Abstract

ABSTRACT The effect of glucose syrup addition on sour cassava starch fermentation was studied on cassava starch from three locations in Santa Catarina State (Brazil), following four treatments: traditional, 0.10, 0.25 and 0.50% of glucose syrup added to total cassava suspension volume. A glucose syrup concentration of 0.50% contributed to doubling fermentation yield. The objective of this work was to observe the effect of the cassava starch fermentation process on starch granule microstructure, as compared with industrial processing. Micrography was performed using a scanning electron microscope, at 2000× magnification. Fermentations with 0.50% glucose syrup presented the greatest effects on starch granule microstructure.
