The project dealt on the production of yam flour from yam chips. The yams were
peeled and washed, 100grams samples coded sample A to G were subjected to
two different drying conditions. Some were dried using the sun drying method
while the others were dried through oven drying method kept at constant
temperature of 500C, sodium bi-carbonate was added to some of the samples, all
these were done to obtain a flour with the best colour and texture quality. From
the results obtained, it was observed that sample B (yam boiled with sodium bi-
carbonate and dried with oven) gave the best result and quality when tested with
hot water, this was as a result of the drying condition used, the constant
temperature maintained and the presence of the sodium bi-carbonate used which
helped in achieving the result. Generally, the samples dried through the oven
drying method at 500C gave better colour and result of the yam flour when tested
with hot water more than other samples dried by sun drying and this was due to
the stability in temperature in the oven drying method used.
