Description

一种经增烟处理的低危害卷烟 技术领域
本发明属于低危害卷烟技术领域，特别涉及一种经增烟处理的低危害卷烟。
背景技术
为了消费者身体健康，烟草行业多年来一直推动卷烟产品的减害降焦，传统烟的焦油含量从20mg以上逐年下降到10mg左右。但较低的危害性和较好的满足感常常是一对矛盾。3mg焦油卷烟属于一种对人体健康危害性小的卷烟，它的一个缺陷在于卷烟感官上的烟雾量较少。6mg以上焦油卷烟的烟雾量就相对较好，但危害性也相应增加。
因此，有必要研发出一种全新的经增烟处理的低危害卷烟，即在低危害卷烟的基础上进一步提升卷烟发烟效果，同时也要考虑降低增烟剂危害的负面效果，并延长卷烟货架期。
发明内容
本发明目的之一是为了提供一种全新的经增烟处理的低危害卷烟，即在低危害卷烟的基础上进一步提升卷烟发烟效果，同时降低增烟剂的负面效果；本发明的目的之二在于延长卷烟货架期。

进一步地，制造所述经增烟处理的烟草薄片的烟草薄片原料包括传统烟草薄片浆料和增烟剂。本发明在制造经增烟处理的烟草薄片时，可采用传统烟草薄片浆料和增烟剂作为烟草薄片原料，从而降低调整烟草薄片口味、香味等感官度的难度，缩短研发周期，也有利于简化生产工艺。
进一步地，所述传统烟草薄片浆料直接制得的烟草薄片对应的烟支焦油释放量小于或等于6mg/支，优选小于或等于3mg/支，更优选小于或等于1mg/支。本发明在传统烟草薄片的基础上，通过增烟处理处理，使得低焦油含量的烟草薄片也能产生于高焦油含量的烟草薄片相当的烟雾量，从而实现在低危害的前提下满足消费者对烟雾量需求的技术效果。
进一步地，所述增烟剂在所述经增烟处理的烟草薄片中的质量百分比大于或等于5％。本发明在大量实验的基础上发现，经增烟处理的烟草薄片中增烟剂的质量百分比大于或等于5％时，能产生感官上较为明显的增烟效果，而且由于增烟剂用量很低，增烟剂带来的危害很小，对烟草薄片口味、香味等感官度的影响也很小，可以不用调整烟草薄片口味、香味等感官度，大大缩短研发周期，卷烟成本增加很少。
进一步地，所述增烟剂在所述经增烟处理的烟草薄片中的质量百分比大于或等于10％。本发明在大量实验的基础上发现，经增烟处理的烟草薄片中增烟剂的质量百分比大于或等于10％时，能产生感官上非常明显的增烟效果，而且由于增烟剂用量较低，增烟剂带来的危害较小，对烟草薄片口味、香味等感官度的影响也较小，调整烟草薄片口味、香味等感官度的难度较低，可以缩短研发周期，卷烟成本增加较少。

进一步地，所述无害有机化合物包括糖类和/或糖醇类。更进一步地，所述糖类和/或糖醇类包括丁四醇、戊五醇、己六醇中的至少一种。由于增烟剂选用常用食品添加剂，安全性非常高，即使卷烟被误食也不会造成严重后果。
进一步地，所述经增烟处理的低危害卷烟的焦油目标当量为T target·mg/支，所述经增烟处理的烟草薄片占所述气溶胶生成基质的质量百分比为M sheet，所述经增烟处理的烟丝占所述气溶胶生成基质的质量百分 比为M tobacco，制造所述经增烟处理的烟草薄片的烟草薄片原料包括传统烟草薄片浆料和第一增烟剂，所述传统烟草薄片浆料直接制得的烟草薄片对应的烟支焦油释放量为T sheet·mg/支，所述第一增烟剂占所述经增烟处理的烟草薄片的质量百分比为M smoke1，所述第一增烟剂的增烟系数为S 1，所述第一增烟剂的极限增烟焦油当量为T limit1，所述第一增烟剂的极限增烟焦油当量所对应的增烟剂含量为M limit1，所述经增烟处理的烟丝包括传统烟丝和第二增烟剂，所述传统烟丝对应的烟支焦油释放量为T tobacco·mg/支，所述第二增烟剂占所述经增烟处理的烟丝的质量百分比为M smoke2，所述第二增烟剂的增烟系数为S 2，所述第二增烟剂的极限增烟焦油当量为T limit2，所述第二增烟剂的极限增烟焦油当量所对应的增烟剂含量为M limit2，上述参数在±5％的误差下满足：
