Gelatinized, amorphous starch molecules tend to recrystallize in a double helical structure
during storage, which is also known as starch retrogradation. The rate of starch
retrogradation depends on the amylose content, the amylopectin structure, the lipid content,
the storage temperature, and the moisture content of starch paste. Amylose retrogrades faster
8
than amylopectin because of the linear structure and the high mobility of the amylose
molecules (Sievert and Wusch 1993).
