Description

Technical Field

[0001] This application relates to the field of refrigerator technology, and in particular to a starch aging control method, device, refrigerator drawer, refrigerator, and readable medium. Background Technology

[0002] As a common chronic metabolic disease, diabetes requires dietary control as a core aspect of disease management. Starchy products such as rice, noodles, and steamed buns are staple foods. When heated and gelatinized, their starch is easily absorbed quickly, leading to a sharp rise in blood sugar after consumption. However, gelatinized starch can form resistant starch after cooling and aging, which can effectively reduce the glycemic index and is a key way to control blood sugar through staple foods.

[0003] In current home settings, starch aging can only be passively promoted by the refrigeration environment of a regular refrigerator. Such equipment is not specifically designed for starch aging and cannot provide a suitable aging environment for starch products, making it difficult to efficiently increase the content of resistant starch to achieve the ideal sugar control effect.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustration and has no specific meaning in itself. Therefore, "module" and "part" may be used interchangeably.

[0023] To address the problems mentioned in the background art, according to one aspect of the embodiments of this application, an embodiment of a starch aging control method is provided.

[0024] Optionally, in the embodiments of this application, the above-described starch retrogradation control method can be applied to, for example... Figure 1 The hardware environment shown consists of terminal 101 and server 103. Figure 1 As shown, server 103 is connected to terminal 101 via a network and can be used to provide services to the terminal or clients installed on the terminal. Database 105 can be set up on the server or independently of the server to provide data storage services for server 103. The network mentioned above includes, but is not limited to, wide area network, metropolitan area network or local area network. Terminal 101 includes, but is not limited to, refrigerator, PC connected to refrigerator, mobile phone, tablet computer, etc.

[0025] The starch aging control method in this embodiment can be executed by server 103, or it can be jointly executed by server 103 and terminal 101, such as... Figure 2 As shown, the method may include the following steps: Step S202: Obtain the current real-time temperature of the starch product and the preset temperature of the refrigerator drawer, wherein the starch product is stored in the refrigerator drawer, and the refrigerator drawer is an independent refrigeration area for the starch product in the refrigerator. Step S204: Based on the real-time temperature and the preset temperature, determine the starch aging control strategy that matches the current starch product. Different starch aging control strategies are used to construct different aging environments, and different aging environments are used to regulate the degree of aging of starch products. Step S206: Adjust the operating parameters of the refrigerator drawer according to the starch aging control strategy to control the degree of starch aging in starch products.

[0026] This application discloses a starch retrogradation control method, which is applied to a refrigerator equipped with a dedicated storage space for starch products. It is used to perform directional, precise, and adaptive control of the starch retrogradation process of starch products such as rice, steamed buns, and noodles, so as to increase the proportion of resistant starch formation and reduce the glycemic index, thereby serving the needs of blood sugar control and healthy eating.

[0027] In this embodiment, starch products refer to staple foods made primarily from rice and wheat flour, including but not limited to rice, steamed buns, noodles, and pastries, whose main component is starch, which can undergo gelatinization and aging reactions. A refrigerator drawer is a drawer-type cavity inside the refrigerator specifically designed to store starch products, isolated from other refrigerated spaces, to prevent cross-contamination of odors and contamination, and to provide a dedicated aging environment. The preset temperature of the refrigerator drawer refers to a pre-set target temperature suitable for starch product aging. The operating parameters of the refrigerator drawer refer to the adjustable environmental parameters of the independent refrigerated area, including cooling temperature, cooling fan speed, and ambient humidity. The degree of starch aging refers to the extent to which gelatinized starch in a starch product converts into resistant starch; the higher the degree of starch aging, the lower the glycemic index.

[0028] In step S202, the system continuously collects the real-time temperature of the starch products through temperature acquisition units deployed inside the independent cold storage area and in direct or indirect contact with the starch products, ensuring that the temperature data accurately reflects the thermal state of the starch products. Simultaneously, the system retrieves a preset temperature for the independent cold storage area from the storage unit; this preset temperature is the target temperature suitable for the starch aging reaction.