T target＝M sheet×(T sheet+T limit1－S 1×(M limit1－M smoke1) 2)+M tobacco×(T tobacco+T limit2－S 2×(M limit2－M smoke2) 2)
的关系。通过上述公式可以获得卷烟整体的焦油当量，一方面可以便于在卷烟研制过程中计算烟草薄片和烟丝所需添加的增烟剂含量，另一方面可以在卷烟产品包装上进行焦油当量标识，便于消费者选择所需烟雾产生量的卷烟产品。

进一步地，所述气溶胶生成基质仅包括经增烟处理的烟丝，所述经增烟处理的烟丝包括传统烟丝和增烟剂，所述增烟剂的沸点小于或等于350℃。当气溶胶生成基质仅包括经增烟处理的烟丝时，经增烟处理的低危害卷烟可以作为点燃抽吸的燃烧型卷烟，将增烟剂的沸点选定为小于或等于350℃时，可以增加卷烟的实际雾化量，同时尽可能避免发生燃烧反应。
进一步地，所述气溶胶生成基质中同时包含经增烟处理的烟草薄片与经增烟处理的烟丝。当气溶胶生成基质同时包括经增烟处理的烟草薄片与经增烟处理的烟丝时，经增烟处理的低危害卷烟可以作为既适合点燃抽吸又适合加热烟具进行加热抽吸的两用型卷烟。两用烟一方面可以使用加热烟具加热抽吸，免去了乘坐飞机无法携带打火机所带来的烦恼，另一方面可以直接点燃抽吸，可以像普通烟一样方便分享给亲朋好友，交际功能较强。
进一步地，所述经增烟处理的烟草薄片与所述经增烟处理的烟丝的质量比介于为1:9和9:1之间。经增烟处理的烟草薄片与经增烟处理的烟丝的质量比介于为1:9和9:1之间，可以调整和拼配出不同的卷烟口味和香味，消费者也可以按日常消费习惯，根据点燃抽吸和加热抽吸的频率，选择适合的两用型卷烟。
进一步地，所述经增烟处理的低危害卷烟由加热烟具在200℃下加热所产生的总粒相物大于或等于14.0毫克。本发明的经增烟处理的低危害卷烟在200℃下加热所产生的总粒相物即可以大于或等于14.0毫克，从而满足消费者对烟雾量的需求。经增烟处理的低危害卷烟在200℃下加热时，所产生醛酮类有害物质明显低于在240℃下加热。

具体实施方式
以下在具体实施方式中详细叙述本专利的特征以及优点，其内容足以使本领域技术人员了解本专利的技术内容并据以实施，且根据本说明书、权利要求及附图，本领域技术人员可轻易地理解本专利的目的及优点。
本发明所涉及的经增烟处理的低危害卷烟，包括卷烟纸、过滤嘴以及气溶胶生成基质，所述气溶胶生成基质包括经增烟处理的烟草薄片和/或经增烟处理的烟丝。
实施例1：经增烟处理的烟草薄片的制造方法一
制造经增烟处理的烟草薄片的第一种方法：按照传统烟草薄片原有工序制造经增烟处理的烟草薄片，只是在制造经增烟处理的烟草薄片过程中，将增烟剂直接混入传统烟草薄片浆料中，即按如下步骤：
步骤1：按照传统稠浆法等制造烟草薄片的工艺准备传统烟草薄片浆料；
步骤2：往传统烟草薄片浆料里加入适量的增烟剂；
步骤3：按照传统稠浆法等制造成经增烟处理的烟草薄片。
由于该方法可以直接按照原有工序制造经增烟处理的烟草薄片，不需要对制造设备和制造工艺进行改造。同时，由于增烟剂均匀混入传统烟草薄片浆料中，经增烟处理的烟草薄片表面和传统烟草薄片一样光洁，也不容易接触到空气中的水分从而潮解。
实施例2：经增烟处理的烟草薄片的制造方法二
制造经增烟处理的烟草薄片的第二种方法：按照传统烟草薄片原有工序制造传统烟草薄片后，将增烟剂附着于经增烟处理的烟草薄片的表面，即按如下步骤：
步骤1：按照传统稠浆法等制造烟草薄片的工艺准备传统烟草薄片浆料；
步骤2：按照传统稠浆法等制造成传统烟草薄片；
步骤3：向传统烟草薄片中直接混合适量的增烟剂，获得经增烟处理的烟草薄片，可以观察到增烟剂附着于经增烟处理的烟草薄片的表面。
