As shown in FIGS. 11-23 , the control method for a cooking appliance according to an embodiment of the present application includes the following steps:

After receiving the cooking instruction, controlling the cooking appliance to heat to at least partially gelatinize the food;

The cooling device is controlled to deliver a cooling medium into the cooking container to cool the food.

As shown in FIG. 11 , in some embodiments, after the cooking utensil is heated until the surface of the food is gelatinized to form a gelatinized layer, the cooling device is controlled to deliver a cold medium into the cooking container, so that the gelatinized layer is cooled to form resistant starch crystals layer.

The following is an example of using rice as the food material and water as the liquid. The inventor of the present application has found through long-term research that raw rice itself contains a high amount of resistant starch, and the higher the water content of the rice, the easier it is to promote the conversion of resistant starch into digested starch. The rice is first heated until it is half-cooked and half-cooked. At this time, the surface of the rice is gelatinized to form a gelatinized layer, and then the cooling device is controlled to cool the rice grains to form a layer of resistant starch crystals on the surface of the rice. The starch crystalline layer can block the conduction/transmission of water and heat, thus preventing the conversion of resistant starch inside the rice and achieving a low sugar effect.

As shown in FIG. 12 , in some examples, after the cooling device is controlled to deliver the cold medium into the cooking container, the cooking appliance is controlled to continue heating to increase the temperature of the food. That is, after the ingredients are partially gelatinized, a cold medium is introduced to cool the gelatinized layer to form a resistant starch crystalline layer, and then heating is continued to fully ripen the ingredients.

For example, when the cooking utensil is working, add the rice into the cooking container, first dry/bake/bake at 100°C for 6 minutes (ie, anhydrous state), so that the surface of the rice is gelatinized to form a gelatinized layer, and then controlled The cooling device delivers a cold medium into the cooking container, for example, adding cooling liquid to the cooking container, so that the gelatinized layer on the surface of the rice is cooled and regenerated to form a resistant starch crystalline layer, and finally the cooking utensils are controlled to continue heating to achieve heating and cooking. During the cooking process, the resistant starch crystalline layer wraps the inner starch of the rice to control the water absorption of the rice and reduce the loss of resistant starch during the cooking process.

As shown in FIG. 13 , in other examples, the cooling medium is cooling liquid, and after the cooling device is controlled to deliver the cooling liquid into the cooking container and soak the ingredients for a preset time, the cooking appliance is controlled to discharge the liquid.

In other examples, controlling the cooking appliance to heat to at least partially gelatinize the ingredients includes: controlling the cooking appliance to dry-fire the ingredients in the cooking container to gelatinize the surface of the ingredients to form a gelatinized layer.

For example, when the cooking utensil cooks rice, since the rice grains themselves contain a certain amount of water, by dry burning the rice grains, the moisture inside the rice grains evaporates, so that a gelatinized layer is formed on the surface of the rice grains. The cold medium can cool and regenerate the gelatinized layer on the surface of the rice grain to form a resistant starch crystalline layer. The resistant starch crystalline layer wraps the starch inside the rice grain, controls water absorption, and reduces the loss of resistant starch during cooking.
