According to the cooking appliance of the embodiment, the low-sugar rice is produced by the following steps:

before cooking: the rice to be cooked is placed in the food steamer 300, the cooking water is respectively placed in the inner containers, the food steamer 300 is located at the bottom of the inner containers at the moment, and the water level of the inner containers at least submerges the upper surfaces of the rice in the food steamer 300.

And (3) low-temperature rotary water absorption stage: the water in the inner container is heated by small fire, the water temperature is kept at 40-50 ℃, and the sugar throwing device drives the steamer 300 to rotate at low speed for about 5 min. In the conventional low-sugar rice cooking, a low-temperature water absorption stage is not usually adopted, because the existing structure adopts excessive water washing or boiling with strong fire to overflow rice soup, and if the low-temperature water absorption stage is added, the rice is easy to soften and rot and has poor taste. In the embodiment, the sugar throwing device drives the steamer 300 to rotate at a low speed, so that a low-temperature water absorption stage can be increased, water can enter the center of rice grains, the phenomenon of uneven entrainment can be avoided, and starch can be dissolved in water; and the rotation of the water absorption stage and the steamer 300 can accelerate the water absorption of the rice grains, effectively shorten the water absorption time and improve the cooking efficiency.

A first sugar throwing stage: heating the water in the inner container with strong fire to keep the water temperature at 65-70 ℃, accelerating the rotating speed of the steamer 300 for 5-10 min, reducing the time for rice to stay at 40-60 ℃ as much as possible, avoiding that alpha-amylase is active and starch in the rice can decompose partial starch vigorously to generate reducing sugar under the action of the alpha-amylase; when the temperature reaches 60 ℃, water enters the interior of the rice grains through the starch cell gaps to hydrate with the amylose and the amylopectin, hydrogen bonds are broken, micelle areas are disintegrated, the starch is swelled and gelatinized, and the amylose is dissolved into water from the rice embryo milk tissue.

And a second sugar throwing stage: the water in the inner container is heated by big fire, the water temperature is kept at 75-85 ℃, the steamer 300 continues to rotate, and the duration time is 10-15 min. When the temperature is higher than 70 ℃, the amylopectin begins to be dissolved out of the rice endosperm, and part of the dissolved linear chains and amylopectin stays on the surface of the rice grains to form an adhesive layer of the rice and most of the dissolved linear chains and amylopectin are free in the rice soup. The starch content in the adhesive layer and the rice soup increases with the increase of cooking temperature, and when the temperature reaches 85 ℃, the starch dissolved out in the rice soup reaches the maximum value, and no solid matters are dissolved out from the tissues.

The steamer 300 is lifted and dried: the water in the inner container is heated to boiling by big fire, and the sugar throwing device drives the food steamer 300 to rotate and rise for about 5 min. Because the alpha-amylase is active at 80-90 ℃, the starch in the rice can decompose partial starch vigorously to generate reducing sugar under the action of the alpha-amylase, the starch in the rice soup can be gradually wrapped on the surface of the rice to form a water-retaining film, so the rice is quickly heated to boiling, the steamer 300 is rotated to rise when the water-retaining film is not formed and the content of the starch and the reducing sugar in the rice soup is the highest as far as possible, more amylose, amylopectin and broken starch grains free in the rice soup are retained in the inner container, and the excessive water on the surface of the rice grains is thrown away, so the rice is more uniform, and the taste of the rice is improved.

In the stage of slightly boiling rice steaming, the slightly boiling state of the water in the inner container is kept, and the rice in the steamer 300 is steamed by utilizing steam.

In the method for making the low-sugar rice, the steamer is driven to rotate by the sugar throwing device, rice and water in the steamer keep a tendency of moving towards the side wall of the steamer under the centrifugal action, but the water dropping holes limit the rice grains from passing through, so that the water can be thrown outwards, and the thrown water contains starch dissolved out from the rice grains, so the rice is called sugar throwing, so that the starch and reducing sugar in the rice are increased to be dissolved into rice soup, excessive water in the rice can be thrown away, the taste of the rice is effectively improved while the low sugar is realized, and the situations of dryness, dampness and instability are avoided.

As the present embodiment is preferable, the connecting rod 540 and the food steamer 300 are connected in a magnetic attraction manner, a snap connection manner, a threaded connection manner, etc. to realize a detachable connection, so that the food steamer 300 can be conveniently taken, placed and cleaned.

Preferably, the bottom wall of the inner container has a boss 210 protruding upward at the middle part, and the through hole 220 is provided at the top of the boss 210. The boss 210 is an internal hollow structure, part of the sugar throwing device can extend into the boss 210 for assembly, and the requirement for the height of a longitudinal space during the assembly of the sugar throwing device is reduced, for example, the guide sleeve 560 in the embodiment can be arranged inside the boss 210, the pressing plate 700 is arranged on the outer side of the boss 210, the guide sleeve 560 is connected with the pressing plate 700 through screws, the guide sleeve 560 is fixed, and the dynamic sealing ring 600 is also clamped and fixed up and down through the pressing plate 700 and the guide sleeve 560. The middle part of the bottom wall of the food steamer 300 is provided with the concave cavity 320 avoiding the boss 210, and the connecting rod 540 is connected in the concave cavity 320, so that the problem that the food steamer 300 cannot descend to the bottom of the inner container due to the interference of the boss 210 and the bottom wall of the food steamer 300 can be avoided.
