[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0026] Figure 1 It is a schematic diagram of the process of the sweet substance compounding method provided by the present invention.

[0027] The following will be combined Figure 1 The method for compounding sweet substances is described.

[0028] In an exemplary embodiment of the present invention, Figure 1 It can be seen that the sweetening substance compounding method may include steps 110 to 130, and each step will be introduced below.

[0029] In step 110, initial sweetening curves of different sweet substances are obtained.

[0030] In one embodiment, the sweetener can be understood as a substance used to replace sucrose. Since long-term use of sucrose can affect the health of users, in order to ensure the health of users and find a combination of sweeteners that can replace the taste of sucrose, the sweeteners can be compounded. The closer the taste of the sweetener combination is to sucrose, the better the compounding effect.

[0031] Among them, the initial sweetness curve is used to characterize the sweetness intensity change trend of sweet substances in the time dimension. In other words, the initial sweetness curve is not an accurate sweetness intensity-time curve.

[0032] In another exemplary embodiment of the present invention, the initial sweetening curve can be obtained in the following manner:

[0033] Obtaining multiple groups of instant sweetness intensity values ​​of sweet substances at different times;

[0034] Based on multiple sets of instant sweetness intensity values ​​and corresponding moments, an initial sweetness release curve of the sweet substance is constructed.

[0035] In this embodiment, the instant sweetness intensity values ​​at different moments can be used to outline the sweetness intensity change trend of different sweet substances in the time dimension, thereby laying a foundation for distinguishing different types of sweet substances (including the first sweet substance and the second sweet substance).

[0036] In step 120 , a plurality of sweeteners are divided into a first sweetener group and a second sweetener group based on the initial sweetness release curve.

[0037] In one embodiment, multiple sweeteners can be divided into a first sweetener group and a second sweetener group according to the initial sweetness release curve. Figure 4 and Figure 5 To explain, Figure 4 The acesulfame potassium shown in can be considered as the first sweet substance, Figure 5 The steviol glycosides shown can be considered as the second sweetener. Figure 4 In the figure, the light color curve corresponds to the initial sweetening curve of acesulfame potassium. Figure 5 In the figure, the light color curve corresponds to the initial sweetening curve of stevioside.

[0038] It can be understood that the first sweet substance in the first sweet substance group has an earlier sweetness release than sucrose, and a shorter sweet aftertaste than sucrose, that is, the first initial sweetness release curve of the first sweet substance reaches a peak value of sweetness intensity at a smaller peak time than the sucrose sweetness release curve of sucrose at a smaller peak time, and the sweetness duration of the first initial sweetness release curve is smaller than the sweetness duration of the sucrose sweetness release curve. The sweetness duration refers to the total duration of sweetness.

[0039] The second taste substance in the second sweet substance group has a later sweetness release than sucrose, and a longer aftertaste than sucrose, that is, the second initial sweetness release curve of the second sweet substance reaches a peak value when the peak moment corresponding to the peak value of the sweetness intensity is greater than the peak moment corresponding to the peak value of the sucrose sweetness release curve of sucrose, and the sweetness duration of the second initial sweetness release curve is greater than the sweetness duration of the sucrose sweetness release curve.

[0040] In step 130, compounding is performed based on the first sweetener group and the second sweetener group to obtain a sweetener combination, so that the difference between the sweetening effect produced by the sweetener combination and the sweetening effect produced by sucrose is less than or equal to a sweetness intensity threshold, wherein the sweetener combination includes at least one first sweetener and at least one second sweetener.

[0041] In one embodiment, a sweet substance combination can be obtained by compounding the first sweet substance group and the second sweet substance group, so that the sweet effect produced by the sweet substance combination is the same or similar to the sweet effect produced by sucrose. The difference between the sweet effect produced by the sweet substance combination and the sweet effect produced by sucrose is less than or equal to the sweetness intensity threshold, indicating that the sweet effects of the two are the same or similar.

[0042] The sweetness intensity threshold may be adjusted according to actual conditions. In one example, the sweetness intensity threshold may be zero or as close to zero as possible.

[0043] By determining the sweet substance combination through the aforementioned embodiment, the efficiency of compounding the sweet substances can be improved, ensuring that a sweet substance combination with a taste closer to sucrose can be obtained through automatic compounding of the sweet substances.

[0044] The method for compounding sweet substances provided by the present invention obtains initial sweetness release curves of different sweet substances; based on the initial sweetness release curves, multiple sweet substances are divided into a first sweet substance group and a second sweet substance group; compounding is performed based on the first sweet substance group and the second sweet substance group to obtain a sweet substance combination, so that the difference between the sweetness effect produced by the sweet substance combination and the sweetness effect produced by sucrose is less than or equal to a sweetness intensity threshold, wherein the sweet substance combination includes at least one first sweet substance and at least one second sweet substance, thereby improving the efficiency of compounding sweet substances and ensuring that a sweet substance combination with a taste closer to sucrose can be obtained by automatically compounding sweet substances.

