Determination of Ammonia in Plant-based Beverages
In plant-based beverages, ammonia can derive from amino acid deamination processes, linked to protein degradation by endogenous enzymes or contaminating microorganisms. This can occur during extraction, enzymatic hydrolysis or during non-optimal storage. CDR DrinkLab allows the determination of ammonia content in a simple and fast way to monitor protein alterations, evaluate the hygienic-sanitary quality of the product and control microbiological stability along the entire production chain.
Method
Sample treatment
The sample must be centrifuged (code 222061) before the analysis.
Principle of the test
The ammonium ions react with a phenolic derivative and form a blue-green colored complex whose intensity, measured at 700 nm, is directly proportional to the concentration of ammonia in the sample.

Calibration curve
The calibration curve was made using samples with known ammonia value. The curve trend confirms the excellent linearity of the system over the entire measurement range.
