摘要
以‘古巴7号’雪茄烟中部叶为材料,测定3种编烟密度(30、35和40片/m)下雪茄烟叶的物理特性、化学成分和中性致香物质含量。结果表明:随着编烟密度的增加,雪茄烟叶单叶质量、叶片厚度和叶质重逐渐降低,含梗率、拉力和平衡含水率烟碱含量则逐渐增加;当编烟密度为35片/m时,蛋白质含量最低,总糖和还原糖含量最高;当编烟密度从30片/m增加至35片/m时,烟叶新植二烯含量逐渐升高,当编烟密度从35片/m提高至40片/m时,其含量降低45.74%,导致烟叶的中性致香物质总量也降低;类西柏烷类降解产物也呈现相同的变化趋势。综上,编烟密度为35片/m时,雪茄烟叶的物理特性较好,化学成分较协调,中性致香物质含量较高,有利于雪茄烟叶品质的形成。
The physical characteristics,chemical components,and neutral aroma components of cigar tobacco leaves were measured under three different cigarette weaving densities(30,35,and 40 pieces/m)using Cuba No.7 central leaf as the material.The results showed that with the increase of weaving density,the single leaf mass,leaf thickness,and leaf mass weight of cigar tobacco gradually decreased,while the stem content,tensile force,and equilibrium moisture content gradually increased.When the density of woven tobacco was 35 pieces/m,the protein content was the lowest,while the total sugar and reducing sugar were the highest.The nicotine content increased with the in crease of woven tobacco density.When the density of woven tobacco increased from 30 pieces/meter to 35 pieces/m,the content of neophytadiene in tobacco leaves gradually increased.When the density of woven tobacco increased from 35 pieces/m to 40 pieces/m,neophytadiene content decreased by 45.74%,resulting in a decrease in the total amount of neutral aroma compounds in tobacco leaves,and a similar trend in the degradation products of cembranenoid.In summary,when the weaving density is 35 pieces/m,the physical properties of cigar tobacco leaves are better,the chemical components are more coordinated,and the content of neutral aroma substances is higher,which is conducive to the formation of cigar tobacco quality.
