SY4008 · PRIMARY AMINO NITROGEN (PAN)

Colorimetric method for primary amino anitrogen measurement

Yeasts need nitrogen to grow. One of the main sources of nitrogen are the proteins, peptides and amino acids present in the medium (primary amines, PAN); the other main source is the ammonium ion itself. The determination prior to the fermentation of the amount of assimilable nitrogen makes it possible to adjust it adequately to avoid unexpected stops of the fermentation process due to nitrogen deficit.
