Comparison of Traditional Storage Methods of Sheanut Kernels (Vitellaria paradoxa Gaertn.) Using Drying Curves
Résumé
Water content of a product depends on many parameters amongst which are temperature and relative humidity of its environment. A study was carried out on the dehydration of sheanut kernels (Vitellaria paradoxa Gaertn.) in order to compare three traditional storage methods and identify the better one for their preservation as a function of time. Sheanuts stored under different conditions (atmospheric, under ground in a polyvinyl bag and under the sand) underwent drying in a forced convection dryer. The results obtained showed that before 7 h of drying, samples stored under the sand had a better coherence while after this time better results were obtained with samples stored under the ground in a bag. These results indicate that the traditional under ground storage of sheanuts by female farmers at the village level should be enhanced.
