Description

Technical Field

[0001] The present invention relates to the technical field of fruit and vegetable extract extraction, and more particularly to a fruit and vegetable extract extraction method combined with ultrasound enhancement. Background Art

[0002] During the extraction process of ingredients from high-sugar vegetables, sugars often form stable micellar complex structures with functional small molecules such as phenols, polyphenols, and organic acids, making it difficult for these target ingredients to be released into the solvent after cell rupture, directly reducing the extraction release rate. At the same time, the high-sugar system itself has high viscosity and strong interfacial tension, which easily induces continuous foaming during the ultrasonic-enhanced extraction process, forming a physical acoustic barrier, making it difficult for ultrasonic cavitation bubbles to penetrate deep into the tissue structure, significantly weakening the efficiency of cell wall rupture. With the combined effects of sugar-phenol aggregation, foam accumulation, and obstructed ultrasonic energy transmission during the extraction process, it is difficult to fully extract the target components and control their purity even with high-energy ultrasound. Therefore, the key to the current low extraction efficiency lies in the dual superposition of the molecular encapsulation effect and the cavitation barrier effect caused by sugars in high-sugar and vegetable systems, which seriously hinders the effective release and high-purity separation of functional ingredients by ultrasonic-enhanced extraction. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a method for extracting fruit and vegetable extracts combined with ultrasound enhancement, which solves the problems of low release efficiency and difficult purity control of functional components in the high-sugar system proposed in the above background technology due to the superposition of the encapsulation effect and the acoustic resistance barrier by constructing a multi-dimensional synergistic extraction process of sugar-phenol deconstruction path, cavitation energy penetration path and migration enrichment feedback path.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a method for extracting fruit and vegetable extracts combined with ultrasound enhancement, comprising: S1.

Establish the state variables in the whole extraction process as real-time feedback factors, and realize the linkage correction and closed-loop optimization of the whole extraction process through the linkage feedback of extraction effect, cavitation energy usage and migration offset efficiency.

[0005] In a preferred embodiment, in S1, the extracellular matrix and sugars in the original fruit and vegetable material form an encapsulating structural unit, and the structural compactness of the encapsulating structural unit is determined by combining charge density, spatial crosslinking degree and surface polarity to obtain a sugar-phenol binding state configuration diagram to guide pre-deconstruction extraction preparation; The binding energy change curve, structural displacement amplitude and interface potential change of each sugar-phenol binding site in the sugar-phenol binding state configuration diagram are recorded under the action of acid-base buffer, and the polarity response characteristic spectrum is output to support the establishment of the structural loosening mechanism; the polarity response characteristic spectrum is combined with the hydration index, hydroxyl distribution and molecular cross-linking rate to derive a debinding sensitive site map, which is used to identify the target area stimulated by the prior extraction.

The release rate of functional factors, regional viscosity coefficient, microenvironment conductivity and local polarity change amplitude in the release evolution channel are combined to form a structural release trend map to determine which molecular states reach the extraction threshold; When the release rate of the functional factor in the structural release trend graph reaches the extraction threshold, and the migration interfacial tension at the boundary of the structure is less than the extraction retardation critical tension, and the release duration is not less than the stable release time requirement, the functional factor is judged to have reached a stable free state and serves as the extraction target for subsequent cavitation-enhanced extraction.

[0007] In a preferred embodiment, in S2, a cavitation boundary input variable group is formed based on the tension gradient, local density, and flow shear characteristics of the liquid phase region where the extraction target is located, and an excitation energy spectrum is generated through a local acoustic loss response test to calibrate the cavitation extraction power; The cavitation excitation energy spectrum is combined with the foam generation rate, film duration, and surface wave dispersion characteristics to form a foam barrier identification map, which is used to determine the barrier distribution structure of acoustic energy in the extraction liquid; If the superposition value of the acoustic reflection index and wave resistance in the foam obstacle map is higher than the cavitation focus interference threshold, it will be mapped as an inaccessible area, and the energy consumption avoidance strategy will be used to formulate the acoustic focus relocation extraction distribution map; the energy consumption distribution map of the inaccessible area is combined with the residual sound intensity gradient to generate a frequency band hopping strategy table, and a jumping acoustic wave energy redistribution sequence from medium frequency to high frequency is constructed to optimize the energy transfer efficiency in the extraction channel.