由于增烟剂通过直接混合等方式直接附着于经增烟处理的烟草薄片的表面，有利于提高增烟剂的雾化效果，特别是卷烟在点燃或高温加热的情况下，烟草薄片表面附着的增烟剂在受到些许热量时便会快速雾化，从而进一步降低危害。
实施例3：经增烟处理的烟丝的制造方法一
制造经增烟处理的烟丝的第一种方法：按照烟丝原有工序制造经增烟处理的烟丝，只是在制造经增烟处理的烟丝过程中，直接渗入烟丝内部，即按如下步骤：
步骤1：按照传统制造烟丝的工艺预处理传统烟丝；
步骤2：向传统烟丝喷洒适量的渗透性的喷洒增烟剂溶液；
步骤3：按照传统制造烟丝的工艺继续进行干燥等处理，制造成经增烟处理的烟丝。
由于该方法中增烟剂直接渗入经增烟处理的烟丝内部，只需要在原有传统烟丝制造工序中的加料环节中添加增烟剂即可，不需要对制造设备和制造工艺进行改造。由于增烟剂均匀渗入经增烟处理的烟丝内部，经增烟处理的烟丝表面和传统烟丝一样光洁，也不容易接触到空气中的水分从而潮解。
实施例4：经增烟处理的烟丝的制造方法二
制造经增烟处理的烟丝的第二种方法：按照烟丝原有工序制造经增烟处理的烟丝，只是在制造经增烟处理的烟丝过程中，通过混合等方式直接附着于烟丝的表面，即按如下步骤：
步骤1：按照传统制造烟丝的工艺预处理传统烟丝；
步骤2：按照传统制造烟丝的工艺继续进行干燥等处理；
步骤3：向传统烟丝中直接混合适量的增烟剂，制造成经增烟处理的烟丝，可以观察到增烟剂附着于经增烟处理的烟丝的表面。
由于该方法中增烟剂混合等方式直接附着于烟丝的表面，有利于提高增烟剂的雾化效果，特别是卷烟在点燃或高温加热的情况下，烟草薄片表面附着的增烟剂在受到些许热量时便会快速雾化，大部分增烟剂未经过燃烧反应或高温分解，从而进一步降低危害。
实施例5：经增烟处理的低危害加热型卷烟的制造方法
根据口味、香味、卷烟整体的焦油当量等要求，适当选用实施例1和2制造的经增烟处理的烟草薄片作为气溶胶生成基质，按照传统卷烟的制造方法，对烟草薄片进行切丝或卷曲并用卷烟纸与过滤嘴一同进行卷包，必要时也可以增加冷却段、爆珠等附加结构，制造成经增烟处理的低危害加热型卷烟。
实施例6：经增烟处理的低危害燃烧型卷烟的制造方法
根据口味、香味、卷烟整体的焦油当量等要求，适当选用实施例3和4制造的经增烟处理的烟丝作为气溶胶生成基质，按照传统卷烟的制造方法，将烟丝用卷烟纸与过滤嘴一同进行卷包，必要时也可以增加爆珠等附加结构，制造成经增烟处理的低危害燃烧型卷烟。
实施例7：经增烟处理的低危害两用型卷烟的制造方法
根据口味、香味、卷烟整体的焦油当量等要求，适当选用实施例1～4制造的经增烟处理的烟草薄片和经增烟处理的烟丝作为气溶胶生成基质，按照传统卷烟的制造方法，对烟草薄片进行切丝或卷曲，混入烟丝后，用卷烟纸与过滤嘴一同进行卷包，必要时也可以增加冷却段或爆珠等附加结构，制造成经增烟处理的低危害两用型卷烟。
当选用具有低潮解性的增烟剂时，上述实施例1～7的制造生产环境湿度控制范围可以拓宽至30％-60％，即无需在特殊密闭的干燥生产车间进行生产，从而大大降低生产能耗。
实施例8：总粒相物实验一
卷烟烟雾量的一种常用表征手段为总粒相物(Total Particulate Material，简称TPM)，可以根据GB/T 19609-2004《卷烟用常规分析用吸烟机测定总粒相物和焦油》提供的方法进行实验，获得单位重量烟草材料的总粒相物生成量(单位为mg/支)。
选用实施例3的方法制造经增烟处理的烟丝，其中选用的传统烟丝为3mg中南海烟支里吹出的烟丝，喷洒的增烟剂溶液为50％丁四醇的水溶液，分别调整增烟剂溶液用量，依次制得丁四醇含量占最终干燥后的经增烟处理的烟丝质量百分比为5％、10％、15％、20％和25％的5种经增烟处理的烟丝。
