Study on pretrreatment of gaharu oil extraction process

Gaharu, the names for the resinous, fragrant and highly valuable heartwood produced by Aquilaria Malaccensis. Gaharu is classified as one of the most valuable forest products traded internationally. Gaharu oil is widely use in religious ceremony, meditation, incense and perfume. Currently, local ent...
