[0002] With the improvement of living standards, consumers' demand for fresh and healthy food continues to increase. Fresh-cut vegetables are becoming more and more popular as convenient, ready-to-eat healthy foods. However, fresh-cut vegetables are easily contaminated by microorganisms and oxidized by air during storage and transportation, resulting in quality degradation, nutrient loss and shortened shelf life.

It can be seen that the present invention monitors the respiration rate of fresh-cut vegetables in real time during the storage process, and understands the fresh-keeping state of the vegetables in real time, so as to determine whether it is necessary to ozone the fresh-cut vegetables again, thereby improving the fresh-keeping effect when storing fresh-cut vegetables. Therefore, the present invention can improve the fresh-keeping effect when storing fresh-cut vegetables and reduce the damage rate of fresh-cut vegetables. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Reference Figure 1 FIG. 1 is a flow chart of a fresh-cut vegetable storage method based on gaseous ozone treatment provided by an embodiment of the present invention. In this embodiment, the fresh-cut vegetable storage method based on gaseous ozone treatment includes: S1. Start a pre-built ozone conditioning system, wherein the ozone conditioning system includes an ozone generator, a constant temperature storage room, a test box, a gas exhauster and a carbon dioxide detector.

[0024] In the embodiment of the present invention, the system for regulating the amount of gaseous ozone used in the storage process of fresh-cut vegetables is an ozone regulating system, and the ozone regulating system includes an ozone generator, a constant temperature storage chamber, a test box, a gas exhauster and a carbon dioxide detector. Fresh-cut vegetables are fruit and vegetable products made from fresh fruits and vegetables, which have been subjected to a series of processes such as grading, washing, trimming, peeling and cutting.

[0025] It should be explained that an ozone generator is a device for producing ozone gas. Optionally, a WH-G-2 ozone generator is used as an ozone generator. A constant temperature storage room is a warehouse that can maintain a constant temperature. A test box is a closed iron box used to test a concentration detection sample set and a time detection sample set. A gas discharger is a device including a gas storage tank, a pressure reducing valve and a transmission pipeline. A gas storage tank is a high-pressure gas cylinder that stores inert gas. Optionally, a high-pressure nitrogen cylinder is used as a gas storage tank. The pressure reducing valve is located at the connection between the gas storage tank and the transmission pipeline. Its main function is to reduce the pressure of the high-pressure inert gas in the gas storage tank and evenly transmit it to the transmission pipeline. The transmission pipeline is a gas transmission pipeline. Its main function is to connect the gas storage tank with the reaction storage chamber, so that gas interaction occurs between the gas storage tank and the reaction storage chamber. A carbon dioxide detector is an instrument for detecting carbon dioxide concentration. For the specific application of the reaction storage chamber, the concentration detection sample set and the time detection sample set, please refer to the subsequent embodiments.

[0026] S2. Obtain a vegetable sample set, wherein the vegetable sample set includes a plurality of vegetable samples, classify the plurality of vegetable samples by test mode, and obtain a concentration detection sample set and a time detection sample set.

[0027] It should be explained that the vegetable sample set is a collection of multiple vegetable samples, and the vegetable types of the vegetable samples are the same as the vegetable types of the fresh-cut vegetable set in the subsequent embodiments.

[0028] For example, Xiao Zhang is a processor in a fresh-cut vegetable factory. The factory now plans to store certain types of fresh-cut vegetables (such as tomatoes or cucumbers). In order to ensure the controllability of gaseous ozone treatment during the storage of fresh-cut vegetables, Xiao Zhang purchases fresh-cut vegetables from a farm in advance and takes a certain quality of fresh-cut vegetables as vegetable samples for testing, so as to obtain the optimal ozone concentration and target ozone time suitable for storing fresh-cut vegetables in advance, which is convenient for the subsequent formal storage of fresh-cut vegetables.

[0029] It should be explained that the concentration detection sample set consists of p concentration detection samples, and the time detection sample set consists of q time detection samples. The concentration detection samples are vegetable samples used to obtain the optimal ozone concentration in the future. The time detection samples are vegetable samples used to obtain the maximum ozone time and the minimum ozone time in the future.

[0030] It should be understood that the classification of multiple vegetable samples into test modes means classifying multiple vegetable samples according to subsequent test purposes. For example, the subsequent concentration test requires 30 concentration detection samples and the time test requires 70 time detection samples. Therefore, 100 cucumber samples are divided into 30 concentration detection samples and 70 time detection samples. The 30 concentration detection samples are used for subsequent concentration tests, and the 70 time detection samples are used for subsequent time tests.

[0031] S3. Utilize the concentration detection sample set, the ozone generator and the test box to obtain the optimal ozone concentration, introduce the optimal ozone concentration into the ozone generator, and obtain the target ozone generator.

