Problems solved by technology

[0004] At present, there are many methods for determining the content of hydrogen peroxide, mainly chemical titration, titanium salt colorimetry, high performance liquid chromatography, chemiluminescence, fluorescence photometry, electrochemical analysis, etc., the first two methods Although they are all chemical methods, they have large errors, low accuracy, and long detection time; although high-performance liquid chromatography has high sensitivity and good selectivity, it is not suitable for the rapid detection industry, and the cost of large instruments is high and time-consuming; Chemiluminescence, fluorescence photometry, and electrochemical analysis methods are relatively complicated and inconvenient to operate, which is not conducive to the on-site rapid detection of residual hydrogen peroxide in food by non-professionals such as food processing enterprises, food supervision departments, and even consumers.

Description

technical field [0001] The invention relates to the technical field of food safety monitoring, in particular to an integrated rapid detection tube for hydrogen peroxide and a method for rapid detection of hydrogen peroxide. Background technique [0002] Hydrogen peroxide is also called hydrogen peroxide, a colorless liquid, and has oxidation-reduction properties. It is a strong oxidizing agent. In daily life, it is often used as an oxidizing agent, bleaching agent, disinfectant, and cross-linking agent. It is widely used in industrial and medical fields. . Hydrogen peroxide is used by many food manufacturers in food production, processing, and packaging materials due to its high-efficiency sterilization, low residue, easy decomposition, and good bleaching effect to improve product shelf life, bleach food, and increase food aesthetics. [0003] However, in the process of using hydrogen peroxide, it is often accompanied by the decomposition and residue of the oxidizing agent....
