When the food is left over, it will be eaten again, or the leftovers will be fried and eaten. Many people think that this is both hygienic and economical. In fact, it is difficult to digest the food left over after it is reheated. Over time, it may cause stomach problems. Let's take a look at how the starch, the main ingredient in rice, is digested and absorbed in the body. First, saliva amylase in the oral cavity hydrolyzes starch to dextrin and maltose. Second, amylase and diacylase secreted by the pancreas in the small intestine continue to degrade dextrin and maltose into monosaccharides for absorption by intestinal mucosal cells. When starch is heated above 60°C, it will gradually expand and eventually become a paste. This process is called "gelatinization." Digestive enzymes in the human body are more likely to hydrolyze this gelatinized starch molecular structure. However, after the gelatinized starch is cooled, the molecules in the starch are rearranged and excreted water, resulting in a phenomenon called "dissolving," which is called "aging" of the starch. Even if the reheated starch molecules are reheated, even if the temperature is high, the molecular structure at the time of gelatinization cannot be restored. The aging state of starch reduces the body's ability to hydrolyze and digest it. Therefore, long-term consumption of such cold and hot meals, prone to indigestion and stomach problems. Therefore, it is best not to eat or eat rice that has been reheated after being chilled if the digestive function is weakened by the elderly, infants or patients, especially people with gastrointestinal problems.
