Description

Technical Field

[0001] This invention relates to the field of cigarette flavoring formulation, and more particularly to a method for determining the relative density standard and quality of cigarette flavoring. Background Technology

[0002] Flavoring and additives are crucial steps in cigarette production. Flavoring enhances and improves the natural aroma of tobacco, masks off-flavors, and improves taste. Furthermore, it imparts different aroma profiles to cigarettes, such as light, strong, sweet, fruity, and chocolate notes, to satisfy diverse smoking preferences. Adding additives improves the flavor and aroma of cigarettes, reduces or eliminates unpleasant odors and irritations, and also improves tobacco toughness, combustibility, and preservation properties. The quality of flavoring and additive liquids significantly impacts the finished cigarette product; therefore, quality control of these liquids is paramount.

[0003] Currently, quality control of flavoring and additive liquids mainly employs the following method: For flavoring and additive liquids with the same formula, quality control personnel determine a standard product based on their personal experience and flavoring experiments. Then, for different batches of flavoring and additive liquids, flavoring and additives are applied separately, and sensory comparisons are conducted between the flavored and additive-treated cigarettes and the standard product. The quality of different batches of flavoring and additive liquids is determined based on the comparison results. This method is cumbersome and highly dependent on human experience. How to achieve more objective and efficient quality control of flavoring and additive liquids is increasingly attracting the attention of those skilled in the art. Summary of the Invention

[0030] Relative density is an important indicator for measuring the physical properties of flavorings and fragrances. This indicator can be easily obtained using instruments. Each flavoring monomer and raw material has its corresponding physical properties, and relative density has corresponding standards. Therefore, the finished flavorings and fragrances also have fixed physical properties, and their relative density should have a certain range and standard. Therefore, the inventors of this application considered evaluating the quality of cigarette additive liquids (i.e., flavoring liquids or additive liquids) by determining the quantifiable range of their relative density. Based on this inventive concept, this invention provides a method for determining the relative density standard of cigarette additive liquids, comprising:

[0031] Determination of standard density:

[0032] S01) Determine the theoretical average relative density of the added liquid based on the ratio of the added liquid and the upper and lower limits of the relative density of each monomeric flavoring;

[0033] S02) Determine the actual average relative density based on the theoretical average relative density;

[0034] S03) Determine the standard range of the relative density of added flavorings based on the actual average relative density and tolerance;

[0035] The above-mentioned additive liquid is a flavoring liquid or a flavoring liquid.

[0036] In the steps related to determining the standard density in the above-described method provided in this embodiment of the invention:

[0037] Step S01) is the step of determining the theoretical average relative density. The relative density of a substance is the ratio of its actual density to the density of a standard substance. For flavorings, the standard substance is water. The relative density of a flavoring is the ratio of its density to that of pure water at 20°C, using pure water as the reference substance (i.e., the standard substance). Each monomeric flavoring has a clearly defined upper and lower limit for its relative density. According to the formula for adding flavorings and additives to cigarettes, the prepared flavoring liquid and additive liquid are mixtures. Ideally, the volume of the mixture is equal to the sum of the volumes of its components. The mass percentage of each component in each formula is fixed. The formula components include monomeric flavorings and additives (such as alcohol, water, propylene glycol, etc.). Each monomeric flavoring has an upper and lower limit for its relative density, and each additive has a definite density. Therefore, through V=m / ρ, ρ=d×ρ 水 By taking the maximum and minimum relative densities of each spice, the maximum and minimum theoretical volumes of the additive liquid with this ratio can be obtained. Furthermore, the maximum and minimum theoretical relative densities of the additive liquid can be obtained, and thus the average theoretical relative density can be obtained.

[0038] Specifically, this can be calculated using V=m / ρ, ρ=d×ρ 水First, calculate the theoretical maximum volume V of the added liquid. max That is, the sum of the volumes of all components.

[0039]

[0040] m represents the mass of the added liquid, a1, a2, ... a n The percentage content of each monomeric flavoring agent, d 1min d 2min ...d nmin These are the lower limits of the relative density of their corresponding monomeric fragrances, where n represents the number of monomeric fragrances; b1, b2, ..., b x The percentage content of each adjuvant is ρ. 剂1 , ρ 剂2 ...ρ 剂x , where are the densities of their respective additives, and x is the type of additive.

[0041] To further simplify:

[0042]

[0043] a i d represents the percentage content of each monomeric flavoring agent. imin The lower limit of the relative density of its corresponding monomeric fragrance; b i ρ represents the percentage content of each adjuvant. 剂i The measured density of its corresponding additive.

[0044] according to V max =m / p min =m / d min r 水 The theoretical minimum relative density of the added liquid can be obtained. d’ min as follows:

[0045]

[0046] Using the same method, the theoretical maximum relative density of the added liquid can be obtained. d’ max as follows:

[0047]

[0048] Based on the above maximum relative density d max 'and the minimum relative density d min The average value of the theoretical relative density of the added liquid is obtained by calculating the mean value, as shown in Equation I:

[0049] Formula I

[0050] In formula I, d 均 'This represents the theoretical average relative density of the added liquid; a' i d represents the percentage content of each monomeric flavoring agent. i max and d i min These are the upper and lower limits of the relative density of their respective monomeric flavorings, where n is the number of monomeric flavorings; b i ρ represents the percentage content of each adjuvant. 剂i Let x be the measured density of the corresponding additive, and x be the type of additive.

