Effects of drying temperature on the chemical and physical properties of Musa acuminata Colla (AAA Group) leaves.

Typically, banana trees are cut once the fruit has been harvested; however, other parts of the banana tree, particularly the leaves, might have other potential uses. Nevertheless, few studies have focused on banana leaves. This work aims to provide information about the effects of different drying t...
