中文摘要：本研究旨在研究消耗量很大的家用香料中黄曲霉毒素B1、B2、G1和G2的污染程度。作者利用HPLC方法分析了200个香料样品（100个有包装、100个无包装）的黄曲霉毒素图谱，发现污染发生率为61.5%，其中53.66%的样品超过了欧盟的限制标准。本研究是研究巴基斯坦包装和未包装香料中黄曲霉毒素发生率的第一份报告。结果表明，为了确保香料的安全消费，应该持续进行黄曲霉毒素监测，并应开展更多的研究来防止香料中黄曲霉毒素的增加。
外文摘要：The current research work aimed to access the contamination level of aflatoxins B1, B2, G1, and G2 in the household spices that are widely consumed in huge amounts. 200 different spice samples, 100 packed and 100 unpacked, were analyzed for the aflatoxins profile by HPLC with an incidence of 61.5% contamination out of which 53.66% samples exceed the EU limit. The results disclosed that the unpacked samples are more contaminated as compared to the packed samples except for white cumin seeds. Among packed and unpacked samples of spices, the maximum value of aflatoxins was detected in fennel, that is, 27.93 μg/kg and 67.04 μg/kg, respectively. The lowest concentration of aflatoxin was detected in cinnamon in packed form (0.79 μg/kg) and in the unpacked samples of white cumin seeds which is 1.75 μg/kg. Caraway seeds and coriander in its unpacked form showed positive results whereas black pepper (packed and unpacked) was found free from aflatoxins. This is the first report on the occurrence of aflatoxins in packed and unpacked samples of spices from Pakistan. To ensure safe consumption of spices, there should be constant monitoring of aflatoxin and more studies need to be executed with the intention of preventing mycotoxin accretion in this commodity.
