What are the various ways of preserving yam.?

Question

and also yam utilisation

Answer 1

Fresh yam tubers are lost after 4-5 months of storage. Drying of (injured) tubers soon after harvest and converting into slices or milling into flour for "fufu" ( pounded yam: peeled, boiled and pounded until a sticky elastic dough is produced ) ensures availability of yam in various forms. Traditionally processed yam products are made in most yam-growing areas, usually as a way of utilising tubers that are not fit for storage.

Another ( industrial )possibility is use of radiation for control of sprouting and improving the food qualities of stored yams.

The fungicidal  effect of an aqueous crude leaf extract and an extract of leaf phenolic acids of Acalypha hispida on biodeterioration of yam (Dioscorea rotundata) is analyzed:
