An analysis of the limonin and naringin content of 6685 grapefruit juice samples (representing approximately 6% of all grapefruit harvested) collected from three Florida State Test Houses showed that there were statistically significant differences between the Test Houses.  There also was a statistically significant difference in the concentration of these compounds in the juice from the different cultivars of fruit sampled.  Average limonin and naringin concentrations in the juice remained fairly constant through the beginning of the season until a freeze occurred in early 1981.  Juice obtained from fruit harvested after this freeze contained decreasing amounts of limonin and increasing …
