Abstract

Orthogonal test of L16(45) was designed to study the effect of changeable baking temperature on aroma quality and components of Dangui Oolong tea in southern Fujian. Results showed that treatment of A4B1C4D2E3 got teas with high aroma quality. Results also showed that baking process of Dangui Oolong tea could be divided in three steps, with the optimal process of 120℃-20βmin, 90℃-130βmin, 120℃-30βmin. Totally 64 kinds of aroma components were identified, including alcohols, aldehydes, nitrogenous compounds, hydrocarbons. The main components were trans-nerolidol, alpha-farnesene, benzeneacetaldehyde, indole, phenylethyl alcohol, phenylethyl-2-methylbutanoate, benzyl nitrile, dihydrolinalool, benzyl alcohol, linalool and styrene, which totally accounted for nearly 90%. The main factors influencing aroma quality of Dangui Oolong tea were baking temperature and time in the third step, followed by the first and the second steps. High temperature could improve tea aroma. These findings laid the foundation for further researches on baking technology of Dangui Oolong tea.
