Determination of the Total Volatile Basic Nitrogen (TVBN) in Fish
WebIf the TVB reaches 30 mg N/100 g most authorities consider the fish to be stale, whilst at level of 40 mg N/100 g the fish is regarded as unfit for consumption. Erkan, (2005) determined the total volatile basic nitrogen (TVB-N) using6%perchloric acid and the results were expressed as mg TVB-N per 100 g of wet sample. Nitrogen Recovery Verification: WebJan 17, 2012 · Total volatile base nitrogen (TVBN) is a widely used fish spoilage indicator.
