福州茉莉花茶窨制次数与香气成分的关联分析

Abstract

Abstract: In this study, Fuzhou jasmine tea with different scenting times was taken to determine relative contents of aroma components by gas chromatography mass spectrometry. Based on jasmine tea flavor (JTF) index, the quality of jasmine tea was evaluated completely. The results show that the relative contents and types of aroma components improved gradually with the increasing of scenting times from one to five and one jacquard, and 77 aroma components were detected finally. The quality of five-scenting jasmine tea was significantly better than four-scenting jasmine tea. Although, the quality of five-scenting jasmine tea was less than that of jasmine tea scented for five times and one jacquard, there was no significant difference. Therefore, five scenting jasmine tea was the best comprehensively. This study provided a reference for aerosol optimizing and processing of jasmine tea.

Key words: jasmine tea, aroma components, GC-MS, scenting times, JTF index
