摘要

为了减少小麦中镉和铅对健康的危害,我们进行了一项田间试验,研究了 11 个小麦品种籽粒中镉和铅生物可及性的差异及其与籽粒营养成分的关系。11 个栽培品种谷粒中镉和铅的浓度(镉:0.14-0.56 毫克/千克-1,铅:0.08-0.39 毫克/千克-1)和生物可及性(肠道阶段镉和铅的生物可及性分别为 5.28-57.43%和 0.72-7.72%)差异显著。最终选择了健康风险相对较低、谷物中镉和铅浓度最低的安全小麦品种(Shannong16)。钙、镁、植酸和蛋氨酸在影响小麦中镉和铅的生物可利用性方面起着关键作用,其中钙和植酸与镉和铅的生物可利用性呈显著负相关。这些发现可用于优化安全小麦栽培品种的选育策略,促进镉污染农田的粮食健康生产。

Variations in Cadmium and Lead Bioaccessibility in Wheat Cultivars and Their Correlations with Nutrient Components

To reduce the health risks of exposure to Cd and Pb in wheat, a field experiment was conducted to investigate the differences in Cd and Pb bioaccessibility among the grains of 11 wheat cultivars and their relationships with the nutrient compositions of grains. The grain concentrations (Cd: 0.14–0.56 mg kg–1, Pb: 0.08–0.39 mg kg–1) and bioaccessibility (5.28–57.43% and 0.72–7.72% for Cd and Pb in the intestinal phase, respectively) of Cd and Pb differed significantly among the 11 cultivars. A safe wheat cultivar (Shannong16) with a relatively low health risk and the lowest grain Cd and Pb concentrations was selected. Ca, Mg, phytate, and methionine played key roles in affecting Cd and Pb bioaccessibility in wheat, with Ca and phytate significantly negatively correlated with Cd and Pb bioaccessibility. These findings can be used to optimize the selection strategy for safe wheat cultivars for healthy grain production in Cd-polluted farmland.
