Description

Technical Field

[0001] The present application relates to the technical field of food processing, and in particular to a food processing method, equipment and storage medium. Background Art

[0002] Food soaking refers to soaking dry ingredients (such as white fungus, shiitake mushrooms, bean curd, dried kelp or rice, grains, beans, dry rice noodles, etc.) in cold water to allow the dry ingredients to absorb water, expand and soften, so as to facilitate subsequent cooking or eating.

[0003] The current method of soaking food is to soak dry food ingredients in water for a certain period of time to complete the soaking process of dry food ingredients. However, it takes a long time to make dry food ingredients fully absorb water and expand. Alternatively, soaking in hot water can speed up the soaking process, which can easily affect the quality of the ingredients after soaking, resulting in a large loss of nutrients and a poor taste. Summary of the invention

[0004] The present application provides a food processing method, equipment and storage medium, which are used to solve the problem in the prior art that it takes a long time for dry food ingredients to fully absorb water, expand and soak, or affects the soaking quality.

[0014] The pulse electric field control module controls the heating module to heat the food and water in the food processing chamber to a preset first temperature and continue for a preset second time period, wherein the value range of the first temperature is 50°C-80°C.

[0015] In a possible implementation, after maintaining the food and water at the first temperature for a preset second time period, the method provided by the present application further includes:

[0016] Controlling the heating module to continue heating the food and water in the food processing chamber to the second temperature and continue heating for a preset third time period to cook the food;

[0017] Within a preset third time period, a voltage signal having a target pulse width and a target pulse frequency is applied to the first electrode and the second electrode so that the food and water between the first electrode and the second electrode are under a target electric field strength.

[0018] In a possible implementation, the preset third time period includes a plurality of continuous sub-periods, wherein for each sub-period, the later the timing of the plurality of sub-periods is, the smaller the proportion of the time period for applying the voltage signal to the first electrode and the second electrode is.

[0019] In a possible implementation, the preset third time period includes three consecutive sub-periods, and within the preset third time period, a voltage signal having a target pulse width and a target pulse frequency is applied to the first electrode and the second electrode so that the food and water between the first electrode and the second electrode are under a target electric field strength, including:

[0020] In each group of second pulse application periods in the first sub-period, a voltage signal having a target pulse width and a target pulse frequency and making the food and water between the first electrode and the second electrode be under a target electric field strength is applied to the first electrode and the second electrode, wherein a second time interval exists between each two adjacent groups of second pulse application periods;

[0021] In each group of third pulse application periods in the second sub-period, a voltage signal is applied to the first electrode and the second electrode, wherein a third time interval exists between each two adjacent groups of third pulse application periods, wherein the third time interval is greater than the second time interval, and the duration of the third pulse application period is less than the duration of the second pulse application period;

[0022] In the third sub-period, the voltage signal is stopped from being applied to the first electrode and the second electrode.

[0023] In a possible implementation, before the pulse electric field control module applies a voltage signal to the first electrode and the second electrode within the preset plurality of groups of first pulse application time periods, the method provided by the present application further includes:

[0024] In the food processing chamber, the food is soaked for a preset first time period.

[0025] In the second aspect, the present application also provides a food processing device, which includes a pulsed electric field control module, a food processing chamber, a first electrode, and a second electrode. The food processing device includes a pulsed electric field control module, a food processing chamber, a first electrode, and a second electrode. The first electrode and the second electrode are relatively spaced apart in the food processing chamber. The pulsed electric field control module is electrically connected to the first electrode and the second electrode, respectively. The pulsed electric field control module is used to execute the method provided in the first aspect of the present application.

