Descrizione

Descrizione generale

3-Methylindole (3-MI), commonly found in wine, dairy products, and other foodstuffs,[1] 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.[2][3]

Applicazioni

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).[2]
• Adipose tissue of pigs using reversed-phase high-performance liquid chromatography with UV detection (RP-HPLC-UV).[3]
• Pit mud and baijiu (SAB) samples using gas chromatography-olfactometry (GC–MS/O) and gas chromatography coupled to mass spectrometry (GC–MS).[1]