[0032] In detail, the method of obtaining the optimal ozone concentration by using a concentration detection sample set, an ozone generator and a test box includes: Among them, the concentration detection sample set includes p concentration detection samples; Acquire a concentration test set, wherein the concentration test set includes p ozone concentrations, pair the p ozone concentrations with the p concentration detection samples to obtain p concentration test groups, wherein each of the p concentration test groups includes an ozone concentration and a concentration detection sample, and the ozone concentrations correspond to the concentration detection samples one by one; The following operations are performed for each of the p concentration test groups: placing the concentration test samples in the concentration test group into the test box to obtain a primary test box; The ozone concentration in the concentration test group is introduced into the ozone generator to obtain an updated ozone generator; Starting a renewal ozone generator for generating renewal ozone, using the started renewal ozone generator to deliver renewal ozone to the primary test box, taking the time of starting the renewal ozone generator as the starting point and recording the time in real time to obtain a concentration test time, when the concentration test time is equal to a preset first time threshold, turning off the renewal ozone generator to obtain a concentration test box, and when the concentration test time is equal to a preset second time threshold, using the concentration test box to obtain a concentration test sample; Use concentration test samples to obtain ethylene concentration, acetaldehyde concentration, conductivity, hardness and brittleness; Calculate the concentration evaluation value using ethylene concentration, acetaldehyde concentration, conductivity, hardness, brittleness and pre-built concentration evaluation functions; Summarize the concentration evaluation values ​​to obtain a concentration evaluation value set, and use the concentration evaluation value set to obtain an optimal evaluation value, wherein the optimal evaluation value is the largest concentration evaluation value in the concentration evaluation value set; The ozone concentration corresponding to the optimal evaluation value is taken as the optimal ozone concentration.

[0033] It should be explained that the concentration test set is a set of all selectable ozone concentrations in the ozone concentration control system of the ozone generator. Ozone concentration refers to the concentration of ozone generated by the ozone generator. The concentration test group consists of an ozone concentration and a concentration test sample. The primary test box refers to the test box in which the concentration test sample is placed. The update ozone generator refers to the ozone generator into which the ozone concentration is introduced. The update ozone refers to the gaseous ozone generated by the update ozone generator.

[0034] It should be understood that the ozone generator is equipped with an ozone concentration control system. After the ozone concentration is introduced into the ozone concentration control system, the ozone generator can produce gaseous ozone of the said ozone concentration.

[0035] Importantly, the concentration test time refers to the time taken from the start of the renewal ozone generator and the real-time recording of the time, and the end point is the recorded time, and the time value is obtained by subtracting the start point from the end point. For example, if the renewal ozone generator is started at 8:00, then at 8:05, the concentration test time is 5 minutes, and at 8:10, the concentration test time is 10 minutes. The first time threshold and the second time threshold are related to the type and nature of the vegetables and are set by the processor. The concentration test box refers to the primary test box to which the renewal ozone is delivered. The concentration test sample refers to the concentration test sample after ozone treatment in the concentration test box.

[0036] In detail, the method of using the concentration test sample to obtain ethylene concentration, acetaldehyde concentration, conductivity, hardness and brittleness includes: acquiring a first test sample, a second test sample, and a third test sample based on the concentration test sample; placing a first test sample into a pre-constructed gas sampling bag to obtain a target sampling bag, and using the target sampling bag to obtain the gas to be tested; Performing gas chromatography analysis on the gas to be tested to obtain the test ethylene concentration and the test acetaldehyde concentration; Respectively comparing the tested ethylene concentration with a preset ethylene concentration error threshold and the tested acetaldehyde concentration with a preset acetaldehyde concentration error threshold; If the tested ethylene concentration is less than the ethylene concentration error threshold and the tested acetaldehyde concentration is less than the acetaldehyde concentration error threshold, the tested ethylene concentration is taken as the ethylene concentration and the tested acetaldehyde concentration is taken as the acetaldehyde concentration; Performing a testing operation on the second test sample using a pre-built texture analyzer to obtain hardness and brittleness; A pre-built conductivity meter is used to perform a detection operation on the third test sample to obtain conductivity.

[0037] It should be explained that obtaining the first test sample, the second test sample and the third test sample based on the concentration test sample means dividing the concentration test sample into three equal parts according to mass to obtain the first test sample, the second test sample and the third test sample.

[0038] It should be understood that the gas sampling bag is a sampling bag for collecting gas. The target sampling bag refers to the gas sampling bag into which the first test sample is placed. The use of the target sampling bag to obtain the gas to be tested means that the first test sample will gradually volatilize volatile organic compounds in the target sampling bag, and the volatile organic compounds will diffuse into the gas in the target sampling bag, and the gas in the target sampling bag is collected to obtain the gas to be tested.

[0039] It should be explained that the texture analyzer is an instrument that can perform physical property analysis on the second test sample, and the conductivity meter is an instrument that measures the conductivity of the third test sample by an electrochemical measurement method.

