采用全仿生消化（体外）方法对晋江牡蛎（Crassostrea rivularis）和花蛤（Paphia undulata）的可食用组织进行动态提取。分析了不同烹饪方法对食用贝组织中 Zn 和 Cd 生物利用度的影响，并评估了 Zn 和 Cd 对人类健康的风险。结果表明，未加热的 C. rivularis 和 P. undulata 样品中 Zn 和 Cd 的胃仿生提取高于肠道仿生提取。熟样品的提取模式与原始样品的提取模式一致。C. rivularis 熟样品中 Zn 和 Cd 的生物利用度分别为 94.9% 和 82.5%，表明与原始样品相比，Zn 生物利用度增加，但 Cd 生物利用度降低。P. undulata 熟样品中 Zn 和 Cd 的生物利用度分别为 85.1% 和 83.0%，与原始样品相比均有所降低。食用 C. rivularis 可提供每日所需锌摄入量的 21.0% 至 34.2%，而食用 P. undulata 可提供 3.8% 至 6.4%。两种贝类的 Cd 摄入量均低于 FAO/WHO 建议的每月可耐受摄入量。食用煮熟的 C. rivularis 可以增加 Zn 的摄入量并减少 Cd 的摄入量。

Bioavailability and health risk assessment of Zn and Cd in edible tissues of two typical shellfish species using in vitro gastrointestinal digestion

Dynamic extraction of edible tissues of Jinjiang oyster (Crassostrea rivularis) and Flower clam (Paphia undulata) was conducted using a fully biomimetic digestion (in vitro) method. The impact of different cooking methods on the bioavailability of Zn and Cd in the edible shellfish tissues was analyzed, and the human health risk of Zn and Cd was evaluated. The results show that the gastric biomimetic extractions of Zn and Cd in unheated samples of C. rivularis and P. undulata were higher than those in the intestinal biomimetic extraction. The extraction patterns of cooked samples were consistent with those of raw samples. The bioavailability of Zn and Cd in cooked samples of C. rivularis was 94.9% and 82.5%, respectively, indicating increased Zn bioavailability but decreased Cd bioavailability compared to the raw samples. The bioavailability of Zn and Cd in cooked samples of P. undulata was 85.1% and 83.0%, respectively, both of which decreased compared to the raw samples. Consumption of C. rivularis can provide 21.0% to 34.2% of the daily required Zn intake, while consumption of P. undulata can provide 3.8% to 6.4%. The intake of Cd from both shellfish species is below the monthly tolerable intake recommended by FAO/WHO. Consuming cooked C. rivularis can increase the intake of Zn and decrease the intake of Cd.
