Description

Technical Field

Background Technology

[0002] Cigarette formulation design refers to the composition of tobacco leaves in cigarette production and the weight percentage of each type. It is a crucial step in cigarette production, involving the selection and blending of different types, grades, and origins of tobacco leaves to achieve specific aromas, flavors, and styles. Cigarette formulation design not only affects cigarette quality but also influences cost control and production efficiency.

[0003] Traditional cigarette formulation methods are typically based entirely on sensory evaluation. The general process involves first evaluating the tobacco leaves to be used in the formulation to understand their quality characteristics. After gaining a preliminary sensory understanding, several formulations with different structures are drafted based on product design requirements, experience, and sensory knowledge. Small samples are then rolled, and the one that best meets the design requirements is selected for pilot testing. Next, sensory evaluation is conducted, modifications are made, and finally, a standard formulation is determined before production begins. Its shortcomings are mainly twofold: first, the quality of tobacco leaves and cigarette products can only be judged by human senses; second, the fitting, selection, modification, and final determination of the formulation are highly experience-based, leading to blind spots, biases, and inefficiency.

[0004] Therefore, how to provide an efficient method for generating cigarette formulations is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0044] The core of this invention is to provide a method for generating cigarette formulations based on chemical components. In the prior art, traditional cigarette formulation design mainly relies on the personal experience of the formulation engineer and their understanding of tobacco leaf characteristics.

This allows the cigarettes corresponding to the generated formula to achieve a more efficient and closer sensory evaluation.

[0047] To enable those skilled in the art to better understand the present invention, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Example 1

[0049] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating a method for generating cigarette formulas based on chemical components, provided as an embodiment of the present invention.

[0050] See Figure 1 In this embodiment, the method for generating cigarette formulas based on chemical components includes:

[0051] S101: Obtain the chemical properties of each single-material tobacco, the inventory of each single-material tobacco, and the target chemical properties of the target tobacco.

[0052] The aforementioned single-material tobacco refers to the single-material tobacco currently in the company's inventory that can be used for cigarette production. Each single-material tobacco has a corresponding inventory quantity and corresponding chemical indicators, i.e., single-material chemical indicators. The inventory quantity of single-material tobacco is usually stored in a database for easy retrieval, while the single-material chemical indicators refer to the values ​​of various chemical indicators, including chemical components, of the single-material tobacco, such as the content of a certain chemical component in the single-material tobacco. Common chemical indicators of tobacco include 7 conventional components, 4 inorganic anions and cations, 5 polyphenols, 12 polybasic acids and higher fatty acids, 21 amino acids, 17 Amadori compounds, dichloromethane extract, pH, solanesol, and neophytadiene, etc. Specifically, they include the following:

[0053] Water-soluble total sugars, reducing sugars, total alkaloids, total nitrogen, potassium, chloride, starch, sulfate, phosphate, calcium, magnesium, neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, hyoscyamine, rutin, oxalic acid, malonic acid, succinic acid, malic acid, citric acid, vanillic acid, myristic acid, hexadecanoic acid, linoleic acid + oleic acid, linolenic acid, stearic acid, eicosanoic acid, aspartic acid, threonine, serine, asparagine, glutamic acid, glutamine, glycine, alanine, valine, cysteine, methionine, isoleucine, leucine, tyrosine, phenylalanine, 4-aminobutyric acid, lysine, histidine, tryptophan, arginine Acids, proline, 1-deoxy-1-L-alanine-D-fructose (FRU-ALA), 1-deoxy-1-L-valine-D-fructose (FRU-VAL), 1-deoxy-1-L-proline-D-fructose (FRU-PRO), 1-deoxy-1-L-phenylalanine-D-fructose (FRU-PHE), 1-deoxy-1-L-tryptophan-D-fructose (FRU-TRP), 1-deoxy-1-L-isoleucine-D-fructose (FRU-ILE), 1-deoxy-1-L-leucine-D-fructose (FRU-LEU) 1-Deoxy-1-L-Asparagine-D-Fructose (FRU-ASN), 1-Deoxy-1-L-Glutamic Acid-D-Fructose (FRU-GLU), 1-Deoxy-1-L-Aminobutyric Acid-D-Fructose (FRU-AMB), 1-Deoxy-1-L-Aspartic Acid-D-Fructose (FRU-ASP), 1-Deoxy-1-L-Glutamine-D-Fructose (FRU-GLN), 1-Deoxy-1-L-Glycine-D-Fructose (FRU-GLY), 1-Deoxy-1-L-Histidine-D-Fructose (FRU-HIS), 1-Deoxy-1-L-Threonine-D-Fructose (FRU-THR), 1-Deoxy-1-L-Tyrosine-D-Fructose (FRU-TYR), Glucosamine (GLU-AN), Dichloromethane Extract, pH, Solanesyl Alcohol, Neophytadiene.