[0040] It is understandable that the technology of performing gas chromatography analysis on the gas to be tested, the technology of using a pre-built texture analyzer to perform detection operations on the second test sample, and the technology of using a pre-built conductivity meter to perform detection operations on the third test sample are all existing technologies and will not be repeated here.

[0041] It should be explained that the test ethylene concentration and the test acetaldehyde concentration are the concentrations of ethylene and acetaldehyde in the gas to be tested. The ethylene concentration error threshold and the acetaldehyde concentration error threshold are related to the type and nature of the vegetable sample and are set by the processor. The ethylene concentration and the acetaldehyde concentration are the test ethylene concentration and the test acetaldehyde concentration when the test ethylene concentration is less than the ethylene concentration error threshold and the test acetaldehyde concentration is less than the acetaldehyde concentration error threshold, respectively. The hardness and brittleness reflect the freshness of the second test sample. The higher the hardness and brittleness, the higher the freshness of the second test sample, that is, the better the preservation effect of the ozone concentration corresponding to the second test sample.

[0042] It should be understood that when the cell membrane of the third test sample is damaged, the intracellular substances flow out and the conductivity increases, that is, the conductivity can reflect the membrane permeability of the third test sample. When the conductivity exceeds the conductivity threshold, it means that the third test sample is damaged, that is, the ozone concentration corresponding to the third test sample is not suitable for preservation.

[0043] In detail, the concentration evaluation function is as follows: , in, is the concentration evaluation value, is the ethylene concentration, is the acetaldehyde concentration, is the hardness, For brittleness, is the conductivity, is the preset conductivity threshold, and are the preset first ethylene coefficient and second ethylene coefficient, and are the preset first acetaldehyde coefficient and the second acetaldehyde coefficient.

[0044] It should be explained that the conductivity threshold, the first ethylene coefficient, the second ethylene coefficient, the first acetaldehyde coefficient and the second acetaldehyde coefficient are all related to the type and properties of the vegetable sample and are set by the processor.

[0045] It should be explained that the concentration evaluation value reflects the freshness of the concentration test sample after ozone treatment. The higher the concentration evaluation value, the fresher the concentration test sample, that is, the ozone concentration corresponding to the concentration evaluation value is more suitable for preservation. The optimal evaluation value is the largest concentration evaluation value in the concentration evaluation value set. The optimal ozone concentration is the ozone concentration corresponding to the optimal evaluation value.

[0046] It should be understood that the introduction of the optimal ozone concentration into the ozone generator to obtain the target ozone generator means introducing the optimal ozone concentration into the ozone concentration control system of the ozone generator so that the ozone generator produces gaseous ozone with the optimal ozone concentration. The target ozone generator is the ozone generator into which the optimal ozone concentration is introduced.

[0047] S4. Obtain the minimum ozone time and the maximum ozone time using the time detection sample set, the target ozone generator and the test box.

[0048] In detail, the method of obtaining the minimum ozone time and the maximum ozone time by using the time detection sample set, the target ozone generator and the test box includes: The time detection sample set includes q time detection samples, and the q time detection samples are classified into test modes to obtain j minimum detection samples and k maximum detection samples, where j+k=q; Extract m minimum test samples from j minimum test samples, perform ATP bioluminescence test on the m minimum test samples, and obtain m reference microbial contents, where m < j; The reference content mean is calculated using m reference microbial contents, wherein the reference content mean is the average value of the m reference microbial contents; Acquire the test time, extract a minimum test sample from the j minimum test samples, and place the extracted minimum test sample into the test box to obtain an intermediate test box; Start a target ozone generator for generating target ozone, use the started target ozone generator to deliver target ozone to the intermediate test box, take the time of starting the target ozone generator as the starting point and record the time in real time to obtain the waiting time, when the waiting time is equal to the test time, turn off the target ozone generator to obtain a first time test box, and use the first time test box to obtain a time test sample; The time test samples were subjected to ATP bioluminescence detection to obtain the test microbial content; Comparing the test microorganism content with the preset content threshold; If the test microorganism content is greater than the content threshold, the update time is calculated using the test time, the test microorganism content, the reference content mean and the content threshold, the update time is used as the test time, and the step of extracting a minimum test sample from the j minimum test samples is returned; If the tested microbial content is less than or equal to the content threshold, the test time is taken as the minimum ozone time; The following operations are performed on each of the k maximum detection samples: Place the largest test sample into the test box to obtain an advanced test box; The target ozone generator is started, and the target ozone generator after being started is used to deliver the target ozone to the advanced test box, so as to obtain a second time test box, and the time when the target ozone generator is started is used as the starting point and the time is recorded in real time to obtain the limit time; Using a pre-built colorimeter to detect the maximum detection sample in the second time test box to obtain the sample color difference, wherein the frequency of the colorimeter during detection is preset as the color difference detection frequency; Compare the sample color difference with the preset color difference threshold; When the sample color difference is greater than or equal to the color difference threshold, the limit time is used as the initial maximum time; The initial maximum times are summarized to obtain k initial maximum times, and the maximum ozone time is calculated using the k initial maximum times, wherein the maximum ozone time is an average value of the k initial maximum times.

