Raw cassava starch was treated with α-amylase and amyloglucosidase in aqueous solution under annealing condition to obtain starch granules with rough and porous surfaces. Many different pits and pores formed by the activity of the enzymes on the surface granules and were observed by scanning electron microscopy (SEM). The obtained starch granules with rough surfaces were mechanically blended with poly(butylenes adipate-co-terephthalate)(PBAT) at different ratios by using a single screw extruder. The results showed that the samples comprised of enzymatically treated starch blends had higher elongation than those comprised of untreated starch blends. At 10% starch content, the treated starch/PBAT blend had about 37.55% more elongation than the untreated starch/PBAT blend. This resulted in the improved compatibility of the starch granules and PBAT matrix in the blends as confirmed by SEM.

ABSTRACT: Sour cassava starch is a naturally modified starch produced by fermentation and sun drying, achieving the property of expansion upon baking. Sour cassava starch' bakery products can be prepared without the addition of yeast and it is gluten free. The fermentation process associated with this product has been well studied, but the wastewater, with high acidity and richness in other organic compounds derived from starch degradation, requires further investigation. In this study, the structure of solids present in this residue was studied, seeking to future applications for new materials. The solids of the wastewater were spray dried with maltodextrin (MD) with dextrose equivalent (DE) of 5 and 15 and the structure of the powder was evaluated by scanning electron microscopy. A regular structure with a network arrangement was observed for the dried material with MD of 5 DE, in contrast to the original and fermented starches structure, which suggests a regular organization of this new material, to be studied in future applications.