[0054] In this embodiment, all of the aforementioned chemical indicators can be used as the types of chemical indicators included in the single-material chemical indicators. Alternatively, only a portion of the chemical indicators can be selected. For example, 36 indicators with high relevance to the formulation design can be selected from the aforementioned 70 chemical indicators and termed key chemical indicators, which can also be included as the types of chemical indicators included in the single-material chemical indicators. The specific types of chemical indicators included in the single-material chemical indicators are not specifically limited in this embodiment and depend on the specific circumstances. Correspondingly, in this embodiment, the target chemical indicator refers to the numerical values ​​of multiple chemical indicators, including chemical components, possessed by the target tobacco, such as the content of a certain chemical component in the single-material tobacco. In this embodiment, all of the aforementioned chemical indicators can be used as the types of chemical indicators included in the target chemical indicators. Alternatively, only a portion of the chemical indicators can be selected. The specific limitations are not imposed in this embodiment and depend on the specific circumstances.

[0055] The specific methods for obtaining the above-mentioned single-material chemical indicators and target chemical indicators will be described in the following examples, and will not be repeated here.

[0056] S102: Multiply the single-material chemical index by the inventory quantity to determine the inverse matrix of the inventory matrix, and multiply the target chemical index by the target total quantity to determine the target matrix.

[0057] This step requires constructing two matrices: the inverse of the inventory matrix and the inverse of the inventory matrix. Constructing the inverse matrix begins with building the inventory matrix itself. This inventory matrix is ​​formed by multiplying the chemical indicators of each ingredient by their corresponding inventory quantity. The row and column headings of this inventory matrix correspond to the names or numbers of specific tobacco ingredients, while the column and column headings correspond to the names of specific chemical indicators. The values ​​in the inventory matrix are the sum of each data point in the chemical indicators multiplied by the corresponding inventory quantity of that tobacco ingredient. This step requires calculating the inverse of the inventory matrix to subsequently calculate the specific cigarette formula.

[0058] Another type of matrix is ​​the target matrix, which can be a 1×m matrix. The item name corresponding to the row or column with "1" is the name or number of the target tobacco. The item name corresponding to the column or row can be the specific chemical indicator name. The specific value in the target matrix can be the value obtained by multiplying each data of the target chemical indicator by the total amount of the target tobacco that needs to be produced, that is, by multiplying by the target total amount of the target tobacco.

[0059] S103: Multiply the inverse of the inventory matrix with the target matrix to generate the amount of each single-material tobacco used as the target cigarette formula.

[0060] In this step, the inverse of the inventory matrix is ​​multiplied by the target matrix. The resulting matrix contains values ​​corresponding to various single-material tobaccos. These values ​​represent the content of the corresponding single-material tobacco, i.e., the amount of each single-material tobacco used. Therefore, in this step, the formula corresponding to the target tobacco can be generated based on the new matrix obtained after matrix multiplication, i.e., the target cigarette formula.

[0061] This embodiment provides a method for generating cigarette formulations based on chemical composition. Starting from the chemical indicators of single-material tobacco and target tobacco, and considering the inventory of alternative single-material tobacco and the proportion requirements of formulation design, a formulation is generated. This method can obtain a formulation that is close to the target chemical composition while meeting the dosage requirements, thereby enabling the cigarettes corresponding to the generated formulation to achieve a more efficient and closer sensory evaluation.

[0062] The specific details of the method for generating cigarette formula based on chemical composition provided by this invention will be described in detail in the following embodiments.

[0063] Example 2

[0064] Please refer to Figure 2 , Figure 2 This is a flowchart illustrating a specific method for generating cigarette formulas based on chemical components, provided as an embodiment of the present invention.

[0065] See Figure 2 In this embodiment, the method for generating cigarette formulas based on chemical components includes:

[0066] S201: Use a near-infrared spectrometer to scan the samples of each single-material tobacco and the target tobacco to obtain near-infrared spectra.

