Detailed ways

The embodiments of the present disclosure are described in detail below. Examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the drawings are exemplary, and are intended to explain the present disclosure, but should not be construed as limiting the present disclosure.

With the continuous development of China's economy and the increasing living standards of the people, the national dietary health problems have become increasingly prominent. Chronic diseases such as high blood pressure and diabetes caused by improper diet have attracted great attention from consumers and the society. According to authoritative data from the World Health Organization, there are approximately 370 million diabetic patients in the world, of which 114 million are Chinese diabetic patients, ranking first in the world, and potential diabetic patients may be as high as 500 million. Faced with the turbulent situation of diabetes, experts at home and abroad call for the need for prevention and treatment, but prevention must be the leading factor, and dietary prevention is the top priority.

Recent studies have shown that daily diet is the most basic way to control high blood sugar, among which staple food is an important part of daily diet. Starting from the staple food, helping to solve the health problems of people with high blood sugar is the most basic and effective method. Rice cookers and electric pressure cookers play an important role as important appliances for cooking staple foods. If the problem of staple food sugar control can be solved, the problem of staple food restriction in people with high blood sugar can be solved, and the risk of hyperglycemia can be alleviated. Although it is not a substitute for drug treatment after illness, it has a positive effect on preventing the occurrence of hyperglycemia and even diabetes.

Based on this, the present disclosure proposes a cooking appliance and a control method and device thereof to increase the content of resistant starch in rice, change the digestibility of starch in the rice, delay the digestion speed of the rice, and thereby reduce the sugar increase of the rice.

According to research, although rice contains more than 90% of the nutrients needed by the human body and can provide comprehensive nutrition for the human body, its starch content is as high as 70%-80%. After the human body digests and absorbs the starch, it will gradually decompose into glucose. It enters the bloodstream, causing blood sugar to rise. Especially for people such as fitness, beauty, and high blood sugar, especially in communities that care about sugar, rice has a certain risk of raising sugar.

Starch is divided into fast digestion starch, slow digestion starch and resistant starch in terms of digestion characteristics. Among them, resistant starch also becomes indigestible starch, which is not absorbed in the small intestine and does not cause blood sugar to increase. It has the effects of stabilizing blood sugar, reducing hunger, laxative, and weight loss. Therefore, increasing the content of resistant starch is an effective means to improve the sugar control effect of rice.

There is a certain amount of resistant starch in raw rice. It is mainly starch that has a dense structure and a partial crystalline structure that cannot be acted on by amylase. During the cooking and gelatinization of rice, the starch crystalline structure is destroyed. The resistance to enzymatic hydrolysis gradually decreases, and the content of resistant starch also gradually decreases. Therefore, by controlling the degree of gelatinization, moisture, and the degree of binding of starch and protein fat, etc., the rice can retain a higher content of resistant starch after cooking.

Furthermore, when starch is heated under sufficient water conditions, a large amount of water will enter the starch granules, causing intermolecular hydrogen bonds to be destroyed, and water molecules begin to connect to the exposed hydroxyl groups of amylose and amylopectin through hydrogen bonds. On the base, the swelling and dissolution of the particles are caused, and the resistant starch is reduced. Studies have found that the relationship between rice-water contact time and resistant starch content when the water temperature is greater than or equal to 95°C is that the shorter the rice-water contact time, the higher the resistant starch content. The specific data are as follows:

Table 1

Water temperature ≥95℃ rice water contact time	Resistant starch content
Existing technology: 20-25min	≤8%
15min	9%-10%
10min	11%-12%
5min	15%-16%

It should be noted that the content of resistant starch is related to the water absorption rate. Therefore, the water absorption rate of rice can be tested to detect the content of resistant starch. Specifically, the relationship between the resistant starch content and water absorption rate is as follows:

Table 2:

Water absorption	Resistant starch content
10%	16%-17%
15%	13%-15%
20%	10%-11%
30%	9%-10%
40%	8%-9%

Therefore, the water absorption time and water absorption of rice grains are important factors that determine the final resistant starch content of rice. Among them, the water absorption may include the soaking and water absorption stage before the rice grains gelatinize, and also include the rice heating, boiling, and braising stages, that is, the total time that all rice water contacts during the cooking process and the rice grains can absorb water. The present disclosure is a control scheme for the rice water contact time in the soaking water absorption stage and the boiling and braising stage.

