We tested eleven representative highly processed products samples (soya lecithin, soya protein powder,
chocolate beverage, infant rice cereal, soybean refine oil, soybean salad oil, maize oil, maize protein
powder, maize starch, maize jam) using the developed method, and amplicons of endogenous gene and
transgenic fragments were obtained from all the processed products except for soybean refined oil,
soybean salad oil and maize oil, and the sensitivity was 0.005%.
