    Abstract: The present invention relates to a method for preparation of a fermented Allium tuberosum composition which is obtained by inoculating and fermenting Allium tuberosum with yeast to generate nitrite ions and adding an anthocyanin to stabilize the nitrite ions, and to the fermented Allium tuberosum composition, whereby when ingested into the body, the natural nitrite ions are converted into nitric oxide to induce various biological activities such as hypotension, immunopotentiation, improved blood circulation, and the like. An anthocyanin can be obtained in the form of an extract from aronia, purple corn, black rice, berries such as blueberries and so forth, black bean, and the like and can improve the thermal stability of nitrite ions. Provided are thus a method for preparing a nitrite ion-stabilized, fermented Allium tuberosum liquid by adding an anthocyanin to a fermented Allium tuberosum liquid and a composition thereof.
