Haloanisoles – Halophenols

Haloanisoles

Haloanisoles are responsible for “mouldy”’ and cork defects. The compounds most often found in wines are the following: 2,4,6-trichloroanisole (TCA); 2,3,4,6-tetrachloroanisole (TeCA); 2,3,4,5,6-pentachloroanisole (PCA); and 2,4,6-tribromoanisole (TBA).

Their determination either confirms or denies their involvement in wine contamination. In addition, it can be used to detect potential sources of contamination.

It should be noted that these molecules are extremely fragrant and they alter the wines in an irreversible way.

Halophenols

Halophenols are the biochemical precursors of haloanisoles:

  • 2,4,6-trichlorophenol (TCP) → TCA
  • 2,3,4,6-tetrachlorophenol (TeCP) → TeCA
  • 2,3,4,5,6-pentachlorophenol (PCP) → PCA
  • 2,4,6-tribromophenol (TBP)→ TBA

Used to protect wood, TCP, TeCP and PCP are responsible for air contamination. TBP is a flame retardant recently identified in some contaminations.

Our laboratory has recently developed new methods to detect these contaminants on all matrices. Indeed SARCO proposes an extremely powerful method to simultaneously determine key molecules that can be found in wines with a detection limit below the allowable limits. With this very fast method we provide a result within 2 days.
