                        TITLE 21--FOOD AND DRUGS
 
CHAPTER I--FOOD AND DRUG ADMINISTRATION, DEPARTMENT OF HEALTH AND HUMAN 
                          SERVICES (CONTINUED)
 
PART 170_FOOD ADDITIVES--Table of Contents
 
                      Subpart A_General Provisions
 
Sec.  170.3  Definitions.


    For the purposes of this subchapter, the following definitions 
apply:
    (a) Secretary means the Secretary of Health and Human Services.
    (b) Department means the Department of Health and Human Services.
    (c) Commissioner means the Commissioner of Food and Drugs.
    (d) As used in this part, the term act means the Federal Food, Drug, 
and Cosmetic Act approved June 25, 1936, 52 Stat. 1040 et seq., as 
amended (21 U.S.C. 301-392).
    (e)(1) Food additives includes all substances not exempted by 
section 201(s) of the act, the intended use of which results or may 
reasonably be expected to result, directly or indirectly, either in 
their becoming a component of food or otherwise affecting the 
characteristics of food. A material used in the production of containers 
and packages is subject to the definition if it may reasonably be 
expected to become a component, or to affect the characteristics, 
directly or indirectly, of food packed in the container. ``Affecting the 
characteristics of food'' does not include such physical effects, as 
protecting contents of packages, preserving shape, and preventing 
moisture loss. If there is no migration of a packaging component from 
the package to the food, it does not become a component of the food and 
thus is not a food additive. A substance that does not become a 
component of food, but that is used, for example, in preparing an 
ingredient of the food to give a different flavor, texture, or other 
characteristic in the food, may be a food additive.

[[Page 6]]

    (2) Uses of food additives not requiring a listing regulation. Use 
of a substance in a food contact article (e.g., food-packaging or food-
processing equipment) whereby the substance migrates, or may reasonably 
be expected to migrate, into food at such levels that the use has been 
exempted from regulation as a food additive under Sec.  170.39, and food 
contact substances used in accordance with a notification submitted 
under section 409(h) of the act that is effective.
    (3) A food contact substance is any substance that is intended for 
use as a component of materials used in manufacturing, packing, 
packaging, transporting, or holding food if such use is not intended to 
have any technical effect in such food.
    (f) Common use in food means a substantial history of consumption of 
a substance for food use by a significant number of consumers.
    (g) The word substance in the definition of the term ``food 
additive'' includes a food or food component consisting of one or more 
ingredients.
    (h) Scientific procedures include those human, animal, analytical, 
and other scientific studies, whether published or unpublished, 
appropriate to establish the safety of a substance.
    (i) Safe or safety means that there is a reasonable certainty in the 
minds of competent scientists that the substance is not harmful under 
the intended conditions of use. It is impossible in the present state of 
scientific knowledge to establish with complete certainty the absolute 
harmlessness of the use of any substance. Safety may be determined by 
scientific procedures or by general recognition of safety. In 
determining safety, the following factors shall be considered:
    (1) The probable consumption of the substance and of any substance 
formed in or on food because of its use.
    (2) The cumulative effect of the substance in the diet, taking into 
account any chemically or pharmacologically related substance or 
substances in such diet.
    (3) Safety factors which, in the opinion of experts qualified by 
scientific training and experience to evaluate the safety of food and 
food ingredients, are generally recognized as appropriate.
    (j) The term nonperishable processed food means any processed food 
not subject to rapid decay or deterioration that would render it unfit 
for consumption. Examples are flour, sugar, cereals, packaged cookies, 
and crackers. Not included are hermetically sealed foods or manufactured 
dairy products and other processed foods requiring refrigeration.
    (k) General recognition of safety shall be determined in accordance 
with Sec.  170.30.
    (l) Prior sanction means an explicit approval granted with respect 
to use of a substance in food prior to September 6, 1958, by the Food 
and Drug Administration or the United States Department of Agriculture 
pursuant to the Federal Food, Drug, and Cosmetic Act, the Poultry 
Products Inspection Act, or the Meat Inspection Act.
    (m) Food includes human food, substances migrating to food from 
food-contact articles, pet food, and animal feed.
    (n) The following general food categories are established to group 
specific related foods together for the purpose of establishing 
tolerances or limitations for the use of direct human food ingredients. 
Individual food products will be included within these categories 
according to the detailed classifications lists contained in Exhibit 33B 
of the report of the National Academy of Sciences/National Research 
Council report, ``A Comprehensive Survey of Industry on the Use of Food 
Chemicals Generally Recognized as Safe'' (September 1972), which is 
incorporated by reference. Copies are available from the National
