BACKGROUND Rural households in the Mahafaly region of semi-arid SW-Madagascar strongly depend on the exploitation of natural resources for their basic needs and income regeneration. An overuse of such resources threatens the natural environment and people's livelihood. Our study focuses on the diversity and use of wild yams and medicinal plants. METHODS We hypothesized that knowledge on the u...

The present study seeks to evaluate the influence of the time of harvest on the phenolic composition, antioxidant activities and anti-cholinesterase action of processed yellow yam (Dioscorea cayenensis). HPLC-DAD analysis of the processed yellow yam revealed the presence of some phenolic acids and flavonoids. The result showed a higher amount of most of the identified phenolic compounds in the ...

Stakeholders operating within the yam export market lack shopper insights to formulate effective marketing and supply chain management strategies.

The physical and functional properties of trifoliate yam flours processed using different pre-treated methods at varying harvesting periods were examined. The flours were subjected to physical (bulk density) and functional (water absorption, solubility and swelling power) analyses. The bulk density values for the trifoliate flours ranged from 0.54-1.03 g/cm3. The parboiled flours had higher bul...
