摘要
为分析雪茄烟叶精油的成分及评价其作用,采用亚临界萃取、分子蒸馏技术,制备了雪茄烟叶精油,明确了不同蒸馏温度下精油各类成分的富集效果;采用GC/MS法分析了精油主要成分,结合卷烟感官作用评价,进一步验证了精油中各类成分质量分数对卷烟感官质量的影响,并通过相关分析探讨了部分致香成分与感官评价指标的关系。结果表明:(1)60~80℃蒸馏温度下,可降低精油中烟碱、烷烃以及长链脂肪酸酯的质量分数,有效富集雪茄风格特征致香成分;(2)精油中香叶基丙酮、β-紫罗兰酮、巨豆三烯酮、二氢猕猴桃内酯、金合欢基丙酮、苯乙酸、乙酸、丙酸、二氢-β-紫罗兰酮、正己酸、6-甲基-5-庚烯-2-酮、罗汉柏烯和(E)-橙花叔醇等的质量分数与卷烟烟气的香气、综合味觉、木香和蜜甜香等指标呈显著或极显著正相关关系,因而,这些化合物可作为雪茄烟叶精油质量评价的主要指标。
In order to analyze the chemical components in the essential oil of cigar tobacco and to evaluate their effects,the essential oil of cigar tobacco was prepared by using subcritical extraction and molecular distillation technology.The enrichment effects of various components in the essential oil at different distillation temperatures were clarified.The main chemical components of the essential oil were analyzed by GC/MS,and the influences of mass fractions of various components in the essential oil on the sensory quality of cigarettes were further verified through sensory panel evaluation.The relationships between some aroma components and sensory evaluation indexes were studied via relevant analysis.The results showed that:1)At the distillation temperature of 60-80℃,the mass fractions of nicotine,alkanes and long-chain aliphatic esters were reduced,and the aroma components with cigar styles were effectively enriched.2)The mass fractions of geranyl acetone,β-ionone,megastigmatrienone,dihydroactinidiolide,farnesyl acetone,phenylacetic acid,acetic acid,propionic acid,dihydro-β-ionone,n-hexanoic acid,6-methyl-5-heptene-2-one,thujopsene and(E)-nerolidol in the essential oil significantly positively or extremely significantly positively correlated with the quality evaluation indexes of cigarettes,including aroma,comprehensive taste,woody and honeysweet scents.Therefore,these compounds could be used as the main indexes for evaluating the quality of essential oil of cigar tobacco.
