    Fake stinky tofu is poisonous tofu made with odorous essence lightly for five minutes. Smelly essence is ferrous sulfate (colored) with sodium sulfide (flavored). Ferrous sulfate is mainly used in the manufacture of pigments, preservatives and feed additives. Sodium sulfide is also called alkali sulfide, and the aqueous solution is strongly alkaline. Sodium sulfide deliquesces in the air and continuously releases hydrogen sulfide gas. Needless to say, these two kinds of chemical raw materials have certain toxicity, and their harm is more than that of healthy human stool.
