Description

[0002] In the tobacco industry, the aging process of tobacco strips is a crucial link, which directly affects the final quality and taste of tobacco products. Aging refers to a series of complex reactions of the chemical components in tobacco through natural or artificially controlled environmental conditions, so as to achieve the purpose of improving the aroma of tobacco, reducing impurities, and increasing the mellowness of the taste. This process usually takes months or even years and is affected by many factors, such as temperature, humidity, oxygen content, and the chemical composition of the tobacco itself. At the same time, if the aging time of tobacco strips is too long, it will bring about adverse effects such as reduced aroma, increased impurities, and worse taste.

[0003] Traditionally, the method of evaluating the aging state of tobacco leaves mainly relies on sensory evaluation, that is, experienced smokers judge the sensory qualities of tobacco such as aroma and taste by tasting. However, this method has the disadvantages of strong subjectivity, low efficiency, and difficulty in quantification, which makes it difficult to meet the needs of the modern tobacco industry for quality control and standardized production.

[0004] With the continuous advancement of detection technology and the widespread application of data analysis methods, people have begun to try to indirectly evaluate the aging state of tobacco strips by detecting various physical and chemical indicators during the aging process. By using the near-infrared model, tobacco strip samples can be quickly tested to obtain 55 groups of data including conventional chemical composition, pH, starch, polyphenols, amino acids, Amadori, and neophytadiene.

[0030] Embodiment 1

[0031] Figure 1 This is a flow chart of a method for predicting the aging state of tobacco strips provided in the first embodiment of the present invention. This embodiment is applicable to the case of predicting the aging state of tobacco strips in stock. The method can be executed by a device for predicting the aging state of tobacco strips. The device can be implemented in the form of hardware and / or software. The device can be configured in electronic devices such as computers and servers. Figure 1 As shown, the method includes:

[0032] S110, obtaining the test data of each grade of tobacco leaves and the sensory quality score corresponding to the test data, and converting the sensory quality score into a target sensory quality score; the test data includes the index data of each test index at different time periods; the target sensory quality score is used to judge the aging state of the tobacco leaves.

[0033] Among them, different production area types include different grades of tobacco leaves. For example, the production area type is Southwest Fragrance type, which includes Sichuan Huili, Yunnan Pu'er, Yunnan Honghe and other different grades of tobacco leaves.

[0034] In this embodiment, the tobacco strip samples of each grade of tobacco strips sampled at different time periods are tested by a near infrared model to obtain the test data of each grade of tobacco strips, and the sensory quality score of the tobacco strips corresponding to the test data is recorded. Among them, the test indicators of the test data include pH, polyphenols, amino acids, Amadori compounds, neophytadiene, etc. Specifically, polyphenols include chlorogenic acid, cryptochlorogenic acid, rutin, etc., amino acids include serine, glutamine, glycine, alanine, etc., and Amadori compounds include Glu-An, Fru-Amb, Fru-His, Fru-Val, etc.

[0035] Among them, the sensory quality score is determined by scoring by professional sensory evaluation experts according to specific standards. For example, in some evaluation methods, aroma quality and aroma quantity may each account for 15 points, impurities, concentration, strength, irritation, aftertaste may each account for 10 points, and combustibility and gray may each account for 10 points. The evaluation experts will evaluate the tobacco slices one by one according to these standards and give corresponding scores. Then, these scores will be added up to obtain a comprehensive score, which can be used to measure the sensory quality of the tobacco slices. In this embodiment, the sensory quality score can be converted to obtain a target sensory quality score. Among them, the target sensory quality score is used to judge the alcoholization state of the tobacco slice. Specifically, the sensory quality score of the tobacco slice at the critical value of excessive alcoholization can be assigned to N or N.5 points. When the sensory quality score of a certain grade of tobacco is just at the critical value of over-alcoholization when sampling for n times, it is assigned a value of N; when the sensory quality score of the tobacco of this grade is at the critical value of over-alcoholization when sampling for n times, but it has been over-alcoholized when sampling for n+1 times, the sensory quality score of the nth time is assigned a value of N.5. For example, N can be 60, so the sensory quality score of tobacco at the critical value of over-alcoholization can be assigned a value of 60 or 60.5 points.

[0036] The conversion formula for the sensory quality score of the non-over-alcoholization critical value of the tobacco slices is:

[0037] Y i =Y i ×Y n / Y′ n

[0038] Among them, Y i is the converted target sensory quality score, Y i is the raw sensory quality score, Y n is the target sensory quality score of the tobacco leaves after conversion at the critical value of over-alcoholization, that is, N; Y′ n It is the original sensory quality score of the tobacco slice at the critical value of over-alcoholization. It can be understood that the above formula is actually scaling the original sensory quality score to meet the score standards of N and N.5 assigned when it is at the critical value of over-alcoholization.

