Abstract
NUTRITIONAL COMPOSITION OF DIOSCOREA HISPIDA FROM DIFFERENT LOCATIONS AROUND LEUSER ECOSYSTEM AREA
Highlights
Dioscorea spp is an important source of carbohydrates in many tropical countries
This study reports the analysis results of proximate, mineral, phytochemical and cyanide content of D. hispida tubers collected from several area in the vicinity of the Leuser ecosystem in Aceh
The results showed that the nutritional content of D. hispida, mainly the high carbohydrate (58 - 72%), was comparable with other Dioscorea families
Summary
Dioscorea spp (generally called yam) is an important source of carbohydrates in many tropical countries. Efforts to domesticate wild yam have been made to utilize their phenotypic or genotypic superiority through crossbreeding with those that have already been cultivated [1]. Total carbohydrate content reaches 28%, which is higher than that in potatoes and sweet potatoes but lower than cassava. Four species of yam D. bulbifera, D. versicolor, D. deltoidea, and D. triphylla are reported to exhibit high antioxidant activities [7]. This study reports the analysis results of proximate, mineral, phytochemical and cyanide content of D. hispida tubers collected from several area in the vicinity of the Leuser ecosystem in Aceh. This plant is rarely cultivated, the results of this study may be used to increase the economic values of the plant. Utilization by communities around the Leuser ecosystem area may reduce forest infringement
