Determination of metal non metal and heavy metal contents of some tropical fruits growing in Indonesia

English (OpenAlex)

The importance of the current study was to determine the mineral and heavy metal contents of several tropical fruits provided from Indonesia. Mineral contents of some tropical fruits were determined by inductively coupled plasma-atomic emission spectrometry. As macro element, Ca contents of fruits were found between 167 mg/kg (Pir) and 1,051 mg/kg (Jambu). In addition, K contents of fruits ranged from 5,803 mg/kg (Manggis) to 17,659 mg/kg (Dragori). P contents ranged from 491 mg/kg (Sukun) to 3158 mg/kg (Dragori) (P<0.05). As micro element, Fe content varied between 24.7 mg/kg (Pir) and 54.1 mg/kg (Dragori). In addition, while Mn contents of fruits change between 2.3 mg/kg (Sukun) and 33.2 mg/kg (Starfruit), Zn content varied from 2.9 mg/kg (Sukun) to 37.5 mg/kg (Dragori) (P<0.05). As heavy metal, Cd, Cr, Mo and Ni contents of fruits were found at low levels.
