General description

2-Methyl-3-furanthiol, a sulfur-containing compound, is the key odorant in cooked ham, wine and canned tuna fish.

Application


  • Elucidating salt-reduction mechanisms of aroma-active compounds from yeast extracts through sensomics approaches and electroencephalography.: This innovative study leverages both sensory science and neurotechnology to uncover how 2-methyl-3-furanthiol and other key compounds in yeast extracts can enhance flavor profiles while reducing sodium content in foods, aligning with health trends and consumer demands for lower-sodium options (Shan et al., 2024).

  • Widely Targeted Metabolomics and Network Pharmacology Reveal the Nutritional Potential of Yellowhorn (Xanthoceras sorbifolium Bunge) Leaves and Flowers.: This study demonstrates the use of targeted metabolomics to profile bioactive compounds, including 2-methyl-3-furanthiol, in Yellowhorn plant parts, which are emerging as a nutritional powerhouse with potential health benefits (Sha et al., 2024).

  • Metabolomics reveals factors affecting the radical reaction of sulfides during thermal processing for meaty aroma.: This research identifies how 2-methyl-3-furanthiol and other sulfides interact during cooking to create rich, meaty flavors, providing valuable insights for the culinary industry on optimizing flavor profiles in cooked meats (Zhang et al., 2024).
