对含污染物镉的大米主食样品米饭和米线进行体外模拟消化,采用石墨炉原子吸收分光光度法(GF-AAS)对样品中镉进行定量检测。口腔阶段镉释放率:生大米原料粉(34.85%) >米线(5.69%) >米饭(0%);胃阶段释放率:米饭(74.51%) >米线(71.62%) >生大米原料粉(0%);小肠阶段中的最大释放率为:4 h时生大米原料粉(60.19%) >7 h时米线(45.35%) >5 h时米饭(37.06%)。结果表明:不同大米主食样品在不同消化阶段中污染物镉的消化释放有显著差异,已消化释放出的镉在不同时间和消化部位还会被重新吸附结合,使镉释放率增加又降低;在小肠1~3 h消化时间下,米饭中镉消化释放率显著大于米线样品,而小肠消化>3h后,则相反。该...

In vitro digestion models were widely used to study digestibility and release of food components under simulated conditions. It was investigated that the effect of rice staple products on cadmium release in contaminated rice. The rice stable products including cooked rice and rice noodles were used to research via a three-step procedure simulating digestive processes of mouth, stomach, and small intestine, and graphite furnace atomic absorption spectrometry (GF-AAS) was used to measure the cadmium content. The results showed that processing met...
