Abstract

Stable carbon isotope ratio analysis (SCIRA) was used to determine the authenticity of commercial Australian orange juices. Thirty-five samples of Valencia ('13C values from '23.8 to '24.7 ppt) and eight samples of Navel juices ('13C values from '24.1 to '24.5 ppt) of known origin were used to establish a decision level before analysis. No significant seasonal variations in 13C/12C ratio were observed. Variations in combustion temperature in the method were also found to be insignificant.
