yes, if it is dried and powdered it can be sustitute for a flour...
null hypothesis about banana flour?
I'd bet.
Not at all, in fact some people eat dried banana as a healthy snack.
You can use cake meal as a substitute for flour.
you could always experiment that is a whole category of cooking but I think it would be better to use dried fruit in banana bread like almonds or dried banana bits you can get that from a normal supermarket:)
tapioca
No it has the same amount of calories. By being dried, the banana is only losing water. Since water has no calories, the banana must be the same amount.
Self-rising Flour
i would thank so
Wholewheat flour
Substitute regular flour and baking powder (1 tsp per cup of flour) for self-raising flour. Add a bit of salt if you like, but not necessary.