[0029] In step S204, the system compares and analyzes the real-time temperature of the starch product with the preset temperature of the refrigerator drawer. Based on the numerical relationship and trend between the two, it determines the stage of the starch product: high temperature waiting to cool down, cooling down, stable aging, or maintenance storage. Based on the determination result, the system automatically selects the starch aging control strategy that best matches the current thermal state and aging requirements of the starch product from the preset strategy library. This strategy includes the required combination of operating parameters and execution logic for the corresponding stage.

[0030] In step S206, the system issues control commands to the actuators in the independent cold storage area according to the selected starch aging control strategy, and performs real-time adjustment and closed-loop control of operating parameters such as refrigeration temperature, refrigeration airflow, and relative humidity. By creating a temperature, humidity, and airflow environment that matches the current state of the starch products, the system guides the gelatinized starch to convert into resistant starch, achieving precise control over the starch aging rate, saturation, and final degree, so that the starch products achieve the expected anti-saccharification effect and edible quality.

[0031] Through steps S202 to S206, this application provides an independent and dedicated cold storage area for starch products, and dynamically adjusts environmental operating parameters based on an adaptive matching aging control strategy between the real-time temperature of the starch products and the preset temperature to construct different aging environments. In turn, it achieves targeted regulation of the starch aging degree of starch products through different aging environments, thus solving the technical problem that existing refrigerator equipment cannot target the starch aging degree of starch products.

[0032] The following section further explains the determination logic and grading rules for starch aging control strategies.

[0033] In an optional embodiment, determining a starch aging control strategy that matches the current starch product based on the real-time temperature and a preset temperature includes: Step 1: Calculate the difference between the real-time temperature of the starch product and the preset temperature of the refrigerator drawer; Step 2a: If the difference is greater than or equal to the first temperature threshold, determine the starch aging control strategy that matches the current starch product as the activation aging control strategy. The activation aging control strategy is used to rapidly cool the starch product to meet the conditions for accelerated aging. Step 2b: If the difference is less than the first temperature threshold and greater than or equal to the second temperature threshold, determine the starch aging control strategy that matches the current starch product as the accelerated aging control strategy, wherein the accelerated aging control strategy is used to make the starch product age rapidly. Step 2c: If the difference is less than the second temperature threshold, determine the starch aging control strategy that matches the current starch product as the aging maintenance control strategy, wherein the aging maintenance control strategy is used to maintain the aging result of the starch product in the long term.

[0034] In this embodiment, the difference is the absolute value of the difference between the real-time temperature of the starch product and the preset temperature of the refrigerator drawer, used to quantify the degree of deviation of the starch product from the target aging temperature. The first temperature threshold is a system-preset high-temperature judgment threshold, used to distinguish between a high-temperature state and a state that has been initially cooled. In an optional embodiment, the first temperature threshold can be 10°C. The second temperature threshold is a system-preset stable state judgment threshold, used to distinguish between a cooled state and a state that has reached the stable target temperature. In an optional embodiment, the second temperature threshold can be 1.5°C. The aging control strategy refers to a rapid cooling strategy designed for high-temperature starch products, used to quickly enter the aging temperature range. The accelerated aging control strategy refers to a deep aging strategy designed for cooled starch products, used to maximize the promotion of starch conversion. The aging maintenance control strategy refers to a stable storage strategy designed for fully aged starch products, used to maintain the aging effect and preserve freshness.

