Beschreibung

Allgemeine Beschreibung

3-Methylindole (3-MI), commonly found in wine, dairy products, and other foodstuffs, leads to an unpleasant fecal like odor in pig meat products. It is reported to be produced in the intestines of several species by the microbial degradation of tryptophan.

Anwendung

3-Methylindole may be used as an analytical reference standard
for the quantification of the analyte in the following:

• Faeces intestinal contents, and bacterial cultures using gas chromatography with nitrogen-phosphorus detector (GC-NPD).
• Adipose tissue of pigs using reversed-phase high-performance liquid chromatography with UV detection (RP-HPLC-UV).
• Pit mud and baijiu (SAB) samples using gas chromatography-olfactometry (GC–MS/O) and gas chromatography coupled to mass spectrometry (GC–MS).

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
