Generally recognized as safe (GRAS): history and description
Abstract
Generally recognized as safe (GRAS), a system for review and approval of ingredients for addition to food, was conceived at a time when the need for a less doctrinaire review of food ingredients was critical. The GRAS approval process for a food ingredient relies on the judgment of "...experts qualified by scientific training and experience to evaluate its safety..." the end product of which is no better or worse than that by FDA, but often more expeditious. The process and requirements for a successful GRAS determination are discussed and compared with that of the food additive petition (FAP) process. The future of the GRAS process is assured by its history of successful performance, bringing safe food ingredients to the consumer in a timely manner.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