[0035] In this embodiment, after obtaining the real-time temperature of the starch product and the preset temperature of the refrigerator drawer, the system performs numerical calculations to determine the difference between the real-time temperature and the preset temperature, and takes its absolute value as the temperature difference. This temperature difference reflects the distance between the starch product and the target aging temperature; a larger difference indicates a stronger need for cooling, while a smaller difference indicates that it is closer to stable aging conditions. The system compares the calculated temperature difference with a first temperature threshold and a second temperature threshold in sequence, performs graded judgment according to a three-segment interval, and matches the corresponding strategy: When the temperature difference is greater than or equal to the first temperature threshold, the system determines that the starch product is in a high-temperature state, the heat has not been dissipated, and it cannot directly enter the efficient aging process. Therefore, the current matching starch aging control strategy is determined to be the activation of the aging control strategy, which prioritizes rapid cooling.

[0036] When the temperature difference is less than the first temperature threshold and greater than or equal to the second temperature threshold, the system determines that the starch product has completed the initial cooling and entered the temperature range suitable for starch aging. Therefore, the current matching starch aging control strategy is determined to be the accelerated aging control strategy, and the product enters the full aging stage.

[0037] When the temperature difference is less than the second temperature threshold, the system determines that the temperature of the starch product has stabilized near the preset temperature and the starch aging reaction has been fully completed. Therefore, the current matching starch aging control strategy is determined to be the aging maintenance control strategy, and the system enters the long-term maintenance stage.

[0038] This application achieves a three-stage strategy classification through temperature difference, which makes the control logic completely match the actual thermal state of starch products, realizes step-by-step automatic control of start-up, acceleration and maintenance, and improves the stability, controllability and efficiency of the entire starch aging process.

[0039] In an optional embodiment, adjusting the operating parameters of the refrigerator drawer according to the starch aging control strategy includes: If the starch aging control strategy that matches the current starch product is determined to be the activation aging control strategy, the refrigerator drawer is controlled to run at a first cooling temperature, a first cooling fan speed, and a first humidity for a first duration, so as to reduce the temperature of the starch product to meet the conditions for accelerated aging within the first duration.

[0040] In this embodiment, the first cooling temperature refers to the target cooling temperature executed under the aging control strategy, used to achieve rapid cooling. In an optional embodiment, the first cooling temperature can be -18℃. The first cooling air velocity refers to the air supply velocity configured under the aging control strategy, taking into account both cooling efficiency and the surface condition of the starch product. In an optional embodiment, the first cooling air velocity can be 0.2m / s. The first humidity refers to the relative humidity maintained under the aging control strategy, preventing the starch product from rapidly losing water, cracking, frosting, or damaging its surface. In an optional embodiment, the first humidity can be 85%±3%. The first duration refers to the preset running time of the aging control strategy, ensuring that the temperature of the starch product drops to a range suitable for accelerated aging. In an optional embodiment, the first duration can be 1 hour. The accelerated aging condition refers to the temperature condition under which the starch product temperature drops to a level outside the high-temperature range, allowing it to enter a stable and efficient starch aging process. This is the basis for determining the end of the start-up phase and the beginning of the accelerated phase.

[0041] In this embodiment, when the aging control strategy is initiated, the system sends control commands to the refrigeration module, fan speed adjustment module, and humidity control module of the independent cold storage area, setting the environmental parameters to a first refrigeration temperature, a first refrigeration fan speed, and a first humidity level, causing the cavity to quickly enter the aging initiation working mode. The system maintains the above parameters stably for a first duration. During this period, the refrigeration module continuously outputs cooling, the fan speed module delivers air evenly at the first fan speed to avoid localized overcooling or drying, and the humidity module maintains the first humidity level to protect the quality of the starch products. The entire process rapidly and gently lowers the temperature of the starch products, preventing surface cracking and taste deterioration due to sudden cooling and low humidity. After the system time reaches the first duration, it determines that the temperature of the starch products has dropped to meet the conditions for accelerated aging. The aging control strategy is then completed, and the system automatically enters a state of waiting to switch to the next control strategy, preparing for subsequent accelerated aging.

