The RSW is related to the amount of soluble solids in a dry sample, allowing verifying the degree of the severity in the treatment, as a function of the degradation, gelatinization, dextrinization
and consequent solubilization of the starch (CARVALHO et al.
Thermoplastic extrusion can promote starch dextrinization
, resulting in the formation of low molecular weight compounds, such as sugars, emphasizing maltose.
Derived from vegetal sources, traditional dextrinization
is used to obtain NUTRIOSE FB and NUTRIOSE FM from wheat starch and non-GMO corn starch, respectively.
Furthermore, it was found that the maximum required torque for the mixing in the gelatinization process was 11 N*cm and 1 N*cm for the dextrinization
24) at very high temperatures, the molten mass of material is not able to retain the vapor generated when exiting the die, due to starch dextrinization
and the weakening of the structure.
can be accomplished using either a mineral acid or an organic acid as a catalyst.
