Several general purpose calorimeters were found which under the proper sample presentation conditions could successfully be used for orange juice color measurement in place of special purpose Hunterlab citrus calorimeter. Correlations of better than 0.98 were achieved for multiple regression equations for Agtron abridged spectrophotometer, sphere collector calorimeters, and 0.45° viewing calorimeters as compared with the citrus calorimeter color scores for 101 samples. This paper presents the methods used, regression equations, and possible reasons why certain sample presentation methods were more successful than others.