[0039] S120, screening the detection indicators based on the indicator data of each detection indicator of each grade of tobacco leaves at different time periods to obtain key indicators.

[0040] Since not all detection indicators have reference value for predicting the aging state of tobacco strips, it is necessary to screen the detection indicators. In this embodiment, the detection indicators are screened based on the indicator data of each detection indicator of each grade of tobacco strips at different time periods to obtain key indicators. Among them, the key indicators are indicators that have reference value for predicting the aging state of tobacco strips.

[0041] On the basis of the above embodiment, optionally, the detection indicators are screened based on the indicator data of each detection indicator of each grade of tobacco leaves at different time periods to obtain key indicators, including: for any detection indicator, an indicator change curve is generated based on the indicator data of the same grade of tobacco leaves at different time periods, and the indicator change curve changes with time; when the indicator change curves corresponding to the grades of tobacco leaves all meet the key indicator screening conditions, the detection indicator is determined as the key indicator.

[0042] In this embodiment, for any detection index, an index change curve is generated based on the index data of the same grade of tobacco leaves at different time periods, and the index change curve can characterize the change trend of the detection data of the detection index over time. Furthermore, the index change curves of each grade of tobacco leaves are judged based on the key indicator screening conditions. If the index change curves of each grade of tobacco leaves meet the key indicator screening conditions, the detection index is determined as the key indicator. Among them, the key indicator screening conditions can be that the index change curve shows a decreasing trend as a whole. Exemplarily, assuming that the detection index is chlorogenic acid, if the index change curves of the chlorogenic acid indicators of each grade of tobacco leaves show a decreasing trend as a whole, the chlorogenic acid indicator is the key indicator.

[0043] It should be noted that when the indicator change curve shows a trend of first increasing and then decreasing, since the indicator change curve as a whole still shows a decreasing trend, the indicator change curve still meets the key indicator screening conditions.

[0044] For example, the key indicators after screening are shown in Table 2:

[0045] Table 2

[0048]

[0049] S130, performing model fitting based on the indicator data of the key indicator and the target sensory quality score corresponding to the indicator data of the key indicator, and establishing a prediction model for the aging state of tobacco leaves.

[0050] In this embodiment, a model fitting is performed based on the linear relationship between the index data of the key index and the target sensory quality score corresponding to the index data of the key index to establish a prediction model for the aging state of tobacco slices.

[0051] On the basis of the above embodiment, optionally, the indicator data based on the key indicator and the target sensory quality score corresponding to the indicator data of the key indicator are used for model fitting to establish a tobacco leaf aging state prediction model, including: standardizing the indicator data of the key indicator to obtain standard indicator data; establishing a detection data matrix based on the standard indicator data; establishing a quality prediction matrix based on the target sensory quality score corresponding to the standard indicator data; and fitting a multivariate linear regression model based on the detection data matrix and the quality prediction matrix to obtain a tobacco leaf aging state prediction model.

[0052] Among them, standard indicator data refers to standardized indicator data after annotation processing. In this embodiment, the indicator data of key indicators are standardized to obtain standard indicator data; a detection data matrix is ​​established based on the standard indicator data; a quality prediction matrix is ​​established based on the target sensory quality score corresponding to the standard data; a multivariate linear regression model is fitted based on the detection data matrix and the quality prediction matrix to obtain a prediction model for the aging state of tobacco leaves. Among them, the standardization method can be Z-scor standardization method, range standardization method, proportion method, etc., which are not limited here.

[0053] On the basis of the above embodiment, optionally, the step of fitting a multiple linear regression model based on the detection data matrix and the quality prediction matrix to obtain a tobacco aging state prediction model comprises: using a preset regression analysis method to fit the multiple linear regression model based on the detection data matrix and the quality prediction matrix to obtain an unknown parameter matrix, wherein the unknown parameter matrix comprises unknown parameters in the multiple linear regression model; and determining the tobacco aging state prediction model based on the unknown parameter matrix and the multiple linear regression model.

[0054] The preset regression analysis method may be the least squares method. In this embodiment, the preset regression analysis method may be used to perform model fitting on the multiple linear regression model based on the detection data matrix and the quality prediction matrix, estimate the unknown parameters in the multiple linear regression model, and obtain an unknown parameter matrix; further, the unknown parameters in the unknown parameter matrix are substituted into the multiple linear regression model to obtain a prediction model for the aging state of tobacco leaves.