[0049] It should be explained that the minimum detection sample is a time detection sample used to subsequently obtain the minimum ozone time, and the maximum detection sample is a time detection sample used to subsequently obtain the maximum ozone time.

[0050] It should be understood that the test mode classification of the q time detection samples means classifying the q time detection samples according to subsequent test purposes. For example, the subsequent time test requires 10 minimum detection samples and 10 maximum detection samples, so the 20 cucumber samples are divided into 10 minimum detection samples and 10 maximum detection samples, and the 10 minimum detection samples are used to subsequently obtain the minimum ozone time, and the 10 maximum detection samples are used to subsequently obtain the maximum ozone time.

[0051] It is understandable that ATP bioluminescence detection refers to detection using adenosine triphosphate bioluminescence method. The technology of performing ATP bioluminescence detection on m minimum detection samples and the technology of performing ATP bioluminescence detection on time test samples are both existing technologies and will not be repeated here.

[0052] It should be explained that the reference microbial content represents the content of surviving microorganisms on the minimum test sample. Target ozone refers to gaseous ozone with an optimal ozone concentration. Test time refers to the length of time the minimum test sample is treated with target ozone in the intermediate test box. Optionally, the test time is obtained by artificial setting, and the intermediate test box refers to the test box in which the minimum test sample is placed. The first time test box refers to the intermediate test box to which the target ozone is delivered. The time test sample is the minimum test sample after being treated with the target ozone.

[0053] Exemplarily, the minimum test sample is placed in an intermediate test box, the target ozone generator is started at 10:00 and the target ozone is delivered to the intermediate test box, and the test time is 10 minutes. Then at 10:10, the target ozone generator is turned off, the delivery of target ozone is stopped, and the minimum test sample treated with the target ozone is extracted from the first time test box and used as the time test sample.

[0054] It should be explained that the test microbial content represents the content of surviving microorganisms on the time test sample. The content threshold must refer to the GB29921-2021 National Food Safety Standard and is set by the processor. The main function of the update time is to update the test time. The minimum ozone time represents the shortest time when the target ozone is used to treat fresh-cut vegetables, which is used for subsequent adjustments to the target ozone time.

[0055] For example, if the minimum ozone time is 10 minutes, it means that the fresh-cut vegetables must be treated with the target ozone for at least 10 minutes to reduce the microbial content on the surface of the fresh-cut vegetables to below the content threshold, thereby facilitating the storage of the fresh-cut vegetables.

[0056] It should be explained that the advanced test box is a test box with the largest test sample placed in it. The limit time refers to the time when the target ozone generator is started as the starting point and the time is recorded in real time, and the recorded time is the end point, and the time value is obtained by subtracting the starting point from the end point.

[0057] In detail, the method of using a pre-built colorimeter to detect the maximum detection sample in the second time test box to obtain the sample color difference includes: Using a pre-built colorimeter and a preset color difference detection frequency to detect the maximum detection sample, a plurality of test parameter sets are obtained, wherein the test parameter sets include a test brightness, a test red-green value, and a test yellow-blue value; Using multiple test parameter sets to confirm an initial parameter set, wherein the initial parameter set is the first test parameter set obtained by the colorimeter based on the color difference detection frequency, and the initial parameter set includes: initial brightness, initial red and green values, and initial yellow and blue values; For each of the multiple test parameter sets, perform the following operations: The sample color difference is calculated using the test parameter set and the initial parameter set. The calculation formula is as follows: , in, is the sample color difference, , and are the initial brightness, initial red and green values, and initial yellow and blue values ​​in the initial parameter set, , and They are respectively the test brightness, test red-green values, and test yellow-blue values ​​in the test parameter set.

[0058] It should be understood that the technology of using a pre-built colorimeter and a preset color difference detection frequency to detect the maximum detection sample to obtain a test parameter set is a prior art and will not be described in detail here. The multiple test parameter sets are a collection of test parameter sets obtained by recording each time the maximum detection sample is detected.

[0059] It should be explained that a colorimeter is an instrument for testing color deviation. The color difference detection frequency is set by the processor. The test brightness, test red-green value, and test yellow-blue value are the brightness of the maximum test sample detected by the colorimeter, the red-green value of the sample color, and the yellow-blue value of the sample color. The initial brightness, initial red-green value, and initial yellow-blue value are the test brightness, test red-green value, and test yellow-blue value at the first test. The color difference threshold is related to the color of the maximum test sample and is set by the processor.

