This study examined how large-leaf yellow tea develops its distinctive fried rice-like aroma during processing. Researchers identified 178 different volatile compounds throughout eight processing stages using advanced analytical techniques. The full fire roasting step was found to be most important for creating the final roasted and nutty flavors, generating 30 new nitrogen-containing compounds. An electronic nose device successfully tracked these aroma changes in real-time, suggesting it could be used for quality control in tea production.
