摘要
[目的]对云南墨江主产紫米各项指标及安全指标进行测定。[方法]以云南墨江紫米为研究对象，采用原子吸收分光光度计、气相色谱串联质谱仪、等离子体质谱仪、氨基酸自动分析仪等检测紫米成分、重金属含量和农药残留等，并评估其安全指标。[结果]在检测的紫米样品中，仅有2号样品检出毒死蜱含量超标，其他重金属及农药共22项指标均低于《绿色食品稻米》（ NY／T 419—2014）标准。[结论]该研究为制订云南墨江紫米地方标准奠定基础。
Abstract
Objective] To detect the index of purple rice in Mojiang County and its security index .[Method]With purple rice in Mojiang Coun-ty of Yunnan Province as the research object , we use atomic absorption spectrophotometer, gas chromatography tandem mass spectrometry, in-ductively coupled plasma mass spectrometry and automatic amino -acid analyzer to detect the components of purple rice, heavy metal content and pesticide residue.The security index was evaluated.[Result] Among the detected purple rice, chlorpyrifos content only exceeded in sample 2. As for other heavy metals and pesticide, a total of 22 indexes were lower than the standard in Green Rice Food (NY/T 419-2014).[Conclu-sion] This research provides basis for the establishment of local standard for purple rice in Mojiang County.
