The grapefruit is a subtropical citrus tree grown for its fruit which was originally named the "forbidden fruit" of Barbados.[5] The fruit was first documented in 1750 by Rev. Griffith Hughes when describing specimens from Barbados.[6] All parts of the fruit can be used. The fruit is mainly consumed for its tangy juice.[7] The peel can be processed into aromatherapy oils[8] and is also a source of dietary fiber.[9] The seed and pulp, as byproducts of the juice industry, are retrieved for GSE processing[6] or sold as cattle feed.[10]
