新型再造烟叶裹衣的制备和性能

Preparation and Properties of New Cigarette Wrapper Based on Reconstituted Tobacco Sheet

目的为替代天然雪茄外包皮,开发一种新型再造烟叶雪茄烟裹衣,重点改善再造烟叶裹衣色泽的稳定性。方法基于再造烟叶生产技术,以烟梗浆、漂白针叶木浆和漂白阔叶木浆制备新型再造烟叶裹衣,通过添加一定尺度的木质素改善裹衣的色泽稳定性。结果制备的再造烟叶裹衣抗张强度为1.13 kN/m,透气度为29.3 cm^(3)/(min·cm^(2)),伸长率为1.42%,阴燃速率为0.849 s/mm;木质素质量分数为4.0%时(以天然色素用量计),色差(ΔE=4.49,12h)与空白样品相比(ΔE=13.47,12h),色泽稳定性提高了66.7%;感官质量评价较好。结论开发的新型再造烟叶裹衣完全达到了再造烟叶裹衣对物理性能、燃烧特性和色泽稳定性要求(ΔE≤5.0,12 h内),同时满足再造烟叶感官质量的评价指标要求。

The work aims to develop a new reconstituted tobacco sheet used for cigar wrapper,and focus on improving the color stability of cigar wrapper from tobacco sheet to replace the natural cigar wrapper.Based on the production technology of reconstituted tobacco,a new cigarette wrapper based on reconstituted tobacco sheet was prepared with tobacco stem pulp,bleached softwood pulp and bleached hardwood pulp.Lignin with certain molecular weight was used to increase the color stability of natural pigments.The tensile strength of the reconstituted tobacco sheet was 1.13 kN/m.Its air permeability was 29.3 cm^(3)/(min·cm^(2)).Its elongation percentage was 1.42%.Its static combustibility rate was 0.849 s/mm.Its content of alkaline lignin was 4.0%(calculated in natural pigment).Its chromatic aberration was 4.49(ΔE=4.49,12 h).Its color stability was increased by 66.7%compared with that of the control sample(ΔE=13.47,12 h).Its sensory quality was good.The cigarette wrapper from reconstituted tobacco fully meets the requirements of physical properties,combustion characteristic and color stability(ΔE≤5.0,within 12 h),and meets the evaluation index of sensory quality for cigar wrapper.
