food favor may be given a score of 51 to 60 points. “Good favor" means a fine, distinct, and substantially typical flavor of limeade prepared from freshly expressed lime juice and which ilavor is free from terpenic, oxidized, rancid, or other off flavors. To score in this classification, the limeade shall test not less than 10.5 degrees Brix; shall contain not less than 0.7 gram of acid per 100 ml. of the limeade; may not contain more than 0.025 ml. or less than 0.008 ml. of recoverable oil per 100 ml. of the limeade; and the Brix-acid ratio shall not exceed 18:1

(b) (B) classification. If the prepared limeade possesses a reasonably good flavor & score of 42 to 50 points may be given. Frozen concentrate for limeade 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). “Reasonably good flavor" means a fairly typical flavor of limeade prepared from freshly expressed lime juice and which flavor is practically free from terpenic, oxidized, rancid, or other off flavors and is free from abnormal flavors of any kind. To score in this classification the limeade shall test not less than 10.5 degrees Brix; shall contain not less than 0.7 gram of acid per 100 ml. of the limeade; may not contain more than 0.035 ml, or less than 0.008 inl. of recoverable oil per 100 ml. of the limeade; and the Brix-acid ratio shall not exceed 18:1.

(c) (SStd.) classification. If the prepared Umeade fails to meet the requirements of paragraph (b) of this section, a score of 0 to 41 points may be given. Frozen concentrate for limeade that falls into this classification shall not be graded above "Substandard" regardless of the total score for the product (this is a Umiting rule).

(a) “Brix” means the degree Brix of the limeade when tested with a Brix by

drometer calibrated at 20 degrees C. (68
degrees F.) I used in testing limeade
at a temperature other than 20 degrees

"Official Methods of Analysis of the As-
sociation of Oficial Agricultural Chem-
ists" The degrees Brix of limeade may
be determined by any other method
which gives equivalent results.

(b) “Acid” means the grams of acid (calculated as anhydrous citric acid) per 100 ml. of the prepared limeade determined by titration with standard sodium hydroxide solution using phenolphthalein as an indicator.

(c) “Brix-acid ratio" means the ratio between the degrees "Brix" as determined in this section and the acid in grams per 100 ml. of limeade.

(d) “Dilution factor" is the value obtained by dividing & volume of Umeade by the volume of concentrate for limeade used in its preparation when such limeade is prepared in accordance with the manufacturer's directions. $ 52.2530 Explanation of analyses.

Recoverable oil is determined by the following method:

METHOD (1) Reagents.

Standard bromide-bromate solution prepared and standardized to 0.099N in accordance with Chapter 42, Standard Solutions in the current edition of the AOAC.1 For use add 1 volume of standard solution to 3 volumes of water to make 0.0247N solution. I ml, of 0.0247N solution supplies bromine to react with 0.00085g., or 0.0010 ml., of dUmonene. The solutions are stable for 6 months.
