Acceptance of Aerial Yam (Dioscorea bulbifera L.) for Food in Biu Emirate Council, Borno State, Nigeria

Abstract

Aerial yam is a semi-wild food that grows on vines climbing onto poles and trees. The bulb is eaten on peeling off the hard back after cooking. Questionnaire was administered to investigate its acceptance for food in Biu environ as well as its taste. Proximate analysis was carried out to determine its nutritive value. About 85% of the respondents eat aerial yam as a supplement to their major food or meals. The result shows that elderly people of 36 years and above (58.83% of respondents) eat aerial yam being a common resource and cheap in the dry season. The taste varied with individuals as 58.82% stated that it is tasteless; 17.66%, bitter and 11.76%, indefinite. The samples analysed gave an average of 32% DM; 3.61%, CP; 3.06%, EE or fat; 8.65%, CF; 1.33%, ash and 83.56%, NFE. The integration of aerial yam in cropping system is therefore recommended as it has such a nutritional profile and ease of production.
