Scavenging capability of spices to sodium nitrite
The scavenging capability of Chinese prickly ash,anise or white pepper to sodium nitrite was studied,with the effecting factors such as the dose of extract of the spice,extract solvent and the reaction time.Results showed that 60% ethanol was suitable for extracting Chinese prickly ash or anise,while anhydrous ethanol was appropriate for white pepper.With the increasing dose of the extract of the spice,the scavenging rate of sodium nitrite increased and then decreased.The reaction time of 10 min was enough.Besides,the mixture of Chinese prickly ash and anise at the ratio of 1:2(w/w) showed synergistic action.
