Analysis of the present situation and countermeasures of the genetically modified ingredients in prepackaged food

ObjectiveThe 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.MethodsGB/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.ResultsAmong 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.ConclusionA 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.