If not, the ratio of the excitation time window to the channel geometric width is adjusted in real time based on the frequency holding time and acoustic transmission attenuation rate. The three-layer extraction channel structure meets the requirements of cavitation extraction excitation integrity. The sound propagation penetration rate, extraction yield per unit energy consumption, and stability coefficient of the excitation flux are used as control input parameters, which are fed back to the excitation configuration parameter adjustment process for synchronous calibration of subsequent excitation conditions and extraction path ratios.

[0009] In a preferred embodiment, in S3, the local concentration value, charge distribution response, shear acceleration and surrounding temperature difference field data of the successfully extracted and released target factor are combined to form a migration driving variable group, and a migration initiation tensor field is derived for migration trajectory determination to construct a directional migration mechanism; The tensor field is activated and combined with the spatial inertia, polar direction deviation rate and boundary potential difference of the target molecule to generate a multivariate migration path prediction map, which is used to divide the controllable migration zone and the deviation instability zone; if the re-adsorption fitting error in the deviation instability zone is greater than the critical threshold of the interface polarity perturbation, a disturbance response zone is constructed and shear flow random perturbation is injected to forcibly break up the aggregation trend and prevent the recombination and deposition of the extracted molecules.

The acoustic energy response deviation map is constructed by the frequency attenuation gradient, acoustic energy dissipation rate and propagation time delay in the acoustic wave propagation path under ultrasonic action. It is used to identify propagation areas with insufficient acoustic energy coupling and discontinuous structural response sections in the current extraction process.

[0012] In a preferred embodiment, S4 further includes: if the frequency offset degree in the path fluctuation characteristic factor exceeds the frequency domain stability threshold, or if the relative displacement of the cavitation focus is detected to exceed the allowable error band, initiating path backtracking logic and sending a frequency perturbation instruction and a conductance difference adjustment parameter to the sugar-phenol structure release process; After receiving parameter feedback during the sugar-phenol structure release process, the system performs proportional judgment based on the sugar-phenol dissociation rate, local structure adhesion resistance, and release path curvature changes, and adjusts the acid solution injection acceleration rate and rotation disturbance switching rhythm accordingly; If the energy transfer gradient deviation rate detected in the acoustic energy conduction area exceeds the cavitation stability boundary value, the current acoustic excitation frequency distribution table is replaced and the cavitation focus repositioning execution process is restarted to maintain the consistency of the extraction energy access; If the stability rate in the component migration trajectory is lower than the migration path control reference value and its distribution direction angle deviation exceeds the preset guidance area tolerance range, the current bias control vector is updated and the direction field correction parameter set is regenerated.

[0013] In a preferred embodiment, S4 further includes: if any of the structural release state change amplitude parameter in the sugar-phenol structure release path, the acoustic field frequency stability evaluation index in the cavitation excitation stage, or the component migration trajectory offset in the enrichment migration path triggers the dual-threshold response logic, then writing into the full-process parameter correction area to complete a new round of control parameter starting value overwriting and channel variable reconstruction operations; After the whole process is fed back, the control of the extraction flux of the target component, the synchronous linkage control of the structure release path and the control of the acoustic energy distribution path are achieved through closed-loop parameter adjustment, thus completing the directional extraction of high-sugar vegetables in the ultrasonic extraction process.

[0016] Through shear perturbation-driven and temperature difference-assisted migration mechanisms, the target components are guided to aggregate in a directional manner in the potential offset field, thereby enhancing the enrichment trend of the target factors and the non-target exclusion selectivity.

[0017] By constructing migration path maps and deposition response maps with multiple parameters, we can achieve partitioned adsorption control in the interface area and improve the spatial selectivity of component enrichment and interface extraction efficiency.

[0018] By combining the feedback factors of structural release offset, frequency stability and trajectory offset, process linkage backtracking and parameter adaptive reconstruction are realized, thus enhancing the stability of the extraction path throughout the entire process.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Refer to the instruction manual Figure 1-5 According to one embodiment of the present invention, a method for extracting fruit and vegetable extracts by combining ultrasound enhancement comprises: S1.

