Abstract
This review paper discusses the physicochemical characteristics of three different species of Palmae (Arenga pinnata, Cocos nucifera, dan Nypa fruticans) as alternative materials to produce galactomannans. Galactomannan has generally been widely applied and used in the food, pharmaceutical, cosmetic and paper industries. The major galactomannans of commercial importance in industries (guar gum, tara gum and locust bean gum) are limited in Indonesia. Therefore important to search for alternative renewable sources. The galactomannans were obtained by aqueous extraction followed by a precipitation with ethanol. The yield, monosaccharide composition and physicochemical parameters of the extracted galactomannans are different. The results confirm the possibility to produce galactomannan from various palms.
