The low-sugar rice cooker is a patented siphon sugar removal technology, in which rice is boiled with water. When the water temperature rises above 53℃, the starch will gelatinize. A part of the starch diffused into the water is left in the rice soup by separating the rice soup, so that the remaining rice sugar will be reduced a lot. After that, continue to steam the rice, and the sugar-free rice will be completed.
