 Introduction  
Banana ( Musa spp ) is one of the important crops in  Africa. Bananas mainly fall in two categories; namely 
sweet banana and plantain. The former is normally consumed as dessert (sweet) banana, while the later are 
primarily consumed after cooking.  
Sweet banana can in addition used for preparation of desserts , purees and puddings; they can also be dried 
and eaten as a snack. Plantains can be dried and ground into flour.  
This standard provides guidance to processors and traders of dried banana in ensuring its quality and safety 
to consumers.
