[背景和目的]针对加热卷烟用再造烟叶吸湿性过强的问题,克服其在制丝、卷包以及贮存过程中易吸潮的缺陷,确保其耐加工性以及感官质量的稳定性.[方法]以壳聚糖、石蜡、黄原胶为配方组分,在单因素实验的基础上,采用响应面-主成分分析法优化膜材料配方,开发出具有适中疏水性的膜材料涂布液,用于再造烟叶表面疏水改性.[结果]优化得到膜材料配方为:壳聚糖、石蜡和黄原胶的涂布量分别为0.6g/m2、1.5 g/m2、1.6g/m2,在此条件下制得改性再造烟叶的接触角87.542°、吸湿率10.98％、放湿率2.16％、感官质量得分87分.相比于传统再造烟叶,改性后再造烟叶的吸湿率和放湿率均显著降低,感官质量基本保持,抗张强度有所提升,再造烟叶的综合性能得到明显改善.
Targeting the problem of high moisture absorption characteristic of reconstituted tobacco used for heated cigarette,aiming at overcoming the defects of easy moisture absorption in cigarette making,packaging and storage,ensuring processing resistance and stability of sensory quality,chitosan,paraffin and xanthan gum were used as the formulation components to develop one membrane material coating with moderate hydrophobicity used in the surface hydrophobic modification of reconstituted tobacco.Based on the single factor experimental,the response surface and principal component analysis method were carried out to optimize the coating formula.The results indicated that:the optimized coating mass of chitosan,paraffin and xanthan gum were 0.6g/m2,1.5 g/m2,1.6 g/m2,respectively.Under this condition,the contact angle,moisture absorption rate,moisture release rate and sensory score of modified reconstituted tobacco were 87.542°,10.98％,2.16％,and 87,respectively.compared to the conventional sample,the moisture absorption rate and the release rate of modified reconstituted tobacco decreased significantly,while the sensory quality remained and the tensile strength rose greatly,indicating that the comprehensive characteristic was enhanced significantly.
