　　The bright white yuba may be poisonous food that has been added with white yuba. It is inedible and has nothing to do with high quality. In fact, white yuba is an industrial whitening agent. In order to make the yuba whiter, smoother and tougher, criminals illegally mix the toxic substance white yuba into it. Although cornstarch can improve the appearance and taste of food, it will decompose into highly toxic carcinogens when heated.
