Effects of Different Fixatives on Fidelity and Slow-release of Huangjingui Tea Essential Oil Aroma
摘要
Abstract
An optimized and improved SDE method was carried out to get tea essential oil of high fidelity and the optimum condition was 2 h extraction of 25 g tea by continuous hot flowing steam. The effects of fixatives (diethyl phthalate, benzyl benzoate and vanillin) on this tea essential oil and their roles on the performance of aroma slow-release in tea essential oil were also studied by GC/MS and olfactory evaluation. The results showed that the persistence of fragrance was improved by all 3 fixatives. Among these, tea essential oil with diethyl phthalate showed highest fidelity of original odor type, indicating diethyl phthalate could be applied to manufacture tea aroma standard reference. Vanillin showed the best performance for aroma slow-release but the lowest fidelity. Benzyl benzoate had excellent coordinate ability and showed good performance for both fidelity and persistence which can be applied to develop tea fragrances. This study provided new ideas for fidelity and slow-release of tea essential oil. Meanwhile, the theoretical and practical foundation was established for hypostatization of tea olfactory term and innovation of tea fragrance and other field of tea industry.关键词