[0026] In S1, the extracellular matrix and sugars in the original fruit and vegetable materials form an encapsulating structural unit. The structural compactness of the encapsulating structural unit is determined by combining charge density, spatial cross-linking degree and surface polarity to obtain a sugar-phenol binding state configuration diagram to guide pre-deconstruction extraction preparation; The binding energy change curve, structural displacement amplitude and interface potential change of each sugar-phenol binding site in the sugar-phenol binding state configuration diagram are recorded under the action of acid-base buffer, and the polarity response characteristic spectrum is output to support the establishment of the structural loosening mechanism; the polarity response characteristic spectrum is combined with the hydration index, hydroxyl distribution and molecular cross-linking rate to derive a debinding sensitive site map, which is used to identify target areas that can be stimulated by prior extraction.

Based on the distribution relationship of each dimension in the vector diagram in the structure, the release evolution path of the target functional factor along different stress directions within the carbohydrate-wrapped structure is deduced, providing a deconstruction basis for subsequent targeted extraction. The release rate of functional factors, regional viscosity coefficient, microenvironment conductivity and local polarity change amplitude in the release evolution channel are combined to form a structural release trend map to determine which molecular states have reached the extractable threshold; When the release rate of the functional factor in the structural release trend graph reaches the extractable threshold, and the migration interfacial tension at the structural boundary is less than the extraction blocking critical tension, and the release duration is not less than the minimum stable release time requirement, the functional factor is judged to have reached a stable free state and serves as an extractable target for subsequent cavitation-enhanced extraction.

[0028] In S2, a cavitation boundary input variable group is formed based on the tension gradient, local density and flow shear characteristics of the liquid phase region where the extractable target is located. The excitation energy spectrum is generated through the local acoustic loss response test to calibrate the cavitation extraction power.

If not, the ratio of the excitation time window to the channel geometric width is adjusted in real time based on the frequency holding time and acoustic transmission attenuation rate. The three-layer extraction channel structure meets the requirements of cavitation extraction excitation integrity. The sound propagation penetration rate, extraction yield per unit energy consumption, and stability coefficient of the excitation flux are used as control input parameters, which are fed back to the excitation configuration parameter adjustment process for synchronous calibration of subsequent excitation conditions and extraction path ratios.

[0030] In S3, the local concentration value, charge distribution response, shear acceleration and surrounding temperature difference field data of the successfully extracted and released target factor are combined to form a migration driving variable group, and the migration initiation tensor field is derived for migration trajectory determination to construct a directional migration mechanism; The tensor field is activated and combined with the spatial inertia, polar direction deviation rate and boundary potential difference of the target molecule to generate a multivariate migration path prediction map, which is used to divide the controllable migration zone and the deviation instability zone; if the re-adsorption fitting error in the deviation instability zone is greater than the critical threshold of the interface polarity perturbation, a disturbance response zone is constructed and shear flow random perturbation is injected to forcibly break up the aggregation trend and prevent the recombination and deposition of the extracted molecules.

[0032] In S4, the extraction purity, single-cycle extraction flux, component spatial distribution width, and initial structure release efficiency corresponding to the final target component extraction path are summarized into a joint extraction performance dataset. The joint extraction performance dataset is used to construct the whole-process extraction path deviation identification matrix. A path fluctuation characteristic factor group is output based on the path deviation identification matrix and the acoustic energy response deviation map during the cavitation excitation process. The acoustic energy response deviation map is constructed by the frequency attenuation gradient, acoustic energy dissipation rate and propagation time delay in the acoustic wave propagation path under ultrasonic action. It is used to identify propagation areas with insufficient acoustic energy coupling and discontinuous structural response sections in the current extraction process.

[0035] The above scheme is further explained and four parts are established to further describe the scheme; Furthermore, in the formula structure involved in this solution, dimensionless terms can serve as proportionality or structural adjustment factors. When combined with quantities with units, they only serve to scale the values, without introducing new physical dimensions.

This combination of "dimensionless terms and units" can be understood as a composite structural expression commonly used in mathematical and physical modeling, conforming to the principle of dimensional consistency and having a clear physical basis for interpretation. Secondly, in the formula structure of this scheme, if multiple variables with different physical units are involved, including but not limited to time, mass, or energy variables, their joint appearance is to express the collaborative modeling relationship of multiple physical mechanisms.

