General description

Skatole is an indole derivative with a strong fecal odor that occurs naturally in feces formed due to the degradation of tryptophan. It is found in several flowers such as jasmine owing to its flowery smell when present in low concentration. Skatole is also one of the key contributors to the development of boar taint in fat samples.

Expression of water soluble proteins of fresh pork Longissimus thoracis from 4 pure breed pigs (Duroc, Large White, Landrace, and Piétrain) was studied to identify candidate protein markers for meat quality. Surface-enhanced laser desorption/ionisation time-of-flight mass spectrometry (SELDI-TOF-MS) was used...
