Rice is one of the most common crops in the world, the staple food and the major energy source of people in East Asian countries. Rice consists mostly ofstarch, and therefore it is very prone to retrogradation after cooking.The term retrogradation is used to describe the changes that occurin gelatinized starch during storage, especially at low temperature.The components of rice starch, amylose and amylopectin, haveunique roles in the retrogradation of starch. Generally, amyloseis responsible for the short-term retrogradation, while the long-term retrogradation is ascribed to the reordering of amylopectin which is a much slower process involving mainly the recrystallization of the outer branched-chains of amylopectin. The retrogradation during production or storage profoundly affects quality, acceptability and shelf-life of starch or starch-containing foods