将上述传统烟丝和5种经增烟处理的烟丝分别按照实施例6中的制造方法包卷成卷烟。
首先，由评烟师采用点燃抽吸方式按照GB5606.4-2005及中式卷烟感官评价方法进行感官评吸，5种经增烟处理的低危害卷烟相比于未添加增烟剂的传统低危害卷烟，呛喉感、鼻腔刺激及干燥感均有所减小，余味略微不净，香味的透发性中等稍显不足。
其次，根据GB/T 19609-2004的方法测定卷烟主流烟气中的总粒相物，具体结果参见图1。
可以看到总粒相物会随作为增烟剂的丁四醇在烟丝中的质量百分比的增加而递增，但提升幅度逐渐减小，出现了边际效应递减，并且当增烟剂质量百分比达到25％时，增烟效果接近极限，即使再进一步增加增烟剂的质量百分比，难以看出进一步的增烟效果。
特别是丁四醇含量占15％的情况下，剑桥滤片捕集的烟气总粒相物TPM值为8.80，而丁四醇含量为0％的传统烟丝的TPM值为5.08，提升幅度达到了73.2％，增烟效果显著。
实施例9：红外遮光率实验一
卷烟烟雾量的另一种常用表征手段为红外遮光率，可以将样品在吸烟机上按照加拿大深度抽吸模式，采用点燃抽吸的方式测定的红外遮光率，数值越大代表烟雾浓度越高。
按实施例8方法制造传统低危害卷烟和丁四醇含量占15％的经增烟处理的低危害卷烟，分别在吸烟机上按照加拿大深度抽吸模式(抽吸时间设定为3秒)，采用点燃抽吸的方式测定的红外遮光率。
表1 不同卷烟红外遮光率：
红外遮光率/％ 传统低危害卷烟 含15％丁四醇卷烟
第一口 42 48
第二口 46 57
第三口 49 60
第四口 47 63
第五口 46 64
第六口 45 62
第七口 45 60
表1中数值越大代表烟雾浓度越高，由此可以看出烟雾量的实际大小。很明显，添加丁四醇作为增烟剂后的样品比未添加的要高出许多。
实施例10：总粒相物实验二
选用实施例3的方法制造经增烟处理的烟丝，其中选用的传统烟丝为3mg中南海烟支里吹出的烟丝，喷洒的增烟剂溶液为50％戊五醇的水溶液，分别调整增烟剂溶液用量，依次制得戊五醇含量占最终干燥后的经增烟处理的烟丝质量百分比为5％、10％、15％、20％和25％的5种经增烟处理的烟丝。
将上述传统烟丝和5种经增烟处理的烟丝分别按照实施例6中的制造方法包卷成卷烟。
首先，由评烟师采用点燃抽吸方式按照GB5606.4-2005及中式卷烟感官评价方法进行感官品吸，5种经增烟处理的低危害卷烟相比于未添加增烟剂的传统低危害卷烟，呛喉感、鼻腔刺激及干燥感均有所减小，余味略微不净，香味的透发性中等稍显不足。
其次，根据GB/T 19609-2004的方法测定卷烟主流烟气中的总粒相物，具体结果参见图2。
可以看到总粒相物会随作为增烟剂的戊五醇在烟丝中的质量百分比的增加而递增，但提升幅度逐渐减小，出现了边际效应递减，并且当增烟剂质量百分比达到25％时，增烟效果接近极限，即使再进一步增加增烟剂的质量百分比，难以看出进一步的增烟效果。
特别是戊五醇含量占15％的情况下，剑桥滤片捕集的烟气总粒相物TPM值为8.99，而戊五醇含量为0％的传统烟丝的TPM值为5.08，提升幅度达到了77.0％，增烟效果显著。
实施例11：红外遮光率实验二
按实施例10方法制造传统低危害卷烟和戊五醇含量占15％的经增烟处理的低危害卷烟，分别在吸烟机上按照加拿大深度抽吸模式(抽吸时间设定为3秒)，采用点燃抽吸的方式测定的红外遮光率。
表2 不同卷烟红外遮光率：
红外遮光率/％ 传统低危害卷烟 含15％戊五醇卷烟
第一口 42 76
第二口 46 76
第三口 49 77
第四口 47 79
第五口 46 80
第六口 45 77
第七口 45 78
表2中数值越大代表烟雾浓度越高，由此可以看出烟雾量的实际大小。很明显，添加戊五醇作为增烟剂后的样品比未添加的要高出许多。
