Abstract
The stalk of *Allium fistulosum* is a rich source of dietary fiber, but its strong allicin odor hinders its application. This study compares various allicin removal methods, optimizing allicin extraction with 20 min water incubation and 75% ethanol extraction. Blanching at 100 °C proved most effective (73.3% allicin clearance), surpassing other physical (freezing) and chemical (tea polyphenols, citric acid) methods. This makes high-temperature blanching the most efficient approach for producing allicin-free dietary fiber from *Allium fistulosum* stalks.
