چکیده انگلیسی
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 24 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 gâ 1, were observed for K (4526-9768), P (3418-7014) and Mg (2527-4633), whereas Mo (< 0.11-2.6), Cu (12 â 32) and Mn (12-61) presented the lowest concentrations. The highest bioaccessible fractions in gastric phase were observed for K (16-26%), Mg (22-28%), Mn (19-27%), P (25-36%) and Zn (16-25%). In addition, it was found through the application of in vitro simulated gastrointestinal digestion that only a minor fraction of total Fe and Cu was potentially bioaccessible in this samples.
