PART 868—GENERAL REGULATIONS AND STANDARDS FOR CERTAIN AGRICULTURAL COMMODITIES
Subpart E—United States Standards for Milled Rice


Terms Defined

§868.301   Definition of milled rice.

Whole or broken kernels of rice (Oryza sativa L.) from which the hulls and at least the outer bran layers have been removed and which contain not more than 10.0 percent of seeds, paddy kernels, or foreign material, either singly or combined.

§868.302   Definition of other terms.

For the purposes of these standards, the following terms shall have the meanings stated below:

(a) Broken kernels. Kernels of rice which are less than three-fourths of whole kernels.

(b) Brown rice. Whole or broken kernels of rice from which the hulls have been removed.

(c) Chalky kernels. Whole or broken kernels of rice which are one-half or more chalky.

(d) Classes. There are seven classes of milled rice. The following four classes shall be based on the percentage of whole kernels, and types of rice:

Long Grain Milled Rice.

Medium Grain Milled Rice.

Short Grain Milled Rice.

Mixed Milled Rice.

The following three classes shall be based on the percentage of whole kernels and of broken kernels of different size:

Second Head Milled Rice.

Screenings Milled Rice.

Brewers Milled Rice.

(1) “Long grain milled rice” shall consist of milled rice which contains more than 25.0 percent of whole kernels of milled rice and in U.S. Nos. 1 through 4 not more than 10.0 percent of whole or broken kernels of medium or short grain rice. U.S. No. 5 and U.S. No. 6 long grain milled rice shall contain not more than 10.0 percent of whole kernels of medium or short grain milled rice (broken kernels do not apply).

(2) “Medium grain milled rice” shall consist of milled rice which contains more than 25.0 percent of whole kernels of milled rice and in U.S. Nos. 1 through 4 not more than 10.0 percent of whole or broken kernels of long grain rice or whole kernels of short grain rice. U.S. No. 5 and U.S. No. 6 medium grain milled rice shall contain not more than 10.0 percent of whole kernels of long or short grain milled rice (broken kernels do not apply).

(3) “Short grain milled rice” shall consist of milled rice which contains more than 25.0 percent of whole kernels of milled rice and in U.S. Nos. 1 through 4 not more than 10.0 percent of whole or broken kernels of long grain rice or whole kernels of medium grain rice. U.S. No. 5 and U.S. No. 6 short grain milled rice shall contain not more than 10.0 percent of whole kernels of long or medium grain milled rice (broken kernels do not apply).

(4) “Mixed milled rice” shall consist of milled rice which contains more than 25.0 percent of whole kernels of milled rice and more than 10.0 percent of “other types” as defined in paragraph (i) of this section. U.S. No. 5 and U.S. No. 6 mixed milled rice shall contain more than 10.0 percent of whole kernels of “other types” (broken kernels do not apply).

(5) “Second head milled rice” shall consist of milled rice which, when determined in accordance with §868.303, contains:

(i) Not more than (a) 25.0 percent of whole kernels, (b) 7.0 percent of broken kernels removed by a 6 plate, (c) 0.4 percent of broken kernels removed by a 5 plate, and (d) 0.05 percent of broken kernels passing through a 4 sieve (southern production); or

(ii) Not more than (a) 25.0 percent of whole kernels, (b) 50.0 percent of broken kernels passing through a 612 sieve, and (c) 10.0 percent of broken kernels passing through a 6 sieve (western production).

(6) “Screenings milled rice” shall consist of milled rice which, when determined in accordance with §868.303, contains:

(i) Not more than (a) 25.0 percent of whole kernels, (b) 10.0 percent of broken kernels removed by a 5 plate, and (c) 0.2 percent of broken kernels passing through a 4 sieve (southern production); or

(ii) Not more than (a) 25.0 percent of whole kernels and (b) 15.0 percent of broken kernels passing through a 512 sieve; and more than (c) 50.0 percent of broken kernels passing through a 612 sieve and (d) 10.0 percent of broken kernels passing through a 6 sieve (western production).

(7) “Brewers milled rice” shall consist of milled rice which, when determined in accordance with §868.303, contains not more than 25.0 percent of whole kernels and which does not meet the kernel-size requirements for the class Second Head Milled Rice or Screenings Milled Rice.

(e) Damaged kernels. Whole or broken kernels of rice which are distinctly discolored or damaged by water, insects, heat, or any other means, and parboiled kernels in nonparboiled rice. “Heat-damaged kernels” (see paragraph (g) of this section) shall not function as damaged kernels.

(f) Foreign material. All matter other than rice and seeds. Hulls, germs, and bran which have separated from the kernels of rice shall be considered foreign material.

(g) Heat-damaged kernels. Whole or broken kernels of rice which are materially discolored and damaged as a result of heating and parboiled kernels in nonparboiled rice which are as dark as, or darker in color than, the interpretive line for heat-damaged kernels.

(h) Objectionable seeds. Seeds other than rice, except seeds of Echinochloa crusgalli (commonly known as barnyard grass, watergrass, and Japanese millet).

(i) Other types. (1) Whole kernels of: (i) Long grain rice in medium or short grain rice, (ii) medium grain rice in long or short grain rice, (iii) Short grain rice in long or medium grain rice, and (2) broken kernels of long grain rice in medium or short grain rice and broken kernels of medium or short grain rice in long grain rice, except in U.S. No. 5 and U.S. No. 6 milled rice. In U.S. No. 5 and U.S. No. 6 milled rice, only whole kernels will apply.

Note: Broken kernels of medium grain rice in short grain rice and broken kernels of short grain rice in medium grain rice shall not be considered other types.

(j) Paddy Kernels. Whole or broken unhulled kernels of rice; whole or broken kernels of brown rice, and whole or broken kernels of milled rice having a portion or portions of the hull remaining which cover one-eighth ( 18 ) or more of the whole or broken kernel.

(l) Seeds. Whole or broken seeds of any plant other than rice.

(m) Types of rice. There are three types of milled rice as follows:

Types shall be based on the length-width ratio of kernels of rice that are unbroken and the width, thickness, and shape of kernels that are broken, prescribed in FGIS instructions.

(n) Ungelatinized kernels. Whole or broken kernels of parboiled rice with distinct white or chalky areas due to incomplete gelatinization of the starch.

(o) Well-milled kernels. Whole or broken kernels of rice from which the hulls and practically all of the germs and the bran layers have been removed.
