Purification and Gas Chromatography–Combustion–Isotope Ratio Mass Spectrometry of Aroma Compounds from Green Tea Products and Comparison to Bulk Analysis

A method for carbon isotope ratio (δ13C) analysis was developed for compound-specific isotope analysis of tea volatiles, and the values were compared with the δ13C value from bulk isotope analyses. The δ13C value of 2-phenylethanol liberated via enzymatic hydrolysis of the 2-phenylethyl β-primeveros...
