Histological description of fresh, cooked and frozen cassava flesh

The aim of this study was to describe the histological feature of cassava flesh at harvest, after cooking and after freezing. A light optical microscopy was used to analyze the relevant aspects of cassava flesh at these statuses. The non-uniform aspect of cooked cassava is associated with the partial dissolution of the middle lamella and the large amount of non-collapsed cells, while the formation of numerous spaces between cells determines the spongy aspect of cassava after freezing. These data increase the knowledge about cassava post harvest and its processing.