[0042] For example, let T0 be the real-time temperature of the starch product and T1 be the preset temperature of the refrigerator drawer. The temperature difference between them is ΔT = |T0 = T1|. When ΔT ≥ 10℃ (i.e., the first temperature threshold), the refrigerator drawer cooling temperature is set to TC1 = -18℃ (i.e., the first cooling temperature), the cooling fan speed is VC1 = 0.2 m / s (i.e., the first cooling fan speed), the humidity control is RC1 = 85% ± 3% (i.e., the first humidity), and the running time is t1 = 1 hour (i.e., the first duration). After time t1 is reached, if ΔT < 10℃, the accelerated aging control strategy is executed; otherwise, the initial aging control strategy continues. Alternatively, if ΔT < 10℃ is detected during the initial aging control strategy, the system immediately switches to the accelerated aging control strategy.

[0043] This application rapidly cools down starch products while ensuring their appearance and edibility, allowing them to quickly enter the suitable temperature range for starch aging, thus providing the necessary prerequisite for subsequent efficient and complete starch aging.

[0044] In an optional embodiment, adjusting the operating parameters of the refrigerator drawer according to the starch aging control strategy further includes: When the starch aging control strategy matching the current starch product is determined to be an accelerated aging control strategy, the refrigerator drawer is controlled to run at a second cooling temperature, a second cooling fan speed, and a second humidity for a second duration to fully convert the gelatinized starch in the starch product into aged starch. The second cooling temperature is greater than the first cooling temperature, the second cooling fan speed is greater than the first cooling fan speed, the second humidity is less than the first humidity, and the second duration is greater than the first duration.

[0045] In this embodiment, the second cooling temperature refers to the stable cooling temperature under the accelerated aging control strategy, providing the optimal thermodynamic environment for the starch aging reaction. In an optional embodiment, the second cooling temperature can be 4°C. The second cooling air velocity refers to the stable air velocity under the accelerated aging control strategy, ensuring uniform cavity temperature and preventing local overheating or undercooling. In an optional embodiment, the second cooling air velocity can be 0.4 m / s. The second humidity refers to the stable humidity under the accelerated aging control strategy, maintaining the moisture content of the starch product and ensuring sufficient starch aging. In an optional embodiment, the second humidity can be 80% ± 3%. The second duration refers to the continuous operation duration of the accelerated aging control strategy, ensuring that the gelatinized starch is fully converted into resistant starch. In an optional embodiment, the second duration can be 12 hours. Gelatinized starch refers to starch formed after heating, which absorbs water, swells, has a loose structure, and is easily digested and absorbed by the human body, rapidly raising blood sugar levels. Aged starch refers to resistant starch formed after gelatinized starch has rearranged under cooling and stable temperature and humidity, resulting in a dense structure and difficult digestibility, significantly reducing the glycemic index.

[0046] In this embodiment, when the system determines that it has entered the accelerated aging control strategy, the system adjusts the operating parameters of the independent refrigeration area to a second refrigeration temperature, a second refrigeration fan speed, and a second humidity level, forming a stable, uniform microenvironment most conducive to starch aging. The system maintains these parameters continuously for a second duration. During this period, the internal temperature, fan speed, and humidity remain highly stable, providing a continuous and consistent environment for starch molecule rearrangement and the aging reaction. This allows the gelatinized starch inside the starch product to gradually and fully transform into resistant starch, continuously increasing the degree of aging and reducing the glycemic index. During the accelerated aging stage, the parameters satisfy the following logical relationships: the second refrigeration temperature is greater than the first refrigeration temperature to avoid excessively low temperatures inhibiting the aging reaction; the second refrigeration fan speed is greater than the first refrigeration fan speed to improve the uniformity of the cavity; the second humidity is less than the first humidity to match the moisture requirements of deep aging; and the second duration is greater than the first duration to ensure sufficient reaction time. These relationships collectively ensure that starch aging proceeds fully, efficiently, and stably.

