[Study on eliminating sodium nitrite and blocking nitrosamine synthesis by anthocyanin from skin of Alpinia galanga].
This study was performed to determine the ability of eliminating sodium nitrite and blocking nitrosamine synthesis by anthocyanin from the skin of Alpinia galanga. purified by macroporous resin. The test was conducted under the condition of the simulated human gastric juice (pH 3.0, 37 degrees C) with VitC as positive control. The results showed that the max capability of eliminating sodium nitrite was 87.14%, which is 1.6 times sronger than that of VitC, and the max capability of blocking nitrosamine synthesis was 97.82%, which is 8 times sronger than that of VitC.
