12.9 Summary and Future Research
Yam is one of the most highly valued crops in the world, with high potential for both household and industrial use. A lot of research work has been carried out on various yam processes and the results have proved to be successful. However, implementation of the successful research work on yam processing is expected to be done in the food industry, so as to improve its utilization as it has been done for other roots and tubers such as cassava and potato. Future research work on yam tuber may include processing yam into snacks such as yam crisps, biscuits, candies and canned products. These are convenience foods and could be easily accessible and available. To facilitate the production of these snacks, equipment and thorough process design must be put in place to achieve successful product development.
