About grapefruit and its juice cells
Grapefruit, Citrus × paradisi, is a large citrus fruit valued for its characteristic balance of sweetness, acidity, aromatic citrus flavor and natural bitterness. Commercial fruit is broadly grouped into white, pink and red-fleshed types, with cultivars such as Marsh, Ruby Red and Star Ruby representing different color and sensory profiles.
The fruit consists of an aromatic peel, white albedo, segment membranes, seeds where present and numerous juice-filled vesicles inside each segment. These elongated juice sacs contain most of the edible juice and form the natural pulp consumers recognize in grapefruit beverages.
White grapefruit typically provides a pale yellow pulp, while pink and red cultivars can range from light pink to deeper ruby tones. Variety, maturity, growing region and crop conditions influence color, sweetness, acidity, bitterness and aroma.
