Application

Isovaleric acid may be used as an analytical reference standard for the quantification of the analyte in the following:
  • Rose apple (Syzygium jambos Alston) fruit using gas chromatography with flame ionization detection (GC-FID), mass spectrometry (GC-MS) and olfactometry/aroma extract dilution analysis (GC-O/AEDA).
  • Sicilian goat cheese using gas chromatography with flame ionization detection (GC-FID) and mass spectrometry (GC-MS).
  • Food products using gas chromatography with flame ionization detection (GC-FID).
