9.10.1 - Free Amino Nitrogen in Beer by Spectrophotometry (IM)

The international method for the determination of free amino nitrogen in pale or dark beers. The method gives an estimate of amino acids, ammonia and, in addition, the terminal α-amino nitrogen groups of peptides and proteins. Proline is partially estimated at the wavelength used.

It is necessary to use EBC Method 8.10

9.10.2 - Free amino niytrogen in Beer by discrete analyser (NOPA Method)

The determination of the free amino nitrogen content in beer using photometric measurement of OPA (o-Phthaldialdehyde) and NAC (N-acetyl cysteine). The method is performed manually or automatically at a 340 nm wavelength at 37 °C temperature. In the automated method, the side wavelength of 700 or 750 nm is also measured. The method estimates amino acids by measuring the terminal α-amino nitrogen groups of peptides and proteins. The method is specific for α-amino nitrogen. Proline, ammonia or ammonium are not included.