[0067] In this step, a near-infrared spectrometer can be used to scan the samples of each single-material tobacco and the target tobacco to obtain the near-infrared spectra of the corresponding samples of each single-material tobacco and the target tobacco.

[0068] S202: Determine the chemical indicators of each single-material tobacco from the near-infrared spectrum based on the near-infrared model, and determine the target chemical indicators from the near-infrared spectrum of the target tobacco.

[0069] In this step, the specific values ​​of the individual chemical indicators for each single-component tobacco can be determined from the near-infrared spectra of each individual tobacco product, and the specific values ​​of the target chemical indicators for the target tobacco can be determined from the near-infrared spectra of the target tobacco. The aforementioned near-infrared model, also known as the near-infrared multi-component quantitative model, predicts 70 chemical indicators of tobacco based on near-infrared spectroscopy. This step can be performed using a mature "Tobacco Near-Infrared Analysis System Platform," and the specific details of this model will not be elaborated upon here. After this step, the individual chemical indicators of each single-component tobacco product and the target chemical indicators of the target tobacco can be obtained.

[0070] It should be noted that, in this embodiment, the above-mentioned single-material chemical indicators and target chemical indicators can be preprocessed, including missing value processing, abnormal data exclusion, and dimension unification, etc., which are not specifically limited here.

[0071] S203: Based on the minimum material consumption limit for single-material tobacco, delete single-material tobacco products in the database whose inventory is insufficient to meet the minimum material consumption limit.

[0072] This step, along with S204 below, is used to adjust the inventory of each single-material tobacco to prevent the subsequent formulation from exceeding the upper limit of the inventory, thus making production impossible. In practice, each batch of cigarettes prepared using single-material tobacco has two limiting parameters: a lower limit and an upper limit for the amount of single-material tobacco used. In this step, specifically, based on the lower limit parameter, single-material tobacco types with insufficient inventory in the database will be deleted from the database, meaning that single-material tobacco with excessively low inventory will not be used to prepare the target tobacco for this batch.

[0073] S204: Based on the upper limit of single-material tobacco usage, adjust the inventory of single-material tobacco products in the database that exceed the upper limit of single-material tobacco usage to the inventory corresponding to the upper limit of single-material tobacco usage.

[0074] In this step, the inventory of tobacco products exceeding the upper limit of a single tobacco product will be adjusted to the inventory corresponding to the upper limit of that single tobacco product based on the upper limit parameter of the single tobacco product. This will prevent the final calculated formula from exceeding the required upper limit and will result in the adjusted inventory of each single tobacco product.

[0075] It should be noted that there is no specific order between the steps S203 to S204 and the steps S201 to S202. They can be executed in any order or in parallel. No specific restrictions are made here.

[0076] S205: Multiply the chemical properties of a single ingredient by the inventory quantity to determine the inventory matrix.

[0077] S206: Determine the inverse matrix of the inventory matrix based on the left division operation of the inventory matrix.

[0078] The specific process for determining the inventory matrix in this embodiment has been described in detail in the above embodiments and will not be repeated here. In this embodiment, the inventory matrix is ​​converted into its inverse matrix by left division. In the linear algebra operations of software such as MATLAB, the left division method is used to calculate the inverse matrix, and the result obtained has higher numerical stability.

[0079] S207: Multiply the target chemical index by the target total amount to determine the target matrix.

[0080] This step is basically the same as part of S102 in the above embodiment. For details, please refer to the above embodiment. It will not be repeated here.

[0081] S208: Add perturbations to each parameter in the target matrix to generate multiple target matrices to be used.

[0082] In this step, perturbations are added to each parameter in the target matrix. The purpose of these perturbations is to randomly fine-tune each parameter, thereby obtaining multiple fine-tuned target matrices based on the initial target matrix. This generates multiple target matrices to be used, so that multiple sets of recipes can be selected later.

[0083] Specifically, in this embodiment, the mean of the aforementioned perturbation is 0, and the distribution of the perturbation conforms to a normal distribution. The standard deviation of this perturbation is the standard deviation of the chemical index data accumulated in previous studies. The fact that the numerical distribution of the aforementioned perturbation conforms to a normal distribution and ensures that the mean of the perturbation is 0 means that the perturbation will not cause any shift in the data in the matrix as a whole. Furthermore, the standard deviation of the aforementioned chemical index data accumulated in previous studies is the standard deviation of the values ​​of various chemical indicators in common tobacco products. Limiting the standard deviation of the perturbation to the aforementioned range ensures that the data after perturbation also conforms to the actual situation and will not result in a situation where a formulation cannot be generated.

