Grapefruit juice concentrate, unsweetened, is grapefruit juice with some of its water removed. The figures describe the concentrate rather than juice diluted for drinking. It provides mainly carbohydrate in the form of sugars. Per 100g, it contains 709 kJ of energy, 41g of sugars, 190mg of vitamin C and 560mg of potassium.
Vitamin C supports normal immune function and helps the body absorb iron from plant foods. Unsweetened does not mean sugar-free, and the concentrated sugars and energy are relevant when monitoring intake. Dilution changes the amount of nutrients in a given weight of prepared juice. Grapefruit can also interact with certain medicines, altering their levels in the body. Full nutritional figures are in the tables below.

About these figures
Values are per 100g of the food as described (8 samples, 50.4 Brix; imported commercial concentrate). "Trace" means only a very small amount was found. Nutrients that were not measured are not shown. Salt is calculated from sodium.
These figures come from an older part of the dataset that is no longer updated. Original source: LGC, The nutritional composition of fruit juice, 1984.
