(b) Granulated brewers milled rice. Granulated brewers milled rice shall be milled rice which has been crushed or granulated so that 95.0 percent or more will pass through a 5 sieve, 70.0 percent or more will pass through a 4 sieve, and not more than 15.0 percent will pass through a 2 1/2 sieve.

(c) Parboiled milled rice. Parboiled milled rice shall be milled rice in which the starch has been gelatinized by soaking, steaming, and drying. Grades U.S. No. 1 to U.S. No. 6, inclusive, shall contain not more than 10.0 percent of ungelatinized kernels. Grades U.S. No. 1 and U.S. No. 2 shall contain not more than 0.1 percent, grades U.S. No. 3 and U.S. No. 4 not more than 0.2 percent, and grades U.S. No. 5 and U.S. No. 6 not more than 0.5 percent of nonparboiled rice. If the rice is: (1) Not distinctly colored by the parboiling process, it shall be considered “Parboiled Light”; (2) distinctly but not materially colored by the parboiling process, it shall be considered “Parboiled”; (3) materially colored by the parboiling process, it shall be considered “Parboiled Dark.” The color levels for “Parboiled Light,” “Parboiled,” and “Parboiled Dark” shall be in accordance with the interpretive line samples for parboiled rice.

(d) Undermilled milled rice. Undermilled milled rice shall be milled rice which is not equal to the milling requirements for “hard milled,” “well milled,” and “reasonably well milled” rice (see § 868.306). Grades U.S. No. 1 and U.S. No. 2 shall contain not more than 2.0 percent, grades U.S. No. 3 and U.S. No. 4 not more than 5.0 percent, grade U.S. No. 5 not more than 10.0 percent, and grade U.S. No. 6 not more than 15.0 percent of well-milled kernels. Grade U.S. No. 5 shall contain not more than 10.0 percent of red rice and damaged kernels (singly or combined) and in no case more than 6.0 percent of damaged kernels.

(e) Glutinous milled rice. Glutinous milled rice shall be special varieties of rice (Oryza sativa L. glutinosa) which contain more than 50 percent chalky kernels. For long grain, medium grain, and short grain milled rice, grade U.S. No. 1 shall contain not more than 1.0 percent of nonchalky kernels, grade U.S. No. 2 not more than 2.0 percent of nonchalky kernels, grade U.S. No. 3 not more than 4.0 percent of nonchalky kernels, grade U.S. No. 4 not more than 6.0 percent of nonchalky kernels, grade U.S. No. 5 not more than 10.0 percent of nonchalky kernels, and grade U.S. No. 6 not more than 15.0 percent of nonchalky kernels. For second head milled rice, grade U.S. No. 1 shall contain not more than 4.0 percent of nonchalky kernels, grade U.S. No. 2 not more than 6.0 percent of nonchalky kernels, grade U.S. No. 3 not more than 10.0 percent of nonchalky kernels, grade U.S. No. 4 not more than 15.0 percent of nonchalky kernels, and grade U.S. No. 5 not more than 20.0 percent of nonchalky kernels. For screenings milled rice, there are no grade limits for percent of nonchalky kernels. For brewers milled rice, the special grade “Glutinous milled rice” is not applicable.

(f) Aromatic milled rice. Aromatic milled rice shall be special varieties of rice (Oryza sativa L. scented) that have a distinctive and characteristic aroma; e.g., basmati and jasmine rice.