[0060] Exemplarily, the detection frequency is once per minute. The first detection is performed at 10:00 to obtain the initial parameter set. The second detection is performed at 10:01 to obtain the test parameter set. The sample color difference is calculated to be 0.3 using the test parameter set and the initial parameter set, which is less than the color difference threshold of 1.5. The third detection is performed at 10:02, and so on, until the test parameter set is obtained at 10:05. The sample color difference is calculated to be 1.6, which is greater than the color difference threshold. At this time, the limit time is 5 minutes, and 5 minutes is used as the initial maximum time.

[0061] It should be understood that while the target ozone generator is started, the colorimeter is used to detect the maximum detection sample in the advanced test box that is delivering the target ozone, wherein the advanced test box that is delivering the target ozone is the second time test box.

[0062] It should be explained that the maximum ozone time represents the longest time that the target ozone is used to treat fresh-cut vegetables, and is used for subsequent adjustments to the target ozone time.

[0063] For example, if the maximum ozone time is 30 minutes, it means that the vegetable sample is continuously treated with the target ozone for a maximum of 30 minutes. After 30 minutes, the fresh-cut vegetables will be oxidized and discolored due to excessive ozone treatment, which is not conducive to the storage of fresh-cut vegetables.

[0064] In detail, the calculation formula of the update time is as follows: , in, To update time, is the mean value of reference content, is the content threshold, To test the microbial content, It's time for testing.

[0065] S5. Obtain storage time, and calculate target ozone time using minimum ozone time, maximum ozone time, and storage time.

[0066] In detail, the calculation formula of the target ozone time is as follows: , in, is the target ozone time, For storage time, The preset storage limit time. is the maximum ozone time, is the minimum ozone time.

[0067] It should be explained that the storage time refers to the expected storage time of fresh-cut vegetables. For example, if the expected storage time of fresh-cut cucumbers is 6 hours, the storage time is 6 hours. The target ozone time is the ideal time for the subsequent ozone treatment of fresh-cut vegetables. The limit storage time is related to the type and nature of the fresh-cut vegetables and is set by the processor.

[0068] S6. Obtain a set of fresh-cut vegetables, place the set of fresh-cut vegetables in a constant temperature storage room, obtain a target storage room, take the time when the set of fresh-cut vegetables is placed in the constant temperature storage room as the starting point and record the time in real time to obtain the monitoring time.

[0069] It should be explained that the fresh-cut vegetable set is a plurality of fresh-cut vegetables to be stored, for example, a plurality of fresh-cut tomatoes to be stored is the fresh-cut vegetable set. The target storage room is a constant temperature storage room where the fresh-cut vegetable set is placed. The monitoring time is the time when the fresh-cut vegetable set is placed in the constant temperature storage room as the starting point and the time is recorded in real time, and the recorded time is the end point, and the time value is obtained by subtracting the starting point from the end point.

[0070] Exemplarily, at 10:00, the fresh-cut vegetables are put into the constant temperature storage room. When the time is 10:05, the monitoring time is 5 minutes, and when the time is 10:08, the monitoring time is 8 minutes.

[0071] S7, start the target ozone generator for generating target ozone, use the started target ozone generator to deliver the target ozone to the target storage chamber to obtain a reaction storage chamber, and use the time for the target ozone generator to deliver the target ozone to the target storage chamber as the reaction time. When the reaction time is equal to the target ozone time, turn off the target ozone generator, and use the gas exhauster to perform an exhaust operation on the reaction storage chamber to obtain a final storage chamber.

[0072] It should be explained that the reaction storage chamber is the target storage chamber to which the target ozone is delivered. The reaction time is the time when the target ozone generator delivers the target ozone to the target storage chamber as the starting point and the time is recorded in real time, and the recorded time is the end point, and the time value is obtained by subtracting the starting point from the end point.

[0073] In detail, the process of exhausting the reaction storage chamber by using a gas exhauster to obtain a final storage chamber includes: The gas discharger includes: a gas storage tank storing inert gas, a pressure reducing valve and a transmission pipeline, and the reaction storage chamber includes an exhaust fan, wherein the pressure reducing valve is located at the connection between the gas storage tank and the transmission pipeline, and the gas storage tank is connected to the reaction storage chamber through the transmission pipeline; Open the pressure reducing valve, take the time of opening the pressure reducing valve as the starting point and record the time in real time to obtain the exhaust time, use the transmission pipeline to perform gas interaction between the gas storage tank and the reaction storage chamber, wherein the storage gas pressure value of the gas storage tank and the storage gas pressure value of the reaction storage chamber are set, and the storage gas pressure value is greater than the storage gas pressure value, and when the exhaust time is equal to the preset cleaning time threshold, close the pressure reducing valve to obtain a mixed gas; Turning on the exhaust fan of the reaction storage chamber, and using the turned-on exhaust fan to exhaust the mixed gas in the reaction storage chamber to obtain a clean storage chamber; Use a pre-built ozone analyzer to monitor the clean storage room in real time to obtain the clean ozone concentration; Compare the clean ozone concentration with the preset safety concentration threshold; If the clean ozone concentration is greater than the safety concentration threshold, the clean storage chamber is used as a reaction storage chamber, and the process returns to the step of opening the pressure reducing valve; If the clean ozone concentration is less than or equal to the safety concentration threshold, the clean storage room will be used as the final storage room.