除了上述丁四醇和戊五醇外，各类丁三醇、戊三醇、戊四醇、已三醇、已四醇、已五醇、已六醇、庚四醇、庚五醇、庚六醇、庚七醇等糖类、糖醇类多元醇物质均表现出增烟效果。
实施例12：卷烟危害性评价指数实验
作为低危害卷烟的增烟剂，优选无害有机化合物，使得经增烟处理的低危害卷烟在添加增烟剂后的单位焦油H值小于或等于0.6，则可以认为卷烟危害性处于较低水平，其中单位焦油H值＝H值/焦油含量或当量。如果增烟剂进一步选用丁四醇、戊五醇、己六醇等糖类和/或糖醇类常用食品添加剂，则安全性会更高，即使卷烟被误食也不会造成严重后果。
H值为卷烟危害性评价指数，计算公式如下：
Figure PCTCN2020132614-appb-000001
公式中：
H为卷烟危害性评价指数；
X CO为卷烟主流烟气中CO释放量实测值，单位为mg/支；
X HCN为卷烟主流烟气中HCN释放量实测值，单位为μg/支；
X NNK为卷烟主流烟气中NNK释放量实测值，单位为ng/支；

X 巴豆醛为卷烟主流烟气中巴豆醛释放量实测值，单位为μg/支；
C CO、C HCN、C NNK、C NH3、C B[a]P、C 苯酚、C 巴豆醛分别为全国卷烟主流烟气中释放量加权平均值。
样品CO的测定依据标准YC/T30-1996；HCN的测定依据标准YC/T253-2008；NNK的测定依据标准GB/T23228-2008；NH3的测定依据标准烟草行业标准；苯并[a]芘的测定依据标准GB/T21130-2007；苯酚的测定依据标准YC/T255-2008；巴豆醛的测定依据标准YC/T254-2008。
传统卷烟焦油含量是指去除烟碱和水分的总粒相物，单位为mg，焦油含量与卷烟雾化发生量呈正向关系，焦油含量越高，卷烟雾化发生量越大。但在传统卷烟中通常将焦油全部视作视作卷烟产生的危害物质，而本发明中的经增烟处理的低危害卷烟实际焦油含量较低，但为了便于将其雾化发生量与传统卷烟进行对比，定义焦油当量的概念，即经增烟处理的低危害卷烟焦油当量是指去除烟碱和水分的总粒相物，单位为mg，具体测量方法可参照GB/T 19609-2004中测定卷烟主流烟气中的焦油的方法。
选用实施例3的方法制造经增烟处理的烟丝，其中选用的其中选用的传统烟丝为单料烟湖南湘西龙山C3F的烟丝，喷洒的增烟剂溶液为50％丁四醇的水溶液、50％戊五醇的水溶液、50％己六醇的水溶液，分别调整增烟剂溶液用量，依次制得丁四醇含量占最终干燥后的经增烟处理的烟丝质量百分比为15％、戊五醇 含量占最终干燥后的经增烟处理的烟丝质量百分比为15％、己六醇含量占最终干燥后的经增烟处理的烟丝质量百分比为15％的3种经增烟处理的烟丝。
按照实施例6中的制造方法依次包卷成传统卷烟，丁四醇含量占15％、戊五醇含量占15％、己六醇含量占15％的经增烟处理的低危害卷烟这4款样品。对以上卷烟分别在根据上述方法测定卷烟危害性评价指数。
表3 不同卷烟的卷烟危害性评价指数：
样品 传统卷烟 丁四醇 戊五醇 己六醇
均吸阻(kPa) 1.106 0.988 1.005 1.032
X CO(mg/支) 8.2 8.5 8.4 8.4
X HCN(ug/支) 74.0 55.3 57.6 57.1
X NNK(ng/支) 3.4 2.5 2.8 2.3
X NH3(ug/支) 6.7 7.0 6.3 6.7
X B[a]P(ng/支) 8.5 8.2 8.2 7.4
X 苯酚(ug/支) 28.0 14.7 14.4 12.5
X 巴豆醛(ug/支) 13.2 12.4 11.2 10.8
危害性指数H值 8.0 6.5 6.4 6.0
总粒相物TPM 14.3 16.6 17.3 17.1
焦油含量或当量 11.7 12.9 14.0 13.8
单位焦油H值 0.6884 0.5037 0.4563 0.4349
