PCR was applied due to stability of deoxyribonucleic acid [DNA] at high temprature and high conserved structure of DNA within all tissues of an individual. soybean was detected with AGID at 12%. 30% and 20% in raw kofta, sausage and beef burger, respectively, but not detected in minced meat.By using PCR native and modified soybeans were detcted in 100% and 69%, respectively in beed burger and at lower rates in other products
