Enzyme test peper for detecting hydrogen peroxide concentration

Abstract

This invention relates to a kind of enzyme test paper capable of testing hydrogen peroxides in a sample quickly prepared by an enzymatic chromogenic reaction, which utilizes the adsorption action with anion carriers to fix the horseradish peroxide enzymes with positive charges and a developer on a carrier at the same time, which can test the existence of hydrogen peroxides with the concentration to 0.5mumol / L in the sample and the response time of the test paper is 1 minute.

Description

technical field

[0001] The invention relates to an enzyme test paper for rapidly detecting the content of hydrogen peroxide in a sample by using an enzymatic color reaction, and belongs to the field of enzymatic analysis in the field of biotechnology. Background technique

[0002] Hydrogen peroxide, commonly known as hydrogen peroxide, can be decomposed into water and oxygen under conditions such as stirring and light, and is extremely oxidizing and corrosive, so it is widely used as a disinfectant and bleaching agent for food. According to my country's "Hygienic Standards for the Use of Food Additives", food-grade hydrogen peroxide is allowed to be used as a processing aid in food production, but it should be removed before it is made into a finished product, and the residue should be strictly controlled. Excessive hydrogen peroxide residues in food will cause serious harm to the human body, such as: damage the digestive tract, cause cancer, accelerate human aging, induce c...