[0055] Specifically, the linear relationship of the multiple linear regression model is expressed as:

[0056] Y=Xβ+ε

[0057] Where Y is the quality prediction value matrix of number n, Y = (Y1, Y2, ..., Y n ) T ; β is the unknown parameter matrix of number m+1, β=(β1,β2,…,β m ) T ; ε is the error matrix of number n, ε=(ε1,ε2,…,ε n ) T , ε i ~N(0,σ 2 ); X is an n×(m+1) detection data matrix.

[0058] S140, acquiring detection data of the to-be-predicted tobacco strips in any time period, and determining the aging state of the to-be-predicted tobacco strips based on the detection data of the to-be-predicted tobacco strips in any time period and the tobacco strip aging state prediction model.

[0059] The to-be-predicted tobacco strip refers to the tobacco strip sample for which the tobacco strip aging state prediction is to be performed. In this embodiment, after the tobacco strip aging state prediction model is established, the detection data of the tobacco strip to be predicted in any period of time can be obtained, and the detection data of the period of time can be predicted based on the tobacco strip aging state prediction model to determine the aging state of the tobacco strip to be predicted. The aging state of the tobacco strip includes not over-aging, being at the over-aging critical value, and over-aging.

[0060] On the basis of the above embodiment, optionally, the aging state of the to-be-predicted tobacco strips is determined based on the detection data of the to-be-predicted tobacco strips in any time period and the tobacco strip aging state prediction model, comprising: standardizing the index data of key indicators in the detection data of the to-be-predicted tobacco strips in any time period to obtain the to-be-predicted index data; performing prediction based on the to-be-predicted index data and the tobacco strip aging state prediction model to obtain the target sensory quality score of the to-be-predicted tobacco strips; and determining the aging state of the to-be-predicted tobacco strips based on the target sensory quality score of the to-be-predicted tobacco strips.

[0061] The index data to be predicted refers to the index data of the key index in the detection data of the tobacco strips sampled at any time period after being standardized. In this embodiment, the index data of the key index in the detection data of the tobacco strips to be predicted at any time period is standardized to obtain the index data to be predicted at any time period; the index data to be predicted at any time period is substituted into the tobacco strip aging state prediction model for prediction to obtain the target sensory quality score of the tobacco strips to be predicted. The aging state of the tobacco strips to be predicted is determined based on the target sensory quality score of the tobacco strips to be predicted. It can be understood that during the aging process of the tobacco strips, as the aging process proceeds, the target sensory quality score of the tobacco strips will show a decreasing trend due to over-aging. Therefore, the target sensory quality score of the tobacco strips to be predicted is compared with the target sensory quality score of the over-aging critical value. If the target sensory quality score of the tobacco strips to be predicted is greater than the target sensory quality score of the over-aging critical value, the aging state of the tobacco strips to be predicted is not over-aging; if the target sensory quality score of the tobacco strips to be predicted is less than the target sensory quality score of the over-aging critical value, the aging state of the tobacco strips to be predicted is over-aging; if the target sensory quality score of the tobacco strips to be predicted is equal to the target sensory quality score of the over-aging critical value, the aging state of the tobacco strips to be predicted is at the over-aging critical value.

[0062] This embodiment predicts the target sensory quality score of the tobacco strips to be predicted by using the tobacco strip aging state prediction model, thereby determining the aging state of the tobacco strips to be predicted by the target sensory quality score, which can achieve prediction of the sensory quality of the tobacco strips while realizing the prediction of the aging state of the tobacco strips.

[0063] The technical solution of this embodiment is to obtain the test data of each grade of tobacco strips and the sensory quality score corresponding to the test data, and convert the sensory quality score into a target sensory quality score; the test data includes the index data of each test index at different time periods; the target sensory quality score is used to judge the mellowing state of tobacco strips; the test index is screened based on the index data of each test index at different time periods of each grade of tobacco strips to obtain key indicators; the model is fitted based on the index data of the key indicators and the target sensory quality score corresponding to the index data of the key indicators to establish a prediction model for the mellowing state of tobacco strips; the test data of the tobacco strips to be predicted at any time period is obtained, and the mellowing state of the tobacco strips to be predicted is determined based on the test data of the tobacco strips to be predicted at any time period and the prediction model for the mellowing state of tobacco strips. Accurate prediction of the mellowing state of tobacco strips is achieved.

[0064] On the basis of the above-mentioned embodiment, optionally, the method of standardization processing includes: for any of the key indicators, determining the initial indicator data of the key indicator; and standardizing the indicator data of the key indicator based on the initial indicator data.

[0065] Specifically, the standardized formula is:

[0066] x′ i =x in / x i0 ,

[0067] Among them, x i0 represents the initial indicator data of the i-th key indicator, that is, the detection data of the first sampling of the i-th key indicator; x in It is the detection data of the nth sampling of the i key indicator.
