α-Amylase: Both the drying and fermentation methods, and harvesting at unripe stage showed no significant effect (P>0.05) on α-amylase activity in papaya seed (Table 2). All the processing methods will not affect the rate of production of soluble sugars in the seed since α-amylase is responsible for breaking down of starch to simple sugars (Osuji, 1985). The low α-amylase activity reported in the papaya seeds is an indication of its low starch content. Thus, the processing methods (fermentation, and drying) will not affect the qualities (viscosity, and texture) of the final products obtained from the seed.
