Those substances for which no biological studies are available to judge their safety.
Include those substances for which information is incomplete to “reaffirm safety”. This
means evidence of toxicity has been reported, however the level and manner of current
use the information is insufficient to determine the effect on public health
Substances whose safety is reaffirmed at the level of current use and practice. However
certain uncertainties exist so that additional studies are required.
It includes those substances whose GRAS status was reaffirmed at current level of use.
This means that the available information presented no evidence of toxic hazard at the
level of current use and practice.
Includes all those additives whose GRAS status was reaffirmed. This means that the
available information presented no evidence of toxic hazards of the substance in
question. These substances are generally used according to GMP

In 1972 a committee from Federation of American societies for experimental biology
reviewed the safety of all GRAS substances on the basis of published and other available
information. The committee placed all reviewed substances in five categories.

E-NUMBRING
Number codes for food additives and
are usually found on food labels
throughout the European Union.
Normally each food additive is
assigned a unique number, though
occasionally, related additives are
given an extension ("a", "b", or "i", "ii")
to another E-number.
International Numbering System
