(a) General. The factor of character refers to the development of the pods and seeds and to the degree of freedom from tough fiber. "Tough fiber" in frozen okra means any cooked unit that contains tough fibrous development to the extent that the eating quality of the unit is materially affected.

"Good character" means that the units are fleshy and tender, that the seeds are in the early stages of maturity, and that not more than 2 whole pods or 4 cut units (as applicable) per sample unit possess tough fibers.

(c) (B) Classification. Frozen okra that possesses a reasonably good character may be given a score of 24 to 26 points. Frozen okra that falls into this classification shall not be graded above U.S. Grade B, regardless of the total

LOT INSPECTION AND CERTIFICATION

§ 52.1540 Ascertaining the grade of a lot.

The grade of a lot of the processed product covered by these standards is determined by the procedures set forth in the regulations governing inspection and certification of processed fruits and vegetables, processed products thereof, and certain other processed food products (§§ 52.1 to 52.87).

[22 F. R. 3547, May 22, 1957]

(a) "U.S. Grade A" (or "U.S. Fancy") is the quality of canned orange juice that: (1) Shows no coagulation, (2) has a good color, (3) is practically free from defects, (4) possesses a good flavor, and (5) scores not less than 90 points when scored in accordance with the scoring system outlined in this subpart.

(b) "U.S. Grade C" (or "U.S. Standard") is the quality of canned orange juice that: (1) May show a slight coagu

lation, (2) has a fairly good color, (3) is fairly free from defects, (4) possesses a fairly good flavor, and (5) scores not less than 80 points when scored in accordance with the scoring system outlined in this subpart.

(c) "Substandard" is the quality of canned orange juice that fails to meet the requirements of U.S. Grade C.

FILL OF CONTAINER

§ 52.1554 Recommended fill of con

tainer.

The recommended fill of container is not incorporated in the grades of the finished product since fill of container, as such, is not a factor of quality for the purposes of these grades. It is recommended that the container be as full of orange juice as practicable.

FACTORS OF QUALITY

§ 52.1555 Ascertaining the grade of a sample unit.

(a) General. The grade of a sample unit of canned orange juice is ascertained by considering the degree of any coagulation, which is not scored; the ratings for the factors of color, defects, and flavor which are scored; the total score; and the limiting rules which may be applicable.

(b) Factors rated by score points. The relative importance of each scoring factor is expressed numerically on the scale of 100. The maximum number of points that may be given such factors

so that these color standards become points of reference.

(2) Such comparison is made under an artificial light source of approximately 150 candela intensity and having a spectral quality approximating that of daylight under a moderately overcast sky and a color temperature of 7500 degrees Kelvin, 200 degrees.

(3) The USDA Orange Juice Color Standards range from yellow-orange to yellow color, with USDA OJ 1 being the most orange color in the series.

(b) Procedure in evaluating color. (1) Place the product in a clear glass test tube of 1 inch diameter.

(2) Arrange color standards in a test tube rack or similar device so that light coming from above strikes the standards at a 45 degree angle. The standards are inclined at a 45 degree angle against a neutral grey background. Observe the standards and product at right angles to the tubes.

(3) Classify the juice by inserting the tube of juice where it best fits in the series of color standards. Orange juice differing in color and brightness from the most nearly matching USDA Orange Juice Color Standard is evaluated by considering the amount of difference and its effect on the total appearance of the juice.

(c) Availability of color standards. The USDA Orange Juice Color Standards cited in this section are official color standards which may also be applied to other orange juices. Information regarding these color standards, and their availability, may be obtained from: Processed Products Standardization and Inspection Branch,

Fruit and Vegetable Division,
Agricultural Marketing Service,
U.S. Department of Agriculture,
Washington, D.C., 20250.

(d) (A) Classification. Canned orange juice that has a good color may be given a score of 36 to 40 points. "Good color" means a bright yellow to yelloworange color, typical of orange juice color. Canned orange juice that meets this criterion may be assigned score points in accordance with the following schedule:

As compared with USDA Orange
Juice Color Standards:

USDA OJ 2