[0047] For example, when 1.5℃ (the second temperature threshold) ≤ ΔT < 10℃ (the first temperature threshold), the refrigerator drawer cooling temperature is set to TC2 = 4℃ (the second cooling temperature), the cooling fan speed is VC2 = 0.4m / s (the second cooling fan speed), the humidity is controlled at RC2 = 80% ± 3% (the second humidity), and the running time is t2 = 12h (the second duration). After time t2 is reached, if ΔT < 1.5℃, the aging maintenance control strategy is executed; otherwise, the accelerated aging control strategy continues. Alternatively, if ΔT < 1.5℃ is detected during the execution of the accelerated aging control strategy, the system immediately switches to the aging maintenance control strategy.

[0048] This application maintains a stable and suitable environment for a long time, maximizing the conversion of gelatinized starch into resistant starch, significantly improving the degree of starch aging, effectively reducing the glycemic index of starch products, and achieving the core anti-glycemic effect.

[0049] In an optional embodiment, adjusting the operating parameters of the refrigerator drawer according to the starch aging control strategy further includes: When the starch aging control strategy matching the current starch products is determined to be the aging maintenance control strategy, the refrigerator drawer is controlled to continuously operate at a third cooling temperature, a third cooling fan speed, and a third humidity to store fully aged starch products. The third cooling temperature is less than or equal to the second cooling temperature, the third cooling fan speed is less than the first cooling fan speed, and the third humidity is less than or equal to the second humidity.

[0050] In this embodiment, the third cooling temperature refers to the cooling temperature under the aging maintenance control strategy, used to maintain the aging state and achieve freshness. In an optional embodiment, the third cooling temperature can be 4°C. The third cooling air velocity refers to the low air velocity under the aging maintenance control strategy, reducing energy consumption, minimizing moisture loss, and avoiding environmental disturbance. In an optional embodiment, the third cooling air velocity can be 0.05 m / s. The third humidity refers to the relative humidity under the aging maintenance control strategy, used to maintain the quality of starch products for a long time. In an optional embodiment, the third humidity can be 80% ± 3%.

[0051] In this embodiment, when the system determines that the starch product has fully aged and enters the aging maintenance control strategy, the system adjusts the operating parameters of the independent cold storage area to the third refrigeration temperature, the third refrigeration fan speed, and the third humidity, entering a low-disturbance, low-energy-consumption, and high-stability maintenance mode. The system maintains these parameters long-term, maintaining the preset temperature while using extremely low fan speeds to avoid drastic fluctuations in the internal environment, and matching humidity to prevent the starch product from drying out, hardening, or deteriorating. This ensures the stability of the formed resistant starch, preventing retrogradation and ensuring that the sugar control effect does not decrease. The parameters in the aging maintenance stage satisfy the following logical relationships: the third refrigeration temperature is less than or equal to the second refrigeration temperature to ensure storage safety; the third refrigeration fan speed is less than the first refrigeration fan speed to reduce disturbance and moisture loss; and the third humidity is less than or equal to the second humidity to meet long-term storage requirements.

[0052] For example, when ΔT < 1.5℃, the refrigerator drawer cooling temperature is set to TC3 = 4℃ (i.e., the third cooling temperature), the cooling fan speed is VC3 = 0.05m / s (i.e., the third cooling fan speed), and the humidity is controlled at RC3 = 80% ± 3% (i.e., the third humidity), thus entering the long-term storage maintenance stage.

[0053] This application aims to achieve long-term stable storage of starch products while maintaining the degree of starch aging and anti-sugar effect, thus taking into account sugar control effect, food quality and storage safety.

[0054] Based on the aforementioned embodiments, this application further provides methods for real-time detection of powder aging degree, calculation of glycemic index, and personalized staple food intake recommendation, which will be described in detail below.

