摘　　要：为最大程度保留烟草香料中挥发性致香成分,采用正渗透和减压蒸发方式浓缩制备了可溶物固含量为55%的红花大金元烟叶水提浸膏,从致香成分、常规化学成分、理化指标及感官质量等4个方面对浸膏的品质进行了分析。结果表明:①两种浸膏的致香物质组成基本一致,致香成分含量达到极显著差异(p<0.0001),正渗透浓缩较蒸发浓缩的浸膏致香物质总量增加89.17%;β-大马酮增幅超过50%,β-紫罗兰酮、二氢猕猴桃内酯、芳樟醇增幅均超过100%;②两种浸膏的总糖、还原糖、总氮、氯离子和钾离子指标达到极显著性差异(p<0.0001),其中,正渗透浓缩浸膏的氯离子含量增加,钾离子下降;③正渗透浓缩浸膏的酸值、相对密度、折光指数分别较蒸发浓缩浸膏极显著下降了3.24%、1.44%和0.28%(p<0.0001),而挥发性成分总量极显著提高1.17%(p<0.0001);④正渗透浓缩的浸膏感官质量总分显著高于蒸发浓缩(p<0.05),感官评价结果更优。因此,正渗透浓缩技术可为烟草香料和再造烟叶涂布料的提质提供技术支撑。In order to maximize the retention of volatile aromatic components in tobacco flavor,water extracts of Honghuadajinyuan tobacco were prepared by forward osmosis and vacuum evaporation concentration with 55%soluble solid content.The quality of the extracts was analyzed from four aspects:aromatic components,conventional chemical components,physical and chemical indexes and sensory quality.The results showed that:(1)The composition of the two extractums was basically the same,and the content of the aroma components reached a very significant difference(p<0.0001).The total amount of aroma substances in the forward osmosis concentration was increased by 89.17%compared with that in the evaporation concentration.β-macarone increased by more than 50%,β-ionone,dihydrokiwi lactone and linalor increased by more than 100%;(2)The indexes of total sugar,reducing sugar,total nitrogen,chloride ion and potassium ion of the conventional chemical components of the two extractum reached extremely significant differences(p<0.0001).Among them,the chloride ion content of the forward osmosis concentrated extractum increases while potassium ion decreases;(3)The acid value,relative density and refractive index of forward osmotic concentrated extract were significantly decreased by 3.24%,1.44%and 0.28%(p<0.0001)compared with that of evaporative concentrated extract,while the total volatile components were significantly increased by 1.17%(p<0.0001);(4)The total sensory quality score of forward osmosis concentration was significantly higher than that of evaporation concentration(p<0.05),and the sensory evaluation result was better.Forward osmosis concentration technology can provide technical support for improving the quality of tobacco flavor and remanufactured tobacco coating material.
