The data on the sensory scores of the finished products are listed in Table 5. It can be seen that color, appearance and crispiness of the two types of snacks degraded significantly with increase in the green banana flour (GBF) substation level while the oiliness improved gradually. This is in agreement with previous results of he analysis of texture and color as well as oil content. Except fora bitter taste in the cassava cracker (CC) replaced 50 g by GBF from 100 g cassava starch, aftertaste in the other products was charac-terized by a sweet taste and banana flavor, all of which became increasingly evident with increased content of GBF. Considering overall acceptability there were no significant differences among the products with not more than 40 g substitution level by GBF from 100 g cassava starch in CC and not more than 15 g in FC. So the highest substitution level is considered as 40 g by GBF from 100 g cassava starch in CC and 15 g by GBF from 100 g cassava starch in FC,respectively.
