ABSTRACT

Four common Dioscorea species were analyzed for dietary fibre components viz, hemicellulose, cellulose and lignin as well as Neutral Detergent Fibre (NDF) and Acid Detergent Fibre (ADF) in the raw and cooked samples. The dietary fibre components in the raw and cooked samples in all the four yam species namely Disocorea bulbifera, Dioscorea alata, Dioscorea cayenenis and Dioscorea rotundata were found to be low ranging from 1.20-2.59% for NDF, 1.06-2.22% for ADF, 0.10-0.27% for hemicellulose, 0.07-1.13% for cellulose and 0.08-0.27% for lignin. There was no significant change (p<0.05) in the content of dietary fibre components of the yam samples upon cooking. In spite of the low levels of fibre in the yam species analyzed, yams may constitute a significant source of fibre for many in Nigeria and the tropics generally since they are a common staple and are widely consumed on a daily basis.
