摘要

本研究的目的是测定和评估蜜蜂和蜂胶样品中Ca、Fe、Mg和Mn的生物可及性。采用火焰原子吸收光谱法测定了蜂胶消化液中总钙、铁、镁、锰及生物可及组分的含量。消化后获得的Ca、Fe、Mg和Mn含量范围为423.43–4368.42、3.85–814.92、139.02–1170.68和14.28–67.29 Mg kg–1。模拟胃消化Ca、Fe、Mg和Mn后的生物可及含量分别为17.62–63.35、0.12–1.64、26.06–86.34和12.08–83.05%。在胃肠道模拟中，Ca的浓度在3.05–73.08%之间，Fe的浓度在0.63–2.45%之间，Mg的浓度在0.16–43.26%之间，Mn的浓度在1.47–8.45%之间。总的来说，与胃肠道消化相比，模拟显示胃后的生物可及含量更高。

Bioaccessibility of Ca, Fe, Mg, and Mn in Brazilian Propolis

The objective of this study was to determine and evaluate the bioaccessibility of Ca, Fe, Mg, and Mn in Apis mellifera and Melipona propolis samples. Flame atomic absorption spectrometry was used for the determination of total Ca, Fe, Mg, and Mn in digested propolis, and of the bioaccessible fractions. The levels of Ca, Fe, Mg, and Mn obtained after digestion ranged from 423.43 – 4368.42, 3.85 – 814.92, 139.02 – 1170.68, and 14.28 – 67.29 mg kg–1, respectively. The bioaccessible contents after simulated gastric digestion of Ca, Fe, Mg, and Mn ranged from 17.62 – 63.35, 0.12 – 1.64, 26.06 – 86.34, and 12.08 – 83.05%, respectively. In the simulation of the gastrointestinal tract, the concentrations ranged from 3.05 – 73.08% for Ca, 0.63 – 2.45% for Fe, 0.16 – 43.26% for Mg, and 1.47 – 8.45% for Mn. In general, the simulation showed higher bioaccessible contents after gastric, compared to gastrointestinal digestion.
