Gewang (Corypha utan Lam.) as local food in timor island and its nutritional properties

Abstract

Gewang {Cory ph a utan Lam.] is a palm species which grows in the dry land and is distributed from North-east India to North Australia. Almost the whole part of that species has been utilized by Timor Island villagers for daily needs such as building construction, handicraft, animal fodder, alcohol beverages, sugar, and food. As food, gewang starch is extracted from its trunk. Before that starch is consumed, it is cooked with shredded coconut, named as"akarbilan" or "puta' laka". This food becomes common food, especially in isolated area in Tirnor Island. Based on our analyses, nutrient content of 100 gr gewang starch is as follow: 11.995 g water, 0.518 g ash, 0.202 g fat, 0.691 g protein, 86.594 g carbohydrate, 32.726 g amylose, 51.11 g amylopectin, 12.278 g glucomannan, 100.52 mg calcium (Ca), 136.74 mg phosphorus [P], 3.390 mg iron (Fe], 0.108 mg vitamin Bl. These results suggest those gewang starch nutrient contents are almost similar to sago starch, extracted from sago palm {Metroxylon sagu). In the future, investigation of gewang starch on their physical characteristics, non-nutritient properties, and processing should be carried out. Prospectively, gewang can to be used as food alternative, especially in dry land area such as Timor Island and adjacent regions in order to build food security in Indonesia.