[0028] The present application provides a food processing method, device and storage medium, wherein the pulse electric field control module applies a voltage signal having a target pulse width and a target pulse frequency to the first electrode and the second electrode within a preset plurality of first pulse application time periods, and makes the dry food and water between the first electrode and the second electrode be under a target electric field strength. Since the water soaked with dry food is usually a conductive medium, when the first electrode, the dry food and water and the second electrode are connected to form a loop to form an electric field within each first pulse application time period, the electric field between the first electrode and the second electrode generates a magnetic field, and the dry food soaked in the water is alternately acted upon by the electric field and the magnetic field, so that the cell membrane of the dry food is destroyed, and the permeability of the cell membrane is increased, so that water molecules can easily penetrate into the cell membrane, and the speed of water absorption of the food is greatly increased; and the permeability of the food cells is increased.

[0029] Furthermore, since there is a first time interval greater than the target pulse width between each two adjacent groups of first pulse application periods, the permeability of the cells of the food soaked in water will increase in each first time interval. The greater the permeability of the cells, the faster the food absorbs water when it is alternately acted upon by the electric field and the magnetic field. That is to say, the later the first pulse application period, the faster the food absorbs water. In this way, the water absorption speed and soaking efficiency of dry food are further improved until the food is restored to the quality state before drying. It can be understood that through the above method, the time for the food to fully absorb water, expand and soak is greatly saved, and the quality and taste of the soaked food are guaranteed.

[0040] The following is a detailed description of the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0041] The present application embodiment provides a food processing method, which is applied to a food processing device. The food processing device may be, but is not limited to, a health pot. Figure 1 As shown, the food processing device includes a pulse electric field control module 101, a food processing chamber 104, a first electrode 102, and a second electrode 103, wherein the first electrode 102 and the second electrode 103 are arranged in the food processing chamber 104 at a relative interval. Specifically, the first electrode 102 and the second electrode 103 can be arranged along the inner wall of the food processing chamber 104, or can be arranged at an angle to the inside of the food processing chamber 104, which is not limited here. The pulse electric field control module 101 is electrically connected to the first electrode 102 and the second electrode 103, respectively.

[0042] The pulse electric field control module 101 includes a processor and a pulse electric field generator, and the processor is used to control the pulse electric field generator to apply an electric field to the food processing chamber 104. The first electrode 102 can be a positive electrode, and the second electrode 103 can be a negative electrode, or the second electrode 103 can be a positive electrode and the first electrode 102 can be a negative electrode. The food processing chamber 104 has an opening, and dry food ingredients and water can be put into and taken out of the food processing chamber 104 through the opening. Exemplarily, the dry food ingredients can include but are not limited to white fungus, shiitake mushrooms, bean curd sticks, or kelp, etc., which are not limited here. Figure 2 As shown, the method provided in the embodiment of the present application includes:

[0043] S200: In the food processing chamber 104, the dry food is soaked for a preset first time period.

[0044] Exemplarily, the duration of the first time period ranges from 5 min to 1 h, and the soaking water temperature ranges from 0°C to 50°C. For example, the first time period can be 5 min, 20 min or 1 h, etc., which is not limited here; for example, the soaking water temperature can be 0°C, 20°C or 50°C, etc., which is not limited here. It can be understood that the preset first time period for soaking dry food ingredients can activate the activity of the cells of the dry food ingredients in advance and can pre-absorb water and swell for the first time period, so that the cells of the dry food ingredients initially have better permeability, laying a good foundation for subsequently increasing the water absorption rate. It should be noted that S200 can be omitted.

[0045] S201: The pulse electric field control module 101 applies a voltage signal having a target pulse width and a target pulse frequency to the first electrode 102 and the second electrode 103 within a plurality of preset first pulse application time periods, so that the food and water between the first electrode 102 and the second electrode 103 are under a target electric field strength. There is a first time interval greater than the target pulse width between each two adjacent first pulse application time periods.

[0046] It can be understood that the pulse electric field control module 101 applies a voltage signal of a preset target electric field strength to the dry food ingredients and water, and uses a higher voltage pulse electric field to perform a brief and strong electric shock on the cell membrane on the surface of the food ingredients to be absorbed, thereby inducing the formation of micropores (electroporation) in the cell membrane through the electric field. These micropores allow external liquids to penetrate into the food ingredients more easily, increasing the permeability of the cell membrane and promoting the rapid absorption of water by the food ingredients.

