The aim of study is to investigate the softening of cassava leaves during the fermentation of Ntoba mbodi and the mineral content of cassava leaves fermented and unfermented. The softening of cassava leaves is a characteristic of fermentation to produce Ntoba mbodi. It is due to an enzymatic process. The activity of cellulase and polygalacturonase enzymes, very weak at the beginning of fermentation, increases sharply in 24 h and decreases thereafter. The pectinesterase and pectin lyase activity, already present at the beginning of fermentation, reaches the maximum after 24 h of fermentation for pectinesterase and 48 h for pectin lyase. The cellulase is mainly of microbial origin. The cassava leaves softening is gradual and becomes maximum at the end of fermentation. It is accompanied by a loss of water leading to a decrease in protein and magnesium content. The Ntoba mbodi is richer in ash than fresh cassava leaves. Although Ntoba mbodi is a vegetable rich in minerals, its sodium content is low. Thus, Ntoba mbodi can be recommended for a meal without peril.
