Abstract:

Unintended effects from exogenous gene may form new metabolites or change metabolic patterns and nutrients
of genetically modified crops, and even generate some new toxic substances. The study on unintended effects is one of
the important contents of safety evaluation of genetically modified foods. This review focuses on the latest applications of
metabolomics in evaluation of unintended effects of genetically modified crops, and describes research expectations in this
field, so as to promote the development and improvement of safety evaluation system for genetically modified foods.

Key words: genetically modified crops, metabolomics/metabonomics, unintended effects, evaluation