[0045] Figure 2 It is a schematic diagram of a process for obtaining a sweet substance combination by compounding a first sweet substance group and a second sweet substance group provided by the present invention.

[0046] The following will be combined Figure 2 The process of obtaining a sweet substance combination by compounding the first sweet substance group and the second sweet substance group is described.

[0047] In an exemplary embodiment of the present invention, Figure 2 It can be seen that the compounding process based on the first sweet substance group and the second sweet substance group to obtain the sweet substance combination may include steps 210 to 260, and each step will be introduced below.

[0048] In step 210, the first initial sweetness release curve of each first sweetness substance in the first sweetness substance group and the second initial sweetness release curve of each second sweetness substance in the second sweetness substance group are obtained.

[0049] In step 220, a first target sweetening function is obtained based on the first initial sweetening curve.

[0050] The first target sweetness function represents the sweetness intensity of the first sweet substance at different times.

[0051] In an exemplary embodiment of the present invention, based on the first initial sweetening curve, a first target sweetening function is obtained, which can be implemented in the following manner:

[0052] Based on the first initial sweetness release curve, a plurality of first measurement points are determined in the first initial sweetness release curve, wherein the first measurement point includes at least a first starting coordinate, a first ascending coordinate, a first extreme value coordinate, a first descending coordinate, and a first ending coordinate on the first initial sweetness release curve, wherein the first starting coordinate is a coordinate corresponding to a starting moment on the first initial sweetness release curve; the first ascending coordinate is a coordinate on the first initial sweetness release curve on a side where the slope is greater than 0; the first extreme value coordinate is a coordinate corresponding to a peak value of sweetness intensity on the first initial sweetness release curve; the first descending coordinate is a coordinate on the first initial sweetness release curve on a side where the slope is less than 0; and the first ending coordinate is a coordinate corresponding to an ending moment on the first initial sweetness release curve;

[0053] The plurality of discrete first measurement points are made continuous through spline interpolation to obtain a first target output function.

[0054] It should be noted that the first initial sweetening curve is a curve used to characterize the sweetness intensity change trend of the first sweet substance, and cannot accurately characterize the sweetness intensity of the first sweet substance at different times. In order to solve this problem, multiple first measurement points can be determined in the first initial sweetening curve, and the discrete first measurement points can be continuous using piecewise spline interpolation, and the first target sweetening function can be obtained using natural boundary parts, so as to ensure that the curve corresponding to the obtained first target sweetening function is smooth and has no oscillation, so that the sweet substances can be compounded more accurately.

[0055] In one embodiment, five first measurement points are taken. Let the coordinates of the five points be (x1, y1) to (x5, y5) respectively. Let the corresponding four curves be S1 to S4, where Si is defined between (xi, yi) and (xi+1, yi+1), and satisfy the conditions that the function values ​​of two adjacent curves at the intersection are equal, and the first-order and second-order derivatives are equal. The natural boundary condition means that the second-order derivative at (x1, y1) and (x5, y5) is equal to 0. It can be understood that the natural boundary condition corresponds to the first starting coordinate and the first ending coordinate. During the application process, the five first measurement points are subjected to spline interpolation processing to obtain the first target sweetening function. Through this embodiment, it can be ensured that the curve corresponding to the first target sweetening function is smooth and has no oscillation, so that the sweetening substances can be compounded more accurately.

[0056] In step 230, a second target sweetening function is obtained based on the second initial sweetening curve.

[0057] The second target sweetness function represents the sweetness intensity of the second sweet substance at different times.

[0058] In an exemplary embodiment of the present invention, based on the second initial sweetening curve, obtaining the second target sweetening function can be achieved in the following manner:

[0059] Based on the second initial sweetness curve, a plurality of second measurement points are determined in the second initial sweetness curve, wherein the second measurement points at least include a second starting coordinate, a second ascending coordinate, a second extreme value coordinate, a second descending coordinate, and a second ending coordinate on the second initial sweetness curve, wherein the second starting coordinate is a coordinate corresponding to a starting moment on the second initial sweetness curve; the second ascending coordinate is a coordinate on the second initial sweetness curve on a side where the slope is greater than 0; the second extreme value coordinate is a coordinate corresponding to a peak value of sweetness intensity on the second initial sweetness curve; the second descending coordinate is a coordinate on the second initial sweetness curve on a side where the slope is less than 0; and the second ending coordinate is a coordinate corresponding to an ending moment on the second initial sweetness curve;

[0060] The plurality of discrete second measurement points are made continuous through spline interpolation to obtain a second target output function.

[0061] It should be noted that the implementation principle of the second target sweetening function is the same as the implementation principle of the first target sweetening function, which will not be repeated in this embodiment.

[0062] In step 240 , a sweetening substance combination sweetening function of the sweetening substance combination is determined based on each of the first target sweetening functions and each of the second target sweetening functions.

[0063] In step 250, a target function is constructed based on the difference between the sweetness release function of the sweet substance combination and the sweetness release curve of sucrose.

