Mineral contents of edible tissues and peels of some fruits consumed as traditional provided from three different countries

Mineral contents of some tropical fruits were determined by Inductively Coupled Plasma Atomic Emission Spectrometry. Phosphorus contents of Portuguese samples ranged from 884.63 mg/kg (Laranga Nacional orange) to 1605.57 mg/kg (lemon). In addition, P contents of Spainish citrus fruits ranged from 865.24mg/kg (Lemon) to 1227.39 mg/kg (orange). While potassium contents of Portuguese fruits ranged from 9618.96 mg/kg (Laranja Nacional orange) to 15704.95 mg/kg (lemon), K contents of Spain samples were found between 10946.18 mg/kg (Mandarin) and 16312 mg/kg (orange). As a micro element, Fe contents of Portugal samples ranged from 9.47 mg/kg (Grape fruit Turanja vermelha) to 15.69 mg/kg (lima). Zinc contents of Portuguese fruit samples changed between 2.32 mg/kg (mandarin) and 7.75 mg/kg (lemon). The highest and the lowest K contents were found in Turkey orange (16459.66 mg/kg) and lemon peels (5534.64 mg/kg). Phosphorus contents of Portuguese Citrus fruit peels ranged from 418.99 mg/kg (Laranja National orange) to 1086.55 mg/kg (Ortanique orange). Generally, P and K contents of edible tissue of Citrus fruits were found higher compared with results of citrus fruit peels.
