Abstract

The invention provides benzoyl peroxide test paper. The benzoyl peroxide test paper comprises a test paper substrate and a detection layer arranged on the test paper substrate, wherein the detection layer comprises a detection base layer and a color development layer, and the color developing layer is formed by drying the detection base layer after infiltrated in a color developing solution; the color developing solution comprises the following components calculated by mass concentration: 0.3 to 2g/L of thiomidone, 0.05 to 0.5g/L of Tween-80, 0.1 to 1.5g/L of 3,3,5,5-tetramethylbenzidine, 3 to15g/L of a methyl vinyl ether-maleic anhydride copolymer, 500 to 800g/L of absolute ethanol, and the balance of pure water. The benzoyl peroxide test paper disclosed by the invention has simple and convenient operation, short reaction time, low detection limit, high sensitivity, high accuracy, low single detection cost and long shelf life.

Description

technical field [0001] The invention belongs to the field of food detection, and in particular relates to a benzoyl peroxide detection test paper, a preparation method and a detection method thereof. Background technique [0002] In the field of food safety testing, analytical methods for benzoyl peroxide include gas chromatography, liquid chromatography, spectrophotometry, chemiluminescence, ion chromatography, and the like. Although these methods have the advantages of high detection accuracy, low detection limit, and good repeatability, there are also problems such as cumbersome and time-consuming sample pretreatment steps, expensive detection instruments, long detection cycle, high cost, and excessive reliance on professional and technical personnel. It is conducive to the large-scale preliminary screening of the grass-roots quality inspection department, which is not conducive to the rapid detection on the spot. [0003] And though the kit colorimetric method and test ...
