Abstract Nowadays hydrogen peroxide in food becomes more and more frequent. In order to establish a convenient, effective and rapid method to detect, a test paper for hydrogen peroxide semiquantitative detection tested by 25 different samples was prepared. The disadvantages of the existing methods are long response time, long production period and poor stability. The detection could be completed in 3 s with 3 mm chromatography filter paper. The craft of extraction could be optimized by orthogonal design, and the production period has been shorten. The protective enzyme was added in the color liquid, which gave the stability and shelf life of the test paper. The results showed that the test paper was consistent with iodometry tested by 25 different samples. The method of test paper was quick, easy, sensitive, and had good specificity. Consequently, this simple and inexpensive detection method can be widely applied in inspection of sanitation field, which is of great significance for rapid detection of hydrogen peroxide in food.
