Abstract:
Fluidized-bed agglomeration of native potato starch (NPS) with sugar binders [maltodextrin (MD) and lactose] produced larger particles with a more porous and diverse shape. Moreover, the agglomerated potato starch (APS) exhibited improved flowability and solubility. All powders displayed a B-type X-ray diffraction pattern. Although lactose did not impact the crystallinity of APS, that of APS prepared with MD decreased as the MD concentration increased. NPS showed higher gelatinization temperatures than APS prepared with distilled water (the control). Moreover, as binder concentration increased, the gelatinization temperatures and enthalpy of APS increased and decreased, respectively, indicating a delay in gelatinization. Similar results were observed with the pasting properties, wherein APS with sugar binders exhibited lower pasting, breakdown, setback, and final viscosities compared to the control. These were likely a result of decreased amylose leaching from the granules during heating due to the presence of sugar.

Physical Properties Affecting Solubility
As for any solution, the solubility of a gas in a liquid is affected by the attractive intermolecular forces between solute and solvent species. Unlike solid and liquid solutes, however, there is no solute-solute intermolecular attraction to overcome when a gaseous solute dissolves in a liquid solvent since the atoms or molecules comprising a gas are far separated and experience negligible interactions. Consequently, solute-solvent interactions are the sole...