The cooking appliance and its control method and device according to the embodiments of the present disclosure will be described below with reference to the accompanying drawings.

The cooking appliance may be an electric rice cooker, an electric pressure cooker, an electric cooker, an induction cooker, or a health pot. For example, the present disclosure takes the cooking appliance as an electric rice cooker as an example, but this is not a limitation of the protection scope of the present disclosure. After reading the specification of the present disclosure, a person of ordinary skill in the art can obviously apply the cooking appliance of the present disclosure to electric pressure cookers, electric cookers, induction cookers, or health pots, etc., after knowing the technical concept of the present disclosure.

Fig. 1 is a flowchart of a control method of a cooking appliance according to a first embodiment of the present disclosure. As shown in FIG. 1, the method for controlling a cooking appliance according to an embodiment of the present disclosure includes the following steps:

S101: Identify that the water temperature in the cooking appliance is in a preset cooking temperature range.

Wherein, a temperature sensor may be provided in the main body to detect the water temperature in the main body in real time during the cooking process, and to identify the detected water temperature to determine that the water temperature is within the preset cooking temperature range.

Specifically, by detecting and identifying that the water temperature is less than or equal to the first preset temperature, it is determined that the cooking appliance is in the first preset temperature range, and the food and water in the cooking appliance are controlled to be in contact with the water for the first preset time; or detecting and identifying that the water temperature is greater than or When the temperature is equal to the second preset temperature, it is determined that the cooking appliance is in the second preset temperature range, and the food and water in the cooking appliance are controlled to be in contact with the water for the second preset time.

It should be noted that, in the embodiment of the present disclosure, the first preset temperature may be 65°C, the first preset time may be 5-10 minutes, the second preset temperature may be 95°C, and the second preset time may be It is 5-15 minutes, that is to say, control the contact between ingredients and water for 5-10 minutes in the soaking and water absorption stage of cooking, and the total time of contact between ingredients and water in the boiling and braising stage is 5-15 minutes.

S102: According to the preset cooking temperature range, control the contact of the food material and the water in the cooking appliance for a preset time.

Further, during the cooking process, in addition to the contact time, the food and water in the cooking appliance are controlled to be in a separated state.

Wherein, as shown in FIG. 3, a cooking appliance according to a specific embodiment of the present disclosure includes a main body part and a food material holding part. The main body part has an accommodating cavity, and the food material holding part can be placed in the accommodating cavity. In the cooking state, water is contained in the main body and rice is contained in the food material holding part. During the cooking process, the water in the main body is heated to realize the cooking of steaming the rice in the food material holding part.

That is to say, during the cooking process, the temperature of the water in the main body is recognized first, and if it is recognized that the current water temperature is in the first preset temperature range or the second preset temperature range, then the food and water in the food holding portion are further controlled. The contact time is kept within the preset time, and the food and water are controlled to be kept separate at the time except the contact time.

According to an embodiment of the present disclosure, as shown in FIG. 2, during the cooking process, in addition to contacting the four pieces, controlling the food and water in the cooking appliance to be in a separated state also includes:

S201: Control the food and water in the cooking appliance to keep in contact for a preset time.

S202: Control the separation of food and water in the cooking appliance.

That is to say, in the cooking process, you can first control the continuous contact between the food in the food holding part and the water in the main body, and then control the separation of the food and water when the contact between the food and water reaches the preset time. The food and water are only in contact for a preset time, thereby increasing the content of resistant starch in the rice.

According to another embodiment of the present disclosure, during the cooking process, in addition to the contact time, controlling the food and water in the cooking appliance to be in a separated state, and also includes: alternately controlling the food and water in the cooking appliance to be in a contact state and a separated state.

