摘要
【研究目的】为明确云南与津巴布韦烤烟在致香物质方面的差距,指导云南部分替代进口烤烟的研究和生产,提高烟叶质量,特进行此项试验。【方法】采用比色法测定了烟叶多酚总量,索式提取法测定石油醚提取物,硫酸甲酯、三氯甲烷萃取法测定多元酸和高级脂肪酸,水蒸汽-二氯甲烷同时蒸馏萃取、GC/MS-内标定量检测挥发性香气物质;并分类分析比较了云南与津巴布韦烤烟的多酚总量、石油醚提取物、多元酸、高级脂肪酸及挥发性香气物质等烟草致香物质含量的差异。【结果】结果表明云南烤烟各部位烟叶的石油醚提取物、芳香氨基酸降解的香气物质超过津巴布韦烤烟,多酚、高级脂肪酸则低于津巴布韦烤烟;上部烟叶的西柏烷类香气物质高于津巴布韦烤烟,多元酸、类胡萝卜素降解的香气物质、梅拉德反应的香气物质则低于津巴布韦烤烟;中部和下部烟叶的多元酸、类胡萝卜素降解的香气物质、梅拉德反应的香气物质高于津巴布韦烤烟,而西柏烷类香气物质则低于津巴布韦烤烟。云南与津巴布韦烤烟在致香物质方面的差距,主要表现在上部烟叶的柠檬酸、油酸、巨豆三烯酮、金合欢基丙酮、β-二氢大马酮、二氢猕猴桃内酯、糠醇、糠醛等致香物质含量低于津巴布韦烟叶。【结论】云南与津巴布韦烤烟的致香物质差异比较明显,上部烟叶致香物质含量明显不如津巴布韦。
[OBJECTIVE]In order to realize the difference in the aroma of flue-cured tobacco between Yunnan and Zimbabwe, guide for the study and production of partial substitution for import flue-cured tobacco in Yunnan, and improve of tobacco quality, the test was in progress. [METHOD]The content of polyphenols, petrol ether extract, polytomie acid and higher fatty acid, and the volatile aroma of flue-cured tobacco in Yunnan partial substitution for import plant areas of China was determined by eolorimetry, classical soxhlet extraction, sulfate methylization, GC-MS combined with simultaneous distillation and solvent extraction, respectively. And these results were analyzed and compared with that of Zimbabwe systematically. [RESULTS]Results showed that the content of petrol ether extract and degradation aromatic products from aromatic amino acid of the leaves at different stalk positions was more than that of Zimbabwe; but the content of polyphenols and higher fatty acid was lower than that of Zimbabwe. The content of eembranoid aroma in the upper leaves of Yunnan was more than that of Zimbabwe; but the content of polytomie acid, degradation aromatic products from earotenoids and Maillard reaction products was lower than that of Zimbabwe. The content of polytomie acid, degradation aromatic products from earotenoids and Maillard reaction products in the central and lower leaves of Yunnan was more than that of Zimbabwe; but the content of cembranoid aroma was lower than that of Zimbabwe. Devious difference of aroma of flue-cured tobacco between Yunnan and Zimbabwe exist in upper leaves, in particular the volatile aroma such as megastigmatrienone, 5,9,13-pentadecatrien-2-one, 6,10,14-trimethyl, 3-buten-1-one, 4-[2,6,6-trimethyl-1 (or 2) -cyclohexen-1-yl], 3-furanmethanol, furfural, 2 (4H)-benzofuranone, and 5,6,7,7a-tetrahydro-4,4,Tatrimethyl, the nonvolatile aroma such as citric and oleic acid.[CONCLUSION]There was significant in the aroma of flue-cured tobacco between Yunnan and Zimbabwe, and the contene of aroma of upper leaves in Yunnna was less than that of Zimbabwe.
