No details were provided on the contents of the proposed definition amid a long awaited explanation of UPFs as a guide for the US food industry. However, the lack of a “standardised” definition has made it harder to keep research consistent across the federal government, HSS added. In terms of GRAS, the FDA aims to “modernise” the existing framework by “significantly improving transparency”, according to the HHS. TD Cowen analyst Robert Moskow had a positive view of the proposed GRAS changes, saying the new rules are “relatively accommodative to the food industry given that it only asks for notification rather than pre-market approval or retroactive review of existing self-affirmed GRAS additives”.
