WebOct 8, 2024 · While oxidation turns buds gold, it darkens mature tea leaves almost to black. The source of the darker color is chlorophyll, which degrades during oxidation to murky brown pheophytins and pheophorbides. Buds contain very little chlorophyll, and what little they have dissolves during withering. WebThe chlorophyll, pheophytin, and their proportions are critical factors to evaluate the sensory quality of green tea. This research aims to establish an effective method to determine the quantification of chlorophyll and pheophytin in green tea, based on Fourier transform infrared (FT–IR) spectroscopy. First, five brands of tea were collected for spectral … WebColor measurements indicated a difference of 4.1 units between the controls and the samples processed at 280°F, and 11.6 units between the controls and the samples … blackwell hvac pensacola
