Sucrose hydrolysis in a glassy starch matrix

The purpose of present work was to investigate whether the glassy state may prevent sucrose inversion in an acid-containing amorphous starch powder (native or pre-gelatinized). It was found that sucrose hydrolysis occurred to a significant extent in the glassy state (in both native and gelatinized s...

Moisture content of the system affected the extent of sucrose hydrolysis but its effect was not attributable to the plasticizing effect of water.