[0047] Exemplarily, the target electric field strength is measured by: obtaining the voltage difference |V1-V2| and the shortest distance d between an electrode 102 and a second electrode 103; dividing the voltage difference |V1-V2| by the shortest distance d to obtain the target electric field strength, such as, target electric field strength = (|V1-V2|) / d, kV), or, directly measuring the electric field parameters of the target electric field using an oscilloscope, wherein the periodic voltage signal includes the target electric field strength (the pulse electric field strength range is 10-50 kV / cm), the target electric field strength (the frequency is the number of working times per minute, Hz), and the target pulse width (the pulse width is the duration of each working time, μs).

[0048] In some embodiments, the target electric field strength ranges from 0.01 kV / cm to 5 kV / cm, the target pulse frequency ranges from 5 Hz to 100 Hz, and the target pulse width ranges from 10 μs to 50 μs. Exemplarily, the target electric field strength may be, but is not limited to, 0.01 kV / cm, 0.31 kV / cm, or 0.5 kV / cm, which is not limited herein. The target pulse frequency may be, but is not limited to, 5 Hz, 30 Hz, or 100 Hz, which is not limited herein, and the target pulse width may be 10 μs, 30 μs, or 50 μs, which is not limited herein.

[0049] In some embodiments, the total duration of each group of first pulse application periods is greater than or equal to the duration of the first duration interval, and the total duration of the first pulse application period ranges from greater than 1 min to less than 10 min. Optionally, the range of the first duration interval is greater than or equal to 50 ms and less than 10 min. For example, the total duration of the first pulse application period can be 2 min, then the first duration interval can be 1 min; the total duration of the first pulse application period can be 5 min, then the first duration interval can be 2 min; the total duration of the first pulse application period can be 10 min, then the first duration interval can be 5 min, etc., which is not limited here.

[0050] It can be but is not limited to 1 minute, 5 minutes or 10 minutes, and the first duration interval can be 1 minute, 5 minutes or 10 minutes. Figure 3 A waveform diagram of the voltage signal in S201 is shown.

[0051] In a method for processing dry food materials provided by an embodiment of the present application, the pulse electric field control module 101 applies a voltage signal having a target pulse width and a target pulse frequency to the first electrode 102 and the second electrode 103 within a preset plurality of first pulse application periods, and the voltage signal causes the dry food materials and water between the first electrode 102 and the second electrode 103 to be at a target electric field strength. Since the water soaked with dry food materials is usually a conductive medium, when the first electrode 102, the dry food materials and water, and the second electrode 103 are connected to form a loop to form an electric field within each first pulse application period, the electric field between the first electrode 102 and the second electrode 103 generates a magnetic field, and the dry food materials soaked in the water are alternately acted upon by the electric field and the magnetic field, so that the cell membrane of the dry food materials is destroyed, and the permeability of the cell membrane is increased, so that water molecules can easily penetrate into the cell membrane, and the speed of water absorption of the food materials is greatly increased; and the permeability of the food cells is increased.

[0052] Furthermore, since there is a first time interval greater than the target pulse width between each adjacent two groups of first pulse application periods, in each first time interval, the permeability of the cells of the dry food ingredients soaked in water will increase, and the greater the permeability of the cells, the water absorption rate will be increased again when the dry food ingredients are alternately acted upon by the electric field and the magnetic field, that is, the later the first pulse application period, the faster the water absorption rate of the dry food ingredients, so that the water absorption rate and the soaking efficiency of the dry food ingredients are further improved, until the food ingredients are restored to the quality state before drying. It can be understood that, through the above-mentioned method, the time for the dry food ingredients to fully absorb water, expand and soak is greatly saved, and the quality and edible taste of the soaked food ingredients are guaranteed. Taking Tremella as an example, after the inventor's test, the time for Tremella ingredients to fully absorb water, expand and soak is only 1h.

