A comparison was made of eight known and published PCR primer sets to detect zein, cryIA(b), bla and bar genes and the 35S cauliflower mosaic virus promoter of transgenic Bt "Maximizer" maize "event 176" (Novartis) in cooked food products. Transgenic pop corn, polenta and cookies were used as models. The polenta and cookies were made with different percentages (100, 1, 0.1% w/w) of transgenic maize flour. The DNA extracted from samples taken at different times of cooking revealed a progressive decrease in the average.
