摘　　要：目的分析2020年—2022年广州市售坚果与籽类食品中重金属、黄曲霉毒素和微生物等监测结果,为食品安全风险评估和政府监管提供依据。方法随机采集散装和定型包装坚果及籽类食品321份,按《国家食品污染和有害因素风险监测工作手册》检测铅、镉、铬、黄曲霉毒素、酸价、过氧化值、大肠菌群和霉菌。结果样品中监测项目均有检出,超标率为9.97%,超标项目是霉菌、大肠菌群、黄曲霉毒素B1、酸价。铅、铬、镉检出值在坚果食品中比籽类高;过氧化值在熟制坚果与籽类食品比生干制品高、籽类比坚果类高;酸价在熟制坚果与籽类食品比生干制品高,散装比预包装高;霉菌检出值在生干坚果与籽类食品比熟制制品高,籽类比坚果类高,散装比预包装高。结论广州市售坚果与籽类食品中重金属元素、黄曲霉毒素污染水平总体较低,其日暴露量远低于容许量,不会引起健康风险。但不能忽视个别样品中霉菌、黄曲霉毒素B1和酸价等超标的潜在危害性,特别是霉菌超标率相对较高,应引起高度重视。Objective This paper aims to investigate the contamination status of heavy metals,aflatoxin and microorganism in nut and seed foods in Guangzhou,so as to provide scientific evidence for the food safety risk assessment and intensified supervision of the government departments.Methods Pb,Cd,Cr,aflatoxins(B1,B2,G1,G2),acid value,peroxide value coliform group and mold were detected in 321 random samples of seeds and nuts in package and bulk according to National Food Contamination and Hazardous Factors Risk Monitoring Manual.Results The monitoring items in the samples were all detected.The total exceeding rate was 9.97%.The exceeding items were mold,coliform,aflatoxin B1,and acid value.The daily exposures of heavy metals and aflatoxin in seeds and nuts were much lower than the allowable daily intake.The detection value of mold in raw and dried seeds and nuts were higher than that in roasted seeds and nuts,but the detection value of peroxide and acid value in roasted seeds and nuts were higher than that in raw and dried seeds and nuts.The detected values of cadmium,lead and chromium in tree nuts were higher than those in seeds,but the values of mold and peroxide in seeds were higher than those in tree nuts.The detection value of mold and acid in prepackage is higher than that in bulk.Conclusion The contamination levels of heavy metals and aflatoxin in nut and seed foods which sold in Guangzhou are generally low,and their daily exposure is much lower than the allowable daily intake,which does not cause health risks.However,the potential harm of aflatoxin B1,acid value and mold in individual samples should not be ignored,especially the exceeding rate of mold is relatively high,which should be paid more attention to.
