Abstract

AbstractCanned single‐strength grapefruit juice samples were collected biweekly from the main producing plant in Cuba during the 1980–81 to 1983–84 seasons. They were analyzed for °Brix, acid, naringin and limonin content and evaluated for sensory quality. Average values for each quality factor vary from season to season. Better sensory quality was found in samples with high Brix/acid ratio and lower bitter compounds content. No correlation relationship was found between Brix, Brix/acid ratio, naringin and limonin. The first 3 are the main quality factors related to grapefruit juice flavour.