由表3可见，添加丁四醇、戊五醇、己六醇作为增烟剂的卷烟的单位焦油H值均小于或等于0.65，显著优于传统卷烟，更进一步地，单位焦油H值均小于或等于0.6，或小于或等于0.55，或小于或等于0.5，或小于或等于0.45；更进一步的，X HCN值小于或等于60μg/支；或者X NNK值小于或等于3.0ng/支；或者X NH3值小于或等于6.5μg/支；或者X B[a]P值小于或等于8.2ng/支；或者X 苯酚值小于或等于25μg/支；或者X 巴 豆醛值小于或等于12.5μg/支；则可以认为卷烟危害性处于较低水平。
实施例13：卷烟货架期实验
卷烟货架期主要取决于卷烟产品的吸湿性。例如电加热气溶胶生成制品通常由于包含大量高潮解性的丙二醇和丙三醇，从而比常规烟丝卷烟具有更高水分含量，这会大大降低此类电加热气溶胶生成制品的货架期。而且由于水的比热较大，对于包含高潮解性物质的电加热气溶胶生成制品，必须提高烟具加热温度， 增加了有机物裂解而产生有害物质的风险。常规烟丝卷烟也不能添加高潮解性物质，不然会降低卷烟可燃性和持续燃烧性。因此，在为卷烟进行增烟处理过程中，优选具有低潮解性的增烟剂。
增烟剂的潮解性可通过以下方式获得：
称取15.000±0.004g样品放置于40℃、80％RH恒温恒湿箱中，考察不同时间长度下样品吸水增重情况。
表4 不同增烟剂潮解性：
Figure PCTCN2020132614-appb-000002
可以通过计算120min的增重百分比，确定增烟剂的潮解性。如果120min的增重百分比小于或等于8％，则可认为具有低潮解性；如果小于或等于5％则可认为具有很低潮解性；如果小于或等于1％则可认为具有超低潮解性。
按实施例8方法制造传统低危害卷烟和丁四醇含量占15％的经增烟处理的低危害卷烟。按实施例10方法制造戊五醇含量占15％的经增烟处理的低危害卷烟。
选用3mg中南海烟支里吹出的烟丝，喷洒丙三醇，制得丙三醇含量占最终烟丝质量百分比为15％的对照组烟丝样品，并按照实施例6中的制造方法包卷成对照组卷烟样品，在制造过程需在特殊密闭的干燥实验室中进行，确保实验前卷烟未潮解并出现黄斑。
如图3所示，分别将上述样品敞开放置于高温高湿(40℃，80％RH)环境中，观察烟支潮解后表面出现黄斑的情况。为了在实验中不碰触烟支，采用拍摄如图3中的照片，然后统计照片中的黄斑投影面积(单位为mm 2/支)，照片中的黄斑投影面积与烟支实际黄斑面积之比约为1:π。对根据不同时间点的黄斑投影面积(单位为mm 2/支)进行记录。
表5 不同卷烟、不同时间点的黄斑投影面积：
放置时间 传统低危害 含15％丁四醇 含15％戊五醇 含15％丙三醇
  卷烟 卷烟 卷烟 卷烟
0小时 0 0 0 0
1小时 0 1 1 11
2小时 1 2 2 18
4小时 3 6 7 52
6小时 5 10 12 60
25小时 19 39 43 86
由表5可见，由于所选用的丁四醇和戊五醇均具有低潮解性，使得卷烟在40℃、80％RH环境中连续放置25小时后的黄斑面积仍小于50mm 2/支。除上述包含烟丝的卷烟外，包含经丁四醇和戊五醇等低潮解性增烟剂进行增烟处理的烟草薄片的卷烟也具有较长的货架期。此外，采用丁四醇和戊五醇等低潮解性增烟剂的卷烟无需在特殊密闭的干燥环境下制造。
实施例14：卷烟焦油当量实验
传统卷烟焦油含量是指去除烟碱和水分的总粒相物，单位为mg，焦油含量与卷烟雾化发生量呈正向关系，焦油含量越高，卷烟雾化发生量越大。但在传统卷烟中通常将焦油全部视作卷烟产生的危害物质，而本发明中的经增烟处理的低危害卷烟实际焦油含量较低，但为了便于将其雾化发生量与传统卷烟进行对比，定义焦油当量的概念，即经增烟处理的低危害卷烟焦油当量是指去除烟碱和水分的总粒相物，单位为mg，具体测量方法可参照GB/T 19609-2004中测定卷烟主流烟气中的焦油的方法。
