TITLE 21--FOOD AND DRUGS

SERVICES (CONTINUED)
PART 137 CEREAL FLOURS AND RELATED PRODUCTS--Table of Contents
Subpart B Requirements for Specific Standardized Cereal Flours and
Related Products
Sec. 137.300 Farina.
(a) Farina is the food prepared by grinding and bolting cleaned
wheat, other than durum wheat and red durum wheat, to such fineness
that, when tested by the method prescribed in paragraph (b)(2) of this
section, it passes through a No. 20 sieve, but not more than 3 percent
passes through a No. 100 sieve. It is freed from bran coat, or bran coat
and germ, to such extent that the percent of ash therein, calculated to
a moisture-free basis, is not more than 0.6 percent. Its moisture
content is not more than 15 percent.
(b) For the purposes of this section:
(1) Ash and moisture are determined by the methods therefor referred
to in Sec. 137.105(c).
[[Page 389]]
(2) The method referred to in paragraph (a) of this section is as
follows: Use No. 20 and No. 100 sieves, having standard 20.3 centimeter
(8-inch) full-height frames, complying with the specifications for such
cloth set forth in ``Official Methods of Analysis of the Association of
Official Analytical Chemists,'' 13th Ed. (1980), Table 1, ``Nominal
Dimensions of Standard Test Sieves (U.S.A. Standard Series),'' under the
heading ``Definitions of Terms and Explanatory Notes,'' which is
incorporated by reference. Copies may be obtained from the AOAC
INTERNATIONAL, 481 North Frederick Ave., suite 500, Gaithersburg, MD
20877, or may be 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. Fit a No. 20 sieve
into a No. 100 sieve. Attach bottom pan to the No. 100 sieve. Pour 100
grams of the sample into the No. 20 sieve. Attach cover and hold the
assembly in a slightly inclined position with one hand. Shake the sieves
by striking the sides against the other hand with an upward stroke, at
the rate of about 150 times per minute. Turn the sieves about one-sixth
of a revolution, each time in the same direction, after each 25 strokes.
Continue shaking for 2 minutes. Weigh the material which fails to pass
through the No. 20 sieve and the material which passes through the No.
100 sieve.