[0074] It should be explained that the exhaust time refers to the time when the pressure reducing valve is opened as the starting point and the time is recorded in real time, and the recorded time is used as the end point, and the time value is obtained by subtracting the starting point from the end point. The storage pressure value refers to the pressure value inside the gas storage tank, and the storage pressure value refers to the pressure value inside the reaction storage chamber. For example, when a high-pressure nitrogen tank is used as the gas storage tank, the pressure value inside the high-pressure nitrogen tank is obviously greater than the pressure value inside the reaction storage chamber under atmospheric pressure. The cleaning time threshold is set by the processor. Mixed gas refers to the gas inside the reaction storage chamber after gas interaction. Gas interaction refers to the process of gas exchange between the inert gas and the target ozone after the pressure reducing valve is opened.

[0075] It should be explained that an exhaust fan is installed in the constant temperature storage room corresponding to the reaction storage room, and the exhaust fan can realize the gas exchange between the indoor air in the reaction storage room and the external air. Since it is impossible for all the gas in the reaction storage room to be exhausted, it is optional to monitor the air pressure value of the mixed gas in the reaction storage room. When the air pressure value reaches a preset air pressure threshold, it is considered that the mixed gas in the reaction storage room is exhausted. The clean storage room refers to the reaction storage room after the mixed gas is exhausted.

[0076] It should be explained that the ozone analyzer is an instrument used to monitor the ozone concentration in the gas inside the clean storage room. The clean ozone concentration refers to the ozone concentration in the gas inside the clean storage room. The safe concentration threshold refers to the expected clean ozone concentration and is set by the processor. The final storage room refers to the clean storage room where the clean ozone concentration is less than or equal to the safe concentration threshold.

[0077] S8. Obtain the carbon dioxide concentration time series according to the preset gas monitoring frequency, carbon dioxide detector and final storage room, confirm the real-time carbon dioxide concentration and the nearby carbon dioxide concentration based on the carbon dioxide concentration time series, and calculate the reference breathing rate using the real-time carbon dioxide concentration and the nearby carbon dioxide concentration.

[0078] Exemplarily, the gas monitoring frequency is once every 10 minutes, and the gas in the final storage room is tested once every 10 minutes using a carbon dioxide detector. If the carbon dioxide concentrations detected for the first, second, and third times are 421ppm, 423ppm, and 424ppm, respectively, the carbon dioxide concentration time series is {421ppm, 423ppm, 424ppm}.

[0079] It should be explained that the carbon dioxide concentration time series is obtained by the carbon dioxide detector monitoring the final storage room according to the gas monitoring frequency, and the monitored carbon dioxide concentrations are sorted in order from the first to the last according to their corresponding time. Optionally, a Kornoi infrared carbon dioxide gas detector is used as a carbon dioxide detector. The real-time carbon dioxide concentration is the last carbon dioxide concentration in the carbon dioxide concentration time series, and the adjacent carbon dioxide concentration is the carbon dioxide concentration that is adjacent to the real-time carbon dioxide concentration in the carbon dioxide concentration time series and is located before the real-time carbon dioxide concentration.

[0080] In detail, the calculation formula of the reference respiratory rate is as follows: , in, is the reference respiratory rate, is the real-time carbon dioxide concentration, To approximate the carbon dioxide concentration, For the quality of fresh cut vegetables set, It is the preset monitoring interval.

[0081] It should be explained that the quality of the fresh-cut vegetable set is obtained by weighing the fresh-cut vegetable set in advance. The monitoring interval is set by the processor. The reference respiration rate reflects the respiration rate of the fresh-cut vegetables in the fresh-cut vegetable set. The higher the reference respiration rate, the higher the respiration rate of the fresh-cut vegetables.

[0082] S9. Compare the reference breathing rate with the preset breathing rate threshold. If the reference breathing rate is greater than or equal to the breathing rate threshold, the final storage room is used as the target storage room, and the process returns to the step of using the started target ozone generator to deliver target ozone to the target storage room until the monitoring time is equal to the storage time, thereby completing the storage of fresh-cut vegetables.

[0083] It should be explained that the respiration rate threshold is related to the type and properties of fresh-cut vegetables and is set by the processor.

[0084] It should be understood that since the reference respiration rate reflects the respiration rate of the fresh-cut vegetables in the fresh-cut vegetable set, when the reference respiration rate is greater than the respiration rate threshold, it means that the respiration of the fresh-cut vegetables is too strong, which is not conducive to the storage of fresh-cut vegetables. In this case, the process returns to the step of using the started target ozone generator to deliver the target ozone to the target storage chamber, and re-applies the target ozone to suppress the respiration of the fresh-cut vegetables.

