Niacin in Enrichment Concentrates

Objective
Niacin is determined in vitamin and mineral concentrates (used to enrich cereals) by means of a colorimetric chemical reaction. Diluted sample solutions react with buffered ammonia solution and cyanogen bromide. The intensity of the resulting yellow color is proportional to niacin content.
