Anwendung

• RIFM fragrance ingredient safety assessment, bis-(methylthio)methane, CAS Registry Number 1618-26-4.: This safety assessment explores the use of bis(methylthio)methane as a fragrance ingredient. The study evaluates its toxicological profile, confirming its safety for use in various cosmetic and personal care products (Api et al., 2021).


• Characterization of the Key Aroma Compounds in Three Truffle Varieties from China by Flavoromics Approach.: Bis(methylthio)methane is identified as a significant aroma compound in Chinese truffle varieties. The research uses a flavoromics approach to map out the aroma profiles, supporting the enhancement of truffle-based products (Feng et al., 2019).


• Multidimensional Gas Chromatography Coupled to Combustion-Isotope Ratio Mass Spectrometry/Quadrupole MS with a Low-Bleed Ionic Liquid Secondary Column for the Authentication of Truffles and Products Containing Truffle.: This analytical method leverages bis(methylthio)methane as a marker for authenticating truffle products. The study improves the reliability of truffle product verification, ensuring quality control in the food industry (Sciarrone et al., 2018).


• Olfactometry Profiles and Quantitation of Volatile Sulfur Compounds of Swiss Tilsit Cheeses.: Bis(methylthio)methane is quantified as a key sulfur compound in Swiss Tilsit cheese. The study′s findings contribute to the understanding of cheese aroma profiles, aiding in the development of flavor-enhanced dairy products (Fuchsmann et al., 2015).