[0085] The present invention is to solve the problems described in the background technology. The present invention starts a pre-constructed ozone adjustment system, wherein the ozone adjustment system includes an ozone generator, a constant temperature storage chamber, a test box, a gas exhauster and a carbon dioxide detector. It can be seen that the embodiment of the present invention adopts an ozone adjustment system that integrates multiple devices, which improves the automation and systematization of storing fresh-cut vegetables, and then obtains a vegetable sample set, wherein the vegetable sample set includes multiple vegetable samples, and the multiple vegetable samples are classified by test mode to obtain a concentration detection sample set and a time detection sample set. It can be seen that the embodiment of the present invention classifies the vegetable sample set, which facilitates the subsequent testing of the ozone treatment concentration and the ozone treatment time, respectively, and uses the concentration detection sample set, the ozone generator and the test box to obtain Take the optimal ozone concentration, introduce the optimal ozone concentration into the ozone generator, and obtain the target ozone generator. It can be seen that the embodiment of the present invention calculates the optimal ozone concentration suitable for fresh-cut vegetables by testing the concentration detection sample set, provides data support for the subsequent storage of fresh-cut vegetables, and improves the preservation effect of fresh-cut vegetables when storing. The minimum ozone time and the maximum ozone time are obtained by using the time detection sample set, the target ozone generator and the test box. It can be seen that the embodiment of the present invention determines the appropriate time range for ozone treatment by testing the time detection sample set, which can not only ensure the freshness of fresh-cut vegetables, but also avoid excessive treatment and reduce the damage rate of fresh-cut vegetables. The storage time is obtained, and the target ozone time is calculated using the minimum ozone time, the maximum ozone time and the storage time. It can be seen that the embodiment of the present invention further adjusts the target ozone time according to the storage time of fresh-cut vegetables, thereby improving the accuracy of ozone treatment on fresh-cut vegetables, and further improving the preservation effect of fresh-cut vegetables when storing, obtaining a set of fresh-cut vegetables, placing the set of fresh-cut vegetables in a constant temperature storage chamber, obtaining a target storage chamber, taking the time when the set of fresh-cut vegetables is placed in the constant temperature storage chamber as the starting point and recording the time in real time to obtain the monitoring time. It can be seen that the embodiment of the present invention obtains the monitoring time by recording the storage time of the fresh-cut vegetables in real time, which is convenient for subsequent judgment of whether the storage of the fresh-cut vegetables is completed according to the monitoring time and the storage time, thereby improving the degree of automation, starting the target ozone generator for generating target ozone, and using the started target ozone generator to transport the target ozone to the target storage chamber. ozone, obtain a reaction storage chamber, take the time for the target ozone generator to deliver the target ozone to the target storage chamber as the reaction time, when the reaction time is equal to the target ozone time, turn off the target ozone generator, and use the gas exhauster to perform the exhaust operation on the reaction storage chamber to obtain the final storage chamber. It can be seen that the embodiment of the present invention improves the preservation effect of fresh-cut vegetables when storing them by accurately controlling the ozone concentration and processing time when treating fresh-cut vegetables, and reduces the damage rate of fresh-cut vegetables. The carbon dioxide concentration time series is obtained according to the preset gas monitoring frequency, the carbon dioxide detector and the final storage chamber, and the real-time carbon dioxide concentration and the adjacent carbon dioxide concentration are confirmed based on the carbon dioxide concentration time series. The reference respiratory rate is calculated using the real-time carbon dioxide concentration and the adjacent carbon dioxide concentration.Compare the reference breathing rate with the preset breathing rate threshold. If the reference breathing rate is greater than or equal to the breathing rate threshold, the final storage room is used as the target storage room, and the step of using the activated target ozone generator to deliver the target ozone to the target storage room is returned until the monitoring time is equal to the storage time, and the storage of fresh-cut vegetables is completed. It can be seen that the embodiment of the present invention monitors the breathing rate of fresh-cut vegetables during storage in real time, understands the fresh-keeping state of the vegetables in real time, and thus determines whether it is necessary to ozone the fresh-cut vegetables again, thereby improving the fresh-keeping effect when storing fresh-cut vegetables. Therefore, the present invention can improve the fresh-keeping effect when storing fresh-cut vegetables and reduce the damage rate of fresh-cut vegetables.

[0086] like Figure 2 , which is a functional module diagram of a fresh-cut vegetable storage device based on gaseous ozone treatment provided by one embodiment of the present invention.

[0087] The fresh-cut vegetable storage device 100 based on gaseous ozone treatment of the present invention can be installed in an electronic device 1. According to the functions to be implemented, the fresh-cut vegetable storage device 100 based on gaseous ozone treatment can include a detection sample acquisition module 101, an ozone parameter setting module 102, a gaseous ozone treatment module 103 and a respiratory rate monitoring module 104.