按实施例8方法制造传统低危害卷烟和增烟剂丁四醇含量分别占5％、10％、15％、20％和25％的5种经增烟处理的低危害卷烟。参照GB/T 19609-2004中测定卷烟主流烟气中的焦油的方法，分别测定传统低危害卷烟的焦油含量以及5种经增烟处理的低危害卷烟的焦油当量，具体结果参见图4。
通过图4可以看到，经增烟处理的低危害卷烟的焦油当量和增烟剂含量之间可以近似拟合二次函数关系，即：焦油当量≈5.75－47.143×(增烟剂含量－24.32％) 2。
其中，5.75可以定义为该增烟剂的极限增烟焦油当量为T limit，47.143可以定义为该增烟剂的增烟系数为S，24.32％可以定义为该增烟剂的极限增烟焦油当量所对应的增烟剂含量为M limit。
除了上述实验所采用的烟丝和增烟剂，烟草薄片以及其它增烟剂也均呈现出上述规律，经仔细核对校验，在±5％的误差下均满足二次函数关系。由此，在卷烟产品设计和开发过程中，可以通过以下公式获得卷烟整体的焦油当量，一方面可以便于在卷烟研制过程中计算烟草薄片和烟丝所需添加的增烟剂含量，另一方面可以在卷烟产品包装上进行焦油当量标识，便于消费者选择所需烟雾产生量的卷烟产品。
所述经增烟处理的低危害卷烟的焦油目标当量为T target·mg/支，
所述经增烟处理的烟草薄片占所述气溶胶生成基质的质量百分比为M sheet，

T target＝M sheet×(T sheet+T limit1－S 1×(M limit1－M smoke1) 2)+M tobacco×(T tobacco+T limit2－S 2×(M limit2－M smoke2) 2)
的关系。
实施例15：卷烟焦油含量/当量和危害性指数实验
为进一步验证经增烟处理的低危害卷烟在增加焦油当量的同时，并未增加危害性，按实施例8方法制造增烟剂丁四醇含量分别占10％和20％的2种经增烟处理的低危害卷烟，并与市售传统烟七匹狼(纯典)、娇子(X玫瑰)、七匹狼(纯翠)一起测量焦油含量/当量和危害性H值。
表6 卷烟焦油含量/当量和危害性指数：
牌号 盒标卷烟 实测焦油含量/当量 实测危害性指数H值
实施例10％ / 当量4.8 2.21
实施例20％ / 当量5.6 2.18
七匹狼(纯典) 5 含量4.8 3.48
娇子(X玫瑰) 6 含量5.2 4.64
七匹狼(纯翠) 6 含量5.6 5.35
由表6可见，证经增烟处理的低危害卷烟在增加焦油当量的同时，仍保持较低危害性。
实施例16：红外遮光率实验三
选用实施例3的方法制造经增烟处理的烟丝，其中选用的其中选用的传统烟丝为3mg中南海烟支里吹出的烟丝，喷洒的增烟剂溶液为50％丁四醇的水溶液、50％戊五醇的水溶液、50％己六醇的水溶液，分别调整增烟剂溶液用量，依次制得丁四醇含量占最终干燥后的经增烟处理的烟丝质量百分比为15％、戊五醇含量占最终干燥后的经增烟处理的烟丝质量百分比为15％、己六醇含量占最终干燥后的经增烟处理的烟丝质量百分比为15％的3种经增烟处理的烟丝。
按实施例6方法将上述烟丝制造传统低危害卷烟、丁四醇含量占15％、戊五醇含量占15％、己六醇含量占15％的经增烟处理的低危害卷烟这4款样品，分别在吸烟机上按照加拿大深度抽吸模式(抽吸时间设 定为3秒)，采用加热器具的低温档(200℃)加热抽吸的方式测定的红外遮光率，数值越大代表烟雾浓度越高。
表7 不同卷烟红外遮光率：
红外遮光率/％ 传统低危害卷烟 含15％丁四醇 含15％戊五醇 含15％己六醇
第一口 0 32 46 40
第二口 0 35 49 43
第三口 3 36 49 48
第四口 8 36 55 49
第五口 10 39 55 52
第六口 10 40 54 52
