Improvement in spray-drying technology for preparation of pregelatinized cassava starch Ciênc. Tecnol. Aliment.
SANTOS,Thais Paes Rodrigues dos; FRANCO,Célia Maria Landi; MISCHAN,Martha Maria; LEONEL,Magali.
Abstract Native cassava starch was gelatinized under different pretreatment conditions (preheating temperature, starch concentration and heating time) and spray-dried. A rotational compound central design was used to test the three independent variables: the preheating temperature, starch concentration, and heating time, and the behavior of the system was assessed by response surface methodology. The results showed a significant effect of both the preheating temperature and heating time on the cold viscosity. The combination of the preheating temperature and starch concentration affected the crystallinity, enthalpy change, solubility, and final viscosity. Modification by spray-drying resulted in a decrease in the crystalline regions, and enthalpy change,...
