| Considered to be an important flavour chemical for meat flavours; also used in nut flavors. van den Ouweland, Demole & Enggist (1989) have noted that a 5- or 6- membered planar ring substituted with an "ene-thiol" and a methyl group adjacent to the thiol is important for the generation of meaty flavour/aroma. Normal use levels in finished consumer product: 0.005-0.25ppm. | Roasted meat; sweet beef broth, HVP notes |
