China Daily reported about a man named Wang Dawei, a youtiao street food vendor from Weifang in East China‘s Shandong province, who offered a 100,000RMB reward to any individual who could disprove his claim that his youtiao was not aluminum-free. Many people know that the secret ingredient local street food vendors use to make their youtiao extra-puffy and crispy is aluminum sulfate crystals, a highly toxic ingredient if consumed too often or at large amounts.

“Using a unique technique, Wang’s youtiao onlycontain 0.7 milligram of aluminum per kilogram. This not only reaches the international standard of 100 milligram per kilogram, but isalso lower than the ceiling of 10 milligram per kilogram for fried food issued by the European Union.”
