Abstract Cassava is the staple food of one billion people worldwide.Today,cases of cassava poisoning still occur frequently.In this paper,the toxicity of cassava was verified by culture of Escherichia coli.Moreover,the hydrocyanic acid responsible for its toxicity from the hydrolysis of cyanogenic glycosides was demonstrated by picric acid detection method.The removal effects of hydrogen peroxide oxidation and baker’s yeast fermentation on the toxicity of cassava were explored.Through this vivid analogy,readers can deeply understand the toxicity principle of cassava.We have also designed an interesting interactive program that allows readers to explore the methods and principles of detoxification of cassava through commonly used kitchen materials,which aims to stimulate readers’ interest in exploring chemistry and enhance teenagers’ passion in learning chemistry.
