldprovide additional incentive to farmers for conserving this nature fruit tree.
