Abstract
To discriminate between the genetically modified soybean processed foods which were Korean traditional foods as Beansprout, doenjang, Beancurd (Tofu) and the unmodified one. we had analyzed comparatively that the loss degree of inner DNA about denaturalization factors in process step as heat or pressure and decision of suitable PCR primer by size. As a result of having compared about ${\beta}$-actin was 160bp, 335 promotor was 130 bp and NOS terminator was 132 bp effective. As a result of having checked a loss degree of a gene, as for the bean curd, DNA was mostly preserved well, and the loss of DNA along the processing process was hardly observed by a processing process. Most DNA of beansprout have moved to trunk after germination stage, and the appropriate analysis part was judged as the trunk. And the doenjang showed a detection difference of DNA by an operation of an enzye among self-life periods. Besides, after 50days, insertion gene was destoryed entrely so that detection was not possible.
