Abstract: Several incidents on food adulteration were reported in recent times. Currently,China has not established appropriate standards to identify various food ingredients. However,in order to control food adulteration,various technologies such as spectrophotometer,gas chromatography-mass spectrometry(GC-MS),high performance liquid chromatography(HPLC),and DNA barcoding have been developed. Among these techniques,DNA barcoding is a fast,accurate,efficient and non-targeted biotechnology advantage with the principle of using 400-800 bp long standardized unique DNA sequences to analyze and classify the food commodities. This article reviews the common plant DNA barcoding and their applications in identifying legumes,oils,medicinal and edible homologous,spices,berry beverages,health foods,etc.,laying the foundation for the wider application of this technology in setting standards for quality assurance,quality control and food safety for different food products.
