Due to its lower cost, cassava starch is a common adulterant in higher priced starches, such as for potato and wheat. Tests with droplet digital polymerase chain reaction ddPCR in China uncovered that over 30% of sweet potato starch samples, 25% of cornstarch samples and 40% of potato starch samples were adulterated with cassava starch. Besides the economic impact, this kind of fraud also poses a risk to consumers allergic to cassava.