[0053] Specifically, Figure 4 As shown, S201 can be specifically implemented as S401-S404. Among them,

[0054] S401: The pulse electric field control module 101 applies a voltage signal having a target pulse width and a target pulse frequency to the first electrode 102 and the second electrode 103 during the Nth group of first pulse application periods, and causes the dry food and water between the first electrode 102 and the second electrode 103 to be at a target electric field strength, wherein N is an integer variable, and the initial value of N is 1, and the maximum value of N is the preset number of pulse groups.

[0055] S402: between two adjacent groups of first pulse application periods, within a preset first time interval that is continuous with the Nth group of first pulse application periods, stop applying voltage signals to the food and water.

[0056] S403: Determine whether the value of N reaches a preset number of pulse groups, if not, execute S404.

[0057] The preset number of pulse groups is greater than or equal to 2.

[0058] S404: Add 1 to the value of N, and return to execute S401.

[0059] In addition, Figure 1 As shown, the food processing device may further include a heating module 105, the heating module 105 is electrically connected to the pulse electric field control module 101, and the heating module 105 is in contact with the food processing chamber 104. Figure 5 As shown, after S101, the method provided in the embodiment of the present application further includes:

[0060] S202: The pulse electric field control module 101 controls the heating module 105 to heat the dry food and water in the food processing chamber 104 to a preset first temperature, and keeps the dry food and water at the first temperature for a preset second time, wherein the first temperature ranges from 50°C to 80°C. For example, the second time can be 5 minutes, 10 minutes, 15 minutes or 20 minutes, and the first temperature can be 50°C, 70°C or 80°C. It can be understood that soaking the dry food and water at the first temperature for the second time can make the dry food absorb water and expand more fully.

[0061] S203: Control the heating module 105 to continue heating the dry food and water in the food processing chamber 104 to the second temperature and continue heating for a preset third time period to cook the food.

[0062] Illustratively, the second temperature may be, but is not limited to, 90°C, 95°C or 100°C.

[0063] S204: Within a preset third time period, a voltage signal having a target pulse width and a target pulse frequency is applied to the first electrode 102 and the second electrode 103 so that the dry food and water between the first electrode 102 and the second electrode 103 are at a target electric field strength.

[0064] For example, the third preset time length may be 40 minutes, 60 minutes, or 70 minutes, etc., which is not limited here. The electric field between the first electrode 102 and the second electrode 103 can destroy the endosperm structure of the dry food material that has fully absorbed water, so that the nutrients inside the dry food material that has fully absorbed water are precipitated into the aqueous solution, so that the cooked food has a richer taste, a better taste, and a higher nutritional value.

[0065] Exemplarily, in S204, the preset third duration includes a plurality of continuous sub-periods, wherein for each sub-period, the later the timing of the plurality of sub-periods is, the smaller the duration of applying the voltage signal to the first electrode 102 and the second electrode 103 is. It can be understood that during the cooking process, the electric field between the first electrode 102 and the second electrode 103 can promote the precipitation of nutrients inside the dry food ingredients that have fully absorbed water into the aqueous solution. The earlier the time in the cooking stage, the more residual nutrients inside the dry food ingredients that have fully absorbed water, and vice versa. Therefore, the later the timing of the plurality of sub-periods is, the smaller the duration of applying the voltage signal to the first electrode 102 and the second electrode 103 is, which can save power consumption while allowing the nutrients inside the dry food ingredients to be fully precipitated into the aqueous solution.

[0066] Exemplarily, the preset third time length includes three consecutive sub-periods. For example, when the preset third time length is 60 minutes, the preset third time length may include three consecutive sub-periods, each sub-period including the first 20 minutes, the second 20 minutes, or the third 20 minutes.

