摘要
Total concentrations of Ca, Cu, Fe, Mg, Mn and Zn were determined by flame atomic absorption spectrometry (FAAS) in commercial honeys of a stated origin using the direct analysis of their 5.0 (m/v) sample solutions. In addition, in vitro bioaccessibility assay with a simulated gastrointestinal juice was used and demonstrated that very high fractions (80-100%out of total concentrations) of these elements are bioaccessible from analysed honeys. However, it seems that only for Mn a daily intake of 100 g of honey can supply a relatively high contribution (up to 65%out of 2-3 mg day鈭?) to the recommended daily allowance (RDA) of this element for adults. In case of other elements, the coverage of RDAs was much lower as compared to Mn, i.e., 0.2-1.2%(Ca), 2.2-8.5%(Cu), 0.5-19.2%(Fe), 0.1-4.4%(Mg) and 0.3-16.5%(Zn).
