Normal ripe bananas
Ethanol yields from the normal ripe fermentations
of the whole fruit, pulp and peel are shown in Table
4. The yields are shown per unit of fresh feedstock
and per unit of fresh whole fruit. The maximum
ethanol yield was obtained by fermenting the whole
banana. While the average ethanol yield for the pulp
was 0.116 I/kg of pulp, only 0.082 l/kg of whole bananas
was produced. This difference is because the
pulp is only 71% of the whole banana (Table 2).
