United States Department of Agriculture United States Standards Agricultural Marketing for Grades of Service Fruit and Frozen Concentrated Vegetable Division Blended Grapefruit Juice Processed Products Branch and Orange Juice Effective date September 21, 1968 This is the first issue, as amended, of the United States Standards for Frozen Concentrated Blended Grapefruit Juice and Orange Juice. This issue contains all of the requirements of the first issue, effective December 10, 1951 and the amendments published in the FEDERAL REGISTER of December 9, 1953 (18 FR 7999) to become effective September 21, 1968. Voluntary U.S. grade standards are issued under the authority of the Agricultural Marketing Act of 1946, which provides for the development of official U.S. grades to designate different levels of quality. These grade standards are available for use by producers, suppliers, buyers, and consumers. As in the case of other standards for grades of processed fruits and vegetables, these standards are designed to facilitate orderly marketing by providing a convenient basis for buying and selling, for establishing quality control programs, and for determining loan values. The standards also serve as a basis for the inspection and grading of commodities by the Federal inspection service, the only activity authorized to approve the designation of U.S. grades as referenced in the standards, as provided under the Agricultural Marketing Act of 1946. This service, available as on-line (in-plant) or lot inspection and grading of all processed fruit and vegetable products, is offered to interested parties, upon application, on a fee-for-service basis. The verification of some specific recommendations, requirements, or tolerances contained in the standards can be accomplished only by the use of on-line inspection procedures. In all instances, a grade can be assigned based on final product factors or characteristics. In addition to the U.S. grade standards, grading manuals or instructions for inspection of several processed fruits and vegetables are available upon request for a nominal fee. These manuals or instructions contain detailed interpretations of the grade standards and provide step-by-step procedures for grading the product. Grade standards are issued by the Department after careful consideration of all data and views submitted, and the Department welcomes suggestions which might aid in improving the standards in future revisions. Comments may be submitted to, and copies of standards and grading manuals obtained from: Chief, Processed Products Branch Fruit and Vegetable Division, AMS U.S. Department of Agriculture P.O.

Note: Compliance with the provisions of these standards shall not excuse failure to comply with the provisions of the Federal Food, Drug, and Cosmetic Act, or with applicable State laws and regulations. §52.1311 Product description. Frozen concentrated blended grapefruit juice and orange juice is the frozen product prepared from a combination of concentrated, unfermented juices obtained from sound, mature grapefruit (Citrus paradisi) and from sound, mature fruit of the sweet orange group (Citrus sinensis) and Mandarin group (Citrus reticulata), except tangerines. The fruit is prepared by sorting and by washing prior to extraction of the juices to assure a clean product. The juices may be blended upon extraction of such juices or after concentration and fresh orange juice extracted from sorted and washed fruit, as aforesaid, is admixed to the concentrate. It is recommended that the frozen concentrated blended grapefruit juice and orange juice be composed of the equivalent of not less than 50 percent orange juice in the reconstituted juice; however, in oranges yielding light-colored juice it is further recommended that as much as the equivalent of 75 percent orange juice in the reconstituted juice be used. The concentrated juice is packed in accordance with good commercial practice and is frozen and maintained at temperatures necessary for the preservation of the product. §52.1312 Styles of frozen concentrated blended grapefruit juice and orange juice. (a) Style I, without sweetening ingredient added. The Brix value of the finished concentrate shall be not less than 40 degrees nor more than 44 degrees. (b) Style II, with sweetening ingredient added. The finished concentrate, exclusive of added sweetening ingredient, has a Brix value of not less than 38 degrees; and the finished concentrate, including added sweetening ingredient, shall have a Brix value of not less than 40 degrees but not more than 48 degrees. §52.1313 Grades of frozen concentrated blended grapefruit juice and orange juice. (a) U.S. Grade A or U.S. Fancy is the quality of frozen concentrated blended grapefruit juice and orange juice which reconstitutes properly and of which the reconstituted juice possesses the appearance of fresh juices of such a blend; possesses a very good color; is practically free from defects; possesses a very good flavor; and scores not less than 85 points when scored in accordance with the scoring system outlined in this subpart. 2 (b) U.S. Grade B or U.S. Choice is the quality of frozen concentrated blended grapefruit juice and orange juice which reconstitutes properly and of which the reconstituted juice possesses a good color; is reasonably free from defects; possesses a good flavor; and scores not less than 70 points when scored in accordance with the scoring system outlined in this subpart. (c) Substandard is the quality of frozen concentrated blended grapefruit juice and orange juice that fails to meet the requirements of U.S. Grade B or U.S. Choice. §52.1314 Recommended fill of container. 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 each container be filled with frozen concentrated blended grapefruit juice and orange juice as full as practicable without impairment of quality. §52.1315 Ascertaining the grade. (a) The grade of frozen concentrated blended grapefruit juice and orange juice is ascertained by considering in conjunction with the requirements of the respective grade, the respective ratings for the factors of color, absence of defects, and flavor. (b) The relative importance of each factor which is scored is expressed numerically on the scale of 100. The maximum number of points that may be given such factors are: Factors Points Color ............................ 20 Absence of defects ................. 40 Flavor ........................... 40 Total score ................... 100 §52.1316 Ascertaining the rating for the factors which are scored. The essential variations within each factor which is scored are so described that the value may be ascertained for each factor and expressed numerically. The numerical range within each factor which is score is inclusive (for example, 17 to 20 points means 17, 18, 19, or 20 points). 3 §52.1317 Color. (a) "A" classification. Frozen concentrated blended grapefruit juice and orange juice of which the reconstituted juice possesses a very good color may be given a score of 17 to 20 points. Very good color means that the color is bright, light yellow-orange, and typical of freshly extracted juices of such a blend and is free from any trace of browning indicative of scorching, oxidation, caramelization, or other causes. (b) "B" classification. If the reconstituted juice possesses a good color, a score of 14 to 16 points may be given. Frozen concentrated blended grapefruit juice and orange juice that falls into this classification shall not be graded above U.S. Grade B or U.S. Choice, regardless of the total score for the product (this is a limiting rule). Good color means that the color may range from light yellow to light amber, is fairly typical of freshly extracted juices of such a blend and may be slightly dull or may show traces of browning but is not off color for any reason. (c) "SStd" classification. If the reconstituted juice fails to meet the requirements
