摘　　要：目的对市售预包装食品中转基因成分状况进行抽样分析,并对转基因食品标识制度进行探讨。方法采用GB/T 38505—2020《转基因产品通用检测方法》,以大豆加工产品、玉米加工产品、油菜加工产品、水稻加工产品、马铃薯加工产品5个转基因作物加工产品为研究对象,通过检测10个能覆盖所有商业化转基因品系的片段,同时对玉米、大豆、油菜、水稻和马铃薯5大作物的内源基因进行检测。根据扩增结果可判断样品是否含有转基因成分。结果抽检的42种产品中,共检出6批次大豆类制品、1批次马铃薯类制品、3批次玉米类制品含有转基因成分。结论现有的预包装食品中有一定比例产品可检出转基因成分,需要进一步严格规范食品标识制度。Objective The status of genetically modified ingredients in prepackaged food was investigated and analyzed,and the labeling system and practical use of genetically modified food in China was discussed.Methods GB/T 38505—2020 General detection methods for genetically modified products were used to detect 5 genetically modified crops(soybean,maize,rape,rice,and potato)in processed products.Ten exogenous gene fragments of five crops that could cover all commercial genetically modified events were tested at one time.Results Among the 42 products sampled,6 batches of soybean products,1 batch of potato products,and 3 batches of corn products containing genetically modified components were detected.Conclusion A certain proportion of genetically modified ingredients in the existing prepackaged food products can be detected,and this needs to be further regulated by a strict food labeling system.
