(b) (B) Classification. If the orange Juice from concentrate possesses a good flavor a score of 32 to 35 points may be given. Orange juice from concentrate that falls into this classification shall not be graded above U.S. Grade B, regardless of the total score for the product (this is a limiting rule). “Good flavor" means that the flavor is fairly typical of orange juice extracted from fresh, mature sweet oranges; is free from off flavors of any kind; and meets the following requirements:

(1) Without sweetener style.

graded above Substandard, regardless of the total score for the product (this is a limiting rule). (32 F.R. 10497, July 18, 1967, as amended at 34 PR. 7861, May 17, 1969) EXPLANATIONS AND METHODS OF ANALYSIS $ 52.5690 Definitions of terms and

methods of analysis. (a) Briz. “Brix" means the degrees Brix of orange juice from concentrate when tested with a Brix hydrometer calibrated at 20 degrees C. (68 degrees F.) and to which any applicable temperature correction has been made. The degrees Brix may be determined by any other method which gives equivalent results.

(b) Acid. “Acid” means the grams of total acidity, calculated as anhydrous citric acid, per 100 grams of juice. Total acidity is determined by titration with standard sodium hydroxide solution using phenolphthalein as indicator.

(c) Brix-acid ratio. "Brix-acid ratio" means the ratio between the Brix and the acid as defined in this section.

(d) Recoverable oil. "Recoverable oll" is determined by the following method:

METHOD (1) Reagents.

Standard bromide-bromate solution-pro. pared and standardized to 0.099N in accordance with Chapter 42, Standard Solutions in the current edition of the AOAC.1 For uso, add 1 volume of standard solution to 8 volumes of water to make 0.0247N solution. 1 ml. of 0.0247N solution supplies bromine to react with 0.00085g., or 0.0010 ml., of d-umonene. The solutions are stable for 6 months.

2-Propanol-Reagent grade ACS (American Chemical Society).

Dilute hydrochloric acid-prepared by adding 1 volume of concentrated acid to 2 volumes of water.

Methyl orange indicator-0.1 percant in water.

(2) Apparatus. Electric heater_with recessed refractory top, 500–750 watta.

Still, all glass-500 ml. distillation fast with 24/40 standard taper neck; 200 mm. Graham condenser with 28/16 receiving socket and drip tip; connecting bulb and adapter as shown in Figure 1.

Burette-10 ml. or 25 ml. graduated to 0.1 ml., with easily controllable flow to permit both rapid and dropwise titration.

[blocks in formation]

(3) Determination.

(1) Pipette 25 ml. of well-mixed sample (juice or reconstituted Juice) into the distillation flask containing carborundum chips or glass beads, and add 25 ml. of 2-Propanol.

(11) Distill into a 150 ml. beaker. Continue distilling until solvent ceases to reflux then remove the flask from the heater.

(111) Add 10 ml. of dilute hydrochloric acid and 1 drop of indicator. (An alternative method would be to prepare a solution containing 5 ml. of indicator and 1,000 ml. of dilute hydrochloric acid-then add 10 ml. of this acid-indicator mix to the 150 ml. beaker.)

(iv) Titrate with the dilute bromate solution while stirring. The major portion of the titrant may be added rapidly, but the endpoint must be approached at about 1 drop per second. Disappearance of color indicates the endpoint.

(V) Determine the reagent blank by titrating three separate mixtures of 25 ml. 2Propanol and 10 ml. of dilute hydrochloric acid with indicator-without refilling the burette, Divide the total milliliter of titrant used by three to obtain the average blank. Subtract the average blank thus obtained from the milliliter of titrant used to titrate the distillate.

(vi) Multiply the remainder by 0.004 to obtain the percent recoverable oil by volume in the juice sample. [32 F.R. 10497, July 18, 1967, as amended at 33 F.R. 11887, Aug. 22, 1968; 34 F.R. 7862, May 17, 1969)

LOT COMPLIANCE $ 52.5691 Ascertaining the grade of a

The grade of a lot of orange juice from concentrate 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).

PRODUCT DESCRIPTION, MOISTURE, SIZES $ 52.5761 Product description.

Dried apricots are the halved and pitted fruit of the apricot tree (Prunus armeniaca) from which the greater portion of moisture has been removed. Before packing, the dried fruit is processed to cleanse the fruit and may be sulfured suficiently to retain a characteristic color. § 52.5762 Moisture.

Federal inspection certificates shall indicate the moisture content of the finished product which shall be not more than 26 percent by weight for sizes No. 1, No. 2, and No. 3, and for slabs, and not more than 25 percent by weight for other sizes. $ 52.5763 Sizes.
