Key Points

The aim is to investigate how varying protein content in raw barley grains impacts the flavor profile of roasted barley tea.
Cultivated two barley varieties under four fertilization conditions over two years.
Obtained barley with different protein contents.
Roasted the barley and analyzed the resulting tea for volatile compounds using GC-MS.
Measured the concentration of 21 aromatic components in the brewed tea.
Positive correlation between protein content and levels of pyrazines and thiazoles in tea.
Negative correlation between protein content and the concentration of furfural.
Higher protein content leads to a stronger roasted, nutty aroma; lower content results in a sweeter, almond-like scent.

Examines how different protein levels in barley affect flavor in roasted barley tea, indicating key aroma changes.
