California navel orange juice, two-stage pulpwash and concentrated orange juice obtained from a commercial processing plant during the 1979–80 processing season were analyzed by chemical, physical and microbiological methods. Statistically significant differences (P < 0.01) were found between single-strength orange juice and pulpwash in the concentration of nitrate, sulfate, phenolics, carbohydrates, protein, pectin, UV/VIS absorption characteristics, minerals and carotenes. Seasonal variations were found in carbohydrates, organic acids, minerals, microbiological data, UV/VIS absorption characteristics, carotenoids, protein and phenolics. This report outlines methods of analysis, summarizes analytical results and discusses application of these findings to the detection of pulpwash adulteration of orange juice.
