TITLE 21--FOOD AND DRUGS
CHAPTER I--FOOD AND DRUG ADMINISTRATION, DEPARTMENT OF HEALTH AND HUMAN
SERVICES (CONTINUED)
PART 146 CANNED FRUIT JUICES--Table of Contents
Subpart B Requirements for Specific Standardized Canned Fruit Juices and
Beverages
Sec. 146.132 Grapefruit juice.
(a) Identity--(1) Description. Grapefruit juice is the unfermented
juice, intended for direct consumption, obtained by mechanical process
from sound, mature grapefruit (Citrus paradisi Macfadyen) from which
seeds and peel (except embryonic seeds and small fragments of seeds and
peel which cannot be separated by good manufacturing practice) and
excess pulp are removed and to which may be added not more than 10
percent by volume of the unfermented juice obtained from mature hybrids
of grapefruit. The juice may be adjusted by the addition of the optional
concentrated grapefruit juice ingredients specified in paragraph (a)(2)
of this section, but the quantity of such concentrated grapefruit juice
ingredient added shall not contribute more than 15 percent of the
grapefruit juice soluble solids in the finished food. The grapefruit
pulp, grapefruit oil, and grapefuit essence (components derived from
grapefruit) content may be adjusted in accordance with good
manufacturing practice. The juice may have been concentrated and later
reconstituted with water suitable for the purpose of maintaining
essential composition and quality factors of the juice. It may be
sweetened with the dry nutritive sweeteners referred to in paragraph
(a)(2)(iii) of this section. If the grapefruit juice is prepared from
concentrate, such sweeteners, in liquid form, referred to in paragraph
(a)(2)(iii) of this section, also may be used. When prepared from
concentrated grapefruit juice, exclusive of added sweeteners, the
finished food contains not less than 10 percent, by weight, of soluble
solids taken as the refractometric sucrose value (of the filtrate),
corrected to 20 [deg]C, and corrected for acidity by adding
(0.012+0.193x-0.0004x\2\), where x equals the percent anhydrous citric
acid in the sample, to the refractometrically obtained sucrose value by
the first method prescribed in ``Correction of Refractometer Sucrose
Readings for Citric Acid Content for Lemonade,'' by Yeatman, Senzel, and
Springer, ``Journal of the Association of Official Analytical
Chemists,'' vol. 59 p. 368 (1976). Copies are available from the AOAC
INTERNATIONAL, 481 North Frederick Ave., suite 500, Gaithersburg, MD
20877, or available for inspection at the National Archives and Records
Administration (NARA). For information on the availability of this
material at NARA, call 202-741-6030, or go to: http://www.archives.gov/
federal--register/code--of--federal--regulations/ibr--locations.html.
The food may contain one or any combination of the optional ingredients
specified in paragraph (a)(2) of this section. Grapefruit juice, as
defined in this paragraph, may be preserved by heat sterlization
(canning), refrigeration, or freezing. When sealed in a container to be
held at ambient temperatures, it is so processed by heat, before or
after sealing, as to prevent spoilage.
(2) Optional ingredients. The optional ingredients referred to in
paragraph (a)(1) of this section are:
(i) Concentrated grapefruit juice (grapefruit juice from which part
of the water has been removed).
(ii) Water and/or grapefruit juice to reconstitute concentrated
grapefruit juice in the manufacture of grapefruit juice from
concentrate.
(iii) One or any combination of two or more of the dry or liquid
forms of
[[Page 448]]
sugar, invert sugar sirup, dextrose, glucose sirup, and fructose.
Sweeteners defined in part 168 of this chapter shall be as defined
therein.
(3) Labeling. (i) The name of the food is:
(a) ``Grapefruit juice'' (1) if the food is prepared from
unconcentrated, undiluted liquid extracted from mature grapefruit; or
(2) if the food is prepared from unconcentrated, undiluted liquid
extracted from mature grapefruit to which concentrated grapefruit juice
is added to adjust soluble solids as provided for in paragraph (a)(1) of
this section.
(b) ``Grapefruit juice from concentrate'' (1) if the food is
prepared from concentrated grapefruit juice and water and/or grapefruit
juice; or (2) if the food is prepared from grapefuit juice from
concentrate and grapefruit juice. The words ``from concentrate'' shall
be shown in letters not less than one-half the height of the letters in
the words ``grapefruit juice.''
(ii) If any nutritive sweetener is added, the principal display
panel of the label shall bear the statement ``Sweetener added.'' If no
sweetener is added, the word ``unsweetened'' may immediately precede or
follow the words ``Grapefruit Juice'' or ``Grapefruit Juice from
Concentrate.''
(iii) Label declaration. Each of the ingredients used in the food
shall be declared on the label as required by the applicable sections of
parts 101 and 130 of this chapter.
(b) [Reserved]
(c) Fill of container. (1) The standard of fill of container for
grapefruit juice, except when the food is frozen, is not less than 90
percent of the total capacity of the container as determined by the
general method for fill of container prescribed in Sec. 130.12(b) of
this chapter.
(2) Compliance is determined as specified in Sec. 146.3(g)(2).
(3) If the grapefruit juice fails to meet the standard of fill as
prescribed in paragraphs (c) (1) and (2) of this section, the label
shall bear the general statement of substandard fill specified in Sec.
130.14(b) of this chapter, in the manner and form therein prescribed.
