Propyl propane thiosulfonate

StepBS. Two substances, diisopentyl thiomalate (No. 1672) and propyl propane thiosulfonate (No. 1702), were evaluated at this step of the Procedure. The currently estimated daily per capita intakes of both substances are below 1.5 pg/person per day in Europe. Applying the criteria for Step B5 outlined in Annex 5 of the evaluations published after its forty-ninth meeting (Annex 1, reference 131), the Committee concluded that the use of these substances as flavouring agents at their currently estimated levels of intake poses no safety concern. 

Propyl propane thiosulfonate, cf. Figure 1.11, is an active ingredient from Allium spp., like onion and shallot (19). This compound has... 

A new simple analytical method for monitoring propyl propane thiosulfonate in animal feed has been developed. Reversed phase liquid chromatography with UV detection has been used and a previous sample treatment based on solid-liquid extraction has been optimized in order to extract propyl propane thiosulfonate from a feed for laying hens using acetone as extraction solvent.
