It should be emphasized that the embodiments of the present invention are illustrative rather than restrictive, so the present invention includes but is not limited to the embodiments in the specific implementation manner. Other embodiments also belong to the protection scope of the present invention.

The degree of starch gelatinization in rice grains reflects the maturity of rice, which has a great impact on the quality and taste of the finished product, as well as whether it can meet commercial standards. The cooking time of the rice and the amount of water added have a big impact on the quality of the finished product. Each variety of rice has the best cooking time and water ratio. Increasing the water ratio is beneficial to improve the rate of cooked rice; shortening the cooking time will also affect the rate of cooked rice. However, the proportion of water added had no significant effect on the cooking time for fully cooked rice. Generally, pre-cooking, secondary cooking or multiple cooking are used to improve the gelatinization degree of rice starch. The key to improving the rehydration performance of rice is to improve the degree of gelatinization of rice grains. The higher the degree of gelatinization, the looser the structure, the better the porosity, and the faster the rehydration. The puffing process can also be used to expand the rice grains and present a porous structure inside, so that moisture can easily enter the inside of the rice grains. The rice can also be made into flakes or broken by means of extrusion, stamping, etc., to increase the surface area of rice grains, so as to improve the speed of rehydration.

The rice cooker mainly controls the hardness and taste of rice by controlling the degree of infiltration of water in the rice grains. In the current technology, the control of the electric rice cooker is relatively simple, and the existing electric rice cooker usually has two cooking methods, namely fine cooking and fast cooking. Fine cooking means higher requirements for the adjustment of firepower. When the fire is high, it will automatically switch to high fire, and low fire will switch to low fire, so the time is longer, while fast cooking refers to properly adjusting the firepower, shortening the water absorption and cooking time. , so the time will be shorter. The fine cooking and fast cooking of rice are basically fixed, or it is based on the decision of the computer. The ability to choose between fine cooking and fast cooking is not based on the taste of the eater, nor can it be customized and modified.
