Analysis of hydrogen peroxide in aqueous solution
Hydrogen peroxide (H2O2) is a sanitizing agent widely used in beverage production plants to eliminate bacteria, yeasts and molds thanks to its oxidizing action. It is commonly applied in the cleaning of tanks, pipelines and bottling lines. However, it is essential to control its concentration, as residual hydrogen peroxide may contaminate the beverage during bottling or storage. Therefore, its analytical determination is crucial: maintaining its concentration below regulatory limits ensures food safety and product quality.
Method
Test type: End Point.
Time testing: 4 minutes.
Analysis sessions with multiple samples are possible up to a maximum of 16 tests for CDR DrinkLab®.
...
Sample treatment
Use aqueous solution as is.
Principle of the test
Hydrogen peroxide reacts with a phenolic derivate and peroxidase, and forms a pink colored complex whose intensity measured at 505 nm, is directly proportional to the concentration of hydrogen peroxide (H2O2) in the sample.
