| Abstract: | Objective] To determine the content of 26 inorganic elements, which were K, Na, Ca, Mg, Fe, Mn, Zn, P, A1, Ti, Sr, Pb, Cd, Cu, Cr, Hg, As, Ni, Sn, Sb, Ba, B, V, Co, Ga, Se, in residue, flesh and terminal bud of pineapple. Method] Samples were diges- ted in a mixture of nitric and hydrogen peroxide. Microwave digestion-Inductively coupled plasma mass spectrometry （ICP-MS） was used to determinate sample. Result] The results showed that essential elements such as Ca, P, K, Na, Mg, microelements like Fe, Cu, Zn, Co, Mn, Ni, V, Sn, St, B, Se, were rich in pineapple. While other elements, which were commonly monitored in food like Pb, Cd, Cr, As, Hg, were found to be minimal in pineapple and its byproducts. Conclusion] Pineapple as well as its byproducts can be processed into various food products and medicine, therefore, monitoring inorganic elements in pineapple will improve products＇ safety and contribute to product pro- cessing technics optimization. |
