SUMMARY The carotenoids and sterols of lemon juice from various sources were measured. The average total carotenoid contents for reconstituted lemon juice concentrate and for fresh juice from coastal, desert, and Italian lemons were respectively 49, 50, 40, and 45 μg β‐carotene/l00 ml juice. The average respective sterol values were 8.28, 8.99, 9.10, and 8.46 mg β‐sitosterol/l00 ml juice. The major lemon juice sterol was β‐sitosterol. The correlation between citric acid, carotenoids, and sterols was too low to be useful in the multiple regression analysis equation for the prediction of citric acid.
