    [0001]一种复合酶制剂及将该复合酶制剂用于烟梗生产的工艺
    [0002]技术领域
    [0003]本发明涉及卷烟生产辅助剂及卷烟生产工艺,具体地说是指一种复合酶制剂及将该复合酶用于烟梗生产的工艺。
    [0004]背景技术
    [0005]全世界有11亿人吸烟,约占全世界人口的22%,而我国约有3.3亿烟民,占我国人口的25%,占世界吸烟人口的30%,其烟草产销量居全球之冠。因此,在我国40个在的工业行业中,烟草加工业的盈利水平名列榜首,净资产回报率达27.69%。
    [0006]烟梗或梗丝是卷烟配方烟丝中的重要组成成分之一,加工良好的梗丝不仅能增加烟丝的填充值,降低卷烟单耗,提高卷烟的燃烧性与烟气的透发性,而且还可降低烟气焦油量,提高卷烟的色香味,同时,烟梗也是烟草薄片的重要原料。因此,卷烟企业都非常重视对烟梗加工技术的研究。
    [0007]从已有的研究结果表明,梗丝香味不足,是因为影响香烟风味的一些重要成分如β苯乙醇、β-大马酮、叶绿酮等致香成分含量很低,而糠醛、苯乙醛等含量却很高,木质气重。为了克服这些问题,目前国内烟梗制丝技术只是对烟梗的物理性状进行改变,并利用添加香料对其刺激性、杂气进行掩盖,而烟梗的化学成份并未改变。因此,利用现有技术降低木质杂气和刺激性的程度非常有限。就烟梗本身而言,其物理特性和化学组分与烟叶存在本质的差异,烟梗的主要成份是纤维素、半纤维素、木质素、果胶质,同时含有少量的酯类、淀粉和蛋白质。其酯类燃烧易增加焦油含量;纤维素、木质素燃烧不充分时产生易引起吸烟者呛咳的刺激性气味;木质素和果胶燃烧可产生有毒的甲醇等物质,并带有较大的木质杂气;含氮化合物燃烧易产生自由基和特有亚硝胺;木质素燃烧易产生3,4苯并芘等。
    [0008]发明内容
    [0009]本发明提供一种复合酶制剂及将该复合酶用于烟梗生产的工艺,其主要目的在于通过改变烟梗的化学成分,降低现有烟梗在燃烧过程中产生的焦油、刺激性气味及其它有毒、有害的物质。
    [0010]本发明采用如下技术方案:一种复合酶制剂,由木质素酶、果胶酶、纤维素酶、淀粉酶、蛋白酶及酯酶中的二种或二种以上及水组成,其中,各组分在按上述任一组合配制成的复合酶制剂中的重量百分比含量为:木质素酶0.001%-0.5%、果胶酶0.001%-0.5%、纤维素酶0.001%-0.5%、淀粉酶0.001%-0.5%、蛋白酶0.001%-0.5%、酯酶0.001%-0.5%,余量为水。
    [0011]上述复合酶制剂的优选取组成成分及重量百分比含量为:木质素酶0.02%、果胶酶0.02%、纤维素酶0.02%、淀粉酶0.02%、蛋白酶0.02%、酯酶0.02%,余量为水。
    [0012]上述复合酶制剂的优选取组成成分及重量百分比含量为:果胶酶0.03%、纤维素酶0.05%、木质素酶0.02%,余量为水。
    [0013]将上述复合酶制剂应用于烟梗生产的工艺包括如下步骤:1)将所述各种酶类和水进行混合,水温控制在45℃±9℃,PH值控制在4.4±1.0,搅拌均匀形成复合酶液;2)将烟梗浸入上述复合酶液中7-60秒,然后在30-40℃条件下贮存3-20小时;3)在大于90℃的温度下对烟梗进行蒸梗灭酶,促进呈色、呈香、呈味反应。
    [0014]本发明可使烟梗中的梗蜡、油脂、果胶质、淀粉、蛋白质、纤维素和木质素部分降解,在蒸梗时,不仅可以有效灭酶,同时可促进降解物间的美拉德反应和酯化反应等。故可使梗丝色泽更加明快、手感松软、富有弹性,更加符合卷制的要求。再者,由于烟梗的结构和组成发生了变化,理化性质也随之变化,进而达到降低香烟的木质气和刺激性气味、改善吸味、提高内在质量与外在品质的目的。本发明对制梗丝工艺改良、低档次烟叶处理、烟草薄片处理、烟叶陈化以及降焦减害、促进烟草工业的可持续发展、改善烟民的健康水平都有重要而深远的意义。
    [0015]具体实施例
    [0016]本发明的具体实施例一,按照以下重量百分比将各组分混合:木质素酶0.001%、果胶酶0.001%、纤维素酶0.001%、淀粉酶0.001%、蛋白酶0.001%、酯酶0.001%、水99.994%,将水温控制在45℃±5℃,PH值控制在4.4±0.3,搅拌均匀形成复合酶液;将烟梗浸入上述复合酶液中7-30秒,然后在30-40℃条件下贮存3-5小时;最后在大于90℃的温度下对烟梗进行蒸梗灭酶,促进呈色、呈香、呈味反应。
    [0017]在烟梗中加入复合酶后,经多次反复试验证明,通过酶促反应,增加了氨基化合物,如氨基酸,和羰基化合物,如可溶性糖,高级饱和一元醇和高级脂肪酸等,使之有效地增加美拉德反应和各种酯化反应等的反应底物。
    [0018]在本实施例中,结合并利用了卷烟企业制梗丝的工艺设备等技术条件,有针对性地研究筛配具有生物活性的多功能复合酶,通过加酶后的洗梗液处理,对烟梗燃烧时产生的有害组分适量降解或修饰,并借助高温蒸梗灭酶和促进降解物或修饰物之间的化学反应,达到调节烟气酸碱度、降低烟气刺激性、减少木质杂气、提高梗丝内在质量和外在品质的目的。
    [0019]由于烟梗的化学结构和组成发生了变化,梗丝的色香味也随之变化。评吸结果表明,在评吸指标中,经复合酶处理后的梗丝各项评吸指标,如香气质、香气量、余味等均显著高于对照产品,尤其是杂气和刺激性均大幅度下降,杂气下降达25%-60%,刺激性下降达20%-50%。
    [0020]本发明的实施例二,与实施例一的区别在于其复合酶液中各组分的重量百分比含量不同,其各组分分别为:木质素酶0.02%、果胶酶0.02%、纤维素酶0.02%、淀粉酶0.02%、蛋白酶0.02%、酯酶0.02%,、水99.88%。其工艺过程与实施例一相同。
    [0021]本发明的实施例三,与实施例一的区别在于其复合酶液中各组分的重量百分比含量不同,其各组分分别为:木质素酶0.5%、果胶酶0.5%、纤维素酶0.5%、淀粉酶0.5%、蛋白酶0.5%、酯酶0.5%,、水97%。其工艺过程与实施例一相同。
    [0022]本发明的实施例四,与实施例一的区别在于其复合酶液中各组分及其重量百分比含量不同,其各组分分别为:果胶酶0.03%、纤维素酶0.05%、木质素酶0.02%、水99.9%。其工艺过程与实施例一相同。
    [0023]上述各种酶类的选择及其含量的确定,可根据所选用的烟梗的具体情况确定。
    [0024]上述仅为本发明的几个具体实施例,但本发明的设计构思并不局限于此,凡利用此构思对本发明进行非实质性的改动,均应属于侵犯本发明保护范围的行为。