[0055] In an optional embodiment, the method further includes, during the process of controlling starch aging in starch products: Step 1: Detect the resistant starch content of starch products at predetermined intervals; Step 2: Calculate the latest glycemic index of starch products based on resistant starch content; Step 3: Obtain the target subject's blood glucose and exercise data, and determine the recommended intake of starch products for the target subject based on the glycemic index, blood glucose data, and exercise data.

[0056] In this embodiment, the resistant starch content is a direct indicator of the degree of starch retrogradation; the higher the content, the better the blood sugar control effect. The glycemic index (GI) measures the magnitude of postprandial blood glucose rise caused by food; a lower GI value indicates better blood sugar control. The target audience refers to users consuming this starch product, especially suitable for patients with type 2 diabetes, people with high blood sugar, and those exercising to control blood sugar. Blood glucose data refers to the target audience's fasting blood glucose, postprandial blood glucose, and daily blood glucose fluctuation range. Exercise data refers to the target audience's exercise duration, intensity, steps, and calories burned, reflecting energy metabolism. The recommended intake is a safe and scientifically sound amount of staple food to consume per meal and daily, taking into account the degree of starch product retrogradation and the user's physical condition.

[0057] In this embodiment, throughout the starch aging control process, the system periodically initiates the detection process according to a preset time cycle to obtain the current resistant starch content of the starch product, achieving full monitoring and traceability of the aging degree. For example, when executing the aging initiation control strategy, the system starts the detection process every 1 hour; when executing the accelerated aging control strategy, the system starts the detection process every 12 hours; and when executing the aging maintenance control strategy, the system starts the detection process every 24 hours. These time intervals can be set according to actual needs.

[0058] In this embodiment of the application, the system calculates the current glycemic index of the starch product based on a preset mathematical model and with the resistant starch content as the input parameter, so as to intuitively reflect its sugar control ability. The mathematical model is GI=82-1.8×RS%, where GI is the glycemic index and RS is the resistant starch content.

[0059] In this embodiment, the system can determine the recommended intake of starch products based on the glycemic index (GI). For example, when the GI range is 75–85, the recommended intake is 60g per meal, with a total daily intake of 180g; when the GI range is 65–74, the recommended intake is 80g per meal, with a total daily intake of 240g; and when the GI range is 55–64, the recommended intake is 100g per meal, with a total daily intake of 300g.

[0060] The above recommendations can be simultaneously displayed on the user's app and the refrigerator's display screen. The glycemic index (GI) of starch products can be displayed using different colored indicator lights. For example, products with a GI range of 75–85 are classified as high GI and displayed in red; products with a GI range of 65–74 are classified as medium GI and displayed in yellow; and products with a GI range of 55–64 are classified as low GI and displayed in green.

[0061] In this embodiment of the application, the system can also obtain real-time blood glucose data and exercise data of the target object through local input, binding of health devices, association of applications, etc., to establish a personalized health profile. The system integrates and analyzes the glycemic index, blood glucose data, and exercise data and performs intelligent calculations. Taking into account the anti-glycemic effect of starch products, the user's blood glucose level, and energy consumption, the system determines the recommended intake per meal and the total daily intake suitable for the target object, so as to achieve scientific and personalized dietary guidance.

[0062] For example, if a user's blood glucose level 2 hours after a meal is >10 mmol / L, the optimized recommended intake is to reduce it by 20%, and it is suggested that the user choose staple foods with a higher resistant starch content. Alternatively, it could be suggested that while reducing staple food intake, the user increase the intake of high-quality protein and low glycemic index foods to replace part of the energy supply at each meal. If a user's fasting blood glucose level is >7 mmol / L, it is recommended that the user reduce their staple food intake at dinner by 30%, and it is suggested that the user increase their exercise intensity half an hour after the meal. If the user increases their exercise intensity, the increase in staple food intake should be calculated based on the amount of exercise expenditure. For a 70kg user with a daily total CHO target of 140g (47g / meal) and a basic steamed bun intake (GI=65) of 80g / meal (CHO 40g), if the user jogs for 30 minutes, burning 245kcal, the extra steamed bun intake would be 122.5g. The correction algorithm is: safe extra intake = 0.6min (theoretical intake * correction factor, remaining CHO intake per meal). After correction, the safe intake is 44.1g for medium-GI steamed buns and 73.5g for low-GI steamed buns. High-GI steamed buns are not recommended for patients, with a correction factor of 0.4; medium-GI steamed buns have a correction factor of 0.6; and low-GI steamed buns have a correction factor of 1.

