Processing Banana Into Flour

Banana fruit is a horticultural commodity that can be processed and preserved to expand its marketing value. Various processed banana products have already been developed, such as, sun-dried banana and banana crispy. A new product with a potential commercial value is the banana flour made from fresh and ripe banana.

Benefits

Banana flour can be used as a mixture material for various cakes/breads (wet and dry cakes), and for infant feeding. Banana flour contains low gluten, so it could not be used as the main cake material. Therefore, to produce high quality cake, banana flour must be mixed with wheat flour.
