Description

一种盐的水溶液作为水合性烟梗保润剂的用途
技术领域
本发明涉及烟草领域, 特别是涉及一种盐的水溶液作为水合性烟梗保润剂的用途。 背景技术
在烟草加工过程中, 添加保润剂对于改善烟丝的耐加工性、 运输、 仓贮和吸食的感官舒 适度和刺激性都有重要的作用。 根据保润剂的作用机理, 卷烟的物理保润剂可分为三类: ( 1 ) 吸湿性保润剂, 这类物质有较强吸水性, 其作用是吸收水分并保存于卷烟中, 主要成 分包括多元醇 (如甘油、 丙二醇、 山梨醇等)、 烟草本身或其它植物所含的亲水基质 (如碳 水化合物、 蛋白质、 果胶等), 如中国专利 "新型烟草保润剂"(申请号 98113287.1 ) 报道的 醛糖及其衍生物配方, 中国专利 "魔芋保润剂及其在卷烟中的应用 " (申请号 CN200910061990.9) 报道的魔芋提取物; (2) 封阻性保润剂, 主要成分为油脂类, 其作用是 在烟丝表面形成封闭屏障, 防止内部水分的蒸发散失, 包括石蜡油、 植物油、 天然油性萃取 物等, 如中国专利 "蜡脂类烟草保润剂及其制备方法"(申请号 CN 101658323) 报道的蜡脂 类烟草保润剂, 中国专利 "烟用保润剂"(申请号 CN201010142981.5) 报道的多碳脂肪醇以 及多碳脂肪酸配方; (3) 水合性保润剂, 可与水发生溶剂化作用, 主要是一些如镁盐等的金 属离子类, 但这类水合性盐大多在水中不溶, 难以应用, 且有关这类保润剂的报道极少。
烟叶为疏松的多孔材料, 吸收及散失水分的潜力是较高的。 烟梗是烟叶的粗硬叶脉, 多 孔性和孔隙度显著高于烟叶, 平衡含水率也显著高于烟叶, 吸收水分的潜力更强, 然而这部 分水分很容易再丢掉, 其水分散失速度比烟叶更快, 实际上保润性能更差。
烟梗原料中果胶含量丰富, 且常与钙离子等结合。 通过添加可溶性无机或有机酸、 或其 金属盐水溶液, 可将果胶酸钙中的钙离子置换出来, 并转化生成水合性钙离子, 如草酸钙、 磷酸 (一或二) 氢钙、 柠檬酸钙、 乳酸钙等, 有效阻止烟丝内部水分散失, 有利于改善其保 润性能。 目前国内外鲜有采用水合性保润剂提高梗丝保润性能的报道。 发明内容

( 1 ) 所述水合性烟梗保润剂为一种可溶性或易溶性的无机或有机酸、 或其金属盐的水溶 液, 通过将烟梗细胞自身的钙离子置换出来而在孔道中生成不溶或微溶的水合型钙盐, 起到 保润的作用。
(2) 所述水合性烟梗保润剂与烟梗相容性稳定, 安全无毒害, 易于推广应用。
(3) 所述水合性烟梗保润剂制备工艺简单, 仅需将可溶性或易溶性的无机或有机酸、 或其 金属盐溶于去离子水得到溶液后即可直接用于生产 (在线设备可控温 10〜90QC)。 附图说明
