Indonesia oleoresin

In the gum rosin process, pine trees are wounded to stimulate the flow of gum. V-shaped slashes are cut through the bark, and the exudate is collected in a bucket below the slash. Production is stimulated by painting sulfuric acid on the slashes. The oleoresin (exudate) is separated by distillation into gum spidts of turpentine and gum rosin. The gum turpentine industry has decreased in importance in the 1990s because it is labor-intensive. The process is carried out in Russia, the People s Repubflc of China, Indonesia, Portugal, Brazil, and Mexico. 

The objective of this research was to characterize the essential oil and oleoresin composition of ginger rhizomes from Madagascar and to compare them with rhizomes coming from China, India and Indonesia. The work is part of a study conducted by the Centre de Recherche Cosmetique (CRC) of CHANEL to find new ginger varieties with unique characteristic for the cosmetic industry.