[0063] This application enables the monitoring of starch retrogradation, the quantification of glycemic index, and the recommendation of intake, forming a complete closed loop of retrogradation control, status feedback, and dietary guidance, significantly improving the scientific nature and convenience of blood glucose management.

[0064] In an optional embodiment, detecting the resistant starch content of the starch product at predetermined intervals includes: Step 1: Turn on the near-infrared light source inside the refrigerator and use the near-infrared light source to irradiate the starch products; Step 2: Detect the first absorption value of starch products to the first near-infrared light and the second absorption value to the second near-infrared light. The first near-infrared light is the near-infrared light with a wavelength of the first wavelength in the spectrum emitted by the near-infrared light source, and the second near-infrared light is the near-infrared light with a wavelength of the second wavelength in the spectrum emitted by the near-infrared light source. The first wavelength and the second wavelength are the light wavelengths in which resistant starch exhibits significant characteristic absorption. Step 3: Calculate the resistant starch content based on the first and second absorbance values.

[0065] In this embodiment, the near-infrared light source refers to a light-emitting component capable of emitting near-infrared light, which can excite the characteristic absorption signal of starch components. The first near-infrared light refers to near-infrared light with a wavelength of 1150 nm (i.e., the first wavelength), and the second near-infrared light refers to near-infrared light with a wavelength of 1980 nm (i.e., the second wavelength). The first absorption value refers to the absorption intensity of resistant starch for near-infrared light with a wavelength of 1150 nm, denoted as A1150, and the second absorption value refers to the absorption intensity of resistant starch for near-infrared light with a wavelength of 1980 nm, denoted as A1980.

[0066] In this embodiment, each time the resistant starch content in a starch product is detected, the system drives the near-infrared light source to turn on and operate stably, ensuring that the light is uniformly irradiated onto the surface of the starch product. The system, through a detection module, simultaneously acquires the first absorption value A1150 of the starch product to a first wavelength of first near-infrared light and the second absorption value A1980 of a second wavelength of second near-infrared light. The system inputs the first absorption value A1150 and the second absorption value A1980 into a preset quantitative calculation model, and calculates the current resistant starch content of the starch product through an algorithm, achieving high-precision, non-destructive, real-time detection. The specific quantitative calculation model is as follows: RS = 0.75 * A1150 + 1.32 * A1980 - 3.8 This application uses near-infrared dual-wavelength spectroscopy to achieve non-destructive, rapid, and accurate detection of resistant starch content, and can monitor the degree of starch retrogradation in real time throughout the process, providing reliable data support for glycemic index calculation and intake recommendations.

[0067] This application solves the technical problem that existing refrigerator equipment cannot directionally control the degree of starch aging in starch products by providing an independent and dedicated cold storage area for starch products and by adaptively matching the real-time temperature of starch products with the preset temperature and dynamically adjusting the environmental operating parameters to construct different aging environments. In turn, different aging environments are used to achieve targeted control of the degree of starch aging in starch products, thus solving the technical problem that existing refrigerator equipment cannot directionally control the degree of starch aging in starch products.

[0068] This application can also develop specific starch aging control programs for different types of starch products. Specifically, the following steps are performed: Step 1: Identify the types of starch products placed in the separate refrigerated area; Step 2: Match the corresponding dedicated starch aging control strategy from the preset aging mode library according to the type of starch product; Step 3: According to the dedicated starch aging control strategy, adjust the operating parameters of the independent cold storage area to achieve targeted control of the starch aging degree of this type of starch product.

