摘要
为研究瓜尔胶和羧甲基纤维素钠(CMC)及黄原胶和羟丙基甲基纤维素(HPMC)2种等比例复配胶黏剂在干法烟草薄片中的应用价值,对4种胶黏剂原料及其用于干法烟草薄片进行了热性能分析,并测试了干法烟草薄片的纵向抗张强度和热裂解性能。结果表明,4种胶黏剂原料在室温至350℃间的热质量损失时间与速率接近,4种胶黏剂原料或其糊化物在15~230℃较稳定;复配胶黏剂中各组分有良好的相容性,可提高烟草薄片的抗张强度;瓜尔胶和CMC等比例复配胶黏剂制备的干法烟草薄片具有烟碱释放量低(1.98%)、致香成分释放量高(4.04%)、刺激性或有毒成分释放量低(2.39%)和纵向抗张强度大(0.54kN/m)的优点。
In order to investigate the application of the 2 equal proportional compound adhesives of guar gum with CMC and xanthan gum with HPMC for the dry tobacco reconstituted tobacco,the 4 kinds of adhesive raw materials and the dry reconstituted tobacco were analyzed by TG and DSC,the longitudinal tensile strength and thermal cracking characteristics were also tested.The results showed that the duration and rate of thermal weight loss of the 4 kinds of adhesives were similar to each other within the room temperature to 350℃.The 4 kinds of ad⁃hesives or their pastes were stable from 15℃to 230℃.The components in the compound adhesive had good compatibility,which could im⁃prove the tensile strength of the reconstituted tobacco.The dry reconstituted tobacco prepared with guar gum and CMC in equal proportions had the advantages of low release of nicotine(1.98%),high release of aroma-causing ingredients(4.04%),low release of irritating or toxic ingredients(2.39%)and high longitudinal tensile strength(0.54 kN/m).