In other words, it is also possible to alternately control the state of the food and water, that is, the food and water are in contact and the food and water are in a separate state, the two states alternately, and the time for controlling the food and water to be in contact is less than or Equal to the preset duration, thereby increasing the content of resistant starch in the rice.

For example, in the initial stage of cooking, when it is detected that the water temperature in the main body is less than or equal to 65°C, the food in the food holding section can be controlled to keep in contact with the water in the main body for 5-10 minutes, and then the food and water can be controlled to separate, or Control the food and water to maintain a separate state until the water temperature is about 5-10 minutes before the temperature is heated to 65 ℃ to control the contact between the food and the water, or control the alternate state of contact between the food and the water-separated state-contact state-separated state, And detect the cumulative time of the contact between the food and the water, and control the food and the water to maintain a separate state when the cumulative time reaches 5-10 minutes.

In the later stage of cooking, when it is detected that the water temperature in the main body is greater than or equal to 95°C, the food in the food container can be controlled to keep in contact with the water in the main body for 5-15 minutes, and then the food and water can be controlled to separate, or the food and water can be controlled. The contact state-separation state-contact state-separation state alternately changes, and the cumulative time of contact between food and water is detected, and when the cumulative time reaches 5-15 minutes, the food and water are controlled to remain separated. It should be understood that the boiling stage and the steaming stage are implemented in the later cooking stage. Since the boiling stage needs to be preceded by the steaming stage, only the boiling stage (the ingredients and water are in contact) has priority over the steaming stage (the ingredients and water). In a separated state), or control the boiling stage and the steaming stage alternately. In short, the steaming stage cannot be completely prior to the boiling stage, that is, in the second preset temperature range, the food and water cannot be controlled to separate until the final stage before contacting. .

Further, the cooking appliance includes a main body part and a food material holding part. The main body part has an accommodating cavity. The food material holding part can be placed in the accommodating cavity to control the contact between the food and water in the cooking appliance. It also includes: controlling the lowering of the food material holding part. The water entering the containing cavity and/or controlling the rise of the water in the containing cavity so that the food is immersed in the water.

Among them, water flow holes are arranged on the food holding part.

That is to say, a transmission mechanism may be provided in the main body of the cooking appliance, and the food holding part can move up and down in the accommodating cavity through the transmission mechanism, so as to control the food holding part to descend and enter when the food in the cooking appliance is in contact with water. In the water in the accommodating cavity, it should be understood that the main body can also be controlled to move upward according to the principle of relative movement, so that the water in the accommodating cavity rises and the food is immersed in the water. In contrast, when controlling the separation of the food and water in the cooking appliance, the food holding part can be controlled to move up or the body part to move down, so that the water in the accommodating cavity flows out through the water flow holes to realize the separation of rice and water.

Furthermore, since the water temperature in the second preset temperature range is relatively high, continued heating is likely to produce a change in the form of water (liquid water vaporizes into water vapor). At this time, a water vapor pressure cavity is easily formed between the food holding portion and the accommodating cavity. The vapor pressure gradually increases, and the water at the bottom of the accommodating cavity is squeezed to gradually increase the water level around the accommodating cavity until it rises to the point that it enters the food containing portion through the water flow holes arranged around the food containing portion to achieve rice water contact.

Furthermore, when the method is used to realize the contact between the food and the water, the switching between the contact state and the separation state of the food and the water can be realized by adjusting the power regulation ratio of the heating part. In other words, when the food and water need to be in contact, the power adjustment ratio is controlled to increase to increase the water vapor content by heating the water in the accommodating cavity to achieve contact between the food and water, and separate the food and water when necessary When the power adjustment ratio is reduced, the water vapor is reduced by stopping the heating of the water in the accommodating cavity, and the food material and the water are separated.

Thus, according to the control method of the cooking appliance according to the embodiment of the present disclosure, it is possible to realize the control of the contact time between the food and the water by identifying the water temperature in the cooking appliance, effectively increase the content of resistant starch in the rice, and change the starch in the rice. The digestive properties of rice can delay the digestion speed of rice, thereby reducing the sugar increase of rice.

