Application


  • Identification of new strawberry sulfur volatiles and changes during maturation.: Du et al. explore sulfur volatiles in strawberries, noting the presence of ethyl 3-(methylthio)propionate among new compounds discovered. The study provides insights into how these volatiles evolve during fruit maturation, impacting flavor and aroma profiles (Du et al., 2011).

Volatile sulfur compounds (VSCs) play an important role in the aroma profile of fermented beverages. However, because of their low concentration in samples, their analysis is difficult. The headspace solid-phase microextraction (HS-SPME) technique coupled with gas chromatography and mass spectrometry

The aroma profile of Chinese roasted sesame-like flavor type liquor was investigated by means of headspace solid phase microextraction-aroma extract dilution analysis (HS-SPME-AEDA). Sixty-three odor-active regions were detected by HS-SPME-AEDA with flavor dilution (FD) factors >5, and 58 of these

This study investigated the aroma contribution of volatile sulfur compounds (VSCs) in Moutai liquors. The VSCs were analyzed using headspace solid-phase microextraction-gas chromatography-pulsed flame photometric detection (HS-SPME-GC-PFPD). The influences of SPME fibers, ethanol content in the sample, pre-incubation time, and
