European Union and United Kingdom

No EU FL number is on file for 2-Tetrahydrofurfuryl 2-mercaptopropionate. That is not a finding either way. The Union List covers defined flavouring substances, so natural complex materials are handled as flavouring preparations under Parts B to F and never receive a number, and substances used as additives sit under Regulation 1333/2008 instead. Confirm the position before EU or UK use.

JECFA (WHO / FAO)

JECFA number 2093, evaluated at the 76th meeting in 2012. no safety concern at current levels of intake when used as a flavouring agent.
