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...