Fig. 4 is a flowchart of a control method of a cooking appliance according to a second embodiment of the present disclosure. As shown in Figure 1, the control method of the cooking appliance includes the following steps:

S401: During the cooking process of the cooking appliance, determine the current cooking stage of the cooking appliance, where the cooking stage of the cooking appliance includes a boiling stage.

It is understandable that the cooking stage of the cooking appliance may include a heating stage, a boiling stage, and a rice braising stage. Taking the cooking appliance as an electric rice cooker as an example, in the heating stage, the bottom heating module in the electric rice cooker can heat the inner pot until it reaches the inside of the pot. Boiling occurs, for example, when the temperature in the pot reaches a first temperature value such as 95°C to 100°C, it is judged that boiling occurs in the pot. At this time, the boiling stage is entered, and the boiling in the pot is maintained, for example, the temperature in the pot is maintained at the first temperature. When the duration of the boiling phase reaches the preset boiling time or the bottom temperature of the pot reaches the third temperature value, the rice stew phase is entered. During the braising stage, the heating is stopped, and after the heating is stopped for a preset supplementary cooking time, the bottom heating module in the rice cooker is controlled to reheat for the preset time.

S402: When the cooking appliance is in the boiling stage, obtain at least two power regulation ratios, and control the cooking appliance to alternately heat according to the at least two power regulation ratios, so as to make the cooking appliance intermittently boil.

It should be noted that the power regulation ratio can refer to the ratio of heating time to stop time. For example, the total time of each cycle (the sum of heating time and stop time) is 16 seconds, then 4/12 means heating for 4 seconds , Stop for 12 seconds.

It should also be noted that the intermittent boiling in the cooking appliance may refer to at least one boiling state and at least one stop boiling state in the cooking appliance during the entire boiling stage.

Therefore, in the embodiment of the present disclosure, during the boiling phase, by controlling the power adjustment ratio of the cooking appliance, such as the bottom heating module, the intermittent boiling in the boiling phase is realized, so that the boiling is discontinuous, and the gelatinization degree of the rice is controlled to prevent long-term boiling. This leads to the problem of high gelatinization of rice but low content of resistant starch, thereby increasing the content of resistant starch in the rice, controlling the fluctuation of blood sugar after the rice meal in the human body, and maintaining the relative stability of blood sugar in the human body.

It should be understood that controlling the cooking appliance to alternately heat according to at least two power adjustment ratios includes: controlling the cooking appliance to perform heating by using at least one of the at least two power adjustment ratios to make the cooking appliance in a boiling state. At least one of the power regulation ratios controls the cooking appliance to perform heating work, so that the cooking appliance stops boiling. In other words, at least one of the at least two power regulation ratios makes the cooking appliance boil, and at least one of the at least two power regulation ratios causes the cooking appliance to stop boiling.

Specifically, the at least two power regulation ratios may include a first power regulation ratio and a second power regulation ratio, where controlling the cooking appliance to alternately heat according to the at least two power regulation ratios includes:

Controlling the cooking appliance to perform heating work with the first power regulation ratio so that the cooking appliance is in a boiling state, wherein the total time of heating work with the first power regulation ratio reaches the first time threshold;

The cooking appliance is controlled to perform heating work at the second power regulation ratio to stop boiling in the cooking appliance, wherein the total time for the heating work at the second power regulation ratio reaches the second time threshold value.

It should be noted that the first time threshold refers to the total time that the cooking control is performed at the first power regulation ratio, and the second time threshold refers to the total time that the cooking control is performed at the second power regulation ratio, in other words, the first time The threshold may refer to the total duration of the boiling state, and the second time threshold may refer to the total duration of stopping the boiling state.