[0084] S209: Multiply the inverse of the inventory matrix by each target matrix to generate multiple sets of single-material tobacco usage as multiple sets of target cigarette formulas.

[0085] In this step, the inverse of the inventory matrix can be multiplied by the multiple target matrices obtained after perturbation, so as to obtain the target cigarette formula corresponding to each target matrix. Each set of target cigarette formulas includes a set of corresponding amounts of each single tobacco ingredient.

[0086] S210: Delete single-ingredient tobacco products in the target cigarette formula whose proportion is not within the preset range.

[0087] After obtaining the target cigarette formula, it can be further adjusted based on preset constraints. Specifically, in practice, the proportion of single-ingredient tobacco in each target cigarette formula needs to be within a certain range; exceeding or falling below this range is not in line with reality. Therefore, in this step, when the proportion of single-ingredient tobacco in the target cigarette formula is lower or higher than the preset range, the single-ingredient tobacco with a proportion outside the preset range needs to be deleted, i.e., its use is excluded. The specific value of the preset range needs to be set according to the actual situation and is not specifically limited here.

[0088] S211: Distribute the excess amount of single-ingredient tobacco in the target cigarette formula that exceeds the inventory to the single-ingredient tobacco in the target cigarette formula that does not exceed the inventory.

[0089] From the perspective of usage, the usage of a certain single-material tobacco in the target cigarette formula may exceed its corresponding inventory. Therefore, in this step, when the usage of a single-material tobacco in the target cigarette formula exceeds its corresponding inventory, the specific amount of the excess usage of a certain single-material tobacco in the target cigarette formula can be determined first. Then, the excess usage is allocated, usually evenly allocated, to other single-material tobaccos in the target cigarette formula that have not exceeded their inventory, in order to avoid the situation where the usage of a certain single-material tobacco exceeds the inventory and production cannot be carried out.

[0090] S212: Allocate the difference between the total amount of all single-ingredient tobaccos in the target cigarette formula and the total amount of the target cigarette formula to the single-ingredient tobacco with the largest amount of tobacco.

[0091] In practice, there is usually a minimum weight limit for the cigarettes corresponding to a specific target cigarette formula, meaning the weight or total amount of cigarettes used must exceed a certain value. Specifically, this step, when the total amount of all single-ingredient cigarettes in the target cigarette formula is less than the preset target amount, first determines the exact amount of the difference between the total amount of all single-ingredient cigarettes in the target cigarette formula and the target amount. Then, this difference is allocated to the single-ingredient cigarette with the highest usage in the target cigarette formula to ensure that the total amount of all single-ingredient cigarettes in the target cigarette formula meets the requirements.

[0092] It should be noted that the specific steps S210 to S212 above can be executed in multiple cycles until the final target cigarette formula meets the requirements. There is no clear order between the specific steps S210 to S212 above, and they can be executed in any order.

[0093] This embodiment provides a method for generating cigarette formulations based on chemical components. During the formulation generation process, analysis is performed based on target chemical indicators, appropriate raw materials are selected, and their proportions are determined. This ensures that the obtained cigarette formulation is highly similar to the target chemical components, and this precise matching ensures that the sensory evaluations of the two are more closely aligned. By precisely controlling the content of each component, the overall harmony of the formulation can be further optimized. This method not only improves the accuracy of the formulation but also ensures that the final product meets the expected standards in terms of sensory characteristics, achieving a high degree of consistency with the target sample.

[0094] In the specific process of formula generation, the actual inventory of candidate single-element tobaccos, as well as the specific proportions and usage limits of each single-element tobacco in the formula, were fully considered. This ensured that the designed formula not only met the preset proportion requirements but also complied with actual usage limits, avoiding production bottlenecks caused by insufficient or excessive raw materials. By calculating and rationally allocating the usage of each single-element tobacco, the final design scheme was made feasible, making full use of existing resources while ensuring cost-effectiveness and smooth production. This method effectively improves the practicality and operability of the formula generation scheme, providing strong support for actual production.

The inventory includes 300 types of single-material tobaccos, with a target total quantity of 30,000 dan (a unit of weight).
