Zusammenfassung:The "popcorn"-like aroma was identified as 2-acetyl-1-pyrroline. Cooked Della white rice contained almost 300 ng 2-acetyl-1-pyrroline per g (dry weight) rice, while cooked Lemont white rice (nonaromatic cultivar) contained 4 ng per g (dry weight). Della white rice contained almost four times more 2-acetyl-1-pyrroline as the average (73 ppb) in two batches of Jasmine white rice imported from Thailand and comparably analyzed