That is to say, the intermittent boiling in the cooking appliance can be controlled by alternately heating the cooking appliance with the first power regulation ratio and the second power regulation ratio. In the embodiments of the present disclosure, the first power regulation ratio and the second power regulation ratio are not limited. For the alternate heating method of ratio, as long as it is ensured that the boiling phase occurs once for heating with the first power regulation ratio and once for the heating with the second power regulation ratio.

For example, the cooking appliance can be controlled to perform heating at the first power regulation ratio first, and the cooking appliance is in a boiling state at this time, and after the first time threshold is used for heating at the first power regulation ratio, the cooking appliance is controlled at the second power regulation ratio. The cooking appliance performs heating work. At this time, the cooking appliance stops boiling and maintains the second time threshold. For another example, the cooking appliance can be controlled at the first power regulation ratio to perform heating work. At this time, the cooking appliance is in a boiling state, and after heating at the first power regulation ratio for t1 time, the cooking appliance can be controlled at the second power regulation ratio. The cooking appliance is heating. At this time, the cooking appliance stops boiling and performs heating at the second power regulation ratio. After the second time threshold, the cooking appliance is again controlled at the first power regulation ratio to perform heating. At this time, the cooking appliance is in It is in a boiling state, and the heating operation is continued at the first power adjustment ratio for a time t2, where the sum of the time t1 and the time t2 is the first time threshold.

It should be understood that the first time threshold and the second time threshold, the first power regulation ratio and the second power regulation ratio can be set reasonably according to the required resistant starch content. For example, the first power regulation ratio can be 10/6, the first time threshold can be 1.5 minutes, the second power regulation ratio can be 4/12, and the second time threshold can be 8.5 minutes, that is, the cooking appliance can enter the boiling stage Then, the heating module is controlled to work for 1.5 minutes at a power regulation ratio of 10/6, that is, heating for 10 seconds, and then stop for 6 seconds. At this time, the cooking appliance is boiling, and then heating at a power regulation ratio of 4/12, that is, heating for 4 seconds and stop The heating module is controlled to work for 8.5 minutes in seconds. At this time, the cooking appliance stops boiling.

The first time threshold may be less than the second time threshold, the value range of the at least two power adjustment ratios may be 1/15-7/1, and the duration of the boiling phase may be less than 30 minutes.

According to a specific example, as shown in Table 3 below, four implementations of the first time threshold and the second time threshold, the first power regulation ratio and the second power regulation ratio and the second power regulation ratio are given. The resistant starch content of the rice in each embodiment is shown.

table 3

It can be seen that by adjusting the first time threshold and the second time threshold, the first power regulation ratio and the second power regulation ratio, the content of resistant starch in the rice after cooking can be controlled, for example, When the first power regulation ratio is 10/6, the first time threshold is 1.5 seconds, the second power regulation ratio is 4/12, and the second time threshold is 8.5 seconds, the resistant starch content after cooking is 9.86%; When the first power regulation ratio is 8/8, the first time threshold is 1.5 seconds, the second power regulation ratio is 4/12, and the second time threshold is 8.5 seconds, the resistant starch content after cooking is 12.13%; When the first power regulation ratio is 6/10, the first time threshold is 1.5 seconds, the second power regulation ratio is 3/13, and the second time threshold is 9.5 seconds, the resistant starch content after cooking is 11.45%; When the first power regulation ratio is 4/12, the first time threshold is 2 seconds, the second power regulation ratio is 2/16, and the second time threshold is 11 seconds, the resistant starch content after cooking is 10.11%.

In addition, it should be noted that the at least two power regulation ratios are not limited to the first power regulation ratio and the second power regulation ratio, and may also include a third power regulation ratio, which may be a power regulation capable of boiling in the cooking appliance. The power ratio can also be a power control ratio that can stop boiling in the cooking appliance, and the alternate mode of the first power control ratio, the second power control ratio, and the third power control ratio is not limited in the embodiment of the present disclosure, as long as it is in the boiling stage. It is sufficient to control the cooking appliance at least once with the first power regulation ratio to perform heating work, at least once at the second power regulation ratio to control the cooking appliance for heating work, and at least once at the third power regulation ratio to control the cooking appliance to perform the heating work.