[0067] In each group of second pulse application periods in the first sub-period, a voltage signal having a target pulse width and a target pulse frequency and making the dry food and water between the first electrode 102 and the second electrode 103 be under a target electric field strength is applied to the first electrode 102 and the second electrode 103, wherein a second time interval exists between each two adjacent groups of second pulse application periods. For example, in the first 20 minutes, a voltage signal having a second pulse application period of 3 minutes is applied to the first electrode 102 and the second electrode 103 every 1 minute.

[0068] In each group of third pulse application periods in the second sub-period, a voltage signal is applied to the first electrode 102 and the second electrode 103, wherein a third time interval exists between each two adjacent groups of third pulse application periods, wherein the third time interval is greater than the second time interval, and the duration of the third pulse application period is less than the duration of the second pulse application period; for example, in the second 20 minutes, a voltage signal with a second pulse application period of 1.5 minutes is applied to the first electrode 102 and the second electrode 103 every 3.5 minutes. In the third sub-period, the voltage signal is stopped from being applied to the first electrode 102 and the second electrode 103.

[0069] It can be seen that the proportion of the time when the first electrode 102 and the second electrode 103 apply the voltage signal in the third 20 minutes is smaller than the proportion of the time when the first electrode 102 and the second electrode 103 apply the voltage signal in the second 20 minutes, and the proportion of the time when the first electrode 102 and the second electrode 103 apply the voltage signal in the second 20 minutes is smaller than the proportion of the time when the first electrode 102 and the second electrode 103 apply the voltage signal in the first 20 minutes.

[0070] According to the inventor's test, 15g of unsoaked white fungus (i.e., dry food ingredients) was taken, 1000g of water was added, and soaked at room temperature for 20min (i.e., the preset first duration). Then, the white fungus and water were treated for 10min (i.e., the first pulse application period) using a voltage signal with a target electric field strength of 0.31kV / cm, a target pulse width of 30μs pulse width, and a target pulse frequency of 30Hz, and then treated for 10min (i.e., the first pulse application period) after an interval of 5min (i.e., the first duration interval), and then the heating module 105 was controlled to heat the white fungus and water to 70°C (i.e., the first temperature) so that the white fungus absorbs water for 15min (i.e., the preset second duration).

[0071] The heating module 105 is controlled to continue heating the Tremella and water in the food processing chamber 104 to 100°C, so that the Tremella and water are cooked at 100°C. In the first 20 minutes after the Tremella and water reach 100°C, a voltage signal with a second pulse application period of 3 minutes is applied to the first electrode 102 and the second electrode 103 every 1 minute. From 20 minutes to 40 minutes, a voltage signal with a second pulse application period of 1.5 minutes is applied to the first electrode 102 and the second electrode 103 every 3.5 minutes. From 40 minutes to 60 minutes, the voltage signal is stopped from being applied to the first electrode 102 and the second electrode 103, and the cooking temperature of 100°C is maintained. In the above manner, the total time required for processing Tremella is only 2 hours, saving 60% of the cooking time.

[0072] Similarly, when the food is rice, the above-mentioned steps and principles of S200-S204 can also be used to make the rice absorb water and soak, thereby increasing the water absorption speed of the rice; further, the heating module 105 can be controlled to continue heating the rice and water in the food processing chamber 104, so that the rice and water in the food processing chamber 104 are in the cooking stage, which also saves the cooking time of the rice.

[0073] In addition, the embodiment of the present application also provides a food processing device, which is configured in the pulse electric field control module 101 of the food processing equipment. It should be noted that the basic principle and technical effect of the food processing device provided in the embodiment of the present application are the same as those of the above-mentioned embodiments. For the sake of brief description, for parts not mentioned in the embodiment of the present application, reference can be made to the corresponding contents in the above-mentioned embodiments. The food processing equipment also includes a food processing chamber 104, a first electrode 102, and a second electrode 103. The first electrode 102 and the second electrode 103 are arranged in the food processing chamber 104 with relative intervals, and the pulse electric field control module 101 is electrically connected to the first electrode 102 and the second electrode 103, respectively. Figure 6 As shown, the device provided in the embodiment of the present application includes:
