Abstract
Genetically modified (GM) ingredients found in imported raw materials and processed foods were monitored in the province Gyeongin in Korea. The analysis was performed according to "Testing methods for genetically modified foods of food standards and specifications" established in Korea. We received 120 items from the Gyeongin Regional KFDA. Only two of the 120 items analyzed in the samples, were contaminated with GM ingredients. However, we could not analyze the internal standard gene from 12 processed foods. We found that the extracted total DNA of the above 12 samples were extracted and found to be degraded. The total DNA contained a very small fragment of less than 300 base pair. Therefore, it seems that the total DNA is not large enough to serve as the template DNA for PCR analysis.
