Some bioactive compounds found in pulses (phytates, saponins, tannins) display antinutritional properties and interfere with fat-soluble vitamin bioavailability (i.e., bioaccessibility and intestinal uptake). As canned chickpeas are consumed widely, our aim was to optimize the chickpea canning process and assess whether this optimization influences fat-soluble vitamin bioavailability. Different conditions during soaking and blanching were studied, as was a step involving prior germination. Proteins, lipids, fibers, vitamin E, lutein, 5-methyl-tetrahydro-folate, magnesium, iron, phytates, saponins and tannins were quantified. Bioaccessibility and intestinal uptake of vitamin D and K were assessed using in vitro digestion and Caco-2 cells, respectively. Significant reductions of phytate, saponin and tannin contents (-16 to -44%), but also of folate content (up to -97%) were observed under optimized canning conditions compared with the control. However, bioaccessibility and cellular uptake of vitamin D and K remained unaffected after in vitro digestion of test meals containing control or optimized canned chickpeas.
一些豆类中存在的生物活性化合物（植酸、皂素、单宁）具有抗营养特性，并会干扰脂溶性维生素的生物利用度（即生物可及性和肠道吸收）。由于罐装鹰嘴豆的广泛消费，我们的目的是优化鹰嘴豆的罐装过程，并评估这种优化是否会影响脂溶性维生素的生物利用度。研究了浸泡和烫漂过程中的不同条件，以及预先发芽的步骤。定量分析了蛋白质、脂肪、纤维、维生素 E、叶黄素、5-甲基四氢叶酸、镁、铁、植酸盐、皂素和单宁。使用体外消化和 Caco-2 细胞分别评估了维生素 D 和 K 的生物利用度和肠道摄取。与对照相比，在优化的罐装条件下，植酸、皂素和单宁的含量分别降低了 16%至 44%，叶酸含量也降低了 97%。然而，在体外消化含有对照或优化的罐装鹰嘴豆的试验餐时，维生素 D 和 K 的生物利用度和细胞摄取不受影响。
