Recently, the importance of food safety is increasing due to numerous junk food. Junk food means to violate the law in stage such as production, manufacture, distribution, and sale of food. Many crop plants are processing as foods including bread, noodle, and other foods for supporting nutrition to human. For example, rice is one of the most well-known food crops in the world, and processed rice is being mixed with other processed crops to health food. The object of this study is to detect amount of specific grains, i.e. rice from processed foods mixed with other cereals. This experiment was performed to the following two steps: 1) designed the specific primer sets based on chloroplast DNAs, 2) amplified products using real-time PCR. We designed eleven primer sets within chloroplast DNA of rice, and then the confirmation of primer efficiency was to amplified with rice genomic DNA using real-time PCR. In addition, these primer sets were applied in other crops such as wheat, maize, and adlay to confirm specificity to rice. The rice specific primer sets were determined by the number of amplification and the melting peak through real-time PCR. As a result, five primer sets were confirmed to uniqueness in the rice genome. In conclusion, the specific primer sets would be useful for identifying rice grain from the processed foods to eliminate junk foods and for contribution of food safety.
