Abstract Given the importance of knowing the real nutritional value of food, the main objective of this study was to evaluate the total elements concentrations and bioaccessibility of Ca, Cu, Fe, K, Mg, Mn, Mo, Na, P and Zn in linseed and sesame samples. A full 2 4 factorial design was applied to optimize the microwave assisted acid digestion of the samples. Total elements concentrations were obtained by inductively coupled plasma optical emission spectrometry (ICP OES). Extraction procedures were performed using the Unified Bioaccessibility Method (UBM) to evaluate the bioaccessibility. The highest total content, in μg g − 1 , were observed for K (4526–9768), P (3418–7014) and Mg (2527–4633), whereas Mo ( in vitro simulated gastrointestinal digestion that only a minor fraction of total Fe and Cu was potentially bioaccessible in this samples.

亚麻籽和芝麻中 Ca、Cu、Fe、K、Mg、Mn、Mo、Na、P 和 Zn 的测定和体外生物可及性评价

摘要 鉴于了解食物真正营养价值的重要性，本研究的主要目的是评估亚麻籽中 Ca、Cu、Fe、K、Mg、Mn、Mo、Na、P 和 Zn 的总元素浓度和生物可利用性。和芝麻样品。应用完整的 2 4 因子设计来优化样品的微波辅助酸消解。通过电感耦合等离子体发射光谱法 (ICP OES) 获得总元素浓度。使用统一生物可及性方法 (UBM) 执行提取程序以评估生物可及性。K (4526–9768)、P (3418–7014) 和 Mg (2527–4633) 的总含量最高，以 μg g − 1 为单位，而 Mo（体外模拟胃肠道消化，仅占总含量的一小部分） Fe 和 Cu 在该样品中具有潜在的生物可及性。
