Studies were conducted to determine the most suitable conditions for the lye-peeling of fresh yam, Dioscorea alata, of the Florido variety. Good peeling resulted from each of these boiling lye solution combinations: 5 minutes in 10-percent, 4 minutes in 15-percent, or 3 minutes in 20-percent. The average weight loss resulting from these three combinations was approximately the same, but less in each instance than when the tubers were hand-peeled. Changes in titrable acidity and hardness values of the tubers were approximately equal to those which resulted from hand-peeled yam. The sensory evaluation of the samples showed no significant difference between hand- and lye-peeled tubers. The lye-peeling method was not wholly satisfactory when the yams had been in storage for more than 3 weeks.
