Mineral content, total phenolic compounds (TPC), and antioxidant capacity were determined in three samples of purple-açaí (coarse-PAC, medium-PAM, and fine-PAF), and one of white-açaí (coarse-WAC) and their respective bioaccessible fractions. TPC content differed in all samples, with PAC (583.79 mgAGE/100 g) having the highest content; however, PAM showed higher bioaccessibility (32.27%). PAC presented higher antioxidant capacity in the FRAP tests (74.34 μM FeSO₄/g) and ABTS (55.05 μM Trolox/g). However, no differences were found in DPPH between PAC (1986.66 EC50) and PAM (2408.88 EC50) samples. Antioxidant capacity was decreased in all samples after digestion. Potassium was in the highest proportion (7121.90 mg/100 g-PAC), followed by Ca (349.92 mg/100 g-PAM), and Mg (169.41 mg/100 g-PAM), in all the samples. However, Ca presented the highest bioaccessible fraction, followed by Mg and Mn, with the highest percentages observed in WAC samples (90.30, 74.30, and 64.52%, respectively).

体外胃肠消化对紫色和白色巴西莓商业果肉（Euterpe oleracea Mart.）的矿物质含量、酚类化合物和抗氧化能力的影响。


测定了三种紫色巴西莓样品（粗粒-PAC、中质-PAM 和细粒-PAF）和一种白色巴西莓样品（粗粒-WAC）及其各自的生物可利用级分。所有样品中TPC含量不同，其中PAC含量最高（583.79 mgAGE/100 g）；然而，PAM 显示出更高的生物可及性（32.27%）。 PAC 在 FRAP 测试 (74.34 μM FeSO ₄ /g) 和 ABTS (55.05 μM Trolox/g) 中表现出更高的抗氧化能力。然而，PAC (1986.66 EC50) 和 PAM (2408.88 EC50) 样品之间的 DPPH 没有发现差异。消化后所有样品的抗氧化能力均下降。在所有样品中，钾的比例最高（7121.90 mg/100 g-PAC），其次是钙（349.92 mg/100 g-PAM）和镁（169.41 mg/100 g-PAM）。然而，Ca 的生物可访问分数最高，其次是 Mg 和 Mn，在 WAC 样品中观察到的百分比最高（分别为 90.30、74.30 和 64.52%）。