从表7可以看出，未经增烟处理的传统低危害卷烟在加热烟具加热过程中几乎无法释放烟雾，而经增烟处理的低危害卷烟则能有效释放烟雾，且每口烟雾量也较为均匀。
除了上述丁四醇、戊五醇和已六醇外，各类丁三醇、戊三醇、戊四醇、已三醇、已四醇、已五醇、庚四醇、庚五醇、庚六醇、庚七醇等糖类、糖醇类多元醇物质均表现出增烟效果。此外，调节增烟剂占最终干燥后的经增烟处理的烟丝质量百分比为5％～25％也均出现明显增烟效果。
除上述包含烟丝的卷烟外，包含经丁四醇、戊五醇和己六醇等增烟剂进行增烟处理的烟草薄片也均表现出相对于未经增烟处理的烟草薄片更高的红外遮光率。
实施例17：总粒相物实验三
选用实施例3的方法制造经增烟处理的烟丝，其中选用的其中选用的传统烟丝为3mg中南海烟支里吹出的烟丝，喷洒的增烟剂溶液为50％丁四醇的水溶液、50％戊五醇的水溶液、50％己六醇的水溶液，分别调整增烟剂溶液用量，依次制得丁四醇含量占最终干燥后的经增烟处理的烟丝质量百分比为15％、戊五醇含量占最终干燥后的经增烟处理的烟丝质量百分比为15％、己六醇含量占最终干燥后的经增烟处理的烟丝质量百分比为15％的3种经增烟处理的烟丝。在传统烟丝上分别喷洒丙二醇和丙三醇，制得丙二醇和丙三醇含量分别占最终烟丝质量百分比为15％的两组对照组烟丝样品。
按照实施例6中的制造方法依次包卷成传统低危害卷烟，丁四醇含量占15％、戊五醇含量占15％、己六醇含量占15％的经增烟处理的低危害卷烟这4款样品，以及丙二醇含量占15％、丙三醇含量占15％的2款对照组样品。
在吸烟机上按照加拿大深度抽吸模式(抽吸时间设定为3秒)，采用加热器具在不同温度下加热抽吸，分别测定其总粒相物。
表8 不同卷烟加热产生的总粒相物：
Figure PCTCN2020132614-appb-000003
从表8可以看出，采用丁四醇、戊五醇和己六醇等增烟剂对低危害卷烟进行处理，由加热烟具在200℃下加热所产生的总粒相物即可以大于或等于14.0毫克，从而满足消费者对烟雾量的需求。
除上述包含烟丝的卷烟外，包含经丁四醇、戊五醇和己六醇等增烟剂进行增烟处理的烟草薄片的卷烟或是烟丝和烟草薄片混合卷烟也可以实现由加热烟具在200℃下加热所产生的总粒相物大于或等于14.0毫克。
实施例18：醛酮类有害物质实验
取用实施16中的卷烟样品，进一步在吸烟机上按照加拿大深度抽吸模式(抽吸时间设定为3秒)，采用加热器具在不同温度下加热抽吸，测定烟气中的羰基化合物释放量(单位为mg/支)。
表9 不同卷烟加热产生的醛酮类有害物质：
Figure PCTCN2020132614-appb-000004
Figure PCTCN2020132614-appb-000005
从表9可以看到，经增烟处理的低危害卷烟在200℃下加热时，所产生醛酮类有害物质明显低于在240℃下加热。
除上述包含烟丝的卷烟外，包含经丁四醇、戊五醇和己六醇等增烟剂进行增烟处理的烟草薄片的卷烟在200℃下加热时，所产生醛酮类有害物质也明显低于在240℃下加热。
实施例19：感官实验
根据实施例1的方法制造经增烟处理的烟草薄片，其中选用的传统烟草薄片浆料即为制造白沙(精品)的烟草薄片浆料，其中混入适量丁四醇作为增烟剂，制得丁四醇含量占最终干燥后的经增烟处理的烟草薄片质量百分比为15％的经增烟处理的烟草薄片。
根据实施例3的方法制造经增烟处理的烟丝，其中选用的传统烟丝为焦油3mg中南海烟支里吹出的烟丝，喷洒的增烟剂溶液为50％丁四醇的水溶液，调整增烟剂溶液用量，依次制得丁四醇含量占最终干燥后的经增烟处理的烟丝质量百分比为15％的经增烟处理的烟丝。
将上述烟草薄片和烟丝按表10比例混合并制成卷烟，由评烟师分别采用点燃抽吸和采用加热器具加热抽吸的方式，按照GB5606.4-2005及中式卷烟感官评价方法进行感官评吸。
