Are FEMA flavor safety reviews since 1960 as strict as FDA's?

Research question: What published safety evaluations exist for FEMA Expert Panel GRAS determinations on flavor chemicals since 1960, and how do their review standards and disclosed conflicts compare with FDA food additive petition reviews?

The facts identify several published FEMA evaluations: a 1977 paper on the panel's criteria 2, a 1991 GRAS evaluation of flavoring substances 1, a 2005 procedure for natural flavor complexes updated in 2018 5, a 2023 reassessment of asafetida, garlic and onion oils 14, and a 2025 review that affirmed thirty-five natural flavor complexes 11. The panel reviews published literature together with experimental toxicology, metabolism and safety data 17, and for natural flavor complexes it groups constituents into congeneric groups and assesses intake using the threshold of toxicological concern rather than a full petition-style dossier 89. The company's 10-K says a GRAS review takes 18 to 24 months versus eight or more years for an FDA food additive petition 19, but the facts do not describe FDA petition review standards in detail, and they disclose no conflict-of-interest statements from the evaluations themselves beyond a company's note of its FEMA membership 20. The newest fact is dated 2025, roughly a year and a half before October 2026 11.
