Abstract: The effect of sprouting on the cookability of cocoyam tubers
was investigated. Cultivars of Xanthosoma sagittifolium and Colocasia
esculenta were planted. The planted tubers were unearthed after every 2
days and their cooking time determined until complete sprouting was observed.
The planted cocoyam tubers were also dried and ground into cocoyam flour after
being unearthed every other day. The water absorbtion, oil absorbtion and gelation
temperature of these cocoyam flour samples were also determined. The cooking
time for all cultivars increased with increase in the days of sprouting. It
was observed that all the cocoyam cultivars could no longer cook after full
sprouting was observed which occurred within 8-12 days from the day of planting.
Physicochemical properties of the cocoyam flour as affected by days of sprouting
also showed that gelation temperature increased while water and oil absorption
decreased with increase in the days of sprouting.