For example, the control method of the cooking appliance of the embodiment of the present disclosure can be used in a rice cooker with a conventional structure. In the boiling phase, the rice cooker is heated at the first power adjustment ratio for the first time threshold. At this time, the rice cooker boils to accelerate the gelatinization of rice, and then The rice cooker heats the second time threshold at the second power regulation ratio. At this time, the rice cooker stops boiling and reduces the degree of gelatinization of the rice. Thus, by adjusting the first time threshold and the second time threshold, the first power regulation ratio and the second The power adjustment ratio achieves different degrees of discontinuous boiling, which can control the degree of gelatinization of the rice and increase the resistant starch content in the rice after cooking.

In addition, it should be noted that the cooking appliance control method of the embodiment of the present disclosure may also be used in the following rice cookers. For example, the rice cooker may include: a main body, a holding part, and a medium replacement part. The holding part is used for holding rice. The body part has a cooking cavity, wherein the cooking cavity may be a cavity defined by the pot body part and the upper cover part of the body part. The containing part is arranged in the cooking cavity. The medium replacement part is arranged in the cooking cavity, and the medium replacement part is used for realizing the replacement of the first medium and the second medium, thereby changing the liquid level in the cooking cavity.

For example, the medium replacement part is configured to replace the liquid second medium in the medium replacement part with the first medium, so that the replaced second medium can exit the medium replacement part and flow the second medium into the cooking cavity, so that the cooking cavity can be changed. Level inside. For another example, the medium replacement part is also configured to use the second medium outside the medium replacement part and in a liquid state to enter the medium replacement part to occupy at least a part of the space occupied by the first medium, thereby reducing the liquid level in the cooking cavity When the liquid level drops, the liquid will wash away the rice and reduce the sugar in the rice. In other words, the liquid second medium can enter the medium replacement part to occupy at least a part of the space previously occupied by the first medium. For example, when the cooking appliance stops heating or the heating power is reduced, the first medium, such as water vapor, in the medium replacement part is liquefied , The liquid second medium outside the medium replacement part, such as water, will enter the medium replacement part, replacing the space previously occupied by the first medium.

Moreover, the containing portion can be in communication with the cooking cavity, and after the second medium flows into the cooking cavity, the liquid level in the containing portion can be changed. It should be noted that the first medium may be water vapor, and the second medium may be water.

Specifically, the specific working process of the rice cooker is as follows: during the cooking process of the rice cooker, first pour an appropriate amount of clean water into the cooking cavity, and then put the holding part and the medium replacement part into the cooking cavity, so that the water level in the cooking cavity is roughly under The medium replacement part (of course, it can be appropriately higher than the medium replacement part or lower than the medium replacement part), and then put the washed rice into the holding part. It should be noted that after the rice is placed in the holding part, the rice and water It can be completely separated, the water can submerge a part of the rice, and the water can submerge all the rice.

In the boiling stage, the cooking cavity is heated at the first power adjustment ratio, and the water in the cooking cavity is boiling. At this time, the water in the cooking cavity will produce a lot of bubbles, and some of the bubbles will be stored in the medium replacement part to make the medium replacement part. The pressure increases, and under the action of the pressure, the water in the medium replacement part is discharged into the cooking cavity, so that the water level in the cooking cavity rises. Because the holding part communicates with the cooking cavity, the water in the medium replacement part flows into the cooking cavity. After the cavity, the water in the cooking cavity will flow into the holding part. At this time, the water level in the whole holding part will rise, and the water will submerge the rice and accelerate the gelatinization of the rice.

After the first time threshold, with the second power adjustment ratio cooking cavity, the cooking cavity stops boiling, the water vapor in the medium replacement part is cooled and liquefied, the pressure in the medium replacement part is reduced accordingly, and then the water in the cooking cavity will flow back The medium replacement part makes the water level in the holding part drop rapidly, so that the rice water is separated, and the gelatinization degree of the rice can be reduced at this time.
