摘 要: | [目的]采用静态微波真空干燥技术制备烟草内源性固体香料。[方法]对烟草提取物进行静态微波真空干燥,通过对其挥发性成分的分析,以及与不同方法干燥后所得的样品进行比较。[结果]经微波真空干燥后的样品,其成分大部分与干燥前的样品一致,产品品质稳定;对样品进行3种干燥处理,静态微波真空干燥对于烟草重要香味物质的保留更为完整,烟碱含量最低,为56.7%,β-大马酮含量为0.68%,比喷雾干燥(0.25%)和冷冻干燥(0.17%)均有较大提高,分别提升了1.72倍和3.00倍,是较优的干燥方法;三角评吸结果显示,静态微波真空干燥后的样品与原提取物无差异。[结论]该技术运用于烟用香料,不仅不会改变烟草提取物的化学成分,还能延长产品存储时间,为开发高纯度烟用香精香料提供广阔的空间和应用价值。

Abstract: | Objective] The aim was to prepare tobacco endogenous solid flavor by vacuum microwave drying technology.[Method] Static mi-crowave vacuum drying was conducted on tobacco extracts, volatile components were analyzed, samples obtained by different drying methods were compared.[Result] The results showed that after vacuum static microwave drying, most of its components were consistent with the sample before drying, product quality remained stable;three drying methods were adopted to process the samples, static vacuum microwave drying could retain most complete tobacco important aroma, nicotine content was lowest as 56.7%,β-damascenone content was 0.68%, compared to spray drying (0.25%) and freeze-dried (0.17%) were greatly improved, which was raised 1.72 and 3.00 times.It was the optimum drying method;The re-sult of triangle smoking showed that the sample under the static vacuum microwave drying was no difference with the original extract.[ Conclu-sion] The technology used in tobacco flavor does not change chemical composition of tobacco extracts, but can extend the storage time of the product.It offers a wide range of space and value to develop the high purity tobacco flavors. |