[0069] In this embodiment, the starch products include staple foods such as rice, steamed buns, noodles, rice cakes, pastries, and bread, where starch structure and moisture content vary significantly. The preset aging mode library refers to the optimal combinations of temperature, humidity, wind speed, and time stored in advance by the system for different starch products. The dedicated starch aging control strategy refers to a specific control process corresponding to each product category to maximize the proportion of resistant starch. Targeted regulation refers to differentiated and precise aging control based on the differences in gelatinization characteristics, moisture content, and aging rate of different starch categories.

[0070] In this embodiment, the system determines the type of starch product—rice, steamed buns, noodles, or other types—by allowing the user to manually select the product category through the refrigerator's interface or a mobile app, or by automatically identifying the product through image recognition or near-infrared spectroscopy. The system compares the identified category information with a preset aging mode library and retrieves a dedicated control strategy perfectly matched to that category. Different categories correspond to different strategies: rice uses a rapid cooling-medium temperature aging mode; steamed buns use a high-humidity slow cooling-long-term constant temperature aging mode; noodles use a uniform temperature low-airflow-medium-humidity stable aging mode; and rice cakes use a low-temperature slow aging-high-humidity soft-keeping mode. Based on the matched strategy, the system automatically configures the cooling temperature, cooling fan speed, relative humidity, and operating time to provide the most suitable aging environment for the starch product, allowing the starch to undergo molecular rearrangement along the optimal path, forming high-content resistant starch. The system monitors the starch aging degree in real-time or periodically. Once the target resistant starch content is reached, it automatically switches to a maintenance mode to keep the aging state stable.

[0071] This application achieves differentiated and targeted regulation based on the type of starch product, enabling staple foods with different starch structures to achieve the best aging effect, significantly improving the resistant starch formation rate, and making the sugar control effect more stable and targeted.

[0072] This application also provides a method for controlling starch aging based on an electric field, comprising the following steps: Step 1: Place the starch product in a separate refrigerator compartment. Step 2: Control the independent cold storage area to maintain the preset temperature and humidity environment for starch aging; Step 3: Apply a low-frequency weak electric field in the independent cold storage area to accelerate the rearrangement of starch molecules with the help of the electric field; Step 4: Based on the duration and intensity of the electric field, the degree of starch aging in starch products is controlled in a targeted manner.

[0073] In this embodiment, the low-frequency weak electric field refers to a safe weak electric field with a frequency of 10Hz-1kHz and a field strength of 100-500V / m, which does not affect food safety. Electric field-assisted aging refers to accelerating the aging reaction by driving the polar molecules of starch to align in a specific direction using an electric field.

[0074] In this embodiment, the user places the cooked starch product into a dedicated drawer, closes the cavity to form an independent, enclosed space, and avoids external environmental interference. The system activates the cooling, humidity control, and fan speed adjustment modules to maintain the independent area at preset aging temperature, humidity, and fan speed conditions, creating a stable basic environment. The system activates the electrode modules located on the upper and lower sides of the drawer, applying an intermittent low-frequency weak electric field: the electric field is turned on for a period of time, then turned off for a period of time, repeating this cycle. The weak electric field can lower the energy barrier for starch molecule rearrangement, allowing gelatinized starch to be converted into resistant starch more quickly and orderly. The system controls the total duration of the electric field based on the type of starch product and the target sugar control intensity, and turns off the electric field output after the duration is reached. Maintaining a stable temperature and humidity environment preserves the already formed high-resistant starch state, ensuring food quality and sugar control effect.

[0075] Under the same temperature and humidity conditions, an electric field can significantly accelerate the starch aging rate, increase the proportion of resistant starch, and achieve a faster, stronger, and more stable directional aging effect.
