  • Applications

    cis-1-Propenyl propyl trisulfide (CAS 23838-26-8) is a characteristic Allium organosulfide used primarily as a flavor ingredient to recreate fresh/cooked onion–garlic notes in savory seasonings, sauces, soups, snacks, canned foods, and plant-based formulations at trace levels to boost authenticity and roasted-onion nuances; it is also employed as an analytical reference in GC-MS/GC-O for quality control of onion/garlic oils, raw-material authentication, aroma profiling, and odor-release studies, as well as in research on encapsulation, flavor stability, matrix interactions, and controlled delivery during processing; additionally it can help mask off-notes and enhance meaty–umami perception when combined with pyrazines, mercaptans, or disulfides, with recommendations for inert, light-protected storage to minimize oxidation and odor degradation in line with applicable flavor-safety regulations.