[0039] For the overall description of the present invention: This invention addresses the core issue of "difficulty extracting target functional factors in high-sugar vegetable systems." By collaboratively constructing a multidimensional extraction pathway in stages, this method achieves in-depth control of the entire process, from deconstruction of the sugar-phenol binding structure, to cavitation energy transfer, to component enrichment, and finally feedback correction. This method begins with structural identification and deconstruction of the complex micelle structure between sugars and phenols, polyphenols, or organic acid functional factors in fruit and vegetable raw materials. This structure is considered the primary obstacle limiting the extraction release rate. Due to its highly stable binding configuration, strong spatial curling, and significant charge shielding, the functional factors cannot be effectively released after traditional cell wall breaking. To this end, a configurational map of the sugar-phenol binding state was first established, and a polarity response characteristic spectrum was formed based on multi-parameter characteristics such as binding energy change, polarity response, and potential drift. Furthermore, a debonding sensitive site map was derived through the hydration index and cross-linking ratio to identify regions in the structure that can be preferentially extracted and stimulated. After a joint threshold determination of the structural density, binding energy, and tension perturbation coefficient of the mapped region, two pathways, ionic strength excitation or rotational perturbation, were used to enter the structural loosening or forced deconstruction state, respectively. Based on this, a dynamic release factor vector map and a structural release trend map were constructed to extract target functional factors in a stable free state with extraction potential. To further improve the ultrasonic extraction efficiency of the target functional factor after it enters the liquid phase, the acoustic response parameters of its environment are modeled, including tension gradient, local density, and shear flow field characteristics. A cavitation boundary input variable group is constructed. After obtaining the excitation energy spectrum through acoustic consumption response experiments, the foam generation rate and membrane attenuation curve are linked to generate a foam obstacle identification map. If the reflection and wave resistance values in the spectrum are higher than the threshold, it is marked as an inaccessible area and an acoustic focus relocation map is constructed. A frequency band hopping strategy table is constructed in combination with the residual acoustic intensity gradient to form a three-dimensional progressive frequency-hopping acoustic wave excitation path. Under this structure, a three-segment cavitation extraction channel is constructed through shear viscosity, agglomeration factor density, and molecular dielectric response to achieve staged advancement of the structure's pre-cracking, energy transmission, and target release. At the same time, indicators such as the acoustic wave frequency holding time and energy maintenance period are dynamically monitored and adjusted to ensure the stability of the extraction flux. Energy consumption, yield, and flux are fed back into the excitation path parameters as synergistic variables to achieve joint calibration between the energy focusing structure and the extraction path. When the functional factor is released, the scheme uses it as an enrichment migration object, and builds a migration driving variable group based on local concentration, charge response, acceleration and thermal field disturbance to form a migration initiation tensor field; uses spatial inertia, polarity offset rate and potential difference as input to generate a migration path prediction map, and divides the system into a controllable migration zone and an unstable zone; for areas with severe re-adsorption, shear flow disturbance is introduced to break up the aggregation trend, and a directional migration control field is constructed; if the migration path within the field does not reach the flux lower limit, a reverse pressure difference driving mechanism is introduced by using staggered temperature difference to strengthen the centripetal displacement of the target component, and a deposition response structure diagram is established in the deposition end area based on density, polarity and adsorption risk to achieve the exclusion of non-target components and the stabilization of the main path; if the migration trajectory is complete, the purity meets the standard and the trend is stable, the extraction path transfer process is triggered to ensure the directional collection and separation of the target factor; Throughout the entire process, the scheme uses the key state variables of each structural path as feedback factors, including the amplitude of structural release state changes in the sugar-phenol structure release path, the acoustic field frequency stability evaluation index in the cavitation excitation stage, and the component migration trajectory offset in the enrichment migration path; by extracting purity, flux, spatial distribution and initial release efficiency, a joint performance data set is constructed to output a path deviation identification matrix; if characteristic fluctuations such as frequency drift, cavitation focus misalignment or trajectory offset occur, the corresponding path is traced back to perform parameter reconstruction, such as updating the acid hydrolysis liquid rate, rotational perturbation rhythm, frequency distribution table or bias vector, and finally forming a closed-loop regulation process to achieve parameter linkage and path coordination from structural release to extraction enrichment, ensuring long-term stable operation of the system and the achievement of high-purity extraction goals.