[0064] In step 260 , based on the objective function, a first content value of each first sweetener and a second content value of each second sweetener in the sweetener combination are obtained.

[0065] The taste response of different sweet substances when mixed at low concentrations is linearly superimposed. Therefore, the sweetness function of the sweet substance combination can be determined based on the linear superposition of each first target sweetness function and each second target sweetness function.

[0066] Furthermore, based on the difference between the sweetening function of the sweetener combination and the sweetening curve of sucrose, an objective function is constructed, and based on the objective function, the first content value of each first sweetener in the sweetener combination and the second content value of each second sweetener are obtained. In other words, if the sweetener combination does not limit the number of each type of substance (corresponding to the first sweetener and the second sweetener), it can be A1+B1 or A1+A2+B1 or A1+B1+B2, etc. Among them, A1, A2...An represent different first sweeteners, and B1, B2...Bn represent different second sweeteners.

[0067] Figure 3It is a flow chart of obtaining the first content value of each first sweet substance in the sweet substance combination and the second content value of each second sweet substance based on the objective function provided by the present invention.

[0068] The following will be combined Figure 3 The process of obtaining the first content value of each first sweetener and the second content value of each second sweetener in the sweetener combination based on the objective function is described.

[0069] In an exemplary embodiment of the present invention, Figure 3 It can be seen that, based on the objective function, obtaining the first content value of each first sweetener and the second content value of each second sweetener in the sweetener combination may include steps 310 to 330, and each step will be introduced below.

[0070] In step 310, the first content value is used as a weight value of a first target sweetening function, and the second content value is used as a weight value of a second target sweetening function.

[0071] In step 320, based on the first target sweetening function and its corresponding weight value, and the second target sweetening function and its corresponding weight value, a sweetening function of the sweetening substance combination is determined.

[0072] In step 330 , under the constraint that both the first content value and the second content value are non-negative numbers, the first content value and the second content value are determined respectively to minimize the function value of the objective function.

[0073] The L2 norm can be used to measure the distance between two functions, thereby measuring the difference between different functions.

[0074] In one embodiment, the first content value to be calculated can be used as the weight value of the first target sweetening function, and the second content value to be calculated can be used as the weight value of the second target sweetening function. Based on the first target sweetening function and its corresponding weight value, and the second target sweetening function and its corresponding weight value, the sweetening function of the sweetening substance combination is determined.

[0075] In one embodiment, the sweetening function of the sweetening substance combination can be implemented using the following formula (1):

[0076] G=k1. g1+k2. g2+……k n . g n +m1. n1+m2. n2+……m n . n n (1)

[0077] Where G represents the sweetness function of the sweetness combination of the sweetness substances; k1...kn Indicates the weight value corresponding to the first target sweet function; g1…g n Indicates different first target sweetening functions; n1...n n Indicates the weight value corresponding to the second target sweet function; m1…m n Represents different second objective output functions.

[0078] Furthermore, the objective function can be expressed as formula (2):

[0079] M=GF (2)

[0080] Wherein, M represents the objective function; F represents the sucrose sweetening curve.

[0081] In another embodiment, the first content value and the second content value may be determined respectively under the constraint that both the first content value and the second content value are non-negative numbers, so as to minimize the function value of the objective function, wherein the minimum function value of the objective function may be expressed by formula (3):

[0082] min|k1.g1+k2.g2+……k n .g n +m1.n1+m2.n2+……m n .m n -F|

[0083] Among them, k1...k n ≥0; n1……n n ≥0.

[0084] The aforementioned solution of the first content value and the second content value is a quadratic programming, and any feasible method can be used to solve it. In one example, the fmincon function of matlab can be used to automatically call the sequential quadratic programming (SQP algorithm) to solve it. It can also be solved using the gradient descent method, simulated annealing algorithm, etc. In this embodiment, the method for solving the first content value and the second content value is not specifically limited.

[0085] It can be understood that the sweetener combination finally obtained includes first sweeteners having corresponding first content values ​​and second sweeteners having corresponding second content values.

[0086] According to the above description, the sweet substance compounding method provided by the present invention obtains the initial sweetness release curves of different sweet substances; based on the initial sweetness release curves, multiple sweet substances are divided into a first sweet substance group and a second sweet substance group; compounding is performed based on the first sweet substance group and the second sweet substance group to obtain a sweet substance combination, so that the difference between the sweetness effect produced by the sweet substance combination and the sweetness effect produced by sucrose is less than or equal to a sweetness intensity threshold, wherein the sweet substance combination includes at least one first sweet substance and at least one second sweet substance, thereby improving the efficiency of sweet substance compounding and ensuring that a sweet substance combination with a taste closer to sucrose can be obtained by automatically compounding the sweet substances.

[0087] Based on the same concept, the present invention also provides a sweet substance compounding device.

[0088] The sweet substance compounding device provided by the present invention is described below. The sweet substance compounding device described below and the sweet substance compounding method described above can be referred to each other.
