Chemical Properties
(+/-)-cis- and trans-3,5-Diethyl-1,2,4-trithiolane has a characteristic sulfur odor.
Occurrence
Reportedly present in garlic (Allium sativum L.).
Preparation
Reportedly produced in a patented process from filamentous fungi by heating them in water at a temperature sufficient to
reduce their nucleic acid content. The resulting aqueous solution is concentrated to separate the solids
Aroma threshold values
For the cis isomer the aroma threshold in water is 0.000032 ppm and for the trans isomer, 0.000015 ppm
(water)