[0051] The above step S02) is based on the obtained theoretical average relative density d 均 Determine the actual mean relative density d 均 The steps. Considering the above theoretical average relative density d 均 The values ​​are derived from the maximum and minimum volumes of the additive liquid under ideal conditions. However, the actual volume may not equal the sum of the volumes of all components. Typically, the actual volume is slightly smaller than the sum of the volumes. To reduce this data deviation, the inventors of this application considered establishing a relationship between the actual volume and the sum of the volumes of the cigarette additive liquid, and thus... 均 Make corrections to ensure that the obtained mean relative density d 均 More accurate.

[0052] The applicant discovered through research that, for a given cigarette additive liquid with a specific formula, the ratio of its actual volume to its total volume is a relatively fixed value. Therefore, in this embodiment, the ratio of the actual volume to the total volume of the cigarette additive liquid with the same proportion is used as a correction coefficient I to adjust the total volume V of the cigarette additive liquid. 叠 Make corrections to determine the actual volume V. 实 Furthermore, since the density of a substance is proportional to its volume, this correction factor I can also be applied to the theoretical average relative density d obtained in step S01). 均 'Make corrections to determine the actual mean relative density d' 均 Therefore, the actual mean relative density can be determined according to Equation II:

[0053] Formula II

[0054] In Equation II, d 均 is the actual average relative density; I is the correction factor, which is the ratio of the actual volume of the cigarette additive liquid to the sum of the volumes of its components.

[0055] That is, I=V 实 / V 叠 V 实V is the actual volume of the liquid added to cigarettes. 叠 The sum of the volumes of all components in the cigarette additive liquid is referred to as the superimposed volume. Since the actual volume of the cigarette additive liquid is very close to the superimposed volume, V is used to improve the accuracy of the I value. 实 The preferred method is to use the mass m and measured density ρ of the added liquid in cigarettes. 实 The calculation yields the following result:

[0056]

[0057] Among them, the measured density ρ of the cigarette additive liquid 实 It can be measured using a density and viscosity analyzer.

[0058]

[0059] V 叠 The sum of the volumes of all components of the additive liquid for this cigarette; m is the mass of the additive liquid; a1, a2...a n The percentage content of each monomeric flavoring agent is ρ. 香1 , ρ 香2 ...ρ 香n These are the measured densities of their corresponding monomeric fragrances, where n represents the number of monomeric fragrances; b1, b2, ..., b x The percentage content of each adjuvant is ρ. 剂1 , ρ 剂2 ...ρ 剂x These are the measured densities of their corresponding additives, where x represents the type of additive. The measured density of monomeric fragrances can be obtained using a density and viscosity analyzer.

[0060] Further simplification yields:

[0061]

[0062] a i ρ represents the percentage content of each monomeric flavoring agent. 香i The measured density of its corresponding monomeric fragrance; b i ρ represents the percentage content of each adjuvant. 剂i The measured density of its corresponding additive.

[0063] Furthermore, the aforementioned V 实 and V 叠 Substitute into I=V 实 / V 叠 Thus, I is obtained as shown in Equation III:

[0064] Formula III

[0065] Furthermore, substituting Equation III into Equation II, we obtain:

[0066]

[0067] Based on the above steps S01) and S02), the average actual relative density d of the cigarette additive liquid with this ratio can be determined. 均 Then, according to S03), based on the obtained average relative density d... 均 By determining the tolerance, the standard range of the relative density of the additive liquid can be established, thus defining the standard relative density of the additive liquid. Further, the additive liquid is a flavoring liquid with a tolerance range of ±0.0070, therefore the standard range of the relative density of the flavoring liquid in this formulation is determined as d. 均 ±0.0070; or, if the added liquid is a feed liquid, the tolerance range is ±0.0080, and the standard range of the relative density of the feed liquid of this ratio is determined as d. 均 ±0.0080.

[0068] As can be seen from the above, the method provided in this embodiment of the invention can determine the standard range of the relative density of the cigarette additive liquid based on the known formula of the additive liquid, without the need for repeated debugging experiments, and with low reliance on human experience, which is conducive to more objective and efficient quality control of flavoring and additive liquids. Furthermore, after determining the theoretical average relative density of the additive liquid, the method also includes a step of correcting it to obtain the actual average relative density, thereby making the final determined standard range of relative density more accurate. In summary, the method for determining the standard density of cigarette additive liquid provided by this invention has the advantages of simplicity, efficiency, objectivity, and accuracy.

[0069] Another embodiment of the present invention also provides a method for determining the quality of cigarette additive liquid, which includes:

[0070] Step a) Determine the standard range of the relative density of the cigarette additive liquid to be tested according to the method described in the above embodiments;

[0071] Step b) Detect the relative density of the additive liquid in the cigarette to be tested;

[0072] Step c) Determine the quality of the cigarette additive liquid to be tested based on the relative density measured in step a) and the standard range determined in step b).

[0073] The added liquid is a flavoring liquid or a additive liquid;

[0074] There is no restriction on the order of steps a) and b).

[0075] Preferably, step c) above specifically includes:

[0076] Determine whether the relative density measured in step a) is within the standard range determined in step b); if yes, then the quality of the cigarette additive liquid is determined to meet the requirements; otherwise, the quality of the cigarette additive liquid is determined to not meet the requirements.
