One of China’s and other Asian countries food staples are sweet potato noodles. However, almost 60% of investigated samples tested positive for cassava, a common adulterant in sweet potato noodles (and also the basis for tapioca). The DNA of 52 samples was extracted and analyzed by the real-time loop-mediated isothermal amplification (Real-time LAMP) method, which showed accurate detection down to a 1% limit.
