-"The fruit tastes like a sweet, mild grapefruit (believed to be a hybrid of Citrus maxima and the orange), although the typical pomelo is much larger than the grapefruit, and also has a much thicker rind. The pomelo has none, or very little, of the common grapefruit's bitterness, but the enveloping membranous material around the segments is bitter, considered inedible, and thus is usually discarded." \\+"The fruit tastes like a sweet, mild [[citrus_paradisi|grapefruit]]... , although the typical pomelo is much larger than the grapefruit, and also has a much thicker rind.

-Cold-pressed oils (CPO) of pummelo contained limonene (55.4-94.1%), γ-terpinene (0.1-9.3%), and myrcene (2.2-39.3%) as main components. Each kind of pummelo was found to contain nootkatone at a considerable level (0.04-0.95%) and it may be regarded as a key compound of pummelo aroma. \\+Cold-pressed oils (CPO) of pummelo varieties contained limonene (55.4-94.1%), γ-terpinene (0.1-9.3%), and myrcene (2.2-39.3%) as main components.

 +"γ-Terpinene was the second major component in 4 varieties, but only a minor component in the others... Multivariate analyses were applied to 37 kinds of citrus fruits including pummelos and other species. The pummelo was classified into 2 groups by cluster analysis, and into 3 groups by principal component analysis on the basis of the oxygenated composition (w/w%) in fresh CPOs. The tendency for classification agreed in the two analyses. Nootkatone was the only discriminating component of the pummelo species from others." \\