[0088] The detection sample acquisition module 101 is used to start a pre-built ozone conditioning system, wherein the ozone conditioning system includes an ozone generator, a constant temperature storage chamber, a test box, a gas exhauster and a carbon dioxide detector, to obtain a vegetable sample set, wherein the vegetable sample set includes a plurality of vegetable samples, and the plurality of vegetable samples are classified into test modes to obtain a concentration detection sample set and a time detection sample set; The ozone parameter setting module 102 is used to obtain the optimal ozone concentration using the concentration detection sample set, the ozone generator and the test box, import the optimal ozone concentration into the ozone generator to obtain the target ozone generator, use the time detection sample set, the target ozone generator and the test box to obtain the minimum ozone time and the maximum ozone time, obtain the storage time, and calculate the target ozone time using the minimum ozone time, the maximum ozone time and the storage time; The gaseous ozone treatment module 103 is used to obtain a set of fresh-cut vegetables, place the set of fresh-cut vegetables in a constant temperature storage chamber, obtain a target storage chamber, take the time when the set of fresh-cut vegetables is placed in the constant temperature storage chamber as the starting point and record the time in real time to obtain a monitoring time, start a target ozone generator for generating target ozone, use the started target ozone generator to deliver target ozone to the target storage chamber, obtain a reaction storage chamber, take the time when the target ozone generator delivers the target ozone to the target storage chamber as the reaction time, and when the reaction time is equal to the target ozone time, turn off the target ozone generator, and use the gas exhauster to perform an exhaust operation on the reaction storage chamber to obtain a final storage chamber; The breathing rate monitoring module 104 is used to obtain the carbon dioxide concentration time series according to the preset gas monitoring frequency, the carbon dioxide detector and the final storage room, confirm the real-time carbon dioxide concentration and the nearby carbon dioxide concentration based on the carbon dioxide concentration time series, calculate the reference breathing rate using the real-time carbon dioxide concentration and the nearby carbon dioxide concentration, compare the reference breathing rate with the preset breathing rate threshold, if the reference breathing rate is greater than or equal to the breathing rate threshold, then the final storage room is used as the target storage room, and return to the step of using the started target ozone generator to deliver the target ozone to the target storage room until the monitoring time is equal to the storage time, and the storage of fresh-cut vegetables is completed.

[0089] In detail, each module in the fresh-cut vegetable storage device 100 based on gaseous ozone treatment in the embodiment of the present invention is used in the same manner as described above. Figure 1 The fresh-cut vegetable storage method based on gaseous ozone treatment described in the invention has the same technical means and can produce the same technical effects, so it will not be repeated here.

[0096] For example, although not shown, the electronic device 1 may also include a power source (such as a battery) for supplying power to various components.

[0099] The fresh-cut vegetable storage method program based on gaseous ozone treatment stored in the memory 11 of the electronic device 1 is a combination of multiple instructions. When running in the processor 10, it can achieve: Start the pre-built ozone conditioning system, wherein the ozone conditioning system includes an ozone generator, a constant temperature storage room, a test chamber, a gas exhauster and a carbon dioxide detector; Obtaining a vegetable sample set, wherein the vegetable sample set includes a plurality of vegetable samples, classifying the plurality of vegetable samples by test mode, and obtaining a concentration detection sample set and a time detection sample set; The optimal ozone concentration is obtained by using the concentration detection sample set, the ozone generator and the test box, and the optimal ozone concentration is introduced into the ozone generator to obtain the target ozone generator; The minimum ozone time and the maximum ozone time are obtained using the time detection sample set, the target ozone generator and the test chamber; Obtain storage time, and calculate target ozone time using minimum ozone time, maximum ozone time and storage time; Acquire a set of fresh-cut vegetables, place the set of fresh-cut vegetables in a constant temperature storage room, obtain a target storage room, take the time when the set of fresh-cut vegetables is placed in the constant temperature storage room as a starting point and record the time in real time to obtain a monitoring time; Starting a target ozone generator for generating target ozone, using the started target ozone generator to deliver target ozone to a target storage chamber to obtain a reaction storage chamber, taking the time for the target ozone generator to deliver target ozone to the target storage chamber as the reaction time, and when the reaction time is equal to the target ozone time, turning off the target ozone generator, and using a gas exhauster to perform an exhaust operation on the reaction storage chamber to obtain a final storage chamber; Obtain the carbon dioxide concentration time series according to the preset gas monitoring frequency, carbon dioxide detector and final storage room, confirm the real-time carbon dioxide concentration and the near carbon dioxide concentration based on the carbon dioxide concentration time series, and calculate the reference breathing rate using the real-time carbon dioxide concentration and the near carbon dioxide concentration; Compare the reference breathing rate with the preset breathing rate threshold. If the reference breathing rate is greater than or equal to the breathing rate threshold, the final storage room is used as the target storage room, and the process returns to the step of using the started target ozone generator to deliver the target ozone to the target storage room until the monitoring time is equal to the storage time, thereby completing the storage of fresh-cut vegetables.
